What’s new in GFI MailEssentials 20.1?

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.
  • The Decompression Engine was detecting certain APK files as corrupted.
  • Under certain conditions, inbound emails may be detected as outbound causing spam not to be detected.
  • Emails released from quarantine may not be delivered to all recipients.
  • During Microsoft Exchange Information Store scanning, an error "Synchronization state data is corrupt or otherwise invalid" may be logged. This will cause the affected mailbox not to be scanned.
  • An email might not be quarantined due to invalid XML characters in its source after parsing.


What’s new in GFI MailEssentials 20?

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.
