At the moment there is nothing in the server to stop this, but it is
definately an issue that will be addressed as Jabber usage ramps up.

There will most likely be two areas... performance/usage limits to limit
the damage of DOS attacks, and security/preference settings to reduce
unwanted messages.  These will happen before "1.0", but probably not for
the next version or two.
