spam / antivirus filtering with LDAP support

[Karolis <list@xxxxxxxxx>]

hi,

I have recently installed qmail-ldap and it is working very fine.

I would like to know whether it would be possible to add spam filter
and virus scanner with LDAP support. The idea is to let users choose
if they want their email scanned or not. In the web interface they
would be able to set their preferences, and mail server should act
according to those preferences.

I have tried searching google, but did not find a lot of info on this
topic. Any help would be much appreciated.

thanks,
Karolis
