This article applies to:

• MailMarshal (SEG) 8.1 and above

Question:

• How can I modify settings for node notification of an unreachable Array Manager?

Background:

Communication between the processing nodes and the Array Manager is essential to the health of a SEG installation. Processing will continue if communication is lost, but the administrator should be aware of this issue.

• In version 8.1 and above, if communication is lost the processing node periodically sends an email message to the MailMarshal administrator address.
• By default, this message is sent once an hour if required.

Procedure:

To adjust the interval, or to disable this functionality:

MailMarshal 10.0 and above

Caution: Incorrect syntax in the JSON configuration file will prevent the Controller starting. Back up the file before editing.

1. On the node in the SEG installation folder, locate the file controller.config.json
2. Back up this file.
3. Edit the file. At the top of the file after the open brace { add the following line (where N is an integer setting the number of minutes between notifications).
   • "NoAMNotifyAfterMinutes": N,
   • Note the comma at the end of the line.
   • The default (if the entry does not exist) is 60 minutes. 
   • To disable the functionality completely (not recommended), set the value to 0 (zero).
4. Save the file.
5. Restart the MailMarshal Controller service.
6. Repeat this process on each node.

SEG 8.X

1. Open the Registry Editor on the email processing node (note, not the Array Manager as in most cases).
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Trustwave\Secure Email Gateway\Node
3. Add a value as below.
   • Name: NoAMNotifyAfterMinutes
   • Type: DWORD (values are easiest to understand if entered as decimal)
   • Value: The number of minutes between notifications. The default (if the entry does not exist) is 60 minutes. 
   • To disable the functionality completely (not recommended), set the value to 0 (zero).
4. Close Registry Editor.
5. Restart the MailMarshal Controller service.
6. Repeat this process on each node.
