Re: Question: UseSTD3ASCIIRules on RHS of IMA

   Why should IMAA discuss it at all?  IDNA defines how domain names are
   internationalized, and that takes care of RHS.

Because, as IDNA says, the rules as to where the STD3 hostname rules
should be applied are imprecise and the subject of debate, and the
implementor needs to interpret the RFCs to decide whether they apply
in any given circumstance.

If the RFCs are clear on the matter, then it's surely helpful to the
implementor to document in IMAA the required value of the
UseSTD3ASCIIRules flag for processing IMAs.  (And I'd appreciate a
reference to the RFC that makes it clear whether mail domains are
subject to hostname rules, if there is one.)

If there's any ambiguity or disagreement as to whether the hostname
rules apply, then perhaps IMAA should take the opportunity of
clarifying the situation.
