I've been setting up a generic mail server with OpenSuSE 10.0 and noticed something weird. My netstat displayed port 25 listening, but.. its listening on the loopback.
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
To my understand, having the 127.0.0.1:25 instead of 0.0.0.0* prevents me from telnet to that port, causing problems with receiving email.
How do I change the 127.0.0.1:25 to the 0.0.0.0*?
Any help is appreicated.
