Mailman - Sendmail problem

[swangdb]

I have a Sun Server running Solaris 10 and Sendmail 8.13.7.  I have
Majordomo and Listproc installed on this server and they work.  I have
several production majordomo and listproc mailing lists installed on
this server and they work.

I am trying to get Mailman to work on this server and so far, no luck.
I installed the software (Mailman 2.1.8 and Python 2.4.3), reconfigured
mm_cfg.py, started the software, added the cron entries, created a test
mailing list, added the list information to /etc/aliases, ran
newaliases and subscribed myself.  When I send a message to the list,
it doesn't send me a copy of the message (I am the only subscriber to
the list).  If I look on the list's web site, the message I sent is
contained in the archives.

In the Mailman error log, I get messages similar to the following when
I send a message to the mailing list:
***

***

It's funny, Sendmail.py is included with the program source, but the
documentation says that "Use of the Sendmail.py delivery module is
highly discouraged."  Is it possible to use Mailman with sendmail
without using Sendmail.py?  I'd like to use sendmail if possible.

Thanks for any help you can give!
