I have a problem like that one but, at me, when i try to log in to mail i get this:
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
I installed the newest version of mail for ISPconfig. Dows anyone what should i do to make this work?
