I’ve been trying to open port 25 for postfix, and I can’t figure out what I’m doing wrong. I can’t telnet to the server with port 25, while I can telnet to other, like TeamSpeak3s port (30033). This is what my iptables looks like.

sudo netstat -plutn | grep 25 <br>tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 28291/master <br>tcp 0 0 ::1:25 :::* LISTEN 28291/master <br>
I am trying to open the port for posfix, but the server can’t receive any emails. After a while I get this response on gmail, trying to send an email: <br> <br>Technical details of temporary failure: <br>The recipient server did not accept our requests to connect.

Postfix is listening on the loopback interface. You have to configure it to listen on 0.0.0.0. See <a href=“http://www.cyberciti.biz/faq/postfix-receive-mail-on-specific-network-interfaces/”>http://www.cyberciti.biz/faq/postfix-receive-mail-on-specific-network-interfaces/</a>.
