Auszug aus einem DNS-Report für diese Adresse bei DNSstuff.com:
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 if you recently changed your reverse DNS entry (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:
18.104.22.168.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0) (check it)]
FAIL Open DNS servers ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address. Problem record(s) are:
Server 22.214.171.124 reports that it will do recursive lookups. [test] Server 126.96.36.199 reports that it will do recursive lookups. [test] See this page for info on closing open DNS servers.

Probier mal nen Anderen DNS-Server. ggf. mal einen der nicht von deinem Provider ist.
Sind die anderen Seiten die nicht gehen auch so "exotische"??
