Utilities: Administration: Server: Server Settings: Automatic Maintenance: Purging Old Data
Clean Outgoing Mail Queue
This setting determines how long completed mail messages (i.e., welcome messages and other one time messages) will remain in Mailings: Mailing Status: Mail Queues: Outgoing. The outgoing mail queue will display this number of days' worth of completed outgoing mail messages. Older mail will be deleted from the database.
Choosing "0" will result in all outbound messages being shown and saved by ListManager. This setting is not recommended, however, as the database table will just continue to grow and grow, and the SQL server processing requests for your ListManager installation will get slower and slower.
The length of time ListManager saves mailings sent to lists is configured in Utilities: List Settings: Automatic Maintenance: Purging Archives.
Clean Incoming Mail Queue
This setting determines how long completed incoming mail messages will remain in Mailings: Mailing Status: Mail Queues: Incoming. The incoming mail queue will display this number of days' worth of completed incoming mail messages. Older mail will be deleted from the database.
Choosing "0" will result in all messages being shown and saved by ListManager. This setting is not recommended, however, as the database table will just continue to grow and grow, and the SQL server processing requests for your ListManager installation will get slower and slower.
Purge Old Metric Events
This setting determines how many days performance data about ListManager is kept. By default, this setting is "0", meaning metric events will be kept indefinitely.
Purge Old Web Access Log Entries
This setting determines how many days admin web access logs are kept. By default, this setting is "0", meaning these logs will be kept indefinitely.
