Good day, My postfix email server has been listed by dsnbl.njabl.org as an open relay, but I'm not sure why. I tested the server from another site, and it passes every test.
My main.cf is setup with the following: __________________ alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases body_checks = regexp:/etc/postfix/maps/body_checks broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix content_filter = smtp-amavis:[127.0.0.1]:10024 daemon_directory = /usr/libexec/postfix debug_peer_level = 2 header_checks = regexp:/etc/postfix/maps/header_checks html_directory = no inet_interfaces = all local_recipient_maps = hash:/etc/postfix/relay_recipients mail_owner = postfix mailbox_size_limit = 15000200000 mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 60480000 mime_header_checks = regexp:/etc/postfix/maps/mime_header_checks mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain, servpt.com, myexg.myemailserver.com; myexg.myemailserver.local mydomain = myemailserver.com myhostname = mail.myemailserver.com mynetworks = localhost, mail.myemailserver.com, plq138, plq139.myemailserver.com, myexg, myexg.myemailserver.local, fdsexg.myemailserver.com, plq138.myemailserver.com, boditree.net, a1w.myemailserver.com, apd.myemailserver.com, awd.myemailserver.com, aaw.myemailserver.com, awa.myemailserver.com, axw.myemailserver.com, aws.myemailserver.com, awp.myemailserver.com, dirw.myemailserver.com, dwi.myemailserver.com, dws.myemailserver.com, ewc.myemailserver.com, fcwc.myemailserver.com, ndw.myemailserver.com, taw.myemailserver.com, twd.myemailserver.com, uawn.myemailserver.com, uww.myemailserver.com, wahq.myemailserver.com, wrc.myemailserver.com, parts.myemailserver.com, parts2.myemailserver.com mynetworks_style = host newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES relay_recipient_maps = hash:/etc/postfix/relay_recipients resolve_dequoted_address = yes sample_directory = /usr/share/doc/postfix-2.2.10/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name smtpd_null_access_lookup_key = <> smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/dsn_exceptions, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, permit_mynetworks, check_sender_access hash:/etc/postfix/access, check_sender_access hash:/etc/postfix/dsn_exceptions, reject_rbl_client relays.mail-abuse.org permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client bl.spamcop.net, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client dnsbl.njabl.org, reject_rbl_client cn.rbl.cluecentral.net, reject_rbl_client smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = myemailserver.com smtpd_sasl_security_options = noanonymous smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/dsn_exceptions, reject_rhsbl_sender rhsbl.ahbl.org, reject_rhsbl_sender hash:/etc/postfix/access transport_maps = hash:/etc/postfix/transport unknown_hostname_reject_code = 550 unknown_local_recipient_reject_code = 550 _______________ njabl.org did a relay test where they send a msg on my email server from sender postmas...@myemailserver.com, and it apparently sent back to them, despite the fact their mail server was not my domain. Where is the loophole in my config?
