You are using a non-existant domain name? That is a problem.

Other email providers will reject your messages if they come from a non-existant domain name.

Also, you have to actually have a domain name to setup SFP and DKIM on the domain name.

Are you using your own mail server? You can look at the mail logs. Do you have DKIM and SPF setup on the email domain? If not, that is a problem.

What do you mean that you removed the domain name? Are you sending email that has a “from” address that is using a non-existant domain name, because you removed the domain name?
