note 25891 added to function.mail

I use a server from a foreign hoster without access to php.ini. Before consulting the webmaster of the hoster I want to have an idea which reason can have the following fault: using the mail function from that server it allways returns false, although the server sent the mail correctly. Has anyone an idea which term is set incorrect in the php.ini or where else?! -- http://www.php.net/manual/en/function.mail.php http://master.php.net/manage/user-notes.php?action=edit+25891 http://master.php.net/manage/user-notes.php?action=delete+25891 http://master.php.net/manage/user-notes.php?action=reject+25891
