Hi David.

Assuming that you want to allow [email protected] to only 
send to [email protected], then you should be able to do 
something like this:

smtpd_recipient_restrictions = check_sender_access inline:{ {[email protected] = check_recipient_access inline:{ {[email protected] = ok } }, reject } }
