[enum-wg] ENUM-capable email client?

An E.164 number may can considered as an identifier of some person, different applications can get corresponding address information by ENUM resolving. 

I also think that for MUA it should firstly turn an E.164 number into an appointed Email address, which is convenient to access destined person and also can be flexible to change when needed, not ENUM as a new fixed Email address like +861062619750 at e164.arpa.
