What does "%plesK_bin%\mchk.exe" command do?


Mchk command does the following:

  1. Restores domain configuration in Mailenable

  2. Restores mail accounts with their passwords and limits

  3. Restores mail lists settings

In other words if you delete mail account in MailEnable, it will be possible to restore domain/mail configurations running mchk command (but content will not be restored).

For more information please refer to documentation at:


All the data created not through Plesk will be removed, such as: mail accounts, domains. In addition, the following is removed if it is created directly through Mail Server interface:

  • MailEnable:

    • maillists
    • groups
  • SmarterMail:

    • contacts
    • calendar appointments
    • tasks
    • notes
    • RSS feeds settings
    • auto-responder settings
    • maillists settings
