Dear all, I've just made a test from Gmail and my Thunderbird mail client sending a mail to a non-real IDN mail user:
alejan...@años.com.ar - My Thunderbird says: "An error ocurred while sending mail. Tha mail servers responded: 5.1.3 Bad recipient address syntax" (THIS IS A SERVER RESPONSE) - The Gmail webmail says: "One o more mail address in "To:" box is not recognized" (THIS IS A CLIENT RESPONSE) So, I think the IDN domain name support is not complete nowadays, neither by mail servers nor by mail clients. So it's not convenient the IDN mail implementation in this bad situation. What do you think about this matter ??? Really thanks 2010/5/26 Wietse Venema <wie...@porcupine.org>: > Alejandro Cabrera Obed: >> Wietse, thanks...but in Postfix I have to work with the ?o?o.com.ar >> domain name or with the xn--oo-yjab.gov.ar punycode domain name ??? > > Read carefully. > > The MAIL CLIENT must tranform non-ASCII domain names before > sending MAIL FROM or RCPT TO commands. > > Wietse > -- Alejandro Cabrera Obed aco1...@gmail.com www.alejandrocabrera.com.ar
