[Mailman-Users] no messages being delivered

[Andy Firman]

Install was fine and test list created just fine.  Owner of the list
was notified and that email showed up fine.
All messages going to the list seem to get queued
and they NEVER come out.  This is what I have going on:

Redhat 7.2   Kernel 2.4.18  Python 1.5.2  Mailman 2.0.12  Sendmail 8.11.6

This is from my $prefix/logs/error file:

qrunner(23801):Traceback (innermost last):
qrunner(23801):File "/var/www/html/mailman/cron/qrunner", line 283, in ?
kids = main(lock)
qrunner(23801):File "/var/www/html/mailman/cron/qrunner", line 253, in main
keepqueued = dispose_message(mlist, msg, msgdata)
qrunner(23801):File "/var/www/html/mailman/cron/qrunner", line 157, in
dispose_message mlist.ParseMailCommands(msg)
qrunner(23801):File "/var/www/html/mailman/Mailman/MailCommandHandler.py",
line 123, in ParseMailCommands precedence = msg.get('precedence',
'').lower()
qrunner(23801): AttributeError :  'string' object has no attribute 'lower'

What am I doing wrong?  I am lost.

(please be gentle if its python or sendmail....I know nothing about
python and well...you know.... it's sendmail :-(
