[UA-discuss] Would this be in scope or not?

[Don Hollander]

Brent:

Where are conventions/ good practices/best practices for the localname part of an e-mail address developed?

Is this something that the UA group could facilitate during a face to face gathering?  If so, should it?

Could these conventions (etc) be language or script specific?  For example, by convention not supporting a dot in a right to left script.  (This way you can determine which is the domain and which is the local name part - the domain always has a dot.)

The standard for the mailbox name (as in mailbox at domainname) is that the
treatment of the mailbox name is up to the domain name.  "Dots" are
immaterial to mail operators (which has proven to be a surprise), the "+"
might be treated specially, etc. I squirm when I think that there's a
desire to think of email names as global and unique.  So, in a way, it
seems like the wrong foundation for an ICANN effort.  (Languages have had
to adopt '@' already.  Not sure about '+' and other syntactic sugar in
mailbox names.

The practices mentioned here --- immaterial dots, treating +substrings differently, case insensitivity ---  have evolved outside the context of internationalized email addresses. I believe IC! ANN and this group can have a real impact at promoting EAI (RFC 6532 et al) adoption while taking no stance on subjective local-part practices like these.

(There might be areas where we choose to weigh in: local-parts are technically case-sensitive, but one could imagine that there are security implications if an e-commerce site were to allow user at example and User at example to be separate accounts. But those problems already exist and are not specific to EAI.)

mailbox names, I think that would be quixotic.  Then again maybe tackling mailbox names isn't necessary, maybe all we really need to do is get clients to work with an expanded definition of what a mailbox name is.
(Lurking in me is the thought of "variants" and how they might cause trouble in mailbox names if there's no canonical form as defined in IDNA
2008 for domain

[[Ram]] The goal would not be for ICANN to drive either the standard or adoption. Instead, the goal would be for ICANN to help improve awareness of the problem space, and then provide a coordination function so appropriate parties can determine solution sets for the defined problems.
