> Our CIO (of all people) is trying to send a PowerPoint 2007 document and
> it is getting rejected. It turns out that the .pptx file is really a zip
> archive and within that archive there is a file named "0000.dat" which
> is getting identified as a DOS executable. When I extract the file and
> run the file command against it I get the following:
> 
> $ file  0000.dat
> 0000.dat: DOS executable (device driver) for DOS
> 
> $ file -i 0000.dat
> 0000.dat: text/plain charset=iso-8859-1
> 
> When I look at the file itself, it appears to be a bunch of binary zeros.
> 
> I have tried to to add the following line to the filetypes.rules file:
> 
> allow   -               text\/plain             -                       -
> allow   -               text/plain              -                       -
> 
> with no success.
> 
> I also tried adding  the following line to the filenames.rules file:
> 
> allow   \.dat$                  -       -
> 
> with no success.
> 
> And to save time on an obvious question or two, Yes, I am using tabs
> between fields and Yes I am restarting MailScanner after an update.
> 
> I am hoping that it is something very simple that I am missing. Any
> assistance would be greatly appreciated.
