It also provides additional fault tolerance, where if the mail server is down, we can still receive email since these are queued on the MailEssentials server.įor this review, I deployed two GFI MailEssentials servers in my DMZ and configured them to relay emails to the internal Exchange 2016 environment. This way, spam, and viruses are filtered before these emails are received on the mail server, thus reducing unnecessary email traffic. In this scenario, MailEssentials is usually hosted in the DMZ and relays inbound emails to the mail server. Installing MailEssentials on a mail gateway/relay server is commonly used for larger organizations or those that wish to keep MailEssentials and Exchange (or any other mail server being used) separate for any reason, like patching, high availability, and so on. With Exchange 2013 and above, it can be installed on the Edge Transport role or Mailbox role servers. In Exchange 2010 environments, MailEssentials can be installed on the servers with the Edge Server Role, Hub Transport Role or Hub Transport and Mailbox Roles. However, it can be installed on its own servers or it can be installed directly in the same servers as Exchange. Ideally, it should be installed and configured in a way that makes it the email gateway for the organization, both for inbound and outbound emails. GFI MailEssentials can be deployed in a variety of ways.



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.
