Hi there,
In exchange 2010, I want to block attachments with filenames that begin with the same characters.
I've got a rule that redirects any e-mails that contain attachments with names matching text patterns of...
DHL-
DHL_
However these are still getting through. I'd have thought it would block any files that being with those characters. However i'm now wondering if I need to add some variables to the end to define any character.
Is this correct? Anyone any idea how I'd do it as the number of characters after the DHL but can change.
