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.
