Regenerate the mail configuration in Plesk (mchk)

caution rootMaildebian, ubuntu

Caution: This command changes the system. Understand what it does before you run it.

root@server
plesk sbin mchk --with-spam

Regenerates the mail server configuration for all domains and mailboxes from the Plesk database, including the SpamAssassin settings. Helps after migrations, manual changes, or when mailboxes reject logins although they look correct in the panel. On servers with many mailboxes this can take several minutes.

Note: Manual changes to generated configuration files are overwritten.
