Just an FYI: I just migrated DNS for the courier-mta.org domain. The TTL of
the existing records was one day, so it should take a day for everything to
propagate and cut over to DomainDiscover, the new DNS host.
Over the next couple of days, if someone can't find http://www.courier-mta.org,
give me a heads-up. No need to let me know if everything still looks good,
just drop me a line if you're having problems resolving the domain.
