I don't think it's so much their problem, as it is a general limitation 
of SMTP-time rejection.  Since a single message could be intended for 
multiple recipients (and thus multiple domains), you can't really do any 
type of per-user (and by extension, per-domain) settings during the SMTP 
session.  Once you've hit the DATA phase, a reject is all or nothing.

Any type of SMTP-time SA scan is going to have similiar limitations 
(Exiscan-ACL, SA-Exim, Amavisd-new and Postfix in certain configurations).
