    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?
