Well, my current stats say:

	User unknown:           25 %
	RBL-blocked:            32 %
	keyword blocked:         1 %
	other blocked:          24 %
	locally delivered:      17 %

So a "cut down to 99.9%" is a bit pessimistic (filtering only 0.1% out)
- if you meant "cut by 99.9%" too optimistic. But cutting off 82% even
before the DATA command is not too shabby. OTOH it is a sign on how bad
mail has become if more than 80% are plain junk even without looking at
the content.

Bye
