Email Login failures on Linux VPS Hosting Packages :
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.”
This problem occured due accessing Horde through the ISP that has dynamic proxies.
To Resolve this problem you can do the following things:-
1)You can turn ‘checkip’ feature off in Horde server-wide.
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:
$conf['auth']['checkip'] = true;
to
$conf['auth']['checkip'] = false;
Note: This modification can’t be configured per user basis and will affect all Webmail users.
