The obvious way is by using RCPT acls to defer second and subsequent
recipients. This slows down delivery times for multi-recipient messages and
messes a bit with the queues of the hosts who are sending to you, and could
scale really badly if you regularly get messages with hundreds of
recipients - but it's good for smaller operations where the majority of
messages are for a single recipient anyway.

Tom has a recipe for this in his Exiscan docs -
http://duncanthrax.net/exiscan-acl/exiscan-acl-examples.txt, see section 6,
example a.
