[Email-SIG] Cloning a message

[Nicholas Cole]

I've been scratching my head over this problem (in part thinking about
the PGP/MIME RFC), and although it seems that it ought to have a
trivial solution, I can't work out what it should be.

How do I take all the parts of Message A, and attach them to a new
message object?  I don't want to preserve the email headers
themselves, only the MIME parts.

Best wishes,

Nicholas
