Resolving GFI MailEssentials Email Processing Issues

Information

To resolve issues with GFI MailEssentials not processing emails and sending spam to the inbox, follow these steps:

1. Update TLS Settings:
   • Open Windows PowerShell as an administrator.
   • Run the following commands to update TLS settings and enforce strong cryptography:

     New-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -name 'SchUseStrongCrypto' -value '1' -PropertyType 'DWord' -Force | Out-Null
     New-ItemProperty -path 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NetFramework\v4.0.30319' -name 'SchUseStrongCrypto' -value '1' -PropertyType 'DWord' -Force | Out-Null
     New-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -name 'SystemDefaultTlsVersions' -value '1' -PropertyType 'DWord' -Force | Out-Null
     New-ItemProperty -path 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NetFramework\v4.0.30319' -name 'SystemDefaultTlsVersions' -value '1' -PropertyType 'DWord' -Force | Out-Null

   • Reboot the server.
2. Perform Server Cleanup:
   • Stop all GFI services, including the MailEssentials Attendant service.
   • Purge the following folders (do not delete the tnefupck folder, only its contents):
     • %temp%
     • C:\Windows\Temp
     • C:\Program Files (x86)\GFI\MailEssentials\Antispam\temp
     • C:\Program Files (x86)\GFI\MailEssentials\EmailSecurity\Temp
     • C:\Program Files (x86)\GFI\MailEssentials\Attendant\temp
     • C:\Program Files (x86)\GFI\MailEssentials\Backend\temp
     • C:\Program Files (x86)\GFI\MailEssentials\ActionServices\temp
     • C:\Program Files (x86)\GFI\MailEssentials\Antispam\GlobalActions
   • Adjust folder permissions:
     • Right-click C:\Program Files (x86)\GFI\MailEssentials, select Properties, go to the Security tab, and add the "Network Service" account with Full control permissions.
   • Manage message queues:
     • Open Computer Management (compmgmt.msc), navigate to Services and Applications > Message Queuing, and purge any queues with items.
   • Recreate reporting databases:
     • Rename Reports.fdb to Reports.old in ..\GFI\MailEssentials\Data\.
     • Rename Logs.FDB to Logs.old in ..\GFI\MailEssentials\Attendant\data.
     • Run LogsFDBCreator.exe in ..\GFI\MailEssentials\Attendant\bin.
   • Update the registry:
     • Open the Windows Registry (regedit), create a new DWORD key under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GFI\MailEssentials\Config named auhttpallowed and set it to 1.
3. Restart GFI Services:
   • Start the GFI services and set them to automatic start.
   • Monitor the private queues to ensure they do not build up.
   • Check the MailEssentials configuration Logs tab to ensure spam is being blocked.

If the issue persists, consider setting up a hang/crash dump on the Attendant service and contacting the Engineering team for further assistance.
