Hi everyone, I am new to postfix, and i am having an issue. We are not able to get mail from a certain company, our post fix logs show the following. Note: i've removed personal information from the logs Feb 14 15:10:54 SERVER02 postfix/smtpd: connect from mail.example.net[xx.xx.xxx.xxx] Feb 14 15:11:10 SERVER02 postfix/policy-spf: handler sender_policy_framework: is decisive. Feb 14 15:11:10 SERVER02 postfix/policy-spf: : Policy action=DEFER_IF_PERMIT SPF-Result=mail-server.eaxmple.net: 'SERVFAIL' error on DNS 'SPF' lookup of 'mail-server.eaxmple.net' Feb 14 15:11:10 SERVER02 postfix/smtpd: warning: restriction `smtpd_data_restrictions' after `permit' is ignored Feb 14 15:11:10 SERVER02 postfix/smtpd: NOQUEUE: reject: RCPT from mail.eaxmple.net[xx.xx.xxx.xxx]: 450 4.7.1 <email@example.com>: Recipient address rejected: SPF-Result=mail-server.eaxmple.net: 'SERVFAIL' error on DNS 'SPF' lookup of 'mail-server.eaxmple.net'; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<mail-server.eaxmple.net> Feb 14 15:11:11 SERVER02 postfix/smtpd: disconnect from mail.example.net[xx.xx.xxx.xxx] Now, their front end mail server is mail.example.net and their new back end server is mail-server.eaxmple.com The first thing i noticed was the misspelling of their domain name in the mail-server (mail-server.eaxmple.com) So i told the it, was thier issue, and not ours. The problem is this. eaxmple.net is in the domain example.net, The mistake was made a while ago, and never fixed. Is there anyway i can get postfix to allow mail from this company with out them fixing their problem, as it they claim it is our problem. here is a copy of my postfix config. # Requirements for the HELO statement smtpd_helo_restrictions = permit_mynetworks, warn_if_reject reject_non_fqdn_hostname, reject_invalid_hostname, permit # Requirements for the sender details smtpd_sender_restrictions = permit_mynetworks, warn_if_reject reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unauth_pipelining, permit # Requirements for the connecting server smtpd_client_restrictions = reject_rbl_client sbl.spamhaus.org, reject_rbl_client blackholes.easynet.nl, reject_rbl_client dnsbl.njabl.org # Requirement for the recipient address smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, check_policy_service unixrivate/policy, check_policy_service inet:127.0.0.1:2525, permit smtpd_data_restrictions = reject_unauth_pipelining # require proper helo at connections smtpd_helo_required = yes Can someone please help me out? Apperenlty, we are the only place they can not send mail to, and I would like to make a work around so we can receive mail from them without waiting on them to fix thier problem. Thank you in advance.
