Not sure, but please try this at the interactive prompt and report
(or analyze) what it returns:

 >>> from socket import *
 >>> getaddrinfo('', 25, 0, SOCK_STREAM)

This is something that is actually doing to get the
host:port combination that it uses to connect.  It seems that
the only possible source for the failure you see is if it
does not return the expected values.
