Restoring Mail Configuration in Plesk
Sometimes, Parallels Plesk Panel mail server configuration becomes corrupt and it is necessary to restore it. The restoration is carried out by internal mchk utility, intended for use by Parallels Plesk Panel.
However, as administrator, you can use it for restoring the Qmail and Courier-imap configuration when needed.
By default mchk is running in the background mode.
To execute it in the foreground, use the -v option. For example:
/usr/local/psa/admin/sbin/mchk -v

The control panel connects to the Parallels official update server at URL http://autoinstall.plesk.com, retrieves information on the available releases, then analyses the components installed in the system and displays the lists of available releases and component updates. For each release a brief description of available operations is displayed.
Select the release version that you want to update, or upgrade to. A list of available components appears.
Select the check boxes corresponding to the components you wish to install and click Install. A confirmation screen appears.
Specify your e-mail address. You will be sent a notice by e-mail once update is completed. To confirm installation of the selected components, select the check box and click OK. The components/updates you selected will be downloaded and automatically installed in the background mode.
You can check for errors in the autoinstaller.log file located in the /tmp directory on the server hard drive.
