MDaemon Primary Domain Configuration

Introduction

The MDaemon primary domain can be run safely and securely with its default configuration, as it comes out of the box. This HOWTO summarizes some of the things you can alter as needs present themselves.

Requirements

There is a lot to know about the primary domain. Grow with your needs. MDaemon is almost an install-and-forget-it type of product. The defaults for domains are suitable for most installations. When needs arise, learn what you need to know. Of course, you could read the whole MDaemon manual for fun and learn it all now.

How To

To configure the primary domain:

  1. Use the Primary Domain command from the Setup menu. This displays a dialog with a lot of tabs for different types of configuration data.
  2. Click on the Domain/ISP tab. You can use this tab to set or change the name of your primary domain. Changing the domain name also changes the domain for all of the accounts in the domain, starting with version 6.7.
  3. Click on the Ports tab. Generally speaking you want to leave this information alone. These are the industry standard ports used for sending and receiving email. You might change these if you are using proxies on your network, which is beyond the scope of this HOWTO.
  4. Click on the DNS tab. Domain Name Servers give MDaemon the information it needs to find other mail servers on the Internet. MDaemon uses DNS to send and receive mail and for various security and spam checks, among other things. This tab lets you define the Domain NameDomain Name Servers MDaemon uses for handling email. If your Windows host has DNS services running, just use the check box named Try to use DNS servers defined in Windows TCP/IP Settings. You can also enter a backup DNS to use if the Windows-defined DNS servers are slow or fail.
  5. Click on the Timers tab. Timers control how long MDaemon attempts to do things. For example, it may try for 30 seconds to connect to another server before giving up. The timing values on this tab are averages based on industry experience. You can change them if you have trouble with certain types of connections. This tab also has controls for setting the maximum number of “hops” one message can try before MDaemon quits trying to send it.
  6. Click on the Sessions tab. Sessions control how many simultaneous connections MDaemon can make to other email servers and clients. The values in this tab can be raised or lowered depending on the application of MDaemon, the speed of your network connection and the number of users account MDaemon is servicing.
  7. Click on the Pruning tab. Pruning helps you control the amount of disk space being used for the accounts and email on your server. You can set durations to keep inactive accounts and old mail. After the specified time, MDaemon deletes the accounts and messages.
  8. Click on the Directories tab. These are the directories (folders) where MDaemon keeps its queues, bad messages and the like.
  9. Click on the POP Check tab. A POP check means an account must check its mail before being able to send mail. If you are using DomainPOP and your ISP requires POP before SMTP, then enter your POP account information here.
  10. Click on the Archival tab. Set up archiving if you want to keep copies of all incoming and outgoing email. You can specify where to store the messages.
  11. Click on the Unknown Mail tab. On this tab you can configure how MDaemon handles mail sent to unknown accounts on your server. Spammers often send to randomly-generated account names, in the hopes of making some contacts.
