Hello. First of all I need to confess that I am not very experienced linux/unix user. I have a problem with webmail configured on ispconfig. Users are not able to connect through webmail because of some php error. There is the error : Code: Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:110 (Connection refused) in /home/admispconfig/ispconfig/web/webmail/inc/class.uebimiau_mail.php on line 66 Warning: Cannot modify header information - headers already sent by (output started at /home/admispconfig/ispconfig/web/webmail/inc/class.uebimiau_mail.php:66) in /home/admispconfig/ispconfig/web/webmail/msglist.php on line 64 Can somebody please help me to solve this problem?
