Configuring the deferred queue timer using the CLI

Follow these steps to set the maximum number of days an email will stay in any of the MTA queues before it is purged. If soft bounce is enabled, emails are moved from the deferred queue to the bounced queue when the queue timer expires. The default value is 5 days.

Follow these steps to specify the number of days an email stays in the deferred queue:

Go to CLI configuration mode.

hostname > enable

hostname # configure terminal

To set the number of days (between 1 and 15) on the timer for all MTA queues:
hostname (config) # email-analysis mta max-queue-lifetime <days>
To reset the timer to the default value of 5 days:
hostname (config) # [no] email-analysis mta max-queue-lifetime

View the current queue timer configuration for the email analysis MTA by checking the value displayed for the max queue lifetime. In the following example, the max queue lifetime is set to the default value:

hostname (config) # show email-analysis mta config
