We have tested mimedefang, a milter filter for sendmail (which has
DCC/Razor/Spamassassin/Anti Virus plugins etc) and it works really well
finding most Spam (TAG's info in the header). Scales very well for usage.
Alot more customiseable/less load than alot of commercial packages out there
at the moment and all open source software.
Thanks

It is possible to set SpamAssassin up so that users can control their own spam filters. This does require a reasonable amount of coding to get it to work.
I believe that Steve Phillips was working on something like this a while ago. Getting something like that working in conjunction with RBL queries on a per-user level would be great for allowing the customers more control over their mailbox.
