== 4.72. How do I configure Mailman to use an external SMTP server? ==

In mm_cfg.py add or modify:

{{{
DELIVERY_MODULE = 'SMTPDirect'

SMTPHOST = 'mail.example.com'
}}}


If the external server uses a different port than the default, also:

{{{
SMTPPORT = 1234
}}}


If the external server requires userid/password authentication to relay mail, see <[[http://mail.python.org/pipermail/mailman-users/2005-October/047086.html|http://mail.python.org/pipermail/mailman-users/2005-October/047086.html]]>.
