Sending email from multiple domains

As you may know, you can configure SBS/Exchange to handle more than just one domain name for sending/receiving email by setting up an additional recipient policy for each domain that you want. For example, my SBS server at home is configured to use kwsupport.com as it’s primary domain name. However, I also have it configured to handle my wife’s art business emails, under a separate domain of swgalleries.com.


We also know that we configure SBS so that a user could have a designated email address for each such domain. The question is this: how do we configure SBS to allow that person to send and reply to emails using the appropriate, specific email address?


Example: let’s say our SBS server is configured to handle email for the following three domains: domain1.com, domain2.com, and domain3.com. And you have a user (Bob) who has email addresses of bob@domain1.com, bob@domain2.com, and bob@domain3.com. How do we set up things so that Bob can send and reply to emails for each?


Doug Geary offered the following solution from the MS Smallbiz listserve:


Setup 3 users: (DO NOT make a “bob” account, it won’t work)
bob1 – Bob Jones
bob2 – Bob Jones1
bob3 – Bob Jones2


Go back into bob2 and change the name to Bob Jones. Same for bob3.


Alternatively, you could change the display name to Bob Jones (domain1.com), Bob Jones (doman2.com), …


Assign emails as follows:


bob1:bob@domain1.com bob2:bob@domain2.com bob3:bob@domain3.com


Forward email from bob2 and bob3 to bob1


In the bob2 account, give bob1 full access to the bob2’s email.


In the bob3 account, give bob1 full access to the bob3’s email.


Wait an hour for the AD to propogate…


Sign on as bob1. Open Outlook, assign the bob1 exchange account to Outlook.


Open a new message. Click the drop down beside “Options” in the compose window and choose “From”.

  1. I used a similar method to this but rather than forwarding the mails to one account, I provided access to both (in my case) mailboxes through the Outlook client, enabling the user to seperate incoming mail for each domain (which in this case were different companies)

    Technically, i guess this uses a CAL – could anyone clarify that?

  2. Neat solution! I too wonder about how many CAL’s that would eat us… Perhaps there is a solution using mail enabled public folders instead.
