100:115 - 100:130? I wish it were that low.

Probably about 90% of the attempted mail deliveries to my MXer are  
worm traffic. The aggressive heuristics mean that most don't make it  
past MAIL FROM: and probably about 60% of what's left gets as far as  
DATA before also being declined.

I'm considering rebuilding the mail system to gather better  
statistics and be easier to fine-tune.
