Clean Outgoing Mail Queue

This setting determines how long "done" mail messages will remain in the Outgoing Mail queue. Specifically, the outgoing mail queue will display xx days worth of outgoing mail messages which are "done".

Choosing "0" will result in all messages being shown until they are removed from the database. This 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.
