Well, but MOST MTAs I know of, are using the SIZE= extension of
MAIL FROM: and exim sets message_size according to this.
That means we can check the size in the smtp_mail_acl and later, but,
one should not depend on it! So, the best is to make the check in the
mail/rcpt-acl AND in smtp_data_acl. The first two will kick in when the
sending mta send the SIZE-argument, thet data_acl check will do a final
check, for all the others.
