In terms of hardware, the requirements depend on a range of factors, such as email volume and the number of antivirus engines enabled, but as a minimum: It shouldn’t come as a surprise that MailEssentials can be installed in a VMware or Hyper-V virtual environment, which is exactly what I did for this review. However, being such a powerful and complete product means that I can only cover its main features briefly in this review. And here we are! In this product review, I take an in-depth look at GFI MailEssentials v21.5 (build 20190321). Having reviewed its GFI Archiver in the past and been pleasantly surprised by it, I was eager to have a look at MailEssentials. One of these solutions is GFI MailEssentials, which provides anti-spam and email security for on-premises mail servers. It offers a wide range of IT solutions, including network performance, patch management, auditing, security scanning, and more. GFI Software is an American developer of IT software founded in 1992.
