Mailbox Polling

If an error occurs on the outgoing mail server, email notifications are not sent and queue in the %NX_ROOT%\site\mail_queue directory. When the mail server becomes active again, after an interval it processes and sends email. You can change the interval to recycle the email that was queued when the mail server was busy.

Notification email messages that the outgoing mail server fails to send are resubmitted until you do one of the following:

• Stop the Mail Daemon (pdm_mail_nxd) that handles outbound email notifications.
• Manually delete the messages from the %NX_ROOT%\site\mail_queue directory.

Set the Email Retry Interval Variable

You can define the time interval (in seconds) to retry failed attempts to send outgoing email to the mail server.

Note: CA SDM does not retry sending messages that the outgoing mail server accepts, but cannot be delivered. For these messages, the outgoing mail server retry capabilities and policies, if any, are in effect.

Retries are on a per-message basis. If the mail server is unavailable for a period, each message is retried when its own timer expires, rather than all the messages being sent at once. However, if you restart the outgoing mail daemon, all unsent messages attempt to be sent at that time, and if they all fail to be sent, their retry timers are all reset at the same time.

The setting (NX_EMAIL_RETRY_INTERVAL) in the NX.env file controls the retry interval. You can change the default retry interval setting on one or more servers.

Follow these steps:

1. Log in to the following server, depending on your CA SDM configuration:
   • Conventional: Primary server
   • Advanced availability: Background server.
2. Navigate to the $NX_ROOT directory
3. Use a text editor such as WordPad to open the NX.env file.
4. Modify the value of to the NX_EMAIL_RETRY_INTERVAL interval you want as follows:

   NX_EMAIL_RETRY_INTERVAL=number_of_seconds
   

   NX_EMAIL_RETRY_INTERVAL

   Defines the time interval (in seconds) to retry failed email attempts.

   number_of_seconds

   Specifies the number of seconds for each email retry interval. The default time is 600 seconds (10 minutes). The minimum value that you can use is 20 seconds. If you set a value that is less than the minimum of 20 seconds or more than 2000000 seconds, the default value of 10 minutes is used.

5. Save and close the file.
6. Restart the CA SDM servers. Fore more information about how to start the CA SDM server, depending on your CA SDM configuration, see the Restart the CA SDM servers scenario or find the information in the Administration Guide.

   The change takes effect.
