You can use acl_smtp_data, which is called once the mail has been
received into the queue, but before the server responds to acknowledge
message receipt (and so, before delivery begins). In this case, you
will have the real size.

You can also reject predata based on size, but you're then going based
on whatever size was advertised by the client in the MAIL FROM line,
which isn't necessarily the same as the final real size.
