Some hints to reduce spam and such by significant numbers:
 - Check domain validity (simple check will save about 20%)
 - Use call back (more complex check kills about 80 to 90% of all bogus
messages)
 - Add central virus and spam filtering.

To get a grasp of home usage figure see
http://hvdkooij.xs4all.nl/cgi-bin/mailgraph.cgi which I started to record
just after the first hype of the current saga of Mydoom variants and other
unfriendlies.

During breakouts I kill about 90 to 95% of all messages as they fail on
simple checks.
