Good question. Unfortunately, answering it would require that I
remember what project I was working on at a point some 18 months
ago... I don't have the faintest idea. Obviously it happened
somehow. My *guess* would be that it was acquired via
Mail::Message->read and the mail I read in did indeed have neither
field. There's a good chance that I was doing something with a mail
that happened to be 'not strictly valid', but that's depressingly
common with mail. If it had no Received line then it was probably
supplied by the user.

On reflection it would not be unreasonable to croak in this case
(although I'd hope that something more permissive would work, like
using the current time), and I was probably objecting to it 'working'
but spewing an incomprehensible warning - it should either work
cleanly or throw an exception.
