The Account user can control Instant Message processing using the following Preferences:
Accepted Senders besides Buddies: This setting controls incoming IMs from addresses not included into the Account Roster. The following values are supported:
IM Offline Storage: If this option is enabled, and there is no active XMPP or XIMSS session, nor any SIP device registered (if IM delivery to SIP devices is enabled), then the "no address found" error is not returned to the sender. Instead, the IM is stored in the File Storage file, and the positive response is returned to the IM sender.
Always Receive to All Devices: If this option is set to Yes, then incoming Instant Messages are always delivered to all active XMPP and XIMSS sessions and registered SIP clients with messaging capability (if delivery to SIP clients is enabled). Otherwise, messages sent within conversation are delivered to the session or the device specified by the sender.
