Hi all How could I apply those rules to my postfix on a debian5 in the main.cf: 1: Reject unauthentificated Mail senders (Mail from) 2: Reject senders without reverse dns entries (Mail from) 3: Reject mails wich are not authentificated from customers Thanks a lot admins
Code: smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination reject_unknown_recipient_domain reject_unknown_sender_domain reject_unverified_recipient reject_non_fqdn_recipient reject_non_fqdn_sender reject_invalid_hostname Look at the postfix docs to see what these options mean
