Per-user capabilities

[Khalid Waheed]

SpamAssassin has all sorts of per-user capabilities, including whitelists, rule 
weights, and Bayesian filtering.
But all of this stuff is totally useless in some mail servers (e.g. SunOne 
messaging server), for the simple reason that being able to process mail for 
multiple users simultaneously is an absolutely critical capability, and 
SpamAssassin is simply not designed to offer this capability.
