Unfortunately, the manual is incorrect about when the expansion happens.
In fact, it happens at the start of the connection, not for every
message. The limit can therefore depend on the client host, but not on
the sender.
I should either mend the manual or the code. Problem noted. Of course,
even expanding for every message might happen before the sender is
known, but it probably should be after.

Your only choice at the moment is to put a test of the $message_size
variable into the DATA ACL.
