Message with no From header at all, sent simultaneously to Paul Hoffman and
the ietf-822 list, for the purpose of investigating the imc majordomo.
Yes, imc runs sendmail, which has inserted its own From header based on
the envelope From, wgich defeates the intent of the test.
So I shall try again with MAIL FROM:<> (I think sendmail will leave that
So we have so far established that "From: <>" gets through to most people
(except Bruce, who claims he never received his) but we need more evidence
as to what systems allow completely absent Froms to pass through
