exe blocking

[John Tenny]

Problem:  trying to send windows builds (exe or zipped exe) as email 
attachments, and the university server bounces them back

Background:  the university has had lots of  virus problems and have 
brought out the sledgehammer solution. I still need to ship the test 
versions around as standalones, but can't get them in or out. I've 
tried removing the exe extension or replacing it with .doc but that 
didn't work. They are blocked even if they have been zipped.

Question: how can I send the .exe files? Given the level of my testers, 
it can't be too complex of a solution.

Thanks,   John
