The domain is cookephoto.com

Why does mail.metron.com have MX records?

Normally, in my experience, the actual mail server doesn't have MX records as such, but….
Just seems 0dd.

Also, you say …

At the time of the transaction, nothing special was happening here, ...

Was anything strange happening with any of the DNS records for any of these domains in the past two days?

Aloha,
