I can't send any email with Postfix

Posted February 7, 2015 1.4k views

Hi there,

Postfix couldn’t be accessed from the outside (not localhost). Here is my netstat:
tcp 0 0* LISTEN 17841/master

tcp6 0 0 :::110 :::* LISTEN 15585/couriertcpd
tcp6 0 0 :::143 :::* LISTEN 15547/couriertcpd

Ports 110, 22, 21, 80, 53 works are open. But not 25. What’s a problem?

I think port 25 is close on most DO droplets, or so I read on past questions, so you need to contact support.

Better yet, try zohomail or google apps (zoho is free for up to 10 users).
