First delete messages u read and press reload button on mail box and new one will appear, read them and delete.
Its simple u know, wht u said isnt hack thts zeni claim.
Since its in chinese u may fall in it and loose ur zeni so beware of it and do it as jocer said.
You are from server 1?
If yes you are in a really bad position.
I cant call a player hacker in forum but one guy is using a program to flood e-mail of people.
This flood just bug u e-mail and you cant use email or AH.
For my lucky this guy hates my enemyes and are not doing nothing with my guild, but he did that versus some enemyes and allies (some Sky members).
If you play on SV1, yes it's a hack, he has been doing that, you can delete them, new ones will pop up. Also is too late to block him, e-mails have already been sent, you're only hope is to spend some hours deleting them one by one.
same problem,a friend says me a e-mail to cayennetd to send,she delete hope my mailbox its a friend side from wasabi!...we can wait more not-.- and he make new chars and the same **** again!
