See the FAQ at <http://wiki.list.org/x/RoA9>.

What does the sender look like in the archived messages?

The reason is no address can be parsed from the message. It has nothing
to do with whether or not the address is that of a list member.

This could be something broken in Mailman (not likely related to the
From: issue), or it could be some new bounce format not currently

Please send me a copy of the raw unrecognized bounce attachment and tell
me what Mailman version this is.

Also, if the FAQ linked above doesn't explain the From: issue, send me a
copy of a complete, raw message received from the list.
