Thanks, My postcon -n |grep reject now shows this: smtpd_data_restrictions = reject_unauth_pipelining smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination reject_unknown_sender_domain smtpd_reject_unlisted_recipient = yes smtpd_reject_unlisted_sender = yes unknown_local_recipient_reject_code = 550 I don't know how to put check_helo_access Do I need to create any separate file for helo_checks.pcre? And do the postmap after? How do I do this? I am really a beginner. Sorry. Help me more.
