Greetings. I'm trying to adjust my smtpd_recipient_restrictions so that any emails coming to a non-existent account on my server would be rejected BEFORE the attempt reaches RBLs/RBL queries.
Thus, before I activate my settings, I wanted to ask for your opinions, so here how it goes; smtpd_recipient_restrictions = reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, reject_unlisted_recipient, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client zen.spamhaus.org=127.0.0.[2..11], reject_rhsbl_sender dbl.spamhaus.org=127.0.1.[2..99], reject_rhsbl_helo dbl.spamhaus.org=127.0.1.[2..99], reject_rhsbl_reverse_client dbl.spamhaus.org=127.0.1.[2..99], warn_if_reject reject_rbl_client zen.spamhaus.org=127.255.255.[1..255], reject_rbl_client bl.spamcop.net, reject_rbl_client b.barracudacentral.org, reject_rbl_client dnsbl-1.uceprotect.net, reject_rbl_client bl.0spam.org=127.0.0.[7..9], reject_rbl_client noptr.spamrats.com, reject_rbl_client bl.blocklist.de, check_policy_service unix:private/spf-policy, permit Are these fine to go? Many thanks! Best, Mark.
