Clean Incoming Mail Queue

This setting determines how long "done" mail messages will remain in the Incoming Mail queue. Specifically, the incoming mail queue will display xx days worth of incoming mail messages which are "done". Keep in mind that this only removes the messages from view, however they are still in the database (for non-SQL versions) and will remain so until the "dbupgrade" utility is run.

Choosing "0" will result in all messages being shown until they are manually removed from the database. Keeping all incoming mail will cause your ListManager installation to become slower and slower. The SQL Server will have more data to organize, and so inquires involving this table will be slowed by the amount of data stored. If you don’t regular go back through your inmail records this value should be set to a small value, such as 5.
