The mail is the following:

I've deactivated the links in the copy/paste but if you click on them in the mail you won't go to any NCSoft website but to http://www-ncsoft.dipns.net/ where they'll be sure to steal your account if you ever put your login information there.
If you know people playing Guild Wars who might fall in that trap, spread the word and may the guys behind dipns.net fall under a Chaars patrol!
Dang! Some really have nothing else to do than annoying gamers ?
