I've searched for this but I can't find an issue that answers my problem, so I thought I'd ask you all for some help. The problem The issue is that DNS checking sites like DNS Report (the link will report things are fine now because I have a hand-created file in there temporarily) says that my Golgotha.net domain does not have any MX entry. But I disagree! That domain not only has one MX, but also a backup SMTP entry. If it were only dnsreport.com I wouldn't mind, but another DNS checker reports the same error. A "dig" for type MX also turns up nothing. What I've done I created the domain and the MX records with ISPConfig -- the software saving me from ever having to touch a BIND config file is one of its greatest features! Mail seems to work. I can send and receive mail on that domain okay. Data to consider Excerpt from /etc/bind/pri.golgotha.net that ISPConfig created: Code: $TTL 86400 @ IN SOA ns1.golgotha.net. webmaster.golgotha.net. ( 2006071302 ; serial, todays date + todays serial # 28800 ; refresh, seconds 7200 ; retry, seconds 604800 ; expire, seconds 86400 ) ; minimum, seconds ; NS ns1.golgotha.net. ; Inet Address of name server 1 NS ns2.golgotha.net. ; Inet Address of name server 2 ; mail MX 10 mail.golgotha.net. mail2 MX 20 smtp2.easydns.com. ( --snip-- Further below: ) golgotha.net. A 18.104.22.168 ( --snip-- ) ns1 A 22.214.171.124 ns2 A 126.96.36.199 mail A 188.8.131.52 ( --snip-- ) Now, from the working one I copied and hand edited: Code: @ IN SOA ns1.golgotha.net. webmaster.golgotha.net. ( 2006071400 ; serial number YYMMDDNN 28800 ; Refresh 7200 ; Retry 864000 ; Expire 86400 ; Min TTL ) NS ns1.golgotha.net. NS ns2.golgotha.net. MX 10 mail.golgotha.net. MX 20 smtp2.easydns.com. $ORIGIN golgotha.net. ns1 IN A 184.108.40.206 ns2 IN A 220.127.116.11 mail IN A 18.104.22.168 www IN A 22.214.171.124 Why the difference in the MX layout? Anyone have any clues? Whacks with a clue-bat would be appreciated; TIA.
