Just now installed whm/cpanel, created some accounts, created mail account in one of them and entered squirrelmail to check the mail. Unfortunately it gives me an error: Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129 Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:143 (php_network_getaddresses: getaddrinfo failed: Name or service not known) in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129 How do I fix it? I don't know exactly, but I read some sites and maybe the problem in dns? I changed ns1.com to ns1.myhost.com in a Basic cPanel & WHM Setup P.S. Im sure that it server configuration problem, not squirrelmail, other mail clients are not working too..
