I'm not sure if it's related, but I saw a similar problem with the domain
hilarious.com owned by mail.com. The domain has existed for years but mail
from my hilarious.com address, for a short time, was being rejected by web
servers with the same error. Then a few minutes later it was working. Tested
on my RaQ and on another unrelated server. Both couldn't find hilarious.com
in the DNS.
