Can someone help resolve this?

Rebuilding the mail server resolved the issue.

I removed the SSL for that domain and re installed. Not sure if it helped the cause

Good, good -- those are basic steps to resolving mail issues. Do you also have a PTR (reverse DNS) record with your host? It is a key that legitimizes your server. Also, ARC is going to become a big sticking point soon.
