OK. You found
if bodylen/1024.0 > mlist.max_message_size:
hold_for_approval(mlist, msg, msgdata,
MessageTooBig(bodylen,
mlist.max_message_size))
All you have to do is change it to
if bodylen/1024.0 > mlist.max_message_size:
rej_msg = 'Message too big: limit = %d KB' %
mlist.max_message_size
raise Errors.RejectMessage, rej_msg
Watch out for wrapped lines in both of the above code fragments. Of
course, you can make rej_msg anything you want.

Each incoming message is passed through a pipeline of handlers (defined
in Defaults.py as GLOBAL_PIPELINE). This continues until the pipeline
is exhausted or an exception is raised. To reject a message, raise
Errors.RejectMessage with an appropriate reject notice. To discard a
message, raise Errors.DiscardMessage, although if you want to honor
the list's forward_auto_discards setting, call Moderate.do_discard().
Holding is more complicated because of the various possible
notifications and other things that need to be done, so normally you
call Hold.hold_for_approval().
Descisions are distributed through various handlers because we want to
modularize the various functions like spam detection, membership tests
and miscellaneous holds, yet at least spam detection and membership
tests can hold, reject or discard a message based on list settings.
