rejected. I am *not* resending it, since Mark quoted everything at
some point. Nobody except me lost mail, and I deserved to! :-]

Absent a bug in the email package. But yes, I'm suggesting exactly
that there's a broken MUA out there sending something that doesn't
parse correctly, and the email package is failing to respect the "In
the face of ambiguity, refuse to guess" Zen.
We really need to see both the input and the output headers that
Mailman sends and receives.
