Some enterprise email systems, such as HP OpenMail, have "type
coersion" capabilities which can look at file contents and then force
files to be handled as belonging to a specific type.
For example, we use OpenMail to coerce all files with a DOS/Windows
executable signature (first two bytes are "MZ") to be treated as EXE
files ... which we summarily discard and replace with a warning message.
So your method wouldn't work to smuggle an EXE in to *our* network.
'Course, if you're really determined you can just pack it up in some
obscure format ... say by binhexing it, then bzipping it...
