It's much better to reject spam. Do all you can in Exim ACLs to reject mail
from RBL listed sites, and so on. Configure Spamassassin to run from an
ACL.

Marking up spam doesn't seem very sensible to me, as users that get lots of
spam are likely to delete it without examining it anyway. Much better to
reject everything that you can - then false positives will be notified to
the sender.
