Send email to SMTP server on non-standard port.

Question

How can I email to a domain whose SMTP server does not listen on the standard port 25? I need to email to it through webmail, like GMail.

I thought this would work: [email protected]:port

Answer 1

You can't do it with gmail. You need to configure a mail server to do this, and it's hard. The only other option is using a firewall to redirect traffic from 25 to your port.

(And this probably belongs on serverfault).
