multiple email domains

[naserb]

We have two domains xyz.com and abc.com in windows 2000 and exchange 2000 server.We have our own DNS server.We are now using xyz.com domain for email.I want some users to receive emails on both domains.I did the necessary procedures on exchange server but still cannot use abc.com domain successfully.Is there anything to do on dns server so that both domains will be active.
Thanks for any help

 

[Serbtastic]

Do you have an MX record in DNS for both domains pointing to your Exchange server's IP address?

 

[naserb]

Thank you for your response.
yes.I have an Mx record in DNS pointing to both domains

 

[ChrisAC]

Does the MX records for both domains point at your Exchange server? Is your exchange server configured to accept mail for both domains? What happens when someone tries to send mail to abc.com?

Is the mail being bounced, delivered ... what? Give us a clue!

Chris.

1- We can receive and send emails through xyz.com.But when anybody try to send us an email using abc.com he gets an error message:
" Delivery to the following recipients failed" and the diagonostic code will be :
"smtp;550 Unknown local part " and he can not send the email.
2- Exchange Server is configured to accept email from both domains.
3- I operated nslookup like this
>nslookup
default server: server1.xyz.com
address: x.x.x.x

>xyz.com
server: server1.xyz.com
address:x.x.x.x

Name: xyz.com
Addresses: x.x.x.x, x.x.x.h, x.x.x.j, x.x.x.k, x.x.x.l

>abc.com
server: server1.xyz.com
address: x.x.x.x

Name: abc.com

>set type=mx
>xyz.com
the result will be:

server: server1.xyz.com
address: x.x.x.x
xyz.com
primarry name server: server1.abc.com
responsible mail address: admin
serial:
refresh: 900 (15 min)
retry: 600 (10 min)
expire: 86400 (1 day)
default TTL: 900 (15 min)
>abc.com
the result will be:

server: server1.xyz.com
address:x.x.x.x(the same address as above)
abc.com MX preference=10, mail exchanger=xyz.com
xyz internet address = x.x.x.x
xyz internet address = x.x.x.h
xyz internet address = x.x.x.j
xyz internet address = x.x.x.k
xyz internet address = x.x.x.l

because in xyz we have many hosts

 

[naserb]

I operated this command in nslookup
>nslookup
>ls -d xyz.com
the MX line was:

server1 MX 10 xyz

> ls -d abc.com
the MX line was:

abc MX 10 xyz

What are the authoritative dns servers for your 2 domains? Have you tried the same nslookup query on those servers?

 

[naserb]

We have One physical DNS server that has the 2 domains and so I tried the nslookup on this server for the 2 domains as illustrated above.

 

[Serbtastic]

You didn't answer my question.

What are the authoritative DNS servers for your domains? Is it your own DNS server? Or is it set to your registrar's DNS servers? Or to a third party DNS provider?

 

[naserb]

It is our own DNS server

 

[Serbtastic]

Once again, you didn't answer my question.

What are the authoritative DNS servers for your domains?

Go to

http://www.networksolutions.com/cgi-bin/whois/whois

and type in your domain name in the search box. What DNS servers are listed for your domain name?

 

[naserb]

The first domain is .ca and makes no match
The second domain is .com and under "domain Servers in listed order" : it is blank ;no dns servers.
Does this indicate anything.

 

[ChrisAC]

What are the two domains?

Chris.

Yes, it indicates that your registrar has no DNS info listed for your .com domain. As such, nobody will be able to access any hosts in this domain (www, ftp, mail etc).

Go to CIRA's website (

http://www.cira.ca)

and check your .ca domain's DNS info, and see if it has DNS servers listed.

 

[naserb]

First of all thank you for helping me.I realy do appreciate it.
1- for the domain .ca the following information is obtained:
DNS1
ns1.primus.ca
DNS2
ns2.primus.ca
2-for the domain .com, we can only use

http://www with

it, but we can not use mail.
Thank you again

Primus.com and primus.ca MX records point to different servers.

This is your domain, right?

We are with primus.ca
What to do now?

 

[ChrisAC]

"We are with primus.ca" .... what ... is this your provider or your own domain?

Please, just confirm the domains and then maybe we'll get somewhere!

Chris.

I contacted primus (which is our Registrar) and they clarified that the mail for our domain .com is on their server while the mail for our domain .ca is on our own server(This is from two years long ago before I worked ).I asked that the mail for our domain .com to be directed also to our own server.This will take until the end of this day

 

[naserb]

Our domains are automotionshade.com and silentgliss.ca
