Symptoms
Error: "Invalid SMTP port number supplied. Try again." appears during installation of Symantec AntiVirus for SMTP Gateways 3.x and Symantec AntiSpam for SMTP 3.x The error: "Invalid SMTP port number supplied.

Solution



If port 25 is not available during the installation of the Symantec product, it can indicate the existence of another SMTP server on the computer. Because the Symantec product is an SMTP server, it must have exclusive access to the TCP/IP port (port 25) that corresponds to that service. You must disable these conflicting services before the installation of the Symantec product.

Other options
  • Install AV for SMTP to a different server.
  • Disable the existing SMTP server program.
  • Change the existing SMTP server program to use a different port (a port greater than 1024). Please consult the existing SMTP server's documentation for help on changing the port. When the computer is not a mail server go to the Technical Information section for steps on changing the port.

  3. In the dropdown for Startup Type: click Manual.
