Blocking Internet mail to 1 group?

By supermom ·
We are running Exchanger server 5.5, with Oulook 2000 clients. I want to block all internet email (inbound and outbound) to one group of users only. Can anyone tell me a quick (?) way to do this? (I have already removed the internet email addressfrom the profiles.)

Thanks for any help!

Blocking Internet mail to 1 group?

Having removed the Internet Proxy addressing from their accounts will prevent Inbound Internet mail from reaching them via the Internet Mail Service.

To block outbound you need to add either the group name or the account's individual names to the Reject Messages From window of the Delivery Restrictions tab found in the Internet Mail Service properties.

Tried that..... then successfully sent messages out to a hotmail account.

Any other ideas?

I just tested my concept and it works on my system.

After you set the restrcitions page did you also stop and restart the IMS services?

There have been occasions when the registry is not properly updated and all of the Exchange services needto be restarted to enforce a change (this is usually rare to use this as a last resort)

Also to help enforce it, create another group place all users that will have the ability to send Internet messages and place them in the Accept Messages from.

When you received the message on the Hotmail account, were you able to reply back? If so then you need to remove all SMTP Proxy addresses from the email tab of the Mail account.

Also ensure that your IMS Server is bug free, should be at NT4/SP6a with secuirty patches and Exchange 5.5/SP4 with SMTP security patch.

Good luck.

here's what you need to do.

Removing the internet email address will only stop inbound email. as such, you will also need to restrict the unwanted users from accessing the IMS.

In the IMS properties, select the "Delivery Restrictions" tab andyou will see 2 areas where you can modify the list of "Accept message" or "Reject message". You do not need to modify the "Accept message from". On the "Reject message from", click the "Modify" button. You can now choose from the list of names which you want to be rejected by the IMS.

One more thing to remember, you should also remove the internet email address of the Distribution List group. Once this is all done, you can simply restart the IMS from Windows services or reboot the exchange server. You must restart the services or reboot the server for the changes to take effect.

The file that needs editing is on the client PC. It is called 'MAPISVC.INF.'

An example is as below. Just type ';' in front of the service you want to disable. For example

;IMAIL=Internet E-mail

It takes effect immediately one Outlook has been closed and opened again on the user's PC. It is also beneficial to disable 'pst' creation on client PCs.

[MAPI]
ServiceOrder=AWFAX,MSEMS,MSFS,IMAIL,MSN
[Services]
MSEMS=Microsoft Exchange Server
IMAIL=Internet E-mail
MSPST AB=Personal Address Book
MSPST MS=Personal Folders
MSFS=Microsoft Mail
CONTAB=Outlook Address Book
MSN=The Microsoft Network Online Service
[Default Services]
MSEMS=Microsoft Exchange Server
MSPST AB=Personal Address Book

This wouldn't have worked for us, as our users move from one location to another and do not always use the same pc.
