Second email on one server

Hello Sembee:

I have two companies in one building, and I have one exchange server 2003.  I need the two companies to have there own email address.  e.g. company one is home and to have email bill@home.org and company two buy  to have a email with joe@buy.org. I have all email coming under home.org at this time.  How can I do this, Please help me.

Create 2 recipient policies. One for home.org and one for buy.org.
Use the filters to select the proper users.
Configure the MX records for both domains to point to your public IP address.

You don't need to create two different policies but can edit the default, unless you want to use filters to apply them two different OU or such like the user the steps mentioned by Exchange Admin

You will need to have a common attribute on buy.org and home.org user accounts for the recipient policy. The recipient policy has to know how to differentiate between the users. Use a standard field, for example - company under the organisation tab on the user's AD account.

This is basically just restating what the others have already said, but in case it's easier for you to follow:

      (1) Modify the DNS for buy.org and set the MX record to point to
           you mail server (i.e. same as for home.org)

      (2) Add the Active Directory record for "joe" to include the email
          address joe@buy.org

      (3) In Exchange Server Manager, open Recipients -> Recipient Policies and
          select Properties for the relevant policy (in our case, "Default")
          Click on the "Email Addresses" tab, then New, and add "@buy.org"
          as a new address. Mark the box next to the new domain as "checked".
          If it asks whether to propagate to all users, select NO (unless you want
          everyone to receive email at the new domain address). Click OK etc.

      The above should allow mail for joe@buy.org to be received by the server.

Refer back to Comment from r-k.

I used the same instruction that r-k gave:

1.  I added buy.com to mx record
2.  in AD created joe@buy and changed the SMTP in AD to joe@ buy.com (when I was setting him up, it was set up as joe@home.org, was I to keep it like that or change it to buy.

3. In exchange server manager open recipients -> recipient policies -> default policy ->
    Selected properties -> new (open email address) which contains custom address, X 400 address,microsoft mail
    address, SMTP address, cc.mail address, lotus notes address.  So I selected SMTP address -> under address I added buy.com and check (This exchange organization is responsible for all mail delivery to this address)

I got an error that "the e-mail address is not valid.  
    ID no c10312e6
    Exchange system manger"

What did I do wrong, did I select the wrong address please I need you help

I think it's because you have to add it as @buy.com, not buy.com

I would suggest testing that the DNS settings are OK first.

As a test, go to http://www.dnsreport.com/ and enter a valid email address at the new domain in the right-hand field and click on "Mail Test"

I am getting no MS records, but I added it under my other mx record under the other company.  I also tested the DNS report and MX---fail and Mail-- fail as will so do I have to set up MX record from this company separately, if that is so, what about the mail server.  I know that is topic is more that the points I have so, what ever I have to do I will do increase the points.  I need this email sys working ASAP.

"I am getting no MS records, but I added it under my other mx record under the other company.  I also tested the DNS report and MX---fail and Mail-- fail as will.. "

Can you please clarify the above a bit. Are you saying that the Mail Test at dnsreport.com failed to find the MX record for your new domain?

Try the following to verify that you do have a proper MX record for the new domain:

On a recent Windows system (XP):

Open a command window.

> nslookup
> set type=mx
> buy.org                       (or whatever the new domain name is)
> home .org                   (just to compare with old domain that does work)

this should give you the MX records for buy.org, and also show what machine that MX record points to (name and IP address). That machine should be the one that receives and processes the mail. Presumably that should be the same machine to which the MX record for the older domain (home.org) should be pointing.

Re. the rest:

"...so do I have to set up MX record from this company separately, if that is so, what about the mail server."

I am not clear what you mean. The MX record for the new domain should be setup at the DNS server that is authoritative for the new domain. The mail server should stay the same (i.e. the MX record for both domains can point to the same old mail server).  For example, the MX records for both home.org and buy.org can point to a server named "mail.home.org".

Hope I am making sense and not misunderstanding your question. Good luck.

Thanks for the compliment and the accepted answer, but you should only accept the answer if it helped you solve the problem (or least get you closer). If things are not quite working yet please write back, or maybe start a new thread with an updated summary of where you are so that more people can participate.

It is working just find, what was wrong was that I did not have any MX record setup on the domain but I had only set it up on the other domain connected to the mail server.  So when you sent me the link to test the DNS and Email, I had an error on MX records.  I corrected that problem.  Anyway, your comment was very, very good.  I just tested the email address and it is find both internal and external mail is receiving now.

One more question, I had set up users for the other new company (cc@buy.com employees) to receive emails from with home.org domain name (e.g. cc@home.org).  How do I set it up for them to receive email with buy.com and not receive mail with home.org since they are in the server already? I don't want them to have two mailboxes. Also not to lost any mail coming in from all person the gave they email to.

Really glad things are working!

"I had set up users for the other new company (cc@buy.com employees) to receive emails from with home.org domain name (e.g. cc@home.org).  How do I set it up for them to receive email with buy.com and not receive mail with home.org since they are in the server already? I don't want them to have two mailboxes. Also not to lost any mail coming in from all person the gave they email to."

That should be easy, use the Active Directory control panel, right-click on one of the users, select Properties, then "E-mail Addresses" click on "New" and add the smtp address for the new domain (e.g. add joe@buy.com).

If you don't want them to miss any incoming mail at the old address, leave the old address in there. Both mails will arrive in the same mailbox, so there won't be two mailboxes.

If you want the default "return address" for that person to also be "joe@buy.com" (and I think you do), make sure that address is "bold", otherwise highlight the address and click on the "Set as Primary" button.
