I added the following to main.cf smtpd_recipient_restrictions = reject_invalid_hostname, reject_non_fqdn_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 zombie.dnsbl.sorbs.net, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client list.dsbl.org, reject_rbl_client sbl.spamhaus.org, reject_rhsbl_sender dsn.rfc-ignorant.org permit I reload (postfix reload) and re-started postfix (/etc/inint.d/postfix reload), but the output of postconf -d smtpd_client_restrictions smtpd_helo_restrictions smtpd_sender_restrictions smtpd_delay_reject smtpd_recipient_restrictions is still smtpd_client_restrictions = smtpd_helo_restrictions = smtpd_sender_restrictions = smtpd_delay_reject = yes smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination what am I doing wrong? I added these lines to the end of main.cf THanks for your help
Did you add it like this... (without whitespace) Code: smtpd_recipient_restrictions = reject_invalid_hostname, reject_non_fqdn_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 zombie.dnsbl.sorbs.net, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client list.dsbl.org, reject_rbl_client sbl.spamhaus.org, reject_rhsbl_sender dsn.rfc-ignorant.org permit ... or like this (with whitespace)? Code: smtpd_recipient_restrictions = reject_invalid_hostname, reject_non_fqdn_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 zombie.dnsbl.sorbs.net, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client list.dsbl.org, reject_rbl_client sbl.spamhaus.org, reject_rhsbl_sender dsn.rfc-ignorant.org permit You need whitespace in the lines following smtpd_recipient_restrictions = because otherwise Postfix doesn't know the lines belong to the smtpd_recipient_restrictions directive.
With white space. Anyhow, I had to stop working on the server for a few days. Will start again tonight. Hope I'll get it working
