You should evaluate each recipient quota at smtp time, and reject
individual recipients. Unfortunately Exim does not make this easy;
what I do is inspect the maildirsize file (plus a DB flag) in the rcpt acl.
But I have to trust the sender's claimed message size, until data-acl time.
Hence the DB flag, which can mark them as already over-quota
(and be seen by secondary-MX systems).
