Is it possible to make Mail require a password on startup? Possible Duplicate:
  Is there a way to password protect individual apps?  




I want to know if I can make Mail require a password to actually do anything, see messages, etc. so no one can just go into my Mail and send messages or see my received messages.
To keep email secure in an unsecured account, webmail may be a good option to use instead of Mail.app, which isn't designed to be secured separately from the account it's being used in.
