Summary: Empty Bounces

Initial Comment:
I have a mailing list, X managed by Mailman 2.1.9 on FreeBSD 5.3 with Courier as our MTA. 

All the member addresses of X are valid. The owner address is also valid. We allow non-member postings as well. 

Every time we send an e-mail to the list, we get an e-mail with no subject, and no body from mailman-bounces.  If I turn on Uncaught bounce notification, the message that is forwarded has no contents.

The logs show:
Aug 21 11:01:12 2007 (1493) bounce message w/no discernable addresses: None
Aug 21 11:01:12 2007 (1493) forwarding unrecognized, message-id: n/a
Aug 21 11:01:12 2007 (1493) bounce message w/no discernable addresses: None
Aug 21 11:01:12 2007 (1493) forwarding unrecognized, message-id: n/a


... I'm not quite sure what is going on, but I am fairly certain that this is a bug.

To answer your questions (apparently I can't quote your message, my
apologies)

1. No auto responders are in use. I will attempt to sanitize and post up
some courier logs for you tomorrow.
2. While I haven't gone as far as to capture individual messages in
transit, the attached "messages" are completely empty, yes. 

With consideration to one, I'll try to enable some kind of tracing on the
programs as they are executed when I get into work...

Maybe, but not necessarily.

What do your Courier logs show?

It is even possible that one of your list members has a misconfigured
autoresponder of some kind.

In any case, Mailman is receiving this empty bounce message, and something
(presumably outside Mailman) is sending it.

What are the headers of this message, or are there no headers either?
