Hi all, I have a problem and hope that somebody could help me.
We are running Postfix everything is fine except that some clients of ours cannot sent emails to us. This is the information from var/log/maillog: Jun 27 09:34:19 nico postfix/smtpd[12873]: reject: RCPT from unknown[208.63.55.118]: 450 Client host rejected: cannot find your hostname, [208.63.55.118]; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> In the postfix configuration I have: postconf -e smtpd_helo_restrictions="permit_mynetworks, reject_invalid_hostname, reject_unknown_hostname, reject_non_fqdn_hostname, reject_maps_rbl" I think that if I will remove "reject_unknown_hostname" they will be able to sent emails to us, but I do not want to open any holes for spammers. So, my questions are as follows: 1. Why they cannot sent email to us? 2. Is it possible to change or edit something in Postfix configuration to allow emails from that domain (or from that IP) come through even if DNS check will failed? If it possible, then where, what, and how should I change? Please help me to resolve this puzzle. Best regards and thank you very much in advance.
