Postfix will perform each query.
If the query ends up being the exact same, it will be in your cache.

Prepend the reversed client IP address to the provider's domain
(without =d.d.d.d). See RFC5782 or
or example.com.rbl_domain? Or both or other?
Same for HELO hostname?
hostnames are submitted as host.example.com.rbl.example.com, as per
customary RBL operation.

When using both:
reject_rhsbl_client rbl_domain=d.d.d.d
reject_rhsbl_helo rbl_domain=d.d.d.d
If the PTR and HELO are the same hostname like
then reject_rhsbl_reverse_client would
never get used?
-
In the manual maps_rbl_reject_code references:
reject_rbl_client, reject_rhsbl_client, reject_rhsbl_reverse_client,
reject_rhsbl_sender and reject_rhsbl_recipient restrictions.
reject_rhsbl_helo is not listed. Does rbl reject code
Thanks! With reject_unlisted_recipient it indeed works as desired!
