Utilities: Administration: Server: Server Settings: Automatic Maintenance: Logging

Enable Logging

By default, every message posting to a list causes an entry to be written to the ListManager log. Nightly digest and index mailings are also recorded. This information is useful for tracking the overall usage of a ListManager server, and also for billing purposes.

If you have no need for this logging information, you can disable this feature, and you will save a little bit of disk space which is used for the ListManager log database table.
 

Mail Delivery Statistics Interval

This setting defines (in minutes) how often ListManager stores the current mailing speed.

Keeping a more frequent statistical sample enables you to get every finely tuned numbers, but it consumes a little more memory and makes the Utilities: Administration: Server: Delivery Speed web page larger.

Mail Delivery Statistics Size

This setting defines how many points of data you wish to preserve in memory. For example, if your Mail Delivery Statistics Interval is 60 (one hour), then saving 48 data points will keep 2 days worth of statistics.

Keeping a larger statistical sample enables you to look further back in time, but it consumes a little more memory and makes the Utilities: Administration: Server: Delivery Speed web page larger.
