Setup of SpamTitan was super easy, with excellent documentation and walk-through instructions for configuring your mail server (mine was Office365). SpamTitan gives us a nice daily SPAM report to users, with simple controls for managing quarantined items and exclusions.
SpamTitan is easy to configure with automated reports and very effective at detection. I honestly I don't have anything negative to say. I set it up, and it just worked great! Support were very responsive to all of my questions.
