Hello All,

I'm trying to figure out if I have made a mistake in my configuration or I won't match the record for this domain that made it through the rules.

I have the table sender_reject_domain with this record:
mediaware-news.com <http://mediaware-news.com>  REJECT 550 SPR-mediaware-news.com

And below is my configuration:

smtpd_recipient_restrictions =
         permit_mynetworks
         reject_unauth_destination
         reject_non_fqdn_recipient
         check_recipient_access  regexp:/etc/postfix/rcptaccess
          check_sender_access  regexp:/etc/postfix/senderaccess
         check_client_access     hash:/etc/postfix/sender_reject_domain

check_client_access is for checking the client domain name or IP. You probably want check_sender_access to check the MAIL FROM address.


         check_client_access     cidr:/etc/postfix/sender_reject_ip
         check_recipient_access  hash:/etc/postfix/sender_reject_invalid

The header for the message which made it through:

The postfix logs for this message would be far more useful. The logs will show the client IP and verified hostname, and the MAIL FROM name(s) used.
