Failed emails

There may be instances where the GFI MailEssentials email security or content filters cannot scan an email, for example, emails containing corrupted header information. In this case, GFI MailEssentials blocks the email since it may contain malicious content. GFI MailEssentials moves these emails to the following folders, depending on the module that fails:

  • Email security module: <GFI MailEssentials installation path>\GFI\MailEssentials\EmailSecurity\failedmails\
  • Spam filtering module: <GFI MailEssentials installation path>\GFI\MailEssentials\Antispam\failedmails\

Reprocessing legitimate emails that fail

It is recommended to contact GFI Support when a number of emails are being moved to the failedmails folder. When the issue is resolved, emails can be re-scanned by GFI MailEssentials to determine if they are safe to be delivered.


Files with extension .PROP in the failedmails folder are used for troubleshooting purposes. When reprocessing failed emails, these files can be deleted.

Failed emails notifications

GFI MailEssentials can be configured to notify the administrator when an email fails to process.

The administrator’s email address can be configured from GFI MailEssentials General Settings node. For more information refer to Administrator email address.
