Email Connection Refused

While most of my email is received normally, at least one sender consistently receives the following when sending to [anyone]@sunsetbuilderssupply.com:

--- Begin quote ---

Deferred: Connection refused by _dc-mx.e24b260c6872.sunsetbuilderssupply.com.

Warning: message still undelivered after 4 hours

Will keep trying until message is 5 days old

--- End quote ---

The sender is [name withheld]@emeryjensen.com.

Email from [name withheld]@benjaminmoore.com also is not received at sunsetbuilderssupply.com, although I do not have an error message in that case. It may only be coincidence, but both emeryjensen.com and benjaminmoore.com use the domain registrar networksolutions.com and I can find no other correspondents whose mail gets through with that domain registrar.

Hello, 

The first step is to make sure your email DNS is correct. Since you have your nameservers pointing to Cloudflare, I cannot check this for you. Please log into your Cloudflare account and make sure you have all of the DNS from this article:

I should have put that in the original post. Yes, I have checked and all DNS records are correct.

I may have solved the problem. Looking at the DNS records again, the A records for MX were proxied by Cloudflare. I changed the setting from Proxied to DNS Only and a few minutes later, several previously undelivered emails from emeryjensen.com came through to multiple @sunsetbuilderssupply.com addresses. I will continue to monitor but assume the problem is fixed unless I post otherwise. I have no idea why the proxy was apparently blocking only one or a small number of sending domains, while working fine for everyone else.

Previously undelivered mail from BenjaminMoore.com also arrived within a few minutes of changing from Proxied to DNS Only.
