[JDEV] Subscriptions to non-existent addresses

I don't know how to test if a JID exists, but maybe I can help on the
mechanics of subscription.
Are you talking specifically about subscribing to a non-existent user on
a *different server* than yours, or do you also mean non-existent users
on *your server*?
When you subscribe to a user at your local server who doesn't exist, the
-send you a roster change for that item with ask=subscribe
-send you a presence packet with type=unavailable and status "Not Found"
You don't receive any errors in this case, because it's all handled by
the subscription mechanism through roster and presence packets.

I let my users add contacts but if the reciever never gets their subscription request, the roster item (with an ask=subscribe attribute) remains on their roster indefinitely. I know an error is caused when the packet is bounced back to the server but I don't know if or where this is passed back to the jabberbeans server-side stuff (highly technical term there).
