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 Aurea List Manager server, and also for billing purposes.
If you have no need for this logging information, you can disable this feature, and you can save some disk space which is used for the Aurea List Manager log database table.
