Just reminding you that non-ASCII characters are included in most European languages (umlaut, accent....etc.) using Latin scripts. So, consider that when you take your decision to ban those emails too.

Recently I tested sending email from my DataMail 小山@电邮.在线 to some people on gmail. Mostly they report that my email to them goes into their gmail Spam/Junk folder. I deduce that the gmail spam filtering software is treating chinese/unicode email addresses less favourably than ascii email addresses. That seems like a leap. How many of those people speak Chinese natively?
Most spam systems are Bayesian and have been taught to look for patterns that match other spam. Everyone who has taught gmail to recognize "Han in the headers == spam" will have to un-teach it that. I don't know about you, but since I'm not a native user of Han characters I have certainly taught my spam filters such rules of thumb.
A Precisely. As a forum admin, I would cheerfully ban all non-ASCII e-mails for registration, because my user base is not world-wide, but the spammers are. Only reason I am not doing that today, is that the software doesn't know about non-ascii e-mails yet :)
