smtp

I have a few questions, I just installed SMTP on my Ubuntu server, and I want to know how to connect to it from a different machine... I'm not really clear.

I tried:

telnet my.servers.ip.address 25

I think it's running on port 25, but I don't know where to find out, its not in the conf file anywhere.

Additionally do I need it to be a FDQN? or can I just access my mail server via it's IP address? I know that the service works on the machine because I'm able to

echo test | mail -s "test" [email protected]

Any help debugging or understanding this would be helpful, thanks guys!
