If the "missing" message had a "1969" date when viewed by one
recipient it was likely lacking the "Date:" field/value -- and that
recipient's system put in 1969 as a unix "epoch-1" value. Given that
that's a required field the OP's system may have put it into
junk/spam on the OP's account, or if snarky, refused it. Also, if
that field is missing it's likely that the message is messed up in
some other way that could trigger MSP filtering/refusal. If it was
accepted, looking for it by subject, and in unexpected places, may
turn it up.
