I have been exchanging email with some EAI interested people using my EAI addresses and spam filtering systems are now causing problems, as follows:
① I emailed (as a reply to his initial email) a hotmail user with my DataMail 小山@电邮.在线
My email goes to his junk folder. He then marked my email as "not junk". I then sent another email and it still went to his junk folder.
② I emailed (as a reply to his initial email) a gmail user with my Coremail 小山@互联网.网络
This time my email did not get to the recipient. Gmail rejected my email claiming "Our system has detected that this message is likely unsolicited mail. To reduce the amount of spam sent to Gmail, this message has been blocked".
On another busy list devoted to mail system operators, a person from IBM just asked "how much support is there for UTF-8 in email headers?" and someone replied "it's a great spam indicator". It looks like several sysadmins in the US really believe that :-( Did you try to ping people at Gmail/Hotmail over this?
