Yes, I understand what you're asking for and that's not something
that's supported. NSS has a more complete facility for this sort of
thing using a Berkeley db of certs, but iirc that's only used by
firefox and isn't actually supported by tools like thunderbird. I
think this is basically an area where there's no real support at all
under linux (and to be honest isn't something most users need or have
the ability to configure).
