SMTP Proxy relaying to a different port

Dr_Jones over 18 years ago

Hi there, Our smtp proxy listens for outside traffic on port 25, but our internal smtp server listens on port 125. Is there a way to configure Astaro to relay on a different port other than 25 internally?

Thanks

TCP port 25 is the standard for SMTP mail transfers.
What about using the KISS approach?
Simply change your mail server back to using port 25 instead of 125 for its SMTP connections.
