From the Postfix's web site: [...] reject_unknown_hostname Reject the request when the hostname in the client HELO (EHLO) command has no DNS A or MX record. The unknown_hostname_reject_code specifies the response code to rejected requests (default: 450). [...] The host command gives to me: host 216.17.141.65 65.141.17.216.IN-ADDR.ARPA domain name pointer hobbes.ssbaptist.net But a more detailed query gives: host -l -t any ssbaptist.net ssbaptist.net start of authority ssbaptist.net brad.ssbaptist.net( 2000080801 ;serial (version) 10800 ;refresh period 3600 ;retry refresh this often 604800 ;expiration period 86400 ;minimum TTL ) ssbaptist.net name server dns.ssbaptist.net ssbaptist.net has address 216.17.141.72 ssbaptist.net mail is handled (pri=10) by mail.ssbaptist.net dns.ssbaptist.net has address 216.17.141.65 linux.ssbaptist.net is a nickname for hobbes.ssbaptist.net pop.ssbaptist.net has address 216.17.141.79 mail.ssbaptist.net has address 216.17.141.70 blocked.ssbaptist.net has address 216.17.141.68 www.ssbaptist.net is a nickname for hobbes.ssbaptist.net mac.ssbaptist.net has address 216.17.141.77 hobbes.ssbaptist.net has address 216.17.141.70 riegel.ssbaptist.net has address 216.17.141.85 ftp.ssbaptist.net is a nickname for hobbes.ssbaptist.net ssbaptist.net start of authority ssbaptist.net brad.ssbaptist.net( 2000080801 ;serial (version) 10800 ;refresh period 3600 ;retry refresh this often 604800 ;expiration period 86400 ;minimum TTL ) That is, hobbes.ssbaptist.net has address 216.17.141.70 (not .65). Anyhow, check what is sent to freebsd.org through the HELO command: this must have an DNS MX or A record.
