[UA-discuss] Suggestion Email validation library to support IEA

[John Levine]

>A standard library that has a  function like validateEmail() eases the support for IEA in web and mobile apps development.

We've been working on this in the IETF.  See

https://datatracker.ietf.org/doc/draft-seantek-mail-regexen/

Also keep in mind that addresses have to be syntaxtically valid, but
just because the syntax is valid doesn't mean the address actually
works.  The only way to check is to send it a message and see if
anyone responds.
