Overview
After applying Patch 7 on GFI MailEssentials 21, antivirus updates are failing.
Process
Ensure that updates can go through
The first step is to allow updates through HTTP, as described in the Setting MailEssentials to use HTTP to download updates article. 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:
meupdate.gfi.com
support.gfi.com
*.mailshell.net
*.rules.mailshell.net
spamrazer.gfi.com
db11.spamcatcher.net
gfi-downloader-137146314.us-east-1.elb.amazonaws.com
cdnupdate.gfi.com
cdnpatches.gfi.com
GFI MailEssentials can also be configured to download updates through a proxy server. Refer to the Configuring Proxy Settings article for more information.
Manually update the Virus Scanning Engines
Once access is confirmed, proceed with the Manual Update Process for the Virus Scanning Engines.
Confirmation
Go to GFI MailEssentials > Dashboard > Updates tab. Verify that the last update attempt was successful for the particular engine by looking at the Last Update date and time as well as the remarks under the Status column which should state No updates currently in progress (last update succeeded).
