Hello dear community,
im renting a xyz.de domain from nitrado.net. I’m using the domain with cloudflare for many services that are running on my local homeserver. And now I would like to use it for my website to send Emails for registration and so on. I made the email-server (postfix) work, but my emails only arrive to gmail-Accounts. So all the other provider like outlook are returning the emails.
How do I setup the PTR and SPF Records correctly? Im running out of ideas.
