Server MUST return <service-unavailable/> for IQ requests to unknown user. (RFC 6120 10.5.3.1.)

Description

RFC 6120:

10.5.3.1. No Such User

If there is no local account associated with the <localpart@domainpart>, how the stanza is processed depends on the stanza type.

For an IQ stanza, the server MUST return a <service-unavailable/> stanza error (Section 8.3.3.19) to the sender.

Currently Openfire returns a non-error response, e.g. when sending:

None

If I understand the history of this issue correctly, then we had a fix, but that got reverted, because it clashed with pre-existing code (IQHandlers in certain plugins).

I favor being spec-compliant by default. If we have plugins that choose not to (which arguably is a bug in those plugins or in the protocol that they implement), then Openfire could facilitate that by having an opt-out mechanism.

Behavior remains the same in 4.8.0-SNAPSHOT:

Dave, as you are very familiar with the core specs, maybe you could elaborate on this.
