At a glance (not thorough inspection) your config looked OK. Expire
time of 100 days seems a bit long.
When I nslookup MX for your domain, I get the addr of your new
server "galley", so no apparent problem there (although I see from a
follow-up post that some folks are getting MX = otto, and *that* is
your problem in a nutshell).
If otto is no longer providing any services to the outside world,
how about just indicating via DNS that otto is CNAME to galley?
