Port 25 is open but mail isnt sent

[ankhmor]

I have postfix installed on my computer. I opened my port 25 everywhere possible (or at least I think so). Postfix delivers mail locally and can accept mail.

HOWEVER IT DOESNT SEND MAIL TO OUTBOUND SERVERS.

In the mail.log file it says that connection timed out (port 25).

However when i do telnet localhost 25 I receive Connected to localhost and then 220 anton-desktop ESMTP Postfix (Ubuntu)

What can I do to make my server send mail to outbound servers?

You do not (normally) need to open ports to send mail unless you have explicit deny to all outgoing traffic in you firewall setup, which is kind of unusual.

I had a postfix set up a very long time ago and cannot remember peculiarities but there is an option in the config file to set up the main gateway relay smtp server. If you define it as your ISP's relay it is likely to start sending. It was a solution that worked for me.
