I just may have to do that. One problem though is that many mails
are encoded in some way (I mean byte-encoding, like base 64) and I
was hoping to make use of the transparent decoding capability of a
class or library made to do that sort of thing. But if I cannot,
then yours is the approach I will probably use.

....but many of them are in commercial packages, or are plugins to
MSExchange or similar. And most of the open-source ones only stick
the footer in the first piece of text/plain that they find, without
being aware of multiparts.

Thanks,

Geoff.
