Why Outgoing Mail Control management tool is not shown in Plesk GUI?
Server component list was not re-read after Plesk upgrade.
Feature is disabled on server-wide level.
Installed Plesk licence does not include Outgoing Mail control feature.
- Mail server does not support such functionality (Merak).
Go to Tools & Settings > Server Components and click the "refresh" button to refresh Plesk component list.
Go to Tools & Settings > Mail Server Settings to enable this feature.
Check Server Management > Tools & Settings > License Management, and see if there is the line "Outgoing Mail Control On".
- Change mail server to another one.
