[Mailman-Users] Discard message and forward message to third party failed

[mailman-users at comp-u-port.net]

Background:
-----------
Mailman v2.0
RedHat Linux 5.2
Python v1.5.2
Sendmail 8.9.3

(Yes, this machines needs some serious upgrading, but then it is only
a 486/66! :)


Problem:
--------

We had a post to a closed list that went into the pending queue.
List Admin wanted to discard the message, but forward it to a third
party, too.  They marked the discard radio button, checked the
"Additionally, forward..." check box, and entered the address to
forward the message to.  Cool, just want we want.

They submitted the web page, but never received the message.  :(

Looking at the sendmail logs it shows that the list admin fat fingered
the forward to address such that address had an invalid domain.  (i.e.
properaddress at .domain.name - notice the extra dot.)

sendmail logs shows two lines:

WAA32533: <properaddress at .domain.name>... Invalid host name
WAA32533: from=<mailing-list-admin at lists.domain.name>, size=4430,
class=0, pri=0, nrcpts=0, proto=ESMTP, relay=IDENT:mailman at localhost [127.0.0.1]

Now the problem.  The forwarded message has disappeared!  It is not in
the list admins, site admin, mailman, or postmaster's mailbox.  Nor,
is it in the mail queue.

The Mailman logs show the message being discarded (in logs/vette)
and being handed of to smtp in logs/smtp, but nothing in
logs/smtp-failure.

Since I don't know what the forwarded message headers looked like, I
can not tell if this is a sendmail or mailman issue.  Does anybody
have any ideas?  Shouldn't the return-path of the message have been
the list-admin address?  Shouldn't sendmail as the last resort drop
the message into postmaster's mailbox?

Is this a bug in sendmail or Mailman?
