You didn't mention what your using for your message store, but you might
be able to fake quotas with message_size_limit in your transport, e.g.
message_size_limit = ${someAppropriateExpansion {0}fail}

When the expansion fails due to over-quota, delivery would be deferred.
You might have to use a perl or run expansion. You might also want to
have a script run periodically to deliver an over-quota warning message
(that, obviously, isn't subject to the message_size_limit restriction.

It's not the cleanest solution, but I think it should work.
