Configuration is set as NOT to receive email from new email addresses

Hello. we have noticed that some external emails (not all) are not generating tickets. We have checked system logs and there are numerous events like below. However, our mail server settings do not have this setting ticked. Is there another section in ServiceDesk where this is configured? Thanks

Email is received from a new mail id : sender@external-domain.com.  Configuration is set as NOT to receive email from new email addresses. Hence, not going to create request for this mail
