Hi,
I have done some searching in TechNet and on the Internet, but have not been able to find the answer to my question.

How does one restrict or prohibit e-mail attachments? We are using an Win NT 4.0 server running Exchnage 5.5

Is there some setting in the exchange administrator, or does one need a 3rd party utility? I have searched for the answer but did not discover it.

Any help would be appreciated. Thanks

You would need a third party since Exchange 5.5 does not have this capability. I use McAfee GroupShield for Exchange and it will do blocking based on a file extention, file name or all attachments.

Sorry, We are already commited to a different Anti-Virus program. We are not able to change. Thanks for the Info.

Give the above the points....

Just one clarification....

Groupshield 4.5 Sp2 does the extension filtering. So make sure that if you buy Groupshield it is 4.5 sp2 or later.

Two possible interim options:

If you are worried about attachments through SMTP the set the allowed message size to something small. Of course this will only prevent large files.

If you are running Outlook2K then look up MS KnowledgeBase article Q263297 as a possibility.
