Milter-greylist

Since my previous message to the list this morning has apparently been  
lost somewhere, yes:

root@mx ~]# grep -c "delayed for" /var/log/maillog
23231
[root@mx ~]# grep -c "autowhitelisted" /var/log/maillog
658

... and that's just today. Bot farms generally don't retry, dedicated  
spam relays do. I've manually blocked a few overseas /24s due to this,  
but otherwise, I let it run by itself.

Make sure you're looking for the right data.
