one of the users is waiting for an email from server currently listed on http://www.dnsbl.manitu.net/lookup.php?value=203.12.160.162
chances are it might get fixed in 12 hours, or, maybe not short of removing dnsbl.manitu.net from my RBL checks, is there a way to 'bypass' this current predicament, and, allow mails from the IP/host? can I simply put IP ? hostname ? both ? in /etc/postfix/client_checks ? or is it /etc/postfix/sender_checks ? as so: 203.12.160.162 OK mail12.tpgi.com.au OK from main.cf: -- smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unlisted_recipient, check_policy_service inet:127.0.0.1:7777, permit_mynetworks, check_sasl_access hash:/etc/postfix/sasl_access permit_sasl_authenticated, reject_unauth_destination, check_recipient_access hash:/etc/postfix/recipient_no_checks, check_recipient_access pcre:/etc/postfix/recipient_checks.pcre, check_helo_access hash:/etc/postfix/helo_checks, check_sender_access hash:/etc/postfix/sender_checks, <====?? check_client_access hash:/etc/postfix/client_checks, <=====?? check_client_access pcre:/etc/postfix/client_checks.pcre, reject_rbl_client zen.spamhaus.org, reject_rhsbl_client dbl.spamhaus.org, reject_rhsbl_sender dbl.spamhaus.org, reject_rbl_client psbl.surriel.com, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client bl.spamcop.net, check_policy_service inet:127.0.0.1:10031 ----------- Feb 13 15:11:59 emu postfix/smtpd[12324]: NOQUEUE: reject: RCPT from mail12.tpgi.com.au[203.12.160.162]: 554 5.7.1 Service unavailable; Client host [203.12.160.162] blocked using ix.dnsbl.manitu.net; Your e-mail service was detected by spam.over.port25.me (NiX Spam) as spamming at Tue, 13 Feb 2018 00:10:11 +0100.
