I am poking at the widely used Roundcube web mail package.
One of my test addresses is 测试@电子邮件测试.中国
When I enter it into Roundcube as a username, it turns the domain into
a-labels, 测试@xn--5nqx41au4nqohsp3axcg.xn--fiqs8s and uses that as the
address in the From: line, and to authenticate to IMAP and
submission. I can understand where that came from, but it still seems
Addresses that I put on the To: line seem unmolested.
