Hi,
How to allow a domain in EFA who have no PTR record. I don’t want to remove postfix restriction for PTR record. Actually I want to exclude some domain for postfix PTR restriction.
Thanks in advance.

Re: client host rejected: cannot find your reverse hostname
That's a good postfix question. I believe this is possible, but I am unsure of the exact steps to take.

Re: client host rejected: cannot find your reverse hostname
After doing some search and research, I found a way to exclude some IP for PTR restriction –
# postmap /etc/postfix/client_access
# service postfix reload
Code: Select all
# vi /etc/postfix/ client_access
1.2.x.x OK
3.4.x.x OK
Code: Select all
# vi /etc/postfix/main.cf
smtpd_client_restrictions = permit_sasl_authenticated, reject_rbl_client zen.spamhaus.org, check_client_access hash:/etc/postfix/client_access, reject_unknown_reverse_client_hostname
# service postfix reload
