Here you get a different Traceback than in the original post.

After digging in smtplib.py here ( Python 2.3.3 )

the call should be socket.getaddrinfo( "smtp.mail.yahoo.com", 25, 0, socket.SOCK_STREAM );

which succeeds here at my installation.

How do you resolve your hostnames ( /etc/nsswitch.conf gives the order of hostname resolution )

This should resolve your own local hostname!
The socket.gethostbyname() is a call into a shared object of Python and this would use
( So think I ) the standard-Libraries for resolution.

Is "linux" a valid hostname?
Does "ping linux" succeed.

I still think, that this a name resolution error on your host.
