WHAT IS TNEF? Transport Neutral Encapsulation Format, or TNEF, is a format of encapsulation used exclusively by Microsoft to send a message using Microsoft Rich Text. TNEF is proprietary to Microsoft products such as Outlook, Outlook Express and Exchange. Lotus Notes does not have the ability to decipher TNEF. TNEF attachments can be generated in two ways: 1) if a Microsoft Exchange's internet mail connector is configured to send TNEF. The default option of the Internet Mail Connector is set to User, meaning the client can select the option of using TNEF or not. The other options for the IMC is Always or Never , OR 2) sending of 'winmail.dat' can be set in the address book on a per-recipient basis. NOTE: The Exchange setting overrides the setting in the Personal Address Book. Also note that the wording of the setting in the address book is different in the various Microsoft mail clients. -----Original Message----- From: Martin Blackstone [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 05, 2001 9:54 AM To: Exchange Discussions Subject: RE: Do your content blockers stop attachment when they are TNEF e ncod ed? OK, you got me. What is TNEF. -----Original Message----- From: Alverson, Thomas M. [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 05, 2001 6:52 AM To: Exchange Discussions Subject: Do your content blockers stop attachment when they are TNEF encod ed? When an attachment is encoded with TNEF, the filename is embedded in the encoded part. We have a filetype filter on our firewall machine, but it cannot tell what is in a TNEF encoded attachment. Once the file gets to our exchange server, NAV can block by extension. Since we are running in MAPI mode, I don't trust this to always catch these. Do any of the content filtering products work with TNEF files?
