It may be better to block ALL attachments except those that end with the designated extension for your company (i.e. attachment.linux ) and have the body of the email have directions as to how the attachment type should be renamed.
Then you could have a default error message inform people (your users or the sender) as to your companies attachment policy .... I won't fool myself that we will every implement something like this ..... hah ...

So if someone renames it .zi_, it will probably block it. You may want to test that theory out. As for blocking them, we do it when the need calls for it, and turn it off when things are a bit more mellow. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Waters, Jeff Sent: Wednesday, January 28, 2004 7:39 AM To: Exchange Discussions Subject: Attachment Blocking and .zip files So I know that most of us are blocking the most common attachments but .zip has not usually been included in them. Yes I know that a .zip file has the files we are blocking, however we still have to provide a way of conducting business to our end users. So now for the questions; 1) For those that are not blocking .zip files have you started to reevaluate that decision? If so how are you thinking that you will overcome the business need for attachments to get to your end users? My answer, Yes we are thinking of starting to block .zip files. My initial thought was to have the users rename them to *.zi_ so that it would take manual user intervention to rename the file and open it. 2) For those that are already blocking .zip files how are you dealing with users and their need for attachments? We were lucky on this one, in the 2 hours that it took Trend (thank you Trend!) to get the definition file on the street, we had twenty some messages delivered here. My luck was that due to the Snow & Ice we got our offices were closed on Monday so all the attachments were cleaned during the manual scan Tuesday morning. If we had been at work I'm not sure that one of our users would not have opened the message. As I stated I am looking at adding .zip files to our you can't come here list, I am just trying to get a feel for what ya'all are doing as well. Thanks Jeff Jeffrey R.
