[Exim] Personal Spamassassin via Exim filters

We currently run spamassassin in our mailhubs along with virus scanning
using exiscan-acl patch. There are drawbacks in a centralised approach
especially with Bayesian filters.

Has anyone used spamassassin via EXIM filters to permit individual
configuraion and personal Bayesian databases.

A copy of your filter would be appreciated and any comments etc.
