Released: January 10, 2017
The latest release of GFI MailEssentials continues to provide considerable improvements and optimisations for a better product experience and also keeping ahead of the curve with the latest security threats. Check out the list below for the list of all the updates to GFI MailEssentials.
Kaspersky 0 Hour
The latest version of the Kaspersky AV engine features an intelligent cloud service that enables scanning of unknown executable attachments and make decisions if the files are malicious or not.
This feature will be available to all who have the existing Kaspersky AV addon and upgrade at no additional cost. Must be enabled after agreeing to a EULA on data being transferred.
GFI Directory Support
GFI MailEssentials now supports GFI Directory. As part of the GFI suite of products, when installing GFI MailEssentials in a DMZ or an environment which does not have Active Directory, GFI MailEssentials can be linked to GFI Directory and enable administrators to manage users just like they would with Active Directory. This enables IT administrators a lot more flexibility when managing blocking rules for users in such environments.
Improvements to common/known issues such as:
- Manually forcing an AV update to download in full
- UI improvements to quickly clear URI DNS blocklist entries and IP DNS blocklist entries and Auto Whitelist entries
- Disable blocking of specified extensions for password protected compressed files.
This version of GFI MailEssentials contains all the updates and security fixes released that have been released since the previous version.
Released: May 3, 2016
The latest version of GFI MailEssentials (Version 20.1) is a bug fix release that comes bundled with all the previous fixes issued previously via live updates and some other tweaks and improvements under the hood.
The updates include:
- Installation will now be executed with the correct elevated permissions when required
- Emails approved from quarantine had incorrect received lines, causing emails to be incorrectly routed.
- EmailSecurity edition only licenses had some issues with certain AV engines, resulting in them not being loaded.
- When installing GFI MailEssentials on a non-English OS, the released patches may fail to install.
- The Anti-Spam SPF check was failing when a DNS TXT record larger than 255 bytes was encountered.
- When using a remote Active Directory setup, modules which require binding with the Active Directory might not function correctly.
- The Domain Controller used for the remote Active Directory setup will be used as the sole DC to which the binding will always be performed.
- When using the Auto-replies feature, the line breaks used in the auto-reply text might not be persisted in the returned email.
- When using the GFI MailEssentials multi-site feature, the control lists (example: Whitelist and Blocklist) may not synchronise correctly.

Released: January 14, 2016
You asked, we delivered! GFI MailEssentials 20, the award winning anti-spam and email security solution, keeps on getting better through a set of major advancements:
Anti-spam multithreading for improved email throughput
The advantage of a multithreaded program is that it can operate faster on computer systems that have multiple or multicore CPUs, or across a cluster of machines. Using this multithreaded approach, GFI MailEssentials supports a substantially faster email throughput with lower resource consumption.
x64-bit backend and action services processing
64-bit is required for GFI MailEssentials to process high email volume environments more efficiently. The services that would benefit most from this change are the backend services, which handle both quarantine and reporting stores as well as Action Services service.
Remote Active Directory (AD) support
GFI MailEssentials can now be installed on non-AD machines such as IIS SMTP or Edge servers leveraging Active Directory even though it is not locally available.
Information store scanning support for Exchange 2013 and later using Exchange Web Services
This feature allows Microsoft Exchange 2013 (and later) users to leverage information store scanning, in order to scan for malware via Exchange Web Services (EWS).
Exchange 2016, Windows 10 and Office 2016 platform support
GFI is committed to remain abreast with and support Microsoft’s latest technologies. Therefore, this release of GFI MailEssentials is shipping with full support for Exchange 2016, Windows 10 as well as Office 2016.
The above features further equip GFI MailEssentials to better cater for larger environments and MSPs who process large quantities of emails. Not only does the product scale to the volume of mail flow processed but does so seamlessly in the diverse environments it is deployed to.
