Handling undelivered messages

Message delivery options help you control how undeliverable mail is handled. Options for these operations are configured on the page Settings > Inbound/Outbound > Message Non-Delivery Options.

Use the following steps to determine how to handle messages that are temporarily undeliverable due to error situations:

Steps

  1. In the field Retry interval, enter the time for the message retry interval, in minutes.
    Important: Message delivery retry intervals are calculated exponentially. For example, using the default entry of 15, retry attempts are made in 15, 30, 60, 120, 240, etc., minutes.
  2. In the field Maximum retry period, enter the time for the maximum period for retrying message delivery, in minutes.
    The default is 1440.
  3. In the field Notification email address, enter an email address to which to send notifications that a non-delivery report (NDR) cannot be delivered to the original sender at the end of the retry period.

    Mark the check box Use Administrator email address to send these messages to the administrator.

    You must configure the administrator address on the page Settings > General > System Settings (see Setting system notification email addresses).

  4. Click OK.
    The settings are saved.
