Porn msg identification?

Hi Rich,

The point is that MailScanner doesn't know anything about scoring messages... 
the spam score you see in MailScanner is actually done by the SpamAssassin 
library that MailScanner optionally uses.

Now, _that_ library, including the rules that come with it, is developed and 
optimized to tag as much spam as possible _avoiding_ as many false positives 
as it can.

Thus, SpamAssassin scans the message looking for patterns and it adds or 
substracts from the score as some conditions are met or not...

You _could_ create a different set of rules for SpamAssassin and invoke it 
twice, once for spam detection and the other for "adulthood" detection, but 
that would imply at least modifying MailScanner and using a secondary set of 
SpamAssassin rules... it _will_ require some time and an effort to do it...
