Workaround / Fix Details

There is a registry key that you can enable so that HTML Sanitizer ignores the malformed html code in an email, thus not failing to process such email. Please go to Windows Registry (regedit) and set the following key from 0 to 1: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GFI\MailEssentials\EmailSecurity\Engines\HtmScriptRemover\ignoremalformedhtml Restart the GFI Attendant service and process that email again.

Required Actions

Apply workaround and close case.
