Hi all, i'm trying to reduce the spam accepted by the server adding some options to main.cf in postfix configuration. I added Code: smtpd_helo_restrictions = reject_non_fqdn_hostname, reject_invalid_hostname, permit_mynetworks and modified Code: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unknown_sender_domain, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf in /etc/postfix/main.cf tryng to reject all mails from not fqdn HELO senders, but with no results. in mail.log i can see a lot of warnings like Code: warning: hostname mail.neuronetsys.com does not resolve to address 103.20.168.21 but no mails are rejects. Any clue ?
