Mapping MX servers of one domain onto another domain.   

Hi,
 
I have registered a domain example.com, now I have a client requirement, the 
requirement is as follows.
 
The client has a registered domain client.com, they have a MX record 
pointing to 3 servers, now they want a requirement, to map their MX records 
in client.com domain to our domain example.com.
 
How can this be achieved ???? As example.com is not a authorized server to 
host MX records for client.com.
 
This is the requirement
 
Existing:-
 
client.com (MX records)
client3.com     internet address = a.b.c.d
client2.com     internet address = e.f.g.h
client1.com     internet address = i.j.k.l
 
Requirement:-
 
To map the MX of example.com to client.com, such that all incoming mails 
come to client.com & then route to example.com
 
TIA

Re: Mapping MX servers of one domain onto another domain.   

This isn't possible using MX records. MX records will only direct inbound 
mail to a particular mail host at a time.

You can set up the (client.com) mail hosts to relay to example.com.

Re: Mapping MX servers of one domain onto another domain.   

This is very easy
You must add Example.com to you smtp address space even if you do not assign 
it to anyone and choose exchange to be authorative for it
next
First- If you are NOT running the latest Exchange 2003 Service pack, you can 
either install it (after testing ofcourse) or create a Virtual server to 
accept incoming mail for example.com-you can skip this if you are on the 
latest service pack

Next create an SMTP connector that fowards to smart host at example.com
now...
You must register your MX record to come to client.com for example.com as 
well- this will route all traffic for client.com and example.com to the 
client.com servers

When a message is sent internally to example.com it will route thru the 
bridgehad server to teh example.com smarthost

when a message from the internet is sent to example.com it will be sent tou 
client.com which will re-route it to example.com

You may have to activate relaying for this domain

Hope this helps
