It would be nice to do this from the UI.  You can't expect people to use a 
command line tool.

I know what its intentions are, but Netscape 4.7 didn't import the 
certificates contained within such a message (as far as I can recall).

Besides, I was just responding to a question of what formats should be 
supported for import/export.  I merely raised the point of whether a PKCS#7 
certs-only message was worth it, given that some mail clients do not 
support it, and it offers no additional benefits over a signed only 
message.

PKCS#12 is already supported, hence I didn't raise it. :)
