The size of attachments is not checked. The size of the entire message
is checked in Mailman/Handlers/Hold.py.

Mailman/Handlers/MimeDel.py is the handler that processes the Content
filtering options.

You could expand the user's options to include a flag for whether or
not to apply content filtering for this user, but implementing this
would be tricky in the current Mailman architecture as it would
require the list to effectively be personalized and then the content
filtering to be applied for each recipient at delivery time instead of
generally in the pipeline of incoming handlers.

You could just set Non-digest options->scrub_nondigest to Yes which
will cause all non-plain text attachments to be removed and replaced
by links. I the list's archive is private, the user's will need their
list password to access these attachments. It seems this might do what
you want with no code changes at all.
