Once completed, make sure that there aren't any firewall rules that prevent access to the update servers:GFI MailEssentials downloads updates from the following locations over HTTP ports 80 and 443:amazonaws.comcdnupdate.gfi.comcdnpatches.gfi.comdb11.spamcatcher.netmeupdate.gfi.comupdate.gfi.comupdate.gfisoftware.comspamrazer.gfi.comsupport.gfi.com*.mailshell.net*.rules.mailshell.netGFI MailEssentials can also be configured to download updates through a proxy server. Refer to the Configuring Proxy Settings article for more information.You can use the nslookup tool to make sure that the domains are reachable. ICMP is usually disabled on CDNs, so ping may not be a reliable tool to use in testing.Verify there are no port conflictsGFI MailEssentials communicates through a variety of ports. Make sure that are no conflicts and that the local firewall solution is not preventing communication through the ports as defined in the GFI MailEssentials Port Description article.Check the proxy configurationMake sure that the credentials supplied to the proxy configuration are correct, as described in the GFI MailEssentials updates are failing when using a proxy article.If definitions are old but updates don't fail, disable caching on the proxy server for the GFI MailEssentials server or exclude the cdnupdate.gfi.com domain.Check Anti-Virus and Backup ExclusionsUpdates may fail if the local antivirus marks the downloaded files as malware.

Author: January 22, 2021 19:08 Updated OverviewThis article provides the recommended Best Practices for the Filter Priority configuration, which will prioritize the various spam filters in order to maximize the scanning efficiency and mitigate spam emails finding their way through to the user's mailboxes. Follow the given recommendations if still receiving spam emails despite having MailEssentials installed.InformationThe information is organized in the following subsections:IntroductionSwitchable FiltersRecommended Filter PriorityAdditional RecommendationsIntroductionMailEssentials is an industry-leading anti-spam and email security solution with multiple filters that can be configured independently to safeguard email users from SPAM and MALWARE.While every organization is different and may require some additional custom configuration of the filters depending on the type of spam emails received, as a general rule, the prioritization presented in this article is recommended, making sure all the filters are enabled. Switchable FiltersYou can toggle the filtering mode for the SMTP-level filters from Full email to SMTP and back as such:Open the GFI MailEssentials Configuration UI Navigate to Anti-Spam > Filter Priority Open the SMTP Transmission Filtering tab.Use the Switch button to toggle the required setting for the available filter:To make the best of SMTP Transmission filtering, use it when GFI MailEssentials is installed on an Internet gateway or when it is the first server to receive emails from the Internet.SMTP level filtering terminates the email’s connection and therefore stops the download of the full email, economizing on bandwidth, and processing resources. In this case, the connection is terminated immediately and emails are not required to go through any other anti-spam filters. This however means that emails will not be quarantined, so you will not have the option of approving or releasing them. If you need to be able to approve emails, consider using Full email level filtering instead.Recommended Filter PriorityNoteDirectory Harvesting, IP DNS Blocklist, and IP Blocklist are each listed twice depending on if you are running in SMTP mode or in Full email mode.SMTP level filters can only be re-ordered with other SMTP filters and will remain at the top of the priority list.The order can be changed as such:Open the GFI MailEssentials Configuration UI Navigate to Anti-Spam > Filter Priority Customize the existing Filter Priority by clicking on to assign a higher priority or to assign a lower priority as described in Sorting Anti-Spam Filters by Priority progressively until the following prioritization is achieved:Directory Harvesting (SMTP mode) Recommended mode for Directory Harvesting; use Full email

Author: December 25, 2020 16:29 Updated OverviewIt is impossible to download the latest virus definitions. The logs show the following error: Error: The request was aborted: Could not create SSL/TLS secure channel.SolutionVirus definition updates take place over a secure connection (HTTPS). In a default installation, if this connection fails, the virus definitions cannot be updated.As a workaround, please follow the steps below:Configure .NET Framework to support strong cryptographySince SSL has been retired in favor of TLS, we must configure the installed .NET Framework to support strong cryptography.Open a new PowerShell window as Administrator and run the following commands:On a 32 bit operating system (x86):New-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -name 'SchUseStrongCrypto' -value '1' -PropertyType 'DWord' -Force | Out-NullNew-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -name 'SystemDefaultTlsVersions' -value '1' -PropertyType 'DWord' -Force | Out-NullOn a 64 bit operating system (x86_64):New-ItemProperty -path 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NetFramework\v4.0.30319' -name 'SchUseStrongCrypto' -value '1' -PropertyType 'DWord' -Force | Out-NullNew-ItemProperty -path 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NetFramework\v4.0.30319' -name 'SystemDefaultTlsVersions' -value '1' -PropertyType 'DWord' -Force | Out-NullEnsure that updates can go throughGFI MailEssentials can be configured to fall back to HTTP, in case a secure connection cannot be established.
