Default DNS- Mail Issue

Hi,

I've several debian etch servers with latest updates running. This
servers have public IP-addresses.
on server a is my primary public DNS (YYY.Y.YYY.YYY) for serveral
Domains running. This DNS is also apporved and verified by DENIC /
INTERNIC / DTAG .....
on my second server with an other pub. IP (XXX.X.XXX.XXX) i've running a
qmail-server for all Domains.


There is following problem:
If i send to diffent domains mail, i'm getting sometimes for some
domains following error :


195.4.92.211 does not like recipient.
Remote host said: 550 inconsistent or no DNS PTR record for XXX.X.XXX.XXX (see RFC 1912 2.1)
Giving up on 195.4.92.211.

in this case it is freenet that is causing the problem.

i've already checked my dns-setup for typos, or inconsistent entries but
i cand find them. Does i need a special setup on ?

or could this be a qmail-problem.

Thanks for help.

Andre

Hello Andre,

Is your reverse-DNS correct?

Try "dig -x yourip", you should get a name in the answer section. And if
you resolve this name, you should get your IP.

To give the IP a name, you can contact the owner of the IP-range.

With regards,
Paul van der Vlis.
