Disabling callouts on sender verify

One more question -- one of our servers is using exim 4.68, and unlike 4.63 in the exim configuration manager it does not have an option to enable/disable the use of callouts on sender verify. How is this accomplished on EXIM 4.68 or 9?

"Use callouts to verify the existence of email senders. Basiclly, exim will connect to the mail exchanger for a given address to make sure it exists before accepting mail from it." NOT IN 4.68/9
