Question
Is there a cPanel-sanctioned method to modify Exim's hosts_try_dane configuration?
Answer
As of the time of this writing in cPanel version 96, there is no supported method to modify Exim's hosts_try_dane configuration. We suggest making advanced configuration changes to Exim via WHM -> Exim Configuration Manager -> Advanced Editor, however, hosts_try_dane is not an accepted input variable at this time.
We do have an existing feature request for this functionality at the URL below. Please vote on this feature request if you would like to see this functionality added in a future cPanel release:
Feature Request: Modify hosts_try_dane in Exim
Further information about hosts_try_dane can be found in Exim's documentation:
