I have installed an exchange server for my organisation. Let us say a.com,
and my email address is b.com. I want my b.com addresses and emails secure and as a backup so i registered for new domain name a.com and enabled the cc to all the emails on b.com to mails@a.com.
and this system is working fine. But My main purpose for this was that i wanted to set my intranet emailing system also. that all the external addresses (*@b.com) should route to my intranet (*@a.com ). But when i made cc on server b.com to mails@a.com, they are coming only to mail@a.com address.And they are not being rerouting in my intranet to all.
For example aa@b.com should go to aa@a.com, and bb@b.com should go to bb@a.com, But both aa@b.com and bb@b.com are going to mails@a.com.

(One thing i do not want to change the mx records of b.com)

Please solve my Problem...............

Thanks

Your scenarion seemed a little confusing so I am going to try to reword to see if I understand.

You have 2 domain names a & b.

A.com is being used for the world to send you e-mail.

b.com is used only as a backup, but you also want it to be used primarly between users on your local intranet (why i'm not sure, but I will get into that later)

Now the rest is vague as I am unsure how you have your exchange server mailboxes setup.

If you have 1 mailbox with 2 address' associated with it, then any and all mail sent to either of those address' will go to that mailbox.

If you have 2 mailboxes setup, and 1 address assigned to each address, mb1 = a.com mb2 = b.com, then all mail destined for a.com will go to mb1, same with b.com.
Now something about exchange.

If you have a mailbox and it belongs to 4 distribution lists.

list1@a.com
list2@a.com
list3@b.com
list4@b.com

and you sent 1 e-mail that includes all 4 lists.
Mailto: list1@a.com; list2@a.com; list3@b.com;list4@b.com

Your mailbox will *only* recieve 1 e-mail, not 4.
Exchange is actually very smart when it comes to conserving space. Why, becasue it never really gives the space back.

See I have Made an arrangement on b.com like the following....
1.) *@b.com --forwarded to --> admin@b.com
2.) admin@b.com --cc-> admin@a.com
Now i am receiving all my mails like user1@b.com,user2@b.com and so on on admin@a.com.
See the actual header is the same but they all are only in one mailbox.
Now i want that My Exchange should route all my mail on admin@a.com to users@a.com. i.e user1@b.com (which is in admin@a.com) --should go to-->user1@a.com, user2@b.com (which is also in admin@a.com) --should go to-->user2@a.com.

Two things are there...
1. I do not want to change the mx records of b.com
2. And no forwarding option is there on B.com
Do u have any configuration on Exchange itself to reroute the cc mails from an account to relevent accounts.

I am going to try to restate what you are saying so that I can understand what you are trying to do. Correct me where I am wrong.

I will post an additional "what I would do, if I had 2+ domains to administer (I have 17 domains)"

1. You have 2mailservers.
1 belongs to the a.com
1 belongs to b.com

They are 2 seperate phyiscal mail servers.

2. You do not want to point b.com's MX record to
a.com's mail server (why I don't know, it
would make life easier, you could make
secondray MX records with a lower weight)

3. This part I am unsure of....
either
You have an account on a.com called user1@a.com

?You want all mail recvd on user1@a.com to
forward to the matching mailbox on b.com?

or

You want ALL accounts on a.com to forward
to their counterparts on b.com

or

You want all mail rec'vd on a.com to not only
stay in those mailboxes, but also cc themselves
to the corresponding mailboxes on b.com

Next question, what are you essentially trying to achieve and for what purpose.

You may be trying to achieve the re-routing of mail, but for what purpose are you trying to do this for. Are you trying to keep mail in multiple locations, and if so why? Redundancy?

Was the wildcard character being used as a catch all on purpose?

Your 1st rule
*@b.com --forwarded to --> admin@b.com

Says any mail destined for the b.com will be forwarded to admin@b.com.

Also Which mail server is whichand where did you set this stuff up.

by lordinfidel

First you need to have an understanding of exchange and how it operates.

It is not your normal e-mail server.
When used in native mode it is very powerful.

So now the question is, how do I keep mail on my intranet from leaving the server?

This is done in the routing section of the IMS.

Also, another common misconception is that you need a domain name in order to use exchnage. You do not. You only need a public domain name if you plan on routing mail outside your network.

You can in theory, install exchange on your network. Create mailboxes that have NO e-mail address'. Install Outlook in corporate mode and everyone will be able to talk to each other (ie send e-mail).

E-mail is exactly what it sounds like. Electronicmail. It does not care how it get's there, as long as it get's there. It does not necessarily need a smtp address if it does not plan to be routed thru the net.

I am still thoroughly confused on why you need 2 domain names. The "need it for backup and secure" does not make any sense. If your DNS server that is hosting both domain names goes down, your hosed either way.

Now for the set-up

by lordinfidel

First.... Pick a domain that you want to be used over the net.

Second... Get rid of the other domain name and mail server. There is no need for it. Your causing yourself more heartache then what is needed. Keep your mail in one place and back it up. **If you truly want to keep a real time backup of e-mail there is a way to do it with another mail server and a new entry in your dns table for your current zone.

Now, if you plan on sending out, from what domain do you want it to be from.

In your IMS/routing area, put in that domain and make sure you choose inbound.

Now a mailbox can have multiple address' and it can deliver mail to alternate locations as well as to both the mailbox and the alternate location.

If you point b.com and a.com to the mail server, and in each persons mailbox/address you add a second smtp address for the other domain. Now any mail intended for 1@a.com or 1@b.com will be delivered to 1's mailbox. You don't need seperate mailboxes or servers.
Next... Get some backup software that can backup exchange mailboxes and let you restore at the e-mail level (backup exec w/exchange add-on allows that). Also installing on a 2K srvr allows you to back up the exch store using NTBAckup. I reccomend using BOTH options. Using NTBackup to back up exch to a local disk and BUExec to tape.

What is Native mode. And how can we enable or configure it.

I have one global domain. But i think exchange can not download the mail in it from the smtp mail server. And global domain can work only by pointing the mx record to the exchange. Am i right or wrong?

The "need for 2 domain is only backup and secure" only that's why i have two domains. One another reason for owing the second domain was only to point to my exchnage mail server. and then i am sending the cc to it from my first domain mailbox.

by mastergrab2000

You may have lost me............Hahaa May be

1. You have 2 mailservers.-------------Right
1 belongs to the a.com ----------------Right
1 belongs to b.com --------------------Right

They are 2 seperate phyiscal mail servers. -->Yeah

2. You do not want to point b.com's MX record to
a.com's mail server (why I don't know, it
would make life easier, you could make
secondray MX records with a lower weight---????????????????Really?? But How and What will be the use of it. Will it work only in case of failure of high priority mx record.If it is so it will not be of my use. And really if it can give mail on Both MX records then we can discuss further on this.)

3. This part I am unsure of.... --------Ok
either

You have an account on a.com called user1@a.com
See.... There is user1@b.com, and *@b.com are forwarded to user1@b.com.and *@b.com is forwarded to user1@b.com. This way user2@b.com is also going to user1@b.com. And a cc (of user1@b.com)is going to user1@a.com. What i want is that a Mail Addressed to user2@b.com should go into the user2@a.com mailbox.

wildcard character is being used as a control on b.com.

Your 1st rule
*@b.com --forwarded to --> admin@b.com (Yeah That's right.You can see it as *@b.com ----->user1@b.com [There is only one account on b.com])

Says any mail destined for the b.com will be forwarded to admin@b.com. (yeah Excactly, now we can see user1 in place of admin as you told)
