"deny" using an ACL which reads $message_body_size.

You might also like to use a router which redirects to :fail: with an
appropriate message.

Firstly, I suggest you negate that - have the condition check that the body
only contains allowable characters. Secondly, your condition will be more
readable if you use [...] in the regex instead of (...|...|...).
For example, something based on:
${if match{$message_body}{\N\A[A-Za-z0-9 ,.-]\z\N} ...}
but you'll probably want to allow more characters than that, and maybe you'll
also want to automatically fold NL/CR/TAB to spaces. In which case, look for
"${sg" in the documentation.

And, let me guess, should contain only 0-9 ?
Add something like "local_parts = \N^[0-9]{1,10}$\N" to your router.
All untested. Testing, and fixing my errors, I leave as an exercise for you.
