According to the Antigen documentation, it checks the file header to
determine the type, not the extension. So if you want to block all EXE
programs, you put in a file name of *.* and a file type of EXE and it will block
all EXE programs no matter what name or extension.

Subject: RE: File TypesMaybe I need a bit of an re-education then. I have renamed a executable (Small program 200Kb) to "program.doc". I could have sword Antigen still kicked it out. That was a long time ago but I thought I had tried that after reading that Antigen could actually tell what an attachment is- not just what it is named.I'll try it again a little later.List Charter and FAQ at:-----Original Message-----

Subject: AW: File TypesAntigen is (currently) not checking the type of the attachment...You could install an additional product like MailMarshal or MimeSweeper to catch renamed files like this. They also have the ability to do an AV-Scan...They act as a Mail-Server in front of your exchange box and will forward the mails according to your rules to the exchange server.If on the same server you have to change the smtp port for the exchange server...RickiList Charter and FAQ at:-----Ursprüngliche Nachricht-----

Subject: File TypesI know Ive asked this before, but I dont think anyone had a clear answer.Id like to find software that will scan the file TYPE and not Extention name and filter accordingly.Currently we use NAV for Exchange. We can filter by extention, but why cant we filter by file type?For example, an EXE file has a certain file HEADER that identifies it as an EXE.. why cant we pick it up that way?We have users renaming exe files as .me for example, and we cant spend our days chasing file extentions to eliminate this security hole.any ideas?Michael RossNetwork Analyst 2Panduit Corp.If at first you don't succeed, Skydiving isn't for you.List Charter and FAQ at:
