You have a choice:-
  - you run SA once on each message and do not have the option
    of applying recipient specific rules
    + either at SMTP time (reject early) - sa-exim local_scan patches
    + or during routing - config change only to exim
  - You run SA once per recipient delivery at the cost of more
    SA invocations, lower efficiency, but more customability

To do the latter run it as a filter to final delivery (no choices then
as to final disposition - unless you are delivering via something like
procmail), or explicitly have each user run it from procmail (or within
your system procmailrc).

You can't bounce stuff properly* if you scan per user, if you scan once
per message you can do some degree of bouncing, but you need to be
scanning in local_scan to reject at SMTP time (however for broken SMTP
implementation on the sender side this can have downsides such as the
sender attempting to resend again and again).

*Note You can error exit from your final delivery process which will
cause some level of bounce.
