Quirks
======
This implementation is a work in progress.
- Stanzas to full JIDs get sifted correctly
- Stanzas to bare JIDs are currently allowed/disallowed for all
resources as a whole, and not for individual resources
- Presence is only sent to available resources, and probes are not
sent for unavailable reasources
- This module currently does not interact with offline messages
(filtered messages are dropped with an error reply)
- Not tested with privacy lists
