Running SA from a system filter, even indirectly, is likely to be a
practice best kept for the seriously masochistic :-)
If you run SA from a router (director in exim3), then add to the
condition you have on that router/director a lookup for the recipient in
a list of potential victims, or do something like make it conditional on
the existence of a particular file in the users home directory (look at
the condition and requires directives).
If you run SA from something like exiscan then modify the
exiscan_spamd_condition appropriately - this might be slightly more
difficult since you may not have a single recipient defined at this
stage, but you should be able to work round it....
Personally I would tend to scan *everything* and then make per-person
decisions later down the routing tree dependent on the outcome.

Yeah - thats about it.
exiscan looks well worth trying (I have it running here now) - the MIME
file extension handling is useful in these days of Bugbear etc, without
running a real virus checker.
