Its not about decoding,, if you have local account created as xn-something and your after conversion to punycode is also same.. it will create conflict at many places...

It is not treated as Punycode, because in that part of an email address you can have ASCII, or Unicode, but there is no standard that suggests you might put punycode there so you should not try to decode stuff as if someone did.cheersOn Fri, 29 Dec 2017 07:00:26 +0100, Dr Ajay Data wrote:> Lets discuss in detail when we are there in HK/China.>> However, What if someone create local part email ID which starts >with > xn--@idn , where xn-- is not punycode just a ascii string, >obviously > ACE conversion will FAIL, that was the primary reason >that punycode in > local is not recommended.>> Thanks.>Dr. Ajay DATA | Founder & CEOGet email id like अजय@डाटा.भारत in your > own language,> visit www.xgenplus.comFrom: "John R.
