How to enable the Wizard option “Run email domain lookup server” after the wizard has finished?

It doesn’t appear if I re-run the wizard

Also, what is the “lookup daemon”?

Hello,

For this to appear on the wizard, spam filtering feature on System Settings ⇾ Features and Plugins page must be re-enabled first.

Also, what is the “lookup daemon”?

It’s a background process for getting user details for faster mail processing.

Thank you Illia.
