I see in my firewall telenet/25 is blocked. However smtp/25 is allowed.
What does that mean? Both services use TCP. Telnet is normally port 23, SMTP is 25. I suggested 'telnet IP_address 25' as a quick way to see if tcp/25 is permiited.
I can't connect now, though, so either postfix is not listening or there is a firewall somewhere.
