Internal virus impossible ? Not really ... :)

I would suggest using a 3rd party FTP server on the internet......

Subject: [Dshield] My graphics guy sent me the following message this
morning...I'd love to hear comments/thoughts/advice:

Part of me wants to strangle him; the rational part of me wants to find a
more peaceful solution.  FYI, we're using Trend Micro ScanMail, Server
Protect, and OfficeScan.  We've got ISA Server on our border.  I'm hoping to
hearing about other solutions, policy suggestions, etc.  Thanks in advance
for input!!  /Lou

I understand the need for a safe computer network and I appreciate all you
do to maintain ours. I know you devote much of your time to this purpose.
However, it has become increasingly difficult to send and receive data.
Since most data that I receive is either .jpg or .html documents that has
been very frustrating both for the sender and the recipient. I am constantly
trying to keep the folks I deal with aware of not sending documents with
those formats. Knowing the challenges you face, I have a few possible
suggestions for alternative ways we can have a secure system while I can
still be able to send and receive graphic files? 

Can we place a dedicated graphics address on my MAC and internet access on
the other side of the firewall? Treat me like an outside source that
doesn't have access to the intranet except through the firewall and filters
you have installed.

Or can we create a list of approved email sources that are considered
trustworthy, virus free, and that will have the privilege of sending
documents with the formats that are currently blocked.
Or is it possible to create a macro that will scan quarantined documents for
infection and once it has been determined that the documents are safe they
are automatically forwarded to the appropriate party.

Is it possible to turn off the outgoing blocking mechanism? I am assuming
that an internal virus is impossible so what is triggering the deletion of
attachments generated internally? 

Can we find an alternate method of document transmission? The two
maintenance firms we have employed to manage the MAC's have both commented
on the tight security. I don't know of anyone else going to this extent on
the security issues. I am not saying it is not necessary, but I am hopeful
we can work out a solution that would enable me to accomplish what my job
demands. I will help out in any way I can.
Thanks for your patience as we endeavor to find a solution.
