I have a check to reject 'fancy TLDs' as below smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, check_sender_access pcre:/etc/postfix/sender_pcre, check_sender_access pcre:/etc/postfix/reject_domains
cat /etc/postfix/reject_domains /\.bid$/ REJECT We reject all .bid domains /\.biz$/ REJECT We reject all .biz domains ... that works well, but, now have a user who gets a valid inbound rejected Dec 16 15:06:14 postfix/smtpd[8695]: NOQUEUE: reject: RCPT from mail-sy4aus01on2077.outbound.protection.outlook.com[40.107.107.77]: 554 5.7.1 <sen...@abcd.biz>: Sender address rejected: We reject all .biz domains; from=<sen...@abcd.biz> to=<recipient@tld> proto=ESMTP helo=<AUS01-SY4-obe.outbound.protection.outlook.com> is there an easy way, and how, to exempt a specified domain like 'abcd.biz' from my sender restriction ? thanks, V
