      There are many anti-spam tools. And they are pretty good. For example, better-known and reliable domains can be added to your whitelist. However, spoofed emails will always be redone because they represent legitimate business emails. SPF, DKIM, and DMARC is a mechanism that will protect your email box and will allow you to get rid of annoying spam, ensuring verification of the sender's domain. Stop spam emails right now!

      Read the article by Gary Williams, a virtualization, storage, and Windows systems administrator, to find out how to configure SPF, DKIM, and DMARC anti-spam solutions.

        Sadly, even those techs don't do all that much for stopping SPAM. They can help, but not much. Their value is often heavily overstated.

          And, sadly, Microsoft has decided to keep DKIM in O365 leaving on-premises Exchange 2019 deployments out in the cold. Third party only. 😞

            Don't deploy exchange. Problem solved.

              Tried that with Kerio. Ugh ... that was not a happy experience.

              Exchange just works. It's low maintenance and easy to deploy and migrate. We've been working with it since the 5.5 days (Back Office Server then Small Business Server).

              And, our on-premises deployments have 100% up-time across the life of the solution set which is five years in most cases. Maintenance has been quite simple since the advent of the Cumulative Update.

                Nothing against Kerio, but hardly the alternative most would suggest to sample the non-Exchange world.

                Zimbra, Kopano, Axigen, MailDaemon, etc. Lots of options that people routinely have great experiences with (like being easier than Exchange.)

                I've not tried Kerio, but have used many. The experiences have been all over the place, but pretty universally easier to deploy than Exchange. Which is acceptable itself, not complaining about it. But by comparison, it required more training and prep and was still harder to do.

                Example... as a certified Exchange Admin, Zimbra was still easier to do. And Axigen easier than that. Axigen, if I remember correctly, is the easiest deployment I've done for email.

                  MS doesn't even get close to that.

                    Timing off the top:
                    1: Install Windows Server 2019 with latest CU slipstreamed in: 15 minutes
                    2: Initiate Exchange install and run: 30-60 minutes depending on guest performance
                    3: Run PowerShell scripts to set up for production: 5-10 minutes
                    4: Exchange SSL setup: 5 minutes
                    5: Done

                      Exactly. That's a bit more than the alternatives. Zimbra, for example, is more like 15 minutes total on top of the OS. OS installs are about the same.

                      SSL only takes a few minutes, must be roughly the same.

                      It's not worlds better, and I never claimed it was. Just ..... easier and faster. You left out a critical piece of Exchange... understanding and acquiring licenses.
