what if the SA plugin had a timeout, and responded with a provisional OK if it hadn't come up with an answer w/in ten sec or so? the received message might have to be thrown out receiver-side or a bounce message generated, but an impatient sender wouldn't time-out. Server sanity might require sending a 421 and closing the pipe after accepting the still-unjudged message to let the plugin decide what to do and not have to maintain valid server state. Would a new plug-in response code, such as OK_SHUTDOWN, be needed to allow plugins to do stuff like that?
