I'm sure if you try the following interactive python test, you will see
the same error somewhere, either in the smtplib.SMTP() call or the
Python 2.3.3 (#1, May 7 2004, 10:31:40)
[GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import smtplib
>>> SMTPHOST = 'localhost'
>>> SMTPPORT = 0
>>> x = smtplib.SMTP()
>>> x.connect(SMTPHOST, SMTPPORT)
(220, 'sb7.example.com ESMTP Sendmail 8.12.11/8.12.11; Mon, 16 May 2005
You can see a more complete example that actually sends mail at
You may be able to make this work by changing SMTPHOST to an IP address
or some different name. If so, you can make the same assignment in
mm_cfg.py and Mailman should work.
Otherwise, you have to make whatever system configuration changes are
required to make it work. Possibly the errors returned by the python
library may give you more clues.
