Hi, I'd like to use client circle to send my clients notifications about system management, but this is what I have and email are not sent. Warning: fsockopen() expects parameter 2 to be long, string given in /usr/local/ispconfig/interface/lib/classes/ispcmail.inc.php on line 592 Warning: fgets() expects parameter 1 to be resource, boolean given in /usr/local/ispconfig/interface/lib/classes/ispcmail.inc.php on line 593 I configured a circle with only one test user and the email field in the client form is filled with a valid email address. Any suggestions? A.
