Re: Open Issue: Splitting of local-part into labels and where?

   If we assume we are going to use punycode, then you prety much *have*
   to split at dots, otherwise you'd have cases where punycode generates
   strings containing multiple consecutive dots.  Yes, you could make
   this valid by generating suitably quoting, but you'd be creating local
   parts that are (a) deprecated by 2822 and (b) stand a significant
   chance of not working on the current Internet.  (See my separate post
   on quoting.)

Oops, as has just been pointed out to me, quoting is valid within the
legal-to-generate grammar of 2822.  I would still voice the concern
that it anything containing quoting is likely to be less than
universally acceptable to currently deployed systems (and we therefore
shouldn't generate it).
