Hello all, 

   Our organization is blocking all DAT files from entering our organization 
due to Virus' exploiting this file type.  The problem is that our co-workers in 
Europe are triggering the filter (the only ones reporting this issue, for both 
internal and external e-mail users).  When I have them send to an external 
e-mail address so that I can see what may be triggering the filter, I find no 
.DAT files.  The filter is configured to block only .DAT attachments and not 
'DAT' in the body text.  I can find no .DAT files, or any text with the letters 
'dat' that may be causing the filter to block their e-mail.

    What should I look for since there are no attachments?  Could a signature 
in exchange, or some other setting be placing a .DAT file in their e-mails?  
Any assistance would be much appreciated.


Thanks,
