Servers should either store messages, or forward them to the highest online
resource (if the user has one).  I thnk you're thinking about iq stanza's -
which should be rejected if the resource is offline.  So change to iq's and
that should fix the problem.

In an ideal world, you'd never have broken s2s, but it happens.  My guess
would be to send a presence probe if the resource hasn't updated in the last
[x] hours.
