enabling alternate smtp ports

Port 25 being blocked..have tried following instructions re:enabling submission to activate port 587 and 465, but I still can't sent through these ports. I can connect to port 587 with telnet

Can you suggest way forward?

Howdy -- if you're able to telnet to port 587, that's a good start!

What error(s) do you get when trying to send an email via port 587?

Do any error messages show up in your mail log, /var/log/maillog?

Also, note that port 587 uses SSL/TLS encryption -- and that your email client would need to be configured to use that when communicating on port 587.

thanks for the response. Enabled SSL and enabled postfix to use cert

All working

Great, I'm glad it's working now!
