You are doing Sender Address Verification (reject_unverified_sender)
before doing RBL checks. Fix this. Do the RBL checks first, and consider
not doing SAV at all, but if you do use it, do SAV *last*.
smtpd_client_restrictions =
... no reject_unverified_sender ...
smtpd_helo_restrictions =
... no reject_unverified_sender ...
smtpd_sender_restrictions =
... no reject_unverified_sender ...
smtpd_recipient_restrictions =
permit_mynetworks,
reject_unauth_destination,
reject_rbl_client zen.spamhaus.org
... no reject_unverified_sender ...
smtpd_data_restrictions =
reject_unverified_sender
