Please let me know if your mail client (MUA) makes just the first part of the following link hot http://somespammer.com日本語.com
I know that Thunderbird includes the Japanese characters and the second ".com" in the hot link. If there are commonly used mail clients that stop after the first ".com" then I think we need to fix bug 4522, otherwise I think it is not a bug. There's no need to reply if your mail client acts like Thunderbird and gets the entire URL. If you do see just the first part as a hot link, reply to me not the list. I'll summarize in a comment in bug 4522 -- sidney
