This article applies to:

• Trustwave MailMarshal (SEG)
• Trustwave ECM/MailMarshal Exchange

Symptoms:

• Messages are put in the Deadletter\Unpacking folder with an error.
• Error: "Unpack recursion limit exceeded."

Causes:

Reply:

In most cases, messages that are more than 20 levels deep are not valid e-mails. MailMarshal has a default recursion limit to block such unwanted mail. For example, the recursion limit will prevent some message loops by blocking the looping e-mail when it reaches 20 levels deep.

You can change the default limit from the MailMarshal Management Console (in earlier MaiMarshal versions and ECM, the MailMarshal Configurator).  See Array Properties | Engine Properties | Advanced (in older versions, Server and Array Properties | Advanced | Additional Options | General)
