Well, I'm not fully correct here. You can filter on client addresses with
check_client_access rule, and on sender addresses with check_sender_access.
You can use both in smtpd_sender restrictiona, although I generally use
check_client_access in smtpd_client_restrictions, and check_sender_access in
smtpd_sender_restrictions.
