Actually, you do have an MX record for goingoncetwice.com:
goingoncetwice.com. MX 10 mail.goingoncetwice.com.

What you don't have is an address record for mail.goingoncetwice.com. The
closest you have is this:
goingoncetwice.com. A 207.246.235.210

Change one of them to match the other. The same problem exists in your
nextnet.com domain:
nextnet.com. MX 10 nextnet.com.
mail.nextnet.com. A 207.246.235.210

Again, change one of these to match the other.

I haven't looked at the rest of your domains. I assume the rest are similar
to the goingoncetwice.com domain.

In case you haven't read DNS and Bind, here's what's going on:
An MX (mail exchanger) record maps a domain name to the server that accepts
mail for that domain. The mail server doesn't have to be in the domain.
However, it does need to have a corresponding A (address) record. So, you
might have the following records, in each the appropriate zone file:
abc.com. MX 10 mail.xyz.com.
xyz.com. MX 10 mail.xyz.com.
mail.xyz.com. A 192.168.0.5

The 10 in the MX records is a preference value. That way you can have
multiple mail servers for a domain (for redundancy, in case one drops off
the net), and they'll use the preference values to figure out which one is
ultimately responsible (it's the one with the lowest preference value).

So in the above example, the first two records are saying that mail for
both abc.com and xyz.com should be sent to mail.xyz.com, which will hold it
until the recipients retrieve it.

The third record translates that name, mail.xyz.com, into an address.

In your specific case, the records might look like this:
goingoncetwice.com. MX 10 mail.nextnet.com.
nextnet.com. MX 10 mail.nextnet.com.
mail.nextnet.com. A 207.246.235.210

Of course, the first record goes in the goingoncetwice.com zone file, and
the second and third go in the nextnet.com zone file.

If you need further explanation, please ask for it.
