It looks like two messages get logged by sendmail for a given email:

Feb  5 10:55:46 mail2 sm-mta[49256]: h15Itjct049253:
to="|/local/mailman/mail/ma
ilman post listname", ctladdr=<listname at domain.com> (26/0), delay=00:00:01,
xdelay=00:00:00, mailer=prog, pri=30914, dsn=2.0.0, stat=Sent

Followed by:

Feb  5 10:55:47 mail2 sm-mta[49261]: h15Itlct049261:
from=<listname-bounces at domain.com>, size=1694, class=-30, nrcpts=10,
msgid=<BCFA1D35-393B-11D7-AA7A-0003
9300CAE4 at domain.com>, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1]

In that same time-frame, the following message appears in Mailman's "post"
log:

Feb 05 10:55:48 2003 (41415) post to listname from listname-bounces at domain.c
om, size=1694, success

So, before Mailman posts the message to the list, it's already rewritten the
header of the message to appear to be from the "-bounces" address.

Does that shed any light on the issue?

Thanks,

Tom
