I am getting the following error while trying to access webmail through cpanel :

Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:143 (Connection refused) in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129

Solution :

IMAP is not enabled, you can enable that as :

Main >> Service Configuration >> Service Manager >>

imap

Courier IMAP Server
