If you get email from me from a different address (like jason.grossman@anu.edu.au or jason.grossman@dismail.de) then you can reply to that address if you like, but don't put it in your address book because it's not guaranteed to work permanently, whereas jason.grossman@xeny.net is guaranteed to work permanently, or at least until the end of the universe.
