[jdev] Server rules for handling subscriptions for non-existent users

[Vinod Panicker]

Hi,

It seems that server behaviour for handling presence subscribe stanzas
to non-existent users is undefined in the RFC.  IMO, it should be
silently dropped.

Do give me a bonk on the head if its there in the RFC someplace.  If
not, probably could be added to xmppbis

Also, what about roster set for non-existent users?  If the server
returns an error, it would give away existing account information.

Regards,
Vinod.
