The right hand side of the 'spam=' line is expanded, so you can use
expansion variables and so on to select which SA user profile to use -
perhaps based on something that happened in a RCPT acl....

Having said that, this is not a particularly elegant way of doing
per-user profiles. I, and many others, make do with a single profile
and process the SA score per-recipient instead. Still not perfect, and
relies on one-recipient-per-message or
one-spam-scan-profile-per-message, but it does keep all the admin in
the Exim realm rather than having to maintain separate profiles in SA.
And you lose per-recipient Bayesian capabilities.
