I hadn't noticed it but all the records in the response to a request for
the MX for tmomail.net have a TTL of 60 seconds, that's the MX record,
the NS authority record and the additional A record. The names in the
delegation NS records for for tmomail.net are different from the
authoritative ones, though they seem to be the same servers. There's
considerable opportunity there for things to go wrong, though it all
seems to work fine from here.
