Question

Gmail marking all my sent mails as "spam" despite all tests (DKIM, DMARC, SPF) being passed...

So apparently all the emails I am sending from my mail server (Postfix) are being classed as spam by Gmail. Gets me very frustrated as all the tests (DKIM, DMARC, SPF) have been setup correctly and all pass in Gmail. A reverse DNS record is also present and fine. Any advice on what to do next? Or what I might do to fix this mess?

Thanks

Hi, Edward

Did you solve this issue, I am facing the same problem, all seems to be OK but Gmail is still sending to SPAM folder every email from my domain.

Thank you

Hiya @EddieJibson,

That is indeed odd. If you haven’t already, it might be worth signing up for a Gmail Postmaster account at https://gmail.com/postmaster/ - This should allow you to see more Gmail insights into the rating Google has given your domain.

Hope that helps! - Matt.

Hi, @MattIPv4.

Thanks for suggesting. I had already checked this and it’s not blacklisted. All ports are open, too. So, with all this in mind and all those tests passing, you can see why I’m puzzled as what I could do to fix this.

Cheers.

Hiya @EddieJibson,

You can check your IP/domain against the standard email blacklists that most sites use at https://mxtoolbox.com/blacklists.aspx

Let me know if that helps at all! - Matt.

Hello,

I would recommend sending an email to this site here:

https://www.mail-tester.com/

Then check the report it would give you a tone of suggestions on why your emails might be marked as spam. I use this all the time.

Hope that it helps!
