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 -- Andrew Sullivan ajs@anvilwalrusden.com
