Spamassassin rules based on IP

[Matt Kettler]

There's no provision in spamassassin for conditionally swapping CF files in or 
out at scan time.

SpamAssassin parses all the .cf files once, and once only when an instance is 
created, and then that pre-parsed ruleset is re-used for all scanning tasks 
until the instance dies.

In order to implement this feature, the rules would have to be re-parsed on a 
per-message basis, and that's not practical for efficiency reasons.

If you have a limited set of rulebases you need, you could create separate 
SpamAssassin instances and call the different instances depending on which set 
you want to use, however this isn't really compatible with MailScanner's model 
of the universe. It's also a massive memory sink in any event.
