Not inside Mailman.
A solution that does not require modifying Mailman code is to put the
size restrictions in the MTA's configuration instead. Most MTA's support
global message size limits so if you can live with one limit for all
lists and all other addresses served by your MTA, you can just set that
global limit as a fix. If you need more granularity, many mail filtering
tools that act as adjuncts to an MTA (e.g. amavisd-new, mimedefang,
etc.) can enforce recipient-specific message size limits before messages
are accepted by the MTA. If you are already doing strong spam filtering
there is a good chance that you have the tools you need in place,
although it may take some work to implement a solution.
