3. Alias ID on MUA:
We already agreed that Downgrading of Alias is good practice and to be followed by email servers while communicating with legacy systems , however we have not discussed how Alias will be made available on MUA and if there are many Alias, than which will be used for downgrading.
I think it is a bad practice to offer a downgrade to something other than an old-style ASCII address - and this should be under the hood, with the user getting some simple extra tag in the interface to note they are writing to a downgraded address - for example "大口茶人生" <茶人生@大口。中国> might be downgraded to some ASCII server, and mapped to "大口茶人生 !!chaals@yandex.ru" <chaals@yandex.ru>. A more interesting question is whether it would be useful to help "upgrade" by being able to carry the original address metadata, so a conversation that had to go through a non-EAI-capable system could be shifted to a primary address when the system in question is upgraded. I'm not sure if anyone is going to take that on in practice though. It is still something of an edge case. There is some other obvious use of the same metadata, for example in managing contacts search in mail systems. cheers Chaals -- Chaals: Charles (McCathie) Nevile find more at https://yandex.com Using Opera's long-abandoned mail client: http://www.opera.com/mail/ Is there really still nothing better?
