LISTSERV enforces a "Date:" header that should be acceptable to most news
software when you are using FULLHDR, as recommended for gatewaying (it
makes no attempt to check the time zone against the "official" list and
thus it is arguably not 100% guaranteed to be RFC822 compliant).
Unfortunately many list owners insist on using IETFHDR, which operates on
the premise of a SMTP alias; what you send is what you get. LISTSERV does
not do any specific checking for "Message-ID:" since it has no use for
this field.

LISTSERV never uses the "Return-Path:" and will accept postings with
invalid "From:" lines (commands, however, are refused if there is no
valid "From:" line). The problem is when the gateway inserts "Sender:
[log in to unmask]". If you remove this tag the problems will go away.
