You can restore your mail server functionality in cases when errors appear concerning the mail server misconfiguration or its mismatching with the Plesk internal database. This purpose is served by an internal Plesk utility mchk.exe residing at %plesk_dir%admin\bin\. The utility restores the mail server configuration using the Plesk database data.
Note: The utility restores only configuration of the mail server selected as default in Server > Components Management.
In general, mchk.exe matches the mail server configuration with Plesk database. In case when you execute mchk.exe --all --fix-all, the utility resets forcedly the mail server configuration the following way: it deletes all existing configuration files of the mail server (leaving its content) and then creates them accordingly to Plesk database.
Warning: Use --fix-all option only if the mail server's configuration files are so much corrupt that the mail server itself cannot work with them properly and executing mchk.exe with other options does not solve the problem.
Usage: mchk.exe [options]
