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.
I created an account yesterday, and didn’t receive an email. When trying to log in, nothing happens, but the page receives a 400 error.
You’re right. I’ve tried sending an email and it arrives to my personal server, but gmail outright refuses to even accept it. Will have a look on how to solve it.
Thanks for your reply, so it’s a gmail issue after all :/
