We were having an issue with our on premise exchange server and sending out email. We were up and running in 5 minutes. It doesn't feel as intuitive as it actually is. We were confused at first but once we got a hold of somebody on their end it was a breeze. 5 stars all the way! Thank you for being there when we needed it.

I use MX Layer Security Services including outbound Gateway for a long time. I also use it to manage mail policies and prevent spam and phishing emails from reaching end users. I would say it has almost 100% efficacy in blocking malicious emails. It also provides a lot of control in terms of the ability to modify rules, make exceptions, and search to find what happened to an email message.
