G”day: The following comes from the (currently) draft notes from the ICANN60 gathering. There was general acceptance, acknowledging that you’ll never get perfect automated downgrading, that the following would be useful good practice to include in the UASG’s Quick Guide to EAI (as well as our forthcoming Introduction to EAI). Your thoughts, please, but the 10th of November. Thanks. Don The UASG will (after further consultation) include the following as a Good Practice (not best practice) guide for Downgrading: - The EAI Mailbox provider establishes an EAI address and an ASCII alias when the mailbox is set up. - The ASCII alias will have a display name equal to the EAI Address. - When a non-EAI compliant mail system is encountered, the EAI MTA will revert with the ASCII alias and Display Name. - The ASCII Alias should not default to a Punycode conversion of the mailbox name because bi-directional equivalence cannot be guaranteed.
