Hallo zusammen,
Ich bekomme folgende Fehlermeldung wenn ich eine E-Mail an @aol.de senden möchte:

Bei "www.dnsstuff.com" bekomme ich Folgende Meldung:
====================================================
Location: Germany
Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for xx.xxx.xxx.x is found by looking up the PTR record for
x.xxx.xxx.xx.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.
How I am searching:
Asking h.root-servers.net for x.xxx.xxx.xx.in-addr.arpa PTR record:
h.root-servers.net says to go to tinnie.arin.net. (zone: 62.in-addr.arpa.)
Asking tinnie.arin.net. for x.xxx.xxx.xx in-addr.arpa PTR record:
tinnie.arin.net [xx.xx.xx.xxx] says to go to ns.ripe.net. (zone: xxx.xx.in-addr.arpa.)
Asking ns.ripe.net. for x.xxx.xxx.xx.in-addr.arpa PTR record: Reports that no PTR records exist [from xxx.x.x.xxx].
Answer:
No PTR records exist for xx.xxx.xxx.x. [Neg TTL=86400 seconds]
Details:
ns.ripe.net. (an authoritative nameserver for xxx.xx.in-addr.arpa., which is in charge of the reverse DNS for xx.xxx.xxx.x)
says that there are no PTR records for xx.xxx.xxx.x.
To get reverse DNS set up for xx.xxx.xxx.x, you need to speak to your Internet provider. You could also
check with guardian@mediascape.de., who is in charge of the xxx.xx.in-addr.arpa. zone.
Note that all Internet accessible hosts are expected to have a reverse DNS entry (per RFC1912 2.1),
and many mailservers (such as AOL) will likely block E-mail from mailservers with no reverse DNS entry.

====================================================
Unser E-Mail Server hat die IP 192.168.1.x. Von der Firewall wird die öffentliche IP auf die private umgeleitet.
Welche IP muss ich jetzt in dem Reverse DNS Eintrag angeben?
