Hi all,
Having loads of problems with clients complaining about not receiving email from certain domains.
Seems that loads of servers are badly configured and this then causes problems with mine.
Here is an example of a good email but gets rejected because their reverse dns is bad.
Code

I've tried commenting some of the HELO stuff to try and get postfix to accept more of these trouble domains. Can anyone lend a hand to have more relaxed rules?
Here is my /etc/postfix/main.cf
Code
- # SASL parameters
- smtpd_sasl_auth_enable = yes
- smtpd_sasl_security_options = noanonymous
- broken_sasl_auth_clients = yes
- smtpd_sasl_authenticated_header = yes
- smtpd_helo_required = yes
- smtpd_helo_restrictions = permit_mynetworks,
- check_helo_access hash:/etc/postfix/helo_access,
- permit_sasl_authenticated,
- # reject_invalid_helo_hostname,
- # reject_non_fqdn_helo_hostname,
- reject_unauth_pipelining,
- warn_if_reject reject_unknown_hostname,
- permit
- smtpd_sender_restrictions = reject_non_fqdn_sender,
- reject_unknown_sender_domain,
- permit_mynetworks,
- permit_sasl_authenticated
- smtpd_recipient_restrictions = reject_non_fqdn_recipient,
- reject_unknown_recipient_domain,
- permit_mynetworks,
- permit_sasl_authenticated,
- reject_unauth_destination,
- check_client_access hash:/etc/postfix/policyd_whitelist,
- reject_unlisted_recipient,
- check_policy_service inet:127.0.0.1:12525,

- smtpd_data_restrictions = reject_multi_recipient_bounce,
- reject_unauth_pipelining
