Not possible, once the client has received the file then there is no way you
can prevent him/her sending it to somebody else. In fact it sounds a bit
paranoid. If I bought a spreadsheet from you I would be furious if somehow
the said spreadsheet prevented me from sending it to myself using another
email address. If you think like this you should not use Excel as your tool,
the protection is not good at all and as far as I know all pw protection
except for maybe the protection to open the file can be easily cracked with
the help of a simple Google search.
