It can be done, but given exiscans "early" operation point it is not
very straightforward. There are several ways to do it. Nico Erfurt has
proposed the nicest one (so far):

Well, the best thing I could think of is to set a header at RCPT-Time,
like this.
warn message = X-Do-Exiscan: 1
domains = list : of : domains
and just use $h_x-do-exiscan: in your condition.
So the message will be scanned once, if a "to scan"-recipient is listed.
You should remove all Exiscan-headers for "no scan"-recipients in your
transports.
--------------------------------------------------------------------
You can then use the "pass" action and drop mails at routing/transport
time when the X-Infected header is set. You cannot use "reject" since it
is not possible to selectively reject messages per-recipient at that point.
Oh yeah, and you can't have your cake and eat it, too :)
