Nope. It is software that was originally designed to work with a particular email server, but is now growing and expanding. A gateway version of this will be available very soon. It is called (namewithheldfornow) and was originally designed from the ground up to work with an email server to filter and catch viruses and spam before McCrappy or Symanopoly even thought of specific products for email servers. The creator and founder of (namewithheldfornow) is known to many of you, but you just don't know it, even though many of you (as I do) use his free tools to test DNS configurations and settings all the time. Why am I withholding the name? I like suspense and hope to build curiosity for them. When I used to drive trucks, they didn't call me the mad Russian for nothing. ;-)> John T eServices For You "Seek, and ye shall find!" -----Original Message----- From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Maglinger, Paul Sent: Tuesday, July 25, 2006 1:27 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: file filtering best practice?

We use software that bans attachments not only based upon the file extensions, but also the file extension of the file within a zip or other archive file. Therefore, we can allow zip files but still ban zip files which contain executables or other potentially malicious file types.

In dealing with zip files specifically, I'm wondering what is considered the "best practice"? We simply remove the file at our edge proxy, but have been getting a little flack from a few users. Our data shows that nearly 94% of the .zip files that come in via email are infected so I'm not likely to be convinced to allow them through. What say you?
