How to Configure SSL Settings

Axigen supports SSL connections for all its TCP based modules (SMTP, POP3, IMAP, WebMail). Here's how to use an SSL encrypted connection through a secure (SSL) socket:

Clients can connect on secure ports for each service. Default protocol secure ports are:

• IMAPS: 993
• POP3S: 995
• SMTPS: 465
• HTTPS: 443

In order to create a secure socket in Axigen, you must create a listener on the corresponding port for the specific service you want to secure. Login into WebAdmin, and go to the desired service's context (WebAdmin → Services → specific service). Press the Add listener button and make the following settings:

• Type the IP of the network interface on which you want the listener to be bound and the corresponding port, according to the list above
• Press the Quick Add button
• Click Edit for this newly created listener
• Switch to the SSL Settings tab
• Check the Enable SSL for this listener option
• Set the Path to certificate file to point to the SSL certificate(for example the one you can create using LetsEncrypt as described here
• Depending on the operating system, the appropriate values are:
  • for Linux: /var/opt/axigen/letsencrypt/<domain name>/cert.pem
  • for Windows: C:\Program Files\Axigen Mail Server\letsencrypt\<domain name>cert.pem
     
• Click on the Show SSL Configuration and complete the path to the Certificate authorities file
• Depending on the operating system, the appropriate values are:
  • for Linux: /var/opt/axigen/letsencrypt/<domain name>/cert_auth.pem
  • for Windows: C:\Program Files\Axigen Mail Server\letsencrypt\<domain name>cert_auth.pem
• Press the Save Configuration button
