Exchange 2003 and Multiple Domains.

Hello there.

I'm fairly new to sbs and exchange, and i have the following situation.

A particular user has an account and an email address on the server as [email protected]. This is all fine, as the domain on the server is set to company1. However, he also wants to send and recieve mail through the server as [email protected]. He wants to keep the addresses totally seperate, so i thought this would be easy by adding 2 seperate accounts to SBS, one being joe1 and one being joe2.

The emails are recieved using the pop3 connector, and everything is fine for [email protected]. The problem i'm having is with the second account. E-mails are recieved fine and delivered to joe2's email box, but whenever he sends out, it sends out as [email protected]. So I changed the smtp address to [email protected] and unchecked update address but when it is set like this, the mails no longer get recieved, its like they are disappearing into a black hole.

Any ideas? or any other way of dealing with this?

Thanks

Hello Simon,

I am not exactly sure why you are having this problem is but I have some comments and advice which may help.

First of all my experience of using the pop3 connector is very little(I played with it once for about 20 minutes). 

I don't know what the official word is but as far as I can see Exchange has always been designed to be an
SMTP server.  To that end my first recommendation would be to setup the SBS server as the primary MX for both domains.  I can't think of many good reasons to use the pop3 connector.  Setting the server up in this way will also enable you to get more useful diagnostic information if you need to.

Once the SBS server has been set to the primary mx you will need to change the default recipient policy in Exchange to receive email for both domains.

Once you have been through that procedure then you should be able to change the primary email address of joe2 to that of the company2.com domain and send and receive without a problem.

As I say I am by no means an expert in any of the above and I can't tell you why it isnt working at the moment.  But I think setting up Exchange as an SMTP server would be a great start.
