A down the road idea ...
Is there currently a place in GroupServer's webadmin to define file types to
ignore/discard? If there was I'd add VCF to the list, since the value of
that attachment is dubious for ongoing group exchanges.

Yes there are plans to deal to vcard attachments, but it would be better to do
something smart with them, rather than just blocking them based on the
mime-type. My idea from January was to parse the vcard, probably using the
"vobject" library
http://pypi.python.org/pypi/vobject/
and only discard the attachment if the information is for the same person that
posted the message. Otherwise you could not post the vcard for anyone else to
the group!
I would also like to do some smart-processing of PGP signatures, and the silly
markup language that Apple Mail uses. However, it is all far down the track.
