If you’re logged into webmail, and then you get an error like this:
Your Internet Address has changed since the beginning of your Mail session. To protect your security, you must login again
This means that your computers IP address has changed, and plesk does not like that, because it thinks someone could be trying to hijack your session.
To get around this, do the following.
- SSH to the server
- Edit the /usr/share/psa-horde/config/conf.php file in the Plesk server and the change the following line.
$conf[‘auth’][‘checkip’] = true;
$conf[‘auth’][‘checkip’] = false;
Once you do this, it will no longer check to see if the IP address has changed.
