- Plesk for Linux
Mail field is missing under Plesk > Tools & Settings. Mail component is shown as installed in Plesk installer.
The following command shows similar output:
# plesk bin mail -i
Mail service is not installed in Plesk.
One of mail components is not properly installed and that is why is not correctly detected by Plesk.
Open Tools & Settings > Server Components and press Refresh . If this did not help, try to remove the mail components and install them back using Plesk installer.
