Shte polucha artrit ot pisane po tazi tema:))
Ideiata e, che horata se paziat ot spam. Kak se paziat ne komentiram
i ne e moia rabota da davam kraini i okonchatelni ocenki na tova.
Zamisylyt e prost. Kogato tvoia MTA iska da predade elektronno
poshtensko syobshtenie na MTA na mail.bg, abv.bg etc, priemashtia
MTA registrira tvoia IP adres, sled tova izvlicha in-addr.arpa PTR zapisa
mu. Tozi zapis predstavliava pylno kvalificirano ime na host (ili pone
triabva da e). Sled tova se izvlicha A resursen zapis za tova ime na
host i se proveriava dali dadeniat poluchen IP i tozi svyrzvashtiat se s
MTA sa edin i sysht adres.
Shte ti dam dostatychno slozhen primer za pylnota....
Primerno tvoiat MTA host ima IP 192.168.10.1. V zonata na domaina
10.168.192.in-addr.arpa imash niakolko PTR zapisa za oktet 1
$ORIGIN 10.168.192.in-addr.arpa.
1 PTR mta.mydomain.dom.
2 PTR www.mydomain.dom.
3 PTR irc.mydomain.dom.
Posle v zonata na domaina mydomain.dom imash slednite A RR:
$ORIGIN mydomain.dom.
mta 1 192.168.10.1
www 1 192.168.10.1
irc 1 192.168.10.1
Sega razigravame scenaria... Tvoia MTA s IP 192.168.10.1 inicira
sesia kym drug MTA. Drugiat MTA vizhda IP 192.168.10.1. Pravi
zapitvane za izvlichane na PTR za 1.10.168.192.in-addr.arpa.
Poluchava edin ot trite vyzmozhni otgovora:
mta.mydomain.dom.
www.mydomain.dom.
irc.mydomain.dom.
Posle se pravi zapitvane za izvlichane na A RR za poluchania
zapis i ako dvata IP adresa syvpadnat... vsichko e nared.
Mislia, che tozi primer triabva da e iziasnil pone malko
neshtata...
Pozdravi
