So, we have a domain that we host on a VPS. We actually changed the MX records so we can use the domain through GMail. Which we check in Outlook. We've had emails running fine for 5 years. They send and receive perfectly. EXCEPT, there's one domain that we can receive emails from. They can receive emails from us, but we never get fresh emails or replies from them... It's not in our spam or junk. They don't get an undeliverable bounce back. It just never makes it. I believe this happened when we were not using GMail's servers as well. A couple years ago we used Outlook and our own MX records/servers for email.
This is a huge problem because the company we can't receive from is our mortgage company. We've called their IT department and they assure us that we are not being blocked and it's not on their end. We've called our VPS company and they assure us the same. We've actually been on TWO VPS's since this started, which further illustrates it's not the VPS's fault. Like I mentioned, I'm 99% sure this happened before we changed our MX records too. So I don't think Gmail is the problem. What else could it possibly be? We send and receive emails all day to various people with no reported issues except from this one company. We've made calls to tech support and they've checked to make sure the domains aren't blacklisted anywhere. We even white listed them on our previous server. Nothing has helped. The domain our emails are at is prellis.com... The one and only domain we can't receive emails from is prospectmtg.com. Like I mentioned, they can receive emails from prelliis.com... Prellis.com just can't receive from them... Ever. They can send to my personal email just fine. They email plenty of people to. They just don't get to prellis.com recipients... What could this possibly be?!? Thanks!
