What is the reason to " Connection time out" whit Postfix??
Hello, I am using Postfix in a OpenSuse box fresh install. This linux is a backup for my domain (NS and MX). When I try to use this Postfix to send messages I always receive a Conection timed out.
I attached the mail log. Thanks for any help.

I suspect it's not postfix problem anyhow.
try: telnet yahoo.com 25 # any luck?
Now, verify if Your server's IP is blacklisted on some of those (in)famous dnsbl.
Start from http://www.kloth.net/services/dnsbl.php , google others

Exactly, this is the solution. Once i set "disable_dns_lookups" to "no" everything is working fine.
More info uust for help to others. My server is behind a router and my postfix is a MX backup for my domain.
The "disable_dns_lookups" directive must be set to yes only if you are using other server to send messages.
Thanks.
