[Mimedefang] per-user filtering

[Aaron Paetznick]

Has anybody come up with an efficient method of managing filter 
preferences on a per-user/address basis?  I could "hard-code" user 
preferences in the mimedefang-filter file, but I want to give my users 
the ability to change their preferences on the fly via a web page.  I'm 
thinking either a SQL table or DBM file would be best.

Idealy, I'd want MIMEdefang to "mask" the user's specific filter rules 
onto a default global set at a very early stage in the filtering 
process.  They would then be able to choose whether they wanted to use 
SpamAssassin, Vipul's Razor, File::Scan, etc. and set rules for each 
(whitelist, blacklist, etc.).  This would of course be expensive from a 
system resource point of view, but I would think that if it was done 
right, the performance hit could be managable.

Has anybody coded anything that even aproaches this kind of functionality?

Thanks.
