with WordPress Sytem in your domain but it’s not available here….

After seting your pop3 mail server, view http://www.yourdomain.com/wp-mail.php to get post from your mailbox, but there comes an error:(wordpress 2.0)

Ooops POP3: premature NOOP OK, NOT an RFC 1939 Compliant server

Bug! You can avoid that by editting the file “…/wp-includes/class-pop3.php” ，find the following words

if($this->RFC1939) {

change to: 

if(!$this->RFC1939) {

Check, it works!
