7245,Keep certain interval to fetch mail message,lilyfan,westi,"wp-mail.php is exposed to run by third-party. If a malicious user loads wp-mail.php continuously, the sequential access to a mail server will occur.
To protect these attack, wp-mail.php needs to be invoked with certain intervals.

I propose a constatnt '''WP_MAIL_INTERVAL''' to define interval minutes, and a option value '''mailserver_last_checked''' to keep the datetime when WordPress checked the mail server.
You can stop using wp-mail.php if WP_MAIL_INTERVAL is set to zero (0).",enhancement,closed,normal,2.9,Security,2.0,minor,fixed,has-patch tested commit early,
