[Tutor] SMTP('my.smtpserver.com') hangs

[Leam Hall]

Python 2.6.6 on CentOS 6

I'm in section 3.4.12 of Wesley Chun's "Core Python Applications 
Programming". The POP3 stuff works but I can't seem to get the SMTP to 
connect, it just hangs and then times out. Running it in IDLE gets the 
same thing. Have also tried with the port # set, as well.

Thoughts?
