Nope, that won't work. Besides blocking purely based on name we also run
'file' on the attachments and block based on the type of file returned by
'file'. So, a windows executable renamed from foo.exe to foo.txt will
still be caught as a banned 'exe' file - blocking only based on the name
would be way too primitive.
How did you impliment this? I like the idea of checking the file to see if the extension matches what is returned by the file command.
