## Restoring Mail Configuration

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

Note: You may not wish to restore SpamAssassin settings for mail accounts, as it requires running Perl interpreter. To speed up restoring use the `--without-spam` option.
