As far as I know there is no native feature in Exchange 5.5 to facilitate this.

There are however numerous third party product that will block attachments one I have used is Mail Sweeper.

Are you running any virus protection on your Exchange box? If so, check to see if it has the ability to block attachments. We are using GroupShield which allows us to do so.

I use a combination of NAV for Exchange, and blocking at the firewalls.

NAV for Exchange catches most of them as my internal employees send them, and the firewall catches most incoming .exe's. It is amazing how many fewer jokes get sent around now!

Whoops! I lied. I am blocking attachments with NAV for Firewalls and the firewall itself, and scanning them with NAV for Exchange. It's been awhile since I had to change the configurations.

Sorry for being misleading!

Trend ScanMail works rather well for attachment blocking.

If you are running NAV for Exchange 2.1 or higher, you can edit the registry to block certain attachments based on the extension of the file. And depending if your Exchange runs in VAPI or MAPI mode, you can have it delete just the attachment, or the entire e-mail. Search Symantec's knowledge base (www.symantec.com) and you'll find the instructions on how to do so. I've done it here and it works great.

Depending on how big your mail org is.

Mailsweeper is very good at blocking emails, not only attachments but based on content.

It also will scan SMTP email for virus

Hi,

You can block or allow certain extensions (Attachments) without a 3rd party utility if you use M SOutlook as a client.
If you are using MS Outlook 2000 and above you can set the level of security from the Client (Outlook). You can set the security level to high, Medium or low (from TOOLS>MACRO>SECURITY). Depending on the security level selected different extensions can be blocked. You can then create a simple registry string value to 'unblock' certain extensions. The registry needs to be edited from the local client.There is a document on MS Technet if you search the knowledgebase under Outlook for 'security'. An even more comprehensive approach is to create a security folder on your exchange server (we have it on 5.5) that controls the policy for invidual mailboxes/groups of mailboxes and specify the allowed/blocked. You still have to edit the clients registry to point the PC to the public folder but once you have done one PC you can paste the registry value on a network share and copy to the other clients.
If you require more info then let me know -but do check out the MS site.
