I'm trying to be fairly aggressive with my file attachment scanning in
Exchange. I run Symantec Mail Security for Exchange of a 2003 Exchange
server and want to block out just about anything that's not needed for
business purposes... I made a list of about 15 extensions, that I deemed
acceptable to be put through the system (.doc, .xls, etc...) Anyhow, I've
set Symantec to block a ton of things.. example:

.a*
.m*
.n*
.o*

This worked well until I discovered that calendar invitations were being
nabbed by the scan engine... I created a calendar event, dragged it to my
desktop and determined that Windows creates a ".msg" file when sending the
invitation.

I modified my scanners to block these extensions instead of ".m*"

It now blocks these attachment types.

*.MDA *.MDB *.MDE *.MDT *.MDW *.MDZ *.mp?" *.MSC *.MSI *.mso"
*.MSP *.MST

The good news is, this allowed the calendar requests to process untouched by
the virus scan engine... Bad news: Replies become quarantined... As soon as
a user accepts a calendar invitation, and replies to the original sender,
that reply is nabbed... Anyone know what type of file that reply is? Its
apparently not an ".msg" file like the invitation itself....
