DNS Configuration for a Mail Server

Before a mail server is ready to be put in service, some DNS configuration is necessary for the domain(s) on the server so that mail can be sent and received.

Sending Your First Email

Once everything is set up, it's time to test things by sending your first email.


A mail server also requires specific ports to be opened to the outside world. Therefore, if you have a firewall sitting in front of your network, or your mail server, you'll want to open the following ports:

  • 25 - Commonly used for SMTP traffic.
  • 53 - DNS Resolution. NOTE: Port 53 is used for DNS only. If DNS is not run on the SmarterMail server, this port does not need to be open.
  • 80 - Used to access SmarterMail's web client. Also used by EAS.
  • 110 - Used for POP connections made to the server.
  • 143 - Used for IMAP connections made to the server.
  • 389 - Used for LDAP connections to the server.
  • 443 - Used to access SmarterMail's web client over SSL. Also used by EAS.
  • 465 - SSL/TLS SMTP Port.
  • 587 - Submission Port - Commonly used as an alternative port number for SMTP traffic (supports SSL/TLS).
  • 993 - SSL/TLS IMAP Port.
  • 995 - SSL/TLS POP Port.
  • 50099 - Used for XMPP (live chat) connections.
