Off topic: MX entry and ISP

2000-07-12 Thread Suresh_Kumar




Hi all, I posted a mail sometime back I think it 
has not reached most of the gusy there was no response from anyone.

How the MX entry and the www entry of a dns 
server go together when the mail server and the web hosting server are with two 
different ISPs of different locations.
I know they are playing with dns entries but 
some of my mails get bounced when the receiving smtp server goes for a 
reverse-lookup.
I would be grateful if someone throw their cents 
in and make me understand.

regards
suresh

Suresh,

no problems for that. DNS servers for the domain will be hosted
on the DNS servers of one provider. In zone file, there will be
records for www and for mail server. 'A' record for the www will
point to the provider's 'A' www server, and 'MX' record will point
to the provider's 'B' mail server.

Owner of the domain should tell provider's 'A' hostmaster what to
put into zone file for the domain.

Dear Suresh,

I am very interested to help you, as I have been System Adminitrator for 
Unix System and
done sometime with DNS management, However Your data is not clear enough, 
and i get confused
from your explanation, therefor I can't reply with useful info.

1) Please provide more real data to analyzi for example does two sites have 
exact name ? or it's different ?
www.a.com and www1.a.com could be the same IP could be different.

2) I could have mx and DNS entry different for example :

www.ong.net.IN  A   202.154.1.1
www1.ong.net.  IN   A   202.154.1.2

You see now ? it's different for MX it could be

ong.net.IN  MX  10  202.154.1.1
branch.ong.net. IN  MX  20  202.154.1.2

Meaning :
1) Mail with ong.net domains go to email server 202.154.1.1
2) Mail with branch.ong.net domains go to email server 202.154.1.2

Btw I am not sure what you're asking, here's a general point
