gfi mailessentials license key could not be verified

As far as the MDaemon team behind the product, I can't say enough good about them. In recent months since the COVID pandemic started, spam and scams have spread faster than Coronavirus. With Security Gateway in place I get a little better sleep at night knowing my Exchange Server and entire network is better protected from the nasty stuff out there. I also wish there were an option for additional antivirus engines to be purchased. I wish it had an Outlook plugin that would allow uses to automatically whitelist/blacklist an email from right in Outlook like Mail Essentials has. You can train I prefer the way GFI MailEssentials does Bayesian training and updates, much more useful. I wish the Bayesian filter had a way to incorporate updates from either MDaemon or a third party for downloading known good HAM/SPAM. The logging is top notch, very easy to see what happened to an e-mail and why.

For the price you get all the expected features and a lot of extra goodies too. Installation was straightforward and setup and configuration were also easy. Spam capabilities are far superior to EOP. Security Gateway was the perfect sweet spot.

We moved from Exchange Online Protection to Security Gateway after trialing several alternatives (both on-prem and cloud based). Once the fine tuning was done it has 'just worked' which is all you can ask for. It is a formidable spam filter and keeps viruses out. If any such tool has been installed, it is necessary to deactivate or remove any rule(s) that monitor IIS Admin - and MMC related processes.Overall the product has met and exceeded my expectations. This issue may occur if there are any debugging tools implemented on IIS or MMC. The dashboard will display Processed Successfully or OK for every email. You may also notice that SPAM emails are no longer being blocked.
