How do I set up SMTP on port 587

  • Posted January 30, 2015

I am using POSTFIX and Dovecot and have the incoming email working OK. Also outgoing via mail or sendmail works OK. But I can’t seem to get Thunderbird on my home computer to connect with the server on port 587 (or 25 for that matter). I have tried telnet and also did an nmap which showed these ports open: Discovered open port 80/tcp on 107.170.244.155 Discovered open port 143/tcp on 107.170.244.155 Discovered open port 8080/tcp on 107.170.244.155 Discovered open port 995/tcp on 107.170.244.155 Discovered open port 993/tcp on 107.170.244.155 Discovered open port 110/tcp on 107.170.244.155 Discovered open port 22/tcp on 107.170.244.155

Gut no 587 or 25. What am I missing?

Since neither is open, I’m going to take a stab in the dark and say postfix isn’t running.

service postfix start
