We've seen this since 1.8e was installed. Has anyone else seen it?

Bounce message comes back to the owner-listname address. Instead of
forwarding to the list owner, the message is sent back out to the list
address with two "From" headers -- one from the postmaster at the site with
the bad address and one from the original author of the message. Since that
one is second, the "postmaster" address is ignored and the message goes out
to the list.

We've been able to block the behavior with a content filter -- but that's a
tad annoying.

It seems to only affect bounce messages that come in a multipart MIME
envelope with the original message included as type "message/rfc822".
