I subscribe to both the free Dynamic DNS service and the paid Email Store/Forward service.

I thought I had everything setup correctly because some companies are able to send me email (Google, Amazon, etc.) but it seems I am not getting all of my email. For instance I cannot get email from Home Depot. If I send myself test emails from gmail, they can go through. If I send myself email from my work email I get the following response:

5.1.2 - Bad destination host 'DNS Hard Error looking up (MX): all A records of the domain's MX records are invalid"

Why are some senders able to send email to me and others cannot?
