Hi ,
I seem to be having a MX record pointing problem. How do i go abt solving it as per the DNSreport log attached.
1)
FAIL
MX is host name, not IP
ERROR: You have one or more MX record(s) that contain an IP address. This is not valid. A fully RFC-compliant mailserver will not be able to send you mail (although some mail servers will, due to the TCP/IP functions that they use). The problem MX records are:
62.215.205.42.
2)
FAIL
Reverse DNS entries for MX records
ERROR: The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server). The problem MX records are:
42.205.215.62.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0) (check it)]
I am currently using DNS services from an oustide provider & using their name servers for mails hosted on our owned server.
Alex
