I'm not sure where you're looking?

Certainly there is a variable with the detected max line length of
a message being handled; you can code ACL to check it and reject
the message if you regard it as overlarge.

... nor what you mean by "forced in the code", given that
the smtp transport has an option, which you can set in your
configuration, and will be used for outgoing mails sent by that
transport.

Both ACL and transport options are part of your configuration.
