Re: GMail blocking "executable" attachments

I'd rather see a virus scan than an arbitrary extension block. Though
some might consider it a security breach, I think a systematic deep
scan for malicious files would be more effective. Outlook per default
has blocking methods for executables that can be highly annoying when
they are known not to be malicious, this is my reason for having a
more in depth, 'personalized' solution rather than a generic one.

All-

I've noticed that G-Mail blocks attachments that contain "executable"
files. (A zip file containing an .MDB, and even a zip file containing a
zip file containing an .MDB). I assume they'd block all the usual
suspects, but isn't that sort of the point of sending e-mails with
attachments? Renaming the enclosed .MDB to .TXT allows it to be send
through, so it's not really a major problem. Do you think Google should
be deep-scanning the files for content, or just the extension, and would
running a virus detector against it be just as good?

No real issue here, I just thought it was interesting-not sure if other
major email providers do the same thing.
