Review on MailMonitor by Charles Fowler

The easy-to use interface makes it very simple for me as an admin user to see what my users are doing in real time.

It's also great that I can set up rules so they don't have access if their account is inactive or hasn't logged into our system within X amount of days (or weeks). Sometimes there will be issues with mail servers not being able to reach out to them when sending emails through our software but this doesn't seem like anything major at all since we've been using it now for almost 2 years! We're solving problems related to spamming and getting people back onto our website after having previously left without logging back in via other methods such as social media posts etc.
