You can specify the IMSS server ports that clients will use to retrieve POP3 traffic. The default POP3 port is 110. However, if your users need to access a POP3 server through an authenticated connection (through the APOP command or using NTLM), you may also set up a dedicated connection and assign a custom port.

Procedure

  1. Go to Administration → IMSS Configuration → Connections.
    The Components tab appears by default.
  2. Click the POP3 tab.
  3. Do one of the following:
    • To accept any POP3 server requested by a user, specify the incoming IMSS port number, if it is different from the default port 110.
    • To access the POP3 server using a specific port for authentication purposes, click Add to create a new dedicated POP3 connection. Provide the required information and click OK.
  4. Click Save.
