Unfortunately No, not in Exchange 5.5.

you would be wise to check out the GFI mail essentials that runs in front of the exchange server to block all offending mail.

You can't import a list of domains. However, you might find it easier to add domains directly to the registry.

As always, take precautions before editing the registry directly. Make sure you have a good, current backup of your system. Creating a fresh emergency repair disk and saving the registry key you?ll change before modifying it are good ideas as well.

Open the registry editor (regedt32.exe) and navigate to the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIMC\Parameters\. In the right pane, double-click on the TurfTable value. You enter the domains you wish to filter as a string, just as you would in the Exchange Administrator program. You can enter as many domains as you like, or paste the domain names from a text file, without all the mouse clicks needed in the Administrator program. If you?re entering more than a half-dozen domains at a time, this will save you time.

Restart the Internet Mail Service to make your registry edit take effect.
