Well, I'm a prof mailadmin who happens to have been forced into the 
Postfix shoe (latest version of everything with me) and am feeling very 

I have a perfect pdf spam solution, I refuse all mail that isn't for my 
users, my 1550+ user site currently refuses far more mail than it is 
offered, we don't get any false positives, none of our users complains 
about lost or delayed mail.

But I'm not going even to *begin* to explain how, to anyone (only to 
die-hard Postfix people, but they taught me how, anyway). Yet less when 
a novice yuks. The only answer is: "Learn to be a mailadmin", and that 
take years, believe me.
