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.
