That's odd. This google search
<http://www.google.com/search?q=site%3Amail.python.org+inurl%3Amailman-users+%22name+or+service%22>
gets 51 hits, and I'm sure most are relevant.

Searching the FAQ wizard
>Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py
for the simple string

   name or service

finds article 6.14 which is also relevant.

The problem is Python's smtplib can't find your host name or the IP
address for your hostname because it isn't in /etc/hosts or maybe
because of a resolve.conf problem as described in the FAQ.
