ATTN:if your email address is "Xia's slave"

OK this has happened a couple of times so I want to address it. In the past as well as more recently, a few of you have sent me messages from email addresses that included an apostrophe i.e. "Xia's slave." Somehow you are able to send out messages from this address, but whenever I try to reply it just bounces back. I think apostrophes are not really valid in an email address. So if you have not received a reply, it is not because I am ignoring you!
