Fix_Your_Revers_DNS ... well... GLADLY. But how?
Many servers, same RDNS setup but one server continues to have problems with the roadrunner network (rr.com). Messages bounce back with the Fix_Your_Reverse_DNS message.http://dnsstuff.com/tools/ptr.ch?ip=....yellowdns.com
*ERROR* A record does not point back to original IP.
PASS Reverse DNS entries for MX records OK. The IPs of all of your mail server(s) have reverse DNS (PTR) entries. 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. The reverse DNS entries are:
133.136.44.207.in-addr.arpa ns01.yellowdns.com.136.44.207.in-addr.arpa. [TTL=27953]
