It would not surprise me at all to discover that this is part of
the source of the symptoms I've seen. But note that it still
requires that the -initial- MTA failed to provide a Message-Id:
It's been a while since I read the RFCs; but I thought that the
MTA was -required- to add a Message-Id: if none was present. If
so, this would imply that qmail is not a compliant MTA. (Although,
I can see the argument about that only being the responsibility
of the first MTA to process the message; a counter-argument could
be made that qmail should reject such messages.)
Hmmm. I've just had a quick scan through RFC822, and it lists
Message-Id as an optional field. Unless some other RFC requires
it, it looks like my basic assumption was wrong.
