Nothing in postfix that can do that by itself.

How about putting all mail on hold and running a script that releases
mail smaller than the target size?
# main.cf
# put all smtp mail on hold
smtpd_sender_restrictions =
   static:hold

Sorry, don't have a sample 'release if less than 15M' script handy,
but you could do this by either parsing the output of mailq or by
searching the "hold" queue directory.
