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>.
