Ahh, yes.  Well I would suggest that it is PostFix (which is handling the
outgoing mail for the LISTSERV server) which is broken here.  It should not be
looking at any RFC822 headers at all to determine where to report errors.
RFC821 provides very good instructions on what to do and as an MTA that is all
that PostFix should be doing.
