Bayesian Engine for Spam / Non-Spam Detection
Bayesian support within the new Spam Filtering system has been completed. Bayesian classification is a mathematical process whereby machines can actually learn. Through repeated exposure to known samples of spam (and non-spam) Bayesian enabled software can learn to recognize patterns. Over time, Bayesian classification techniques grow more and more reliable.

MDaemon supports Bayesian classification through its incorporation of the SpamFilter heuristic software and through use of a "learning" program that is used to rapidly process and index spam and non-spam sample messages. The learning tool, SA-Learn, will be executed by MDaemon at midnight each night. The tool will examine the content of a "known-spam" folder and a "known-non-spam" folder. You provide the folders and the content. Since the Bayesian results improve over time the scoring tends to get more and more accurate.

SA-Learn trusts that the messages you feed it really and truly are spam and/or non-spam. It takes your word that the input data is accurate. Here's what you should do:

Go to the Spam Filtering|Bayesian tab and use the "Pub Folder" buttons to create two public folders - one for false negatives (messages that should have been flagged as spam but weren't) and another folder for false positives (messages that were incorrectly flagged as spam). Make these folders accessible to all your IMAP users. Now, instruct your users to place copies of any false positive or false negative messages that they receive into these public folders. MDaemon will process them through the learning tool at midnight each night. After processing, these messages are automatically deleted.

Improved Backup Server Performance
MDaemon is often used as a backup mail server for one or more domains using its powerful 'Gateway' feature set. MDaemon excels as a backup mail server. However, one of the drawbacks of MDaemon's 'Gateway' feature set is that MDaemon accepts all mail sent to the 'Gateway' domain. This is because MDaemon doesn't actually have a copy of the account list that the primary mail server is using and so it has no idea whether a message is to a valid account or not.

This has all changed. A new 'Verification' tab has been added to the Gateway GUI. With this tab you can configure LDAP query setting and have MDaemon automatically check with an LDAP server to see if an account really exists or not. This has been optimized to work with LDaemon - a free LDAP server from Alt-N Technologies (http://www.ldaemon.com) but will work with any LDAP server. Just configure the new settings to point to an LDAP server that contains 'mail=' attributes.

If the primary mail server is also an MDaemon/LDaemon combination then very little configuration is necessary. Just point the Gateway's LDAP settings at the primary MDaemon's LDAP address book. Be sure to have the primary MDaemon configured to automatically maintain the LDAP address book.

When a message for a Gateway domain arrives, an LDAP query will be performed to see if the address is valid. If so, SMTP processing continues. If not, the recipient is rejected with a 'user unknown' SMTP error.

MDaemon's automatic LDAP address book publishing service will now also publish aliases to the LDAP address book. This is needed to allow the new Gateway verification feature to accept email bound for valid aliases. The installer will trigger an automatic update to your LDAP address book in order to populate it with alias information the next time MDaemon is started.

Back to Top

SSL/STARTTLS Support
Security has been greatly enhanced through the integration of SSL technology directly into the mail server! MDaemon's SMTP, POP, and IMAP engines now support SSL encryption which makes MDaemon the most secure mail server on the market today.

You can configure dedicated ports for SSL connections via new settings on the Setup|Primary Domain|Ports dialog box. However, dedicated ports are not needed. MDaemon will secure the standard SMTP, POP, and IMAP ports using the industry standard STARTTLS command for SMTP and IMAP and the STLS command for POP.

A new 'Security' top-level menu contains the "SSL & Certificates" option which loads the configuration GUI for the SSL functionality.

Back to Top

Spam Filtering Using Spam-Assassin(tm)
Spam filtering using SpamAssassin technology has been integrated into MDaemon. SpamAssassin is a heuristic mail filter that examines email messages using numerous rules in order to compute a 'score'. This score is then used to determine the likelihood of a message being spam. By examining many thousands of known spam messages the rules have been optimized over time and are very reliable in detecting the fingerprint of a spam message.

You can optimize, customize, or add new rules by editing the configuration files which are part of the SpamAssassin software package. For complete information on this and on all that SpamAssassin brand software can do visit http://www.SpamAssassin.org.

A new 'Security' top-level menu contains the "Spam filtering" option which loads the configuration GUI for the SpamAssassin functionality. Also, a SPAM tab has been added to the main GUI which reports all the spam filtering activity. A new log file called MDaemon-SPAM.log will track spam filtering activity. You can elect not to use this new log via a new setting in the logging options dialog. Also, the Misc. Options dialog has a new option to add Spam logging to the Composite log.

SpamAssassin is a trademark of Deersoft, Inc.

Mobile Device Support For WorldClient
Support for WAP devices has been integrated into MDaemon/WorldClient. A new theme using the WML standard has been incorporated into WorldClient's templates directory. This theme will be sent by WorldClient when the requesting device reports that it supports WML. The WAP enabled device must support WAP 1.0 or higher. Users of mobile devices like cellular telephones will be able to easily access their email using WorldClient.

Skinable ComAgent Instant Message Client
We've added skins to ComAgent. This will improve the look-and-feel of ComAgent and allow your users to personalize it to their own tastes. Several sample skins have been included.

Support for MDaemon Groupware
MDaemon has been enhanced to support MDaemon Groupware. MDaemon GroupWare is a separately licensed product which is now available from Alt-N Technologies. With MDaemon GroupWare you will be able to share your Outlook mail folders, calendars, contacts, and more with other MDaemon GroupWare users.

Back to Top

Bandwidth Throttling
A basic system for policing the consumption of bandwidth has been added. A new option available from the Setup menu will allow you to throttle the rate at which sessions progress. The system is calibrated in kilobytes per second (KB/s). A value of ZERO means apply no limit to the speed at which a session progresses (thus making use of the maximum amount of available bandwidth). A value of 10 will force MDaemon to deliberately throttle back on the speed of transmission so as to remain at or very near 10 KB/s.

You can set different rates for each of MDaemon's major services on a per-domain basis. You can also set limits on local connections by selecting "Local traffic" from the drop down box. This will allow you to create special bandwidth settings which will take effect if the connection is either from or to a local IP.

Back to Top

Improved Spam Blocker
When you toggle the option in the Spam Blocker which flags messages with the X-RBL-Warning header, an option to create an IMAP filter rule for each of your accounts will be presented. The process will create a rule for each account that filters mail into the Spam folder. The Spam folder will also be created. If an account already has a rule which checks for the existance of the X-RBL-Warning header then no action will be taken and no rule created for that account. By default, the name of the IMAP folder that the rule creates and uses is 'Spam'.

Back to Top

Attachment Linking
Attachment linking works by removing all the attachments from incoming local email messages and replacing them with URL links. When users read the email they will see that it contains a URL link to the file rather than the file itself.

Normally, automatically extracted attachments are placed within the account's FILES directory. However, it might be useful to group all the attachments for all accounts into a single directory (such as an accessible directory on your web server). The Attachment Linking feature allows you to do this.

When you specify the location to store extracted attachments you can use account macros to create multiple shared directories. For example, '$ROOTDIR$\\Attachments\\$DOMAIN$\\' will group all attachments by domain.

The key here is that attachments are extracted and placed into a directory you specify. You should make certain that the directory is accessible via URL's in HTML formatted email. It could also be accessed via shared drives.

Back to Top

HTTP Compression for WorldClient
WorldClient now supports HTTP gzip and deflate compression. This will provide a noticeable increase in performance for everyone, particularly dialup users. The compression/decompression consumes minimal extra CPU time on the server and clients and typically achieves a 50 to 80 percent compression ratio. HTTP compression is enabled by default but can be disabled.

Back to Top

Spam Blocker for MultiPOP Users
By popular demand, mail collected via MultiPOP will go through the Spam Blocker now. The Spam Blocker option which previously forced DomainPOP collected mail through the Spam Blocker will also push the MultiPOP collected mail through it. Like with DomainPOP collected mail, messages coming in via MultiPOP which match a known spam source will be deleted without trace if so configured via the Spam Blocker options.

Back to Top

Easy/Advanced
Many customers have stated to us that they love our products but are intimidated by the massive volume of configuration possibilities. To help address this concern we've created a 'Easy' operational mode in which MDaemon will hide non-essential GUI elements. 'Easy' mode retains all the account and list settings but hides many other settings in the interest of simplicity.

Toggling between 'Easy' and 'Advanced' mode can be done via the FILE menu.

Back to Top

ODBC Support for Account Storage
It is now possible to store account data in an ODBC accessible database and have MDaemon use that as its account database backend. Previously, only the flat file USERLIST.DAT or an LDAP server could be used for this purpose.

A new configuration screen is available from the Setup menu which will allow you to configure the database type you wish to use (USERLIST.DAT, LDAP, or ODBC) along with whatever special properties might be needed for each type.

Back to Top

XML Contact Synchronization
Address book synchronization between ComAgent/WorldClient/Outlook/WAB has been changed to a new XML based method. LDAP and LDaemon are no longer required in order to synchronize your address book data. The benefits of these changes are less complication in configuring ComAgent and greater performance and stability.

All users of ComAgent must update to ComAgent 6.50 in order to acquire these benefits. Failing to do so could result in the address book synchronization feature within older versions of ComAgent to fail. Users are prompted when they log into ComAgent to update to the latest version automatically.

Back to Top

ODBC Support for Mailing Lists
The mailing list editor has a new tab labeled ODBC. From here you can select a data source, table, and field mappings for MDaemon to link to your mailing list. When messages arrive for your list one or more SQL queries will be performed automatically and the resulting email addresses will be treated as part of the list's membership. You can also add members to your list by inserting them into the database using whatever database tools you are familiar with.

Email to Cell Phone Support for U.S. Customers
Alt-N and Class M Planet, Inc. have entered into an understanding by which each others technologies can be better leveraged. Through its mHook service, Class M Planet, Inc. provides email forwarding services to cellular phone users in the United States. Support for cellular users with an mHook account has been incorporated directly into MDaemon's Content Filtering system making it possible to use the powerful rules based nature of MDaemon's Content Filtering engine to select precisely which emails your user(s) would like sent to their cellular phone via the mHook service. Non-US customers may continue to use the SMS gateway forwarding option which works on a similar principle.

To sign up for the mHook service visit:
http://www.mhook.com/p/mdaemon.shtml

The Content Filter's 'Send message to cell phone' action will bring up a dialog box wherein you can enter your mHook account's forward-to address.

Back to Top

Smarter Message Routing
When MDaemon sends emails using the direct delivery option sometimes MX lookups contain the IP addresses of the MX hosts themselves. MDaemon has long been able to use those IPs to quicken the routing process when the 'Use 'A' record IP addresses found within 'MX' record packets' option was enabled. However, MDaemon did not consider those IPs when removing what are called 'irrelevant RRs' from MX lookup results. Removing irrelevant RRs is critical to prevent mail loops. Sometimes administrators setup their DNS records incorrectly or not in accord with how they configure MDaemon and this leads to looping problems.

In an attempt to cut down on potential mail delivery problems brought about by incorrect configuration of DNS, MDaemon will now consider A record IP data when determining whether an MX record should be considered irrelevant or not. In the past it only considered host names within the MX packet. The 'Use 'A' record IP addresses...' switch mentioned above must be enabled.

Back to Top

Performance Enhancements
Several changes were made to increase overall performance within the software. The biggest of these was that the IP Screening and MDConfig IP connection checking no longer requires the creation of an actual session within the software. So, checking for and dismissing an attempted connection from a banned host is much faster and much less resource intensive.

Back to Top

SSL Support for WorldClient
SSL support has been added natively to the WorldClient web server. Those who are unable or choose not to run WorldClient under IIS now have the security they need built directly into WorldClient. Several controls for enabling and configuring SSL have been added to the WorldClient GUI within MDaemon. SSL support requires that IE 4.0 or newer is installed on the MDaemon machine.

Back to Top

Tarpitting & Automatic IP Screening
A new tab has been added in the Security Settings dialog for Tarpitting and Automatic IP Screening. Tarpitting is a process by which connections are deliberately slowed to a crawl once XX or more RCPT commands have been received. This discourages spammers from trying to relay bulk mail through your server. It is useful mainly when you must be an open relay (such as an ISP using MDaemon to relay mail for downstream clients). Connections from localhost and trusted hosts are exempt. Automatic IP Screening automatically bans specific IP addresses from future connections to your MDaemon if XX or more errors occur in a mail session from that IP. The offending host is banned for XX minutes.

ComAgent Java Edition
We've created a cross-platform Java version of ComAgent. This version should be compatible with any OS that supports Java (such as Mac OS X). ComAgent-Java will provide full access to the instant messaging and WorldClient folder/email access APIs just as our Win32 GUI based version of ComAgent does. ComAgent-Java will not have the address book synchronization capabilities since this feature is completely dependant on Microsoft technology.

The ComAgent download page inside all the WorldClient themes has been updated providing download instructions for ComAgent-Java.

Improved IMAP folder Sharing
The concept of sharing IMAP folders has been completely embraced by MDaemon. MDaemon supports Public Folders (IMAP folders which belong to the 'system' and are shared amongst a group of users) and Shared User Folders (IMAP folders which belong to individual users who wish to share them with others). Access to Public Folders and Shared User Folders is strictly controlled using ACLs (Access Control Lists - see RFC 2086). ACLs support the following permission settings:

Simple Instant Messaging System
A simple and effective instant messaging system, which allows users on your MDaemon server to communicate instantly with other users, has been built into ComAgent. Each of your MDaemon users can download ComAgent by accessing their WorldClient account and navigating to the Options|ComAgent screen. You can, however, elect on a per domain basis not to provide either ComAgent functionality in general or the IM portion of ComAgent specifically by disabling these options from within MDaemon's Setup|WorldClient configuration dialog.

With our IM system you will be able to see which of your fellow MDaemon users are online and ready to receive an IM. You will also be able to start a group conversation involving several MDaemon users at once. These options are available via the right click IM menu selection within ComAgent.

We recognize the reservation which exists within the SMB community at the leadership levels regarding the IM concept. These reservations stem from the lack of centralized accountability with traditional and well-known IM clients. We intend to minimize these concerns in our IM initiatives now and into the future.

For starters, our system is not peer-to-peer. Therefore, every IM transaction is logged in a central location accessible to the MDaemon/WorldClient administrator. This allows the admin to maintain a record of who said what to whom and when. We recognize the importance of this accountability, and this is also the primary reason why we do not currently support other IM clients like ICQ, AOL, and MSN.

Shared Calendaring and Scheduling
WorldClient has been enhanced with a complete system for scheduling appointments, meetings, and memos at either a global or personal setting. You can also import or export the information from WorldClient to Microsoft Outlook.

Ghosts / Terminal Service Support
If you start MDaemon from the command line and pass the /ghost command line switch an engine-less copy of the GUI will start. We call these detached GUIs: ghosts. Since ghosts are detached from the main MDaemon and don't do any mail processing you can usually get better responsive-ness out of them. Ghosts use a green tray icon and say 'Ghost' in the window caption. You can run a ghost through Terminal Services and edit the properties of the actual MDaemon service. Ghost sessions only work under Windows 2000 and MDaemon supports only a single running ghost instance. We will improve upon this in future versions. For a ghost to display logging information within the various services tabs you will need to enable the new logging option 'Log each service into a separate log file.' This option is enabled by default.

Note: In MDaemon 6.0.x this feature was only available in the Pro Version.

Automated Configuration Backup
A system was added which archives all the MDaemon configuration files on demand and at midnight each night. The settings to configure this feature are located on the Miscellaneous Options | Disk tab. You can specify the file specs which will be backed up.

Back to Top

Logging by Service
A new switch was added to the Logging Options which will instruct MDaemon to maintain separate logs by service. For example, with this switch set MDaemon will track SMTP activity into the MDaemon-SMTP.log file and IMAP activity into the MDaemon-IMAP.log file etc. One side effect of these changes is that it is no longer possible to specify an arbitrary file name for the logs so this control has been removed from the Logging Options dialog.

Public Folder Per User Flag System
IMAP public folders can now store flags (i.e. new/unread/deleted) on a per-user basis. With this option enabled IMAP users will not share the same message flags globally with all other users but will maintain their own message flags independent of other users. These flags are stored under the user's mail directory in a folder with the same name as the public folder. A new option has been added to the Public Folders dialog which will let you set whether or not the folder should use per-user flags.

Back to Top

Host Screening
Similar to IP Screening, Host Screening allows you to specify the names of remote hosts that MDaemon will or will not accept mail from. When an incoming SMTP connection specifies the name of the remote server in the EHLO or HELO parameter MDaemon will compare it to the names listed in the Host Screening configuration. If a match is made the session is either allowed or disallowed depending on how you have configured permissions for that particular host.

Smarter Smart Spooling
In the past when a single message was spooled to multiple recipients at the same host MDaemon would abort the entire message transfer if even one of the recipients was refused by the receiving host. This had the effect of preventing messages from being delivered to valid recipients when a single invalid one was in the delivery list. Although this behavior is technically legal it is not very efficient. MDaemon has been changed so that this no longer occurs. Now when MDaemon encounters errors with one or more recipients during message delivery it will continue the delivery process. Afterward, a summary of those recipients which failed will be dispatched back to the originator of the message. As a result of this change the wording within the DELERR.DAT file is no longer appropriate and has been changed. You should delete your existing DELERR.DAT file from the APP directory and restart MDaemon so that a new one with appropriate wording will be created.

Enhanced Spam Blocking
Several new options have been added to the Spam Blocker system to further combat unwanted mail. There have been instances where spammers will relay spam to you through your ISP. When this occurs, the Spam Blocker is fooled because your ISP is usually trusted or is typically not an originator of the spam. To resolve this problem, a new checkbox is present which will configure MDaemon to check the IP addresses found in all the 'Received' headers within SMTP and DomainPOP collected mails.

With this new switch, all the IP’s in the source route of the message will be checked and if any one of them is found to be a known spam source, the message will be flagged or otherwise dealt with according to the Spam Blocker settings.

To further control unwanted mail, new options have been added to allow you to restrict the depth of the new 'Received' header processing to the first XX 'Received' headers within each message.

Vastly Improved WorldClient
Added new features to WorldClient which allows it to act more like a traditional IMAP client. Messages can now be flagged as deleted or undeleted, instead of using a POP-type trash folder. You can now select which IMAP folders you wish to subscribe and to hide the folders you do not wish to see.

By interacting with MDaemon's MultiPOP system, WorldClient has been further enhanced to allow you to configure multiple mail sources from which to pull mail. This gives control to users while still being policed by the MDaemon administrator.

Finally, the folders WorldClient uses for Drafts, Sent, and Trash can be selected and renamed.

All these new capabilities can be configured globally, per-domain, or per-user just like all other user settings in Domains.ini.

Run WorldClient under IIS
WorldClient will now function as Virtual Directory under IIS, as well as using its own built in web server, if you desire.

Back to Top

Configuration Caching
MDaemon now uses an in memory caching system for the settings found in many of the .ini and .dat files in the App directory. This system will improve performance considerably but changes made manually or directly to those files while MDaemon is running will not be reflected in the program until MDaemon is reloaded or it detects RELOADCACHE.SEM.

Back to Top

Improved List Subscribe/Unsubscribe
A system has been added whereby special email addresses will be available for list users to easily subscribe and unsubscribe to your mailing lists. In the Misc. Options screen you will find a switch that says:

Honor '[List]-Subscribe' and '[List]-Unsubscribe' addresses

For example: suppose you have a list called List@altn.com. People will be able to subscribe/unsubscribe to your list by sending an email message to List-Subscribe@altn.com and List-Unsubscribe@altn.com. The content of the subject and message body is irrelevant. Also, when this feature is active MDaemon will insert the following header into all list messages:

List-Unsubscribe: <mailto:[List]-Unsubscribe@domain.com>

Some mail clients can pick up on this and make an UNSUBSCRIBE button available to users automatically.

Back to Top

Improved Import/Export Capabilities
By selecting the export option and choosing a comma delimited format, MDaemon will export more account information now then in previous versions, including forwarding and auto responder settings. The import process has been enhanced to accept comma delimited files, which may now contain many more fields than in the past. The first line of the comma delimited file is expected to be a base line giving the names and sequence of the fields in subsequent lines.

Back to Top

Improved Command Processing
All the control commands that MDaemon processes for mailing lists and catalogs can now be sent in the message subject in addition to the former method of being contained in the message body.

WebAdmin
Support for Alt-N's next generation of web-based configuration has been integrated into MDaemon. WebAdmin replaced WebConfig as the tool of choice for web-based remote configuration. You can remove the WebConfig directory from within your MDaemon directory structure using the Windows Explorer.

Within the MDaemon GUI, all references to WebConfig have been changed to WebAdmin. WebAdmin continues to use the WebConfig permissions settings you have already put in place for your users and domains. To view documentation or obtain the free download of WebAdmin please go to the following URL:

http://www.altn.com/Products/Default.asp?product_id=WebAdmin

Back to Top

Enhanced MultiPOP Collection Options
A new mail collection method has been added for MultiPOP mail. You can now elect to collect this sort of mail 'dynamically'. This means that MultiPOP mail for a particular user will be collected the next time that user checks his local MDaemon mailbox either via POP, IMAP, or WorldClient.

It's important to note that when a user connects to MDaemon to check for new mail, this act *initiates* a MultiPOP collection event. Messages collected by that event will not be available to the user until the *next* time they check for new messages.

In order to further reduce the load which extensive use of MultiPOP can sometimes place on MDaemon, an option to restrict the number of MultiPOP collections per user per hour and an option to place XX minutes between back-to-back MultiPOP collection events has been added. Additionally, when you specify DomainPOP or MultiPOP hosts to collect mail, you can override the default outbound POP port by appending a new port value to the host name. For example, using 'mail.altn.com' as a MultiPOP host will connect to that host using the default outbound POP port, while using 'mail.altn.com:523' will connect to that host on port 523.

LDaemon LDAP Server Support
Support for LDaemon has been integrated into MDaemon. LDaemon is an LDAPv3 server for Windows NT/2000. It is distributed as a separate download and installed in plug-in fashion. You can acquire LDaemon here:

http://www.altn.com/LDaemon/

Several controls have been placed within the GUI to allow users to start, stop, and monitor the status of LDaemon, including a configurable command line for starting up LDaemon. This optional configuration setting allows you to start the LDaemon service with any or all of the LDAP server's command line switches. For example: "-h ldap://:1001" would start LDaemon using port 1001, rather than the default port of 389.

With LDaemon, you will have a corporate-wide global address book capability which is compatible with virtually all modern email clients, including Microsoft Outlook, Outlook Express, and Eudora.

Automatic Gateway Creation Based on MX Records
One of the more advanced features found in SendMail and other servers is the ability to relay mail based on MX records.

If MDaemon sees that it is a valid MX host for 'arvelh.com', a gateway domain for 'arvelh.com' will be automatically created and mail for all users at 'arvelh.com' will be accepted. The mail will be stored in a special folder and spooled to higher level MX hosts at each remote mail processing interval.

The automatically created gateway will be no different than any of the other gateway you would create yourself. A message to the postmaster will be dispatched each time a gateway is automatically created. This feature can be controlled by switch settings found in the SETUP|RELAY/TRUSTS/REVERSE LOOKUP dialog on the Automatic Gateways tab. This feature effectively allows you to be a backup server for another domain by simply configuring the DNS system to use your IP as an alternate MX host.

CAUTION: Spammers could take advantage of this powerful feature by carefully configuring their DNS server to list YOUR IP as one of their MX hosts.

A basic system to secure this feature has been put in place. You can use controls found in the Automatic Gateways tab to have MDaemon send a confirmation request to the email address of your choice. These confirmation requests must be replied to within a specified number of minutes or the automatically created gateway will be removed.

Public Folders
Support for public IMAP folders has been added. Public folders are extra folders which are available to IMAP users in addition to their private IMAP folders. A new menu and toolbar option allows you to load the Public Folders editor. From here you can create new public folders and assign an 'access list' to each of them.

All public folders are stored in the \\Public Folders\\ directory within the MDaemon directory hierarchy. Public folders are prefixed with a user-defined sequence of up to 20 characters, for example, '#' or 'Public-'. This is to help users distinguish between public and private folders from within their email client software. You can configure this character sequence from within the Public Folders editor.

When IMAP users access their folder list they will see all their private mail folders and will share any public folders to which they have access with other users who have similar access. In this way mail directories can be shared while permitting each mail user access to the mail server under their individual logon credentials.

Once a public folder has been created you can use the Content Filter to setup criteria by which certain messages are moved into that folder. For example, it might be useful to make a rule such that messages containing 'support@mydomain.com' in the TO: header should be moved into the 'Support' public folder. A new Content Filter action 'Move to public folder' has been added to ease this process.

The mailing list editor will allow you to configure a public folder for use with the mailing list. If you enable this feature then a copy of each incoming list message will be placed into the specified public folder.

LDAP Database Capabilities
New controls in the LDAP dialog will allow you to switch MDaemon to use an LDAP server for the account data storage rather than a USERLIST.DAT disk file. This will allow multiple MDaemon servers to access the same user data and facilitate load balancing.

Back to Top

Custom Mail Queue Support
A new editor has been added to the GUI for configuring new mail queues; this supports custom local and remote mail queues to allow MDaemon to monitor several locations from which to send mail. You can also specify that a queue is 'temporary', to be used once at the next scheduled mail processing interval, and then removed from the mail queue list. This feature will become particularly useful in an upcoming version which will support multiple schedules.

Back to Top

IMAP Server Side Mail Rules
IMAP mail rules allow you to maintain rules on the server and have MDaemon route new messages into IMAP folders as they arrive. IMAP server-side mail rules can be set by using a new tab in the Account Editor. Users can maintain their own rules by requesting a special form via a new email command (see HELP.DAT) or by using WebConfig.

Back to Top

LDAP Address Book Support
LDAP address book support has been added. With this option enabled MDaemon will automatically mirror account email address and real names to your LDAP server. You can then point an LDAP enabled mail client to use this LDAP server as an address book.

When LDAP support is enabled, MDaemon will automatically configure WorldClient to use MDaemon's LDAP server for its address book.

Back to Top

IMAP Engine
MDaemon now supports the IMAP protocol. Now you can take advantage of this more modern mail access protocol using mail clients which support it.

The IMAP engine includes a special option in the Timeouts dialog. The option is 'IMAP NOOP Commands Trigger 1 Minute Inactivity Timeout'. When active, this setting reduces IMAP timeouts to 1 minute if a NOOP command is encountered. This is to prevent what a lot of IMAP clients are doing - issuing NOOP commands simply to keep sessions alive unnecessarily. Use of this switch will greatly reduce the resources consumed by a widely deployed IMAP based mail site.

Back to Top

Multiple Domain Support
Full support for multiple domains has been completed - this introduces a wealth of new features and GUI changes. Full support for multiple domains is built around the concept of a 'primary domain' and one or more 'secondary domains'. MDaemon maintains local mailbox directories for all accounts within the primary and secondary domains; therefore, it is no longer necessary to run multiple copies of MDaemon in order to service multiple domains in this fashion.

To create a mail account or mailing list for a secondary domain, you simply specify the domain information. Key features on a PER DOMAIN basis: accounts, lists, and domain security settings (ie: IP Screen and IP Shield). However, several features such as the Domain POP 'Real Name Matching' are tied exclusively to the primary domain.

MDaemon allows an association of an IP address with the primary and each secondary domain and will automatically detect the IP address that an incoming connection is attempting to reach by using the appropriate domain name.

Example of multiple domains and accounts configured:

Domain = altn.com
IP = 1.1.1.1
Email = arvel@altn.com
POP logon = arvel
POP password = ALTN

Domain = arvelh.com
IP = 2.2.2.2
Email = arvel@arvelh.com
POP logon = arvel
POP password = ARVELH

If a connection is made to IP = 1.1.1.1, MDaemon will answer as 'altn.com'.

If a connection is made to IP = 2.2.2.2, MDaemon will answer as 'arvelh.com'.

If arvel@arvelh.com were to connect to a wrong IP address of 1.1.1.1 to check his mail, he will need to supply his POP logon AND domain name in the POP logon field to gain access. This is the only way MDaemon will know which 'arvel' is trying to access mail.

If an account connects to the IP address for his domain, he will need to specify only his POP logon value; otherwise, he must specify his POP logon value and his domain name. Therefore, the support for servicing multiple domains can be accomplished by using a single multi-homed IP address.

However, many email clients on the market today will not allow the '@' symbol to be used in the POP logon field; therefore, MDaemon's default delimiter character is '$', rather than '@'. The solution, 'arvel$arvelh.com', rather than 'arvel@arvelh.com', however arvel@arvelh.com will still work if your email client will allow it.

** The delimiter character can be set to any value by editing the [Special] POPDelimiterChar=XXXX key inside the MDaemon.ini file. This value can be up to 10 chars long - possibly providing a string of characters that serves as the delimiter. For example, using .at. will allow you to make POP logon values of 'arvel.at.arvelh.com'.

Unique Address Book for each Domain
A new switch was added to the WorldClient GUI. This switch allows you to have MDaemon store the public address book for each domain in a unique file. If you enable this switch the public address book file will be "domainname".xml. With this switch enabled "domainname" will not share public contact information with other domains.

GUI Update
The primary MDaemon GUI has been redesigned as a multi-tabbed style interface. This new design increases the efficiency of the software and compartmentalizes what can sometimes be an overwhelming amount of on-screen information. Several tabs, which run across the bottom of the screen, separate out the various services which log information. A composite view is also possible via the Windows menu. The composite view allows you to select one or more services for combined logging into a single window. You can use a new set of controls in the Misc. Options screen to select which services should be logged into the composite view window.
