Good luck with that. The current sober/mytob strains are mutating rapidly. Be
sure to make your subject rules deal with the variant subjects that use
underscores instead of spaces.

It's really a shame that MS currently only has one "Silent Viruses" option which
pairs with "Still deliver silent viruses".

Unfortunately, in this day and age, anything but "All-Viruses" in the "Silent
Viruses" option is asking for trouble. So you ultimately have the choice of all
or nothing for local user notification.

Yes, the "non forging viruses" offers a way around this, but that also causes
the sender to be notified, not such a good idea for most viruses.

Ideally I'd like to have 3 categories:

	non-forging - notify sender and recipient
	"sender silent" - notify recipient but not sender
	"double Silent" - notify neither (but notify postmaster if enabled)

This way I could list macros as non-forging viruses, list things like the mtob
and sober worms in "double silent" and leave everything else in "sender silent"
so the recipients get warnings about them.
