mailbox names. UASG and SSAC have historically weighed in

There is no equivalent of IDNA for mailbox names, so we could
be more explicit about our opposition.</p>

<p>Mark,</p>
<p>I definitely agree.</p>
<p>If we run into violent opposition, because many users decide to
view that restriction as churlish, there's a possible fallback:<br>
</p>
<p>E-mail names, unlike domain names, already aren't treated as
"exact match"; for example certain punctuation is ignored.</p>
<p>A more restricted prohibition might give a better balance: insist
that all emoji in an email name are treated as ignorable. That
way, people can add them, as long as the remainder of the name
contains a string of unique code points.</p>
<p>You would be able to have I<span style="font-size:13.5pt;font-family:"Segoe UI
Emoji",sans-serif" lang="DE">❤</span><span style="font-size:13.5pt" lang="DE"></span>NYC, but not if
someone else has INYC.</p>
<p>This slightly more relaxed stance may be a useful fallback if we
find that we cannot get traction with a full prohibition.</p>
<p>A./</p>
<p>PS: this technique doesn't work as well with domain names as it
would have to be implemented by registering all these variants,
thus lead to combinatorial explosion.<br>
