There speaks/writes a bitter man. I'm a Postfix (Unix/Linux) mailadmin; 
my  (always latest stable) Postfix MTAs consequently refuse mail for 
non-existent users and do much anti-UCE stuff in addition. We refuse 
almost as much shoot stuff as we accept genuine stuff.

I've always wondered why so many Postfix sites are there (from the 
Postfix mailing list) simply as front ends for Microsoft Exchange MTAs. 
Well, now I have a better understanding.
