Exchange Server 2003 - New Email Domain

Good Morning,

Hopefully someone may be able to help me as im struggling setting up a new email domain

We currently have the following

1) brighter-connections.com set up and reciving email

2) We have registred a second domain called youritagent.com with dotster we also use a service called Softscan to scan email for spam and virsus which I have set up all the mx records for on dotster and also added this to our Softscan domain.
All I really need to know is what do I need to set up on the exchange server for email to start coming in? or is there something else I need to do?

If anyone can help it would be much appreciated as im really struggling!

Cheers

I would have a read of http://support.microsoft.com/kb/260973

 

as long as your mx-record for the domain is pointing towards your public ip address you should start to receive e-mails. When I set our exchange system up I just arrangeed for the mx-record pointer to be created and all of our e-mails started coming to the server.

 

I am fairly confident you also need to set up Exchange to see the domain as one of its own.

If your mail server is set up to accept any domain mail, your system is prone to spam relaying, so by default most e-mail servers require you to specify the domains they are to handle traffic for.

There also need to be mailboxes configured to receive the e-mails. With Exchange when you create a mailbox, it automatically associates that mailbox with a default domain address. I am not sure if it does the same with additional domains. With the last version I worked on (5.5) you had to manually add the alternative domain address to each mailbox that was to receive mail sent to that domain. More up to date versions may automatically create mailbox@domain_name addresses for all mailboxes.

As I haven't worked on Exchange for a few year I cannot tell you the settings that need to be updated.

 

Exchange problems

You need to setup a new email address for each users mail box for the new incoming domain. A users mailbox can only have one default email address i.e. the mail address that it sends out as. At the moment your users will probably have a default smtp address of xxxxxx@brighter-connections.co.uk. Each time a user send out an email it will be sent out looking like its come from your default email address. You can add additional emailo addresses for any domain to the list of smtp addresses.

The other thing you will need to do is add the domain name into system manager default address policies and also add to recipient policy, defauly policy if you want to so that new addresses are generated for th enew domain each time a new user is added. You can also automatically update all users from here with the new address policy, unless the users properties are set to not automatically update.

If your mx record points to your extrenal public IP address then you need to port forward from the router to somewhere. If you are using a seperate box for email scanning then your router will need to port forward port 25 to that box. You will then need to setup your email scanning software to a) allow scanning of that domain email and b) forward onto the exchange server.

Hope that helps

Nice addition to the thread Pete.

I would just add a note:
If your existing mail domain is already coming into Exchange directly via an SMTP feed (so it is being directed to port 25 of your external IP address), the traffic for the additional domain will come in the same way. Therefore, if your existing router configuration works, then it will also handle the new traffic without modification as long as the MX record points to the same IP address as the MX record for your existing domain.
