This is a new domain on an IP that was fairly recently assigned to it. All main email providers blacklist anything that is not gmail, outlook or aws by default. Nothing I can do about it, other than becoming part of the problem and paying them to host this instance’s email.
No worries at all. I’m patient :). As a former sysadmin and current Cloud Systems Architect, I understand. I’m going to migrate one of my domains off of Gmail to a new host to trial it and I’ll try using that email once I get that done. Thanks for hosting this because I don’t have the time to currently. :)
