This article applies to:

• MailMarshal (SEG)

Question:

• How can I generate and log a hash value for attached files?

Procedure:

In MailMarshal 8.0 and above you can enable MD5 hashing of attached files. The hash values are recorded in the Engine log.

• In MailMarshal 10.0 and above, open the Management Console and navigate to Advanced Settings. Add a new value:
  • Name: Engine.HashUnpackAttachments
  • Type: Boolean
  • Value: True (selected)
• In MailMarshal 8.X and below, open the Registry Editor on the Array Manager. Within the base registry key, navigate to \Default\Engine
  • In version 8.X: HKEY_LOCAL_MACHINE\SOFTWARE\Trustwave\Secure Email Gateway\Default\Engine
  • For information about the registry location for each version, see article Q10832.
  • Enter the value as a new DWORD value named HashUnpackAttachments with value 1.
• Save your registry settings or configuration settings.
• Commit the configuration changes and restart the MailMarshal Engine service on each node.

Notes:

Calculation of the hash is processing intensive. Ensure adequate system resource.
