The email retention policy for email, trashed, and spam messages is set by COS or for individual accounts. The date is calculated from the day the message is received for incoming messages and the day the message was composed for sent messages. The server manages the message purge schedule.
The duration of time that the server should "rest" between purging messages from mailboxes is set in the Global Settings > General Information page. By default, message purge is scheduled to run every 1 minute.
The attributes are set from the Cos for individual accounts.
