I tried to implement RBL and postfwd. I placed everything in main.cf:
smtpd_recipient_restrictions =
check_policy_service inet:127.0.0.1:10040
reject_invalid_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_unauth_pipelining,
permit_mynetworks,
reject_unauth_destination,
reject_rbl_client bl.spamcop.net
permit
That worked, but it affected both the smtp and submission ports. I expected
that, but it made it easier to test. However, I then needed to make the
submission port work properly. So I made the following change to master.cf and
removed those lines from main.cf:
smtpd pass - - n - - smtpd
-o smtpd_recipient_restrictions =
check_policy_service inet:127.0.0.1:10040
reject_invalid_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_unauth_pipelining,
permit_mynetworks,
reject_unauth_destination,
reject_rbl_client bl.spamcop.net
permit
After a postfix reload basically everything stopped working. There were no
errors reported in maillog. Basically, nothing was going into maillog. So I
went back to the original configuration and it started working again. I then
added the following to master.cf to remove those from submission port:
submission inet n - n - - smtpd
-o smtpd_recipient_restrictions=permit_mynetworks
This approach works, but it seems to me that the first approach should have
worked. Apparently I have formatted the options incorrectly. What did I do
wrong?
