Hello, members of ua-discuss mailing list. I'm Byun, Kyuhong(변규홍) who just came from Ms. Pitinan Kooarmonpatana and many other speaker's excellent tutorial about EAI at recent KrIGF 2021[1]. In South Korea, the country where I live, we have a national holiday named after Korean language's script system, Hangul(Hangeul, 한글, I'm not so sure about the welcomed terminology in this mailing list). It is the 9th of October. Along with the experience of recent KrIGF session, I'm wondering if I could set up a mail server whose domain name is written in Korean (한글날.한국) and whose mailbox is also written in Korean(like 변규홍@한글날.한국). UASG30[2] led me to try `Roundcube` and `iRedMail`, but due to the lack of my experiences regarding domain names itself and mail server, I would be grateful if I could find someone else's trail for relevant attempts. p.s. Please do not hesitate to let me know if this is an inappropriate place to raise such a question like this. -- With Regards, Byun, Kyuhong (변규홍) [1]: https://youtu.be/1cBnCxmQfkI?t=5613 [2]: https://uasg.tech/wp-content/uploads/documents/UASG030-en-digital.pdf
