Hello ... is this thing on ?? Antigen http://www.sybari.com/products/antigen_exchange.asp can do this for exchange. If someone sends you an mp3 file or an exe and they rename it, it will still pick it up because it checks the attachments based on extension and file type.

Definitely. It's all too easy to change the extension of a file so it's allowed through a virus scanner/mail management software when it shouldn't be, and then renamed at the other end.

 

We have a similar problem on our file server. We've prohibited people from saving particular files, such as mp3, but they can all bypass it by changing the extension of the file to .zip or .doc.

What do you mean? Something that would block a .EXE file even if the extension was changed to .XXX?

Hmmmm.....interesting.

NAV for Exchange can do this with a registry tweak.. Its in the read me.
What id like is software that filters file types without using extentions.

Your Exchange aware Antivirus SW should be able to do this. What are you using?

Hi there,

We are using Exchange Server 5.5 SP3 on a Windows NT Server 4.0 SP6. Clients are using Outlook 97. Is there a way to prevent users from sending attachment of a specific filetype ? For instance *.mpeg, *.avi an so on ? Both internal and external mail.

Regards,
