IT Specialist.com would like to highlight a powerful IT security tool for assessing the proper configuration of your email servers that's no cost and simple to use. Like it or not, mailserver security testing is a major CYA function that every network administrator and help desk professional should perform to help stay out of trouble and remain the IT hero of their organization.
Personally, why torment yourself by second guessing whether or not your existing mailservers or MSAs are properly configured, then manually testing and retesting using a painful trial by error methodology. This powerful tool from KnowBe4 saves you time and energy by checking it all for you.
