If you are unable to login into Webmail , and you are getting an Error: “Your Internet Address has changed since the beginning of your Mail session. To protect your security, you must login again.”<\/p>\n

This problem occurred due accessing Horde through the ISP that has dynamic proxies.<\/p>\n

To Resolve this problem you can do the following things:-<\/p>\n

1)You can turn ‘checkip’ feature off in Horde server-wide.<\/p>\n

2)Now login to the Plesk server through SSH and edit the \/usr\/share\/psa-horde\/config\/conf.php file in your favorite text editor.And also Change the lines:<\/p>\n

\n$conf[‘auth’][‘checkip’] = false;<\/p>\n
