In my ideal world, MUAs would auto-configure using a one-off probe and fallback process, and remember the results in the same way they currently do after manual configuration. Any subsequent failure should require manual intervention from the user (even if it's just to confirm a re-probe) since it might imply that an attack is in progress.
