 Hello chris-f,
 
 cf DNS Server Response:
 cf No PTR but got: 
 cf x.141.244.212.in-addr.arpa. 86400 IN CNAME x.domena.pl
 
 
 cf # host  domena.pl
 cf domena.pl  A   212.244.141.x
 
 $ host domena.pl
 domena.pl has address 193.239.44.102
 domena.pl mail is handled by 10 mx01.agnat.pl.

domena.pl to byl przyklad

 cf # host  212.244.141.x
 cf 212.244.141.x PTR record not found
 
 $ dnstracer -s . -4 -o -r 1 2.141.244.212.in-addr.arpa
 $ dnstracer -s . -4 -o -r 1 domena.pl
 
 pokazują, że nie jestes nameserverem ani dla domena.pl ani dla
 czegokolwiek pod  244.212.in-addr.arpa.
Czyli trza uderzac do nazwa.pl

Czyli wpisy ktore podalem z binda sa poprawne?

Dzieki za pomoc.

revDNS bind9 exim4

Witam

Przy dostarczaniu poczty na adres u...@aol.com mam w eximie błąd:

2009-04-19 16:07:01 1LupoK-0001KX-Ij == u...@aol.com R=dnslookup T=remote_smtp 
defer (-46): SMTP error from remote mail server after end of data: h
ost mailin-04.mx.aol.com [205.188.159.216]: 421-:  (DNS:NR)  
http://postmaster.info.aol.com/errors/421dnsnr.html\n421 SERVICE NOT AVAILABLE

Dlaczego serwer aola twierdzi, że nie mam ustawionego revDNSa?

Failure! Unfortunately we were unable to resolve Reverse DNS for the IP address 
you entered. Contact your ISP or e-mail administrator to modify these settings. 
Also please note the following points: 

AOL does require that all connecting Mail Transfer Agents have established 
reverse DNS, regardless of whether it matches the domain.

Reverse DNS must be in the form of a fully-qualified domain name. Reverse DNSes 
containing in-addr.arpa are not acceptable, as these are merely placeholders 
for a valid PTR record. Reverse DNSes consisting only of IP addresses are also 
not acceptable, as they do not correctly establish the relationship between 
domain and IP address.

Chodzi chyba o to:

# host  domena.pl
domena.pl  A   212.244.141.x

# host  212.244.141.x
212.244.141.x PTR record not found

W bindzie mam to tak ustawione:

###named.conf.local

zone domena.pl {
type master;
file /etc/bind/domena.pl;
allow-transfer { 194.145.96.21; 193.111.27.194; };
notify yes;
};

//The next is the reverse DNS entry.
zone 141.244.212.in-addr.arpa {
type master;
file /etc/bind/212.244.141.db;
};
