Set up multiple email domains in Exchange Server

  1. In SBS Server 2003 go to the Server Management Console

  2. Drill down on Advanced Management in the left hand pane

  3. Drill down on First Organisation (Exchange)

  4. Drill down on Recipients

  5. Drill down on Recipient Policies

  6. Right Click on the Default Policy and choose PROPERTIES

  7. Click on the EMAIL ADDRESSES (Policy) tab

Here you will see the email address domains (eg @officefurniture.net.au, @educational.net.au) handled by this server

If the email domain that you require is not in the list then you can...

  1. Click on the NEW button

  2. Choose SMTP and click on OK

  3. Enter @meof.com.au (as an example) into the address box

  4. If you want EVERYONE in the organisation to now have @meof.com.au addresses then tick the box that allows this. (Doing this means that you don't have to remember to do this when you add a new user but it means that EVERYONE in the organisation will automatically get one of these email addresses.)

  5. Click on APPLY and OK

  6. Note that the new email domain is listed in the box now so put a tick against it to activate it immediately

  7. make sure that the correct email address domain is bold to indicate the default email address domain to use.

  8. Click on APPLY and OK

  9. When asked whether this EXCHANGE ORGANISATION is responsible for mail delivery to this domain then tick the box.


To update the user email addresses immediately

  1. In SBS Server 2003 go to the Server Management Console

  2. Drill down on Advanced Management in the left hand pane

  3. Drill down on First Organisation (Exchange)

  4. Drill down on Recipients

  5. Drill down on Recipient Update Policies

  6. Right click on the update policy that you want to execute and select RUN NOW

  7. After a few moments you should see the new email addresses against each existing user if you browse the user details.


Manually set up additional email addresses in Exchange

If you DIDN'T tick the box to give the new email addresses to everyone then you need to go into each user that is to have one of these new email addresses and add it in manually.

  1. In SBS Server 2003 go to the Server Management Console

  2. Drill down on USERS in the left hand pane

  3. Right click on any user and choose PROPERTIES

  4. Click on the EMAIL ADDRESSES tab

  5. If the email address that you want is not there then click on the NEW button and choose SMTP and enter the email address and save it.

  6. Once you have added new addresses click on the one that you want to be the default address and click on the SET AS PRIMARY button.


Setup the MX records for multiple email domains

One further thing - for mail to be delivered to the new email address from OUTSIDE the organisation there has to be an MX record pointing to your exchange server. To do this you need to

Register the domain name with an internet registrar (eg Melbourne IT)

Tell them to where the DNS servers are to point the domain name and also the MX record (the domain name gets pointed to where your web site is hosted while the MX record gets pointed to your exchange server's public IP address (the address of the router)

Note that the two mail.x addresses for Mile End office point to the same exchange server as MEOF while the two main domain addresses point to two different web servers for the MEOF and educational web sites. these two sites may be on the same physical box just with different IP addresses or they may be on different boxes.


Set 3Gb Switch for Exchange/SQL Server

You must change the overall memory allocation on a computer that runs Microsoft Exchange 2000 Server when all the following conditions are true:

You do not have to make changes if the computer does not have any mailboxes or public folders on it (such as a mail gateway).

After you have installed Windows 2000 Advanced Server, you must modify the Boot.ini file and add the /3GB parameter to the startup line. For example:


  [Boot Loader]
  Timeout=30
  Default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
  [Operating Systems]
  multi(0)disk(0)rdisk(0)partition(2)\WINNT="Microsoft Windows 2000 Advanced Server" /fastdetect /3GB

Note Some of the lines above may have been wrapped for readability.

Note Do not add the /3GB switch if you are running Windows 2000 Server, Microsoft Small Business Server 2000, or Microsoft BackOffice Server 2000. If the /3GB switch has been added to the Boot.ini file on these operating systems, it must be removed because it can contribute to virtual memory fragmentation on these systems. This switch is designed for use only with Windows 2000 Advanced Server and later.

MORE INFORMATION

By default, Windows 2000 Advanced Server reserves 2 GB of virtual address space for the kernel, and allows user mode processes (such as the Exchange 2000 information store process, Store.exe) to use 2 GB of virtual address space. Virtual address space for a specific process is allocated at Startup and increases as more memory is used during run-time. It is normal for the actual memory usage (working set) of a process to be much less than the address space the process was allocated. On an Exchange 2000 server that has more than 1 gigabyte of memory and that is home to mailboxes or public folders, you must modify Windows 2000 Advanced Server so that 3 gigabytes are available for user mode applications. For additional information about this /3GB setting, click the following article numbers to view the articles in the Microsoft Knowledge Base:

Note It is very important that the Store.exe process does not run out of virtual address space. When this happens, memory allocations fail (even if there is plenty of physical RAM left) and you must restart the Microsoft Exchange Information Store service.

For example, a server with 2 GB of physical RAM without the /3GB switch in the Boot.ini file will run out of memory when the Store.exe virtual address space reaches 2 GB. Windows Task Manager shows that only about 1.5 GB is actually being used but the server will be out of memory nonetheless.

You may also monitor the virtual address consumption with Performance Monitoring. Add the Virtual Bytes counter for the Store.exe process to ensure an accurate reading of the virtual space. The Store.exe process is the only Exchange 2000 process that you need to monitor; other Exchange 2000 processes will not grow large enough to cause any problems.
