Usually keeping messages intact is a key feature of a mail system. However, you may wish to automatically delete message board posts, RSS feeds, and other objects after they reach a certain age.
Possible use cases:
- High frequency mailinglists where you maintain offsite history
- RSS-Feeds where you don't want a large backlog
- Forums with ongoing discussions
- Mailboxes for mobile clients that should have a limited number of messages
It can be configured at three different levels:
- System default (//Administration->Edit site-wide configuration->Auto-purger//)
- site wide configuration for public rooms
- per private mailboxes
- Floor Policy (//Administration->Add, change, or delete floors->[Choose Floor; Edit]->...?)
- Per Room settings (//Advanced->Edit or delete this room->Message expire policy//)
- Individual setting for this room
- default floor policy
