MDaemon 12.0.x : How to configure SSL features for SMTP, POP, and IMAP for MDaemon

This article will explain how to configure SSL features for SMTP, POP, and IMAP within MDaemon.

Note: This article will assume you do not already have an SSL certificate installed, and will be using a self-signed certificate. In the MDaemon console:

  1. Click the Security menu
  2. Click Security Settings...
  3. Click SSL & TLS
  4. Click Enable SSL, STARTTLS, and STLS
  5. Click Enable the dedicated SSL ports for SMTP, IMAP, POP3 servers
    This will enable the dedicated ports specified under Default Domain & Servers. This will not affect clients using STARTTLS and STLS on the default mail ports
  6. Click SMTP server uses STARTTLS whenever possible
    This will enable MDaemon to use the STARTTLS extension for every SMTP message it sends if the server supports STARTTLS
  7. Click DomainPOP/MultiPOP servers use STLS whenever possible
    This will enable the STLS extension whenever possible for DomainPOP/MultiPOP connections

The below procedure will create a self-signed certificate

  1. Type your FQDN within the Host name field
  2. Type your Organization/Company Name
    If you have alternate host names, type them within the Alternative host names field separated by a comma
  3. Select the Encryption key length
  4. Select the Country/Region your server resides in
  5. Click Create certificate
  6. Click OK

    This will restart the SMTP, POP, and IMAP services

Note: If you are using a third party certificate, follow the instructions given by the provider to install it within the Microsoft Management Console (MMC). Once installed, you may omit the steps listed below 'The below procedure will create a self-signed certificate'. Instead, single click the certificate you wish to use and click Ok

Additional Comments

Note: The request and installation of third party SSL certificates is NOT supported by Alt-N Technical Support, and those who choose to use a third party certificate should be aware of all security issues related to installing and using SSL certificates with their Operating System. If you have questions or issues regarding your third party SSL certificate, please contact the vendor from whom you purchased the certificate.
