Properly signed phpmailer emails keep being marked as spam or get rejected

Question

For the past 2 months I have been struggling with the mailserver for a webapplication I'm building. Mails kept being marked as spam or didn't even arrive at a recipient at all.

I started researching this fairly common problem and found out about all the things that come with signing email en authenticating mailservers and so on. I even had to move my domain name to another hosting provider just so I could setup my dkim, spf and dmarc records correctly.

After doing all of this mail-tester gave me the following results:

I figured this would be good enough so I started testing some more. Only to find out that gmail still marks my emails as spam, and outlook (hotmail etc.) still doesn't even receive the email's in any folder.

Since I don't know what to try anymore, i am hopeful someone here would have some suggestions for me.

Thanks in advance!

That mail tester is really basic it doesn't give you a realistic picture of whats really going on.

You should test with the one from Unlock The Inbox . It does well over 400+ different checks, depending on what you have configured.
