It looks like below here up to my next comment are the actual bounce
notice headers with Return-Path: <> indicating a null envelope from
which should be the case for a normal bounce.

The headers above here look like Mailman received this bounce and
resent it to a list owner. When sending to a list owner, Mailman sets
the envelope from the site list (mailman) -bounces address. Is
[WRONGDOMAIN.COM] the domain of the site list?

And the header below may have also been added by Mailman in resending.

The thing that's strange in all the above is that Mailman (at least
standard GNU Mailman) doesn't redirect bounces like this. It sends a
totally new message to the list owner with the original bounce
attached.

Also, assuming [BADEMAIL ADDRESS]: in the notice was enclosed in <> as
in <bad at example.com>:, it would not have been an unrecognized bounce
in 2.1.9.

Is this Mailman 2.1.9 installed from our distribution, or is it a Plesk
or other package?
