It sounds like a better approach would be to make Dovecot reject any email no matter what the size is (even size=0) if a user is over quota. I'll take further discussion to the dovecot mailing list then.
If you are not aware, dovecot has by default a 10% over quota grace. So even being a couple of bytes over quota it would still accept a small message.
