you have more trust in ISP DNS servers honouring TTLs than I do. if you can only get a dynamic IP at home and would like to host mail there yourself, in a machine which only you have physical access to, etc. (i.e. do *not* want to keep your email archive on a VPS), you could rent a VPS and use it as a tunnel endpoint instead.
