An EAI address can be in following form while receiving from various email clients / servers. 

उपयोगकर्ता@ xn--p1b6ci4b4b3a.xn--11b4c3d   (local part in Unicode,domain part in puny code)
उपयोगकर्ता@उदाहरण.कॉम (both part in Unicode)
 xn--p1byf7c1a4aj7iyexa@ xn--p1b6ci4b4b3a.xn--11b4c3d  (both part in puny code , theoretical it is wrong as local part can not be in punycode)
xn--p1byf7c1a4aj7iyexa@उदाहरण.कॉम (local part in punycode,domain part in Unicode, theoretical it is wrong as local part can not be in punycode )
?utf-8?B?5biw5Y2X55yf5piH?=@mattkeenan.net (local part in Unicode encoded with base64, domain part in ASCII)
?utf-8?B?5biw5Y2X55yf5piH?=@उदाहरण.कॉम  (local part in Unicode encoded with base64, domain part in unicode)
?utf-8?B?5biw5Y2X55yf5piH?=@ xn--p1b6ci4b4b3a.xn--11b4c3d   (local part in Unicode encoded with base64, domain part in punycode)
test at xn--p1b6ci4b4b3a.xn--11b4c3d (local part in ASCII ,domain part in puny code)
test@उदाहरण.कॉम ( local part in ASCII , domain part in Unicode) .

and XgenPlus (email server) and Spamjadoo (antispam) do support all of them.

Hi Don,
First of all it looks great &ndash thank you for this. Next to the points already mentioned and discussed I just want to add that we should link to the &ldquogood practice guides for Linkification&rdquo and &ldquogood practice guides for validation of domain name&rdquo mentioned on page 2 .
All best,
Lars

Don,
 
Some comments:
 
1.       In the example, under &ldquousername&rdquo it is suggested that &ldquopunycode&rdquo (i.e. xn--abc123) is acceptable. IMO, this is wrong. I&rsquom almost sure the protocol doesn&rsquot require this .
2.       Same thing for second-level and top-level domains. We should not encourage software to display the A-label to end users. A-label is for the wire. Users should see only the U-label. After all , UA is about processing and displaying domain names in a proper manner .
3.       EAI is about Unicode, so not sure why the &ldquoASCII or Unicode&rdquo bullet points. This can be interpreted that ASCII-only email addresses are EAI too .
4.       Since we are mentioning the idea of an authoritative list of TLDs, we should point the reader where to find one .
 
My two quick cents,
Dennis
