Honestly I'm confused why it's returning 553 when it should be
deferring the connection with a temp dns error if a nameserver isn't
reachable. What patch are you using? I've not seen this behavior
with our mail server.
Using bind? Try "ndc reload" instead of restarting the server.
Latest version has a nifty "reconfig" command that only checks for
new/removed zones.
