Detaching And Unzipping Files

In our company we are using GROUP-TOOLS for Mail-Blocking and
virus protection.
The Group-Tools can handele a lot of Command-line Tools to scan
mails for viruses.
All these tools needs viruspattern-files.
In our case it's NAI which needs *.dat files
Well, how to distribute these DAT-Files to our locations
(we have 85 Domino Servers all over Europe)

I created a MAIL-IN Database and replicated it to all
servers where the Virus scan process runs.
The agent below has to be run on newly arrived mail
and will detach any attached ZIP-File to a temporay
directory and unzip the ZIP-File to a target directory.

Pls don't hesitate to contact me if you have any trouble
with the code.
Maybe you send me an email if you find the code useful;
or you spend me a beer (if we ever meet).
At least you deside, whether the code is email- or beerware.
Feel free to use it.
