I am not using DMARC.

I am using:

smtpd_recipient_restrictions =
         permit_mynetworks,
         check_client_access cidr:/usr/local/etc/postfix/client_checks,
         check_sender_access hash:/usr/local/etc/postfix/sender_checks,
         check_sender_access hash:/usr/local/etc/postfix/sender_access,
         reject_unknown_sender_domain,
         reject_unknown_reverse_client_hostname,
         reject_unknown_client_hostname,
         reject_invalid_helo_hostname,
         reject_non_fqdn_helo_hostname,
         reject_non_fqdn_hostname,
         reject_non_fqdn_sender,
         reject_non_fqdn_recipient,
         reject_unknown_helo_hostname,
         reject_unknown_reverse_client_hostname,
         reject_unknown_client_hostname,
         reject_unauth_pipelining,
         reject_invalid_hostname,
         reject_unauth_destination,
         reject_unknown_sender_domain,
         reject_unknown_recipient_domain,
         reject_rbl_client zen.spamhaus.org,
         reject_rbl_client psbl.surriel.com,
         permit

Can I add something to make sure that postfix.org emails are not 
rejected?

I don't forward any of my own emails anywhere, I really like to use pine 
email client on the server myself, but this is not for everyone. What is 
funny is everyone asked for webmail, but now that I have it working, 
everyone wants theirs forwarded. I think I am the only one using 
roundcube.

Kind Regards,
Al
