postfix - Mail is marked as spam although SPF and DKIM pass


  • I have configured Postfix to send mail from a dedicated server hosted let's on IP X.X.X.X and domain name example.com.


  • DKIM, SPF always pass when I send mail locally from that host but still ends up in Spam folder (Gmail, Hotmail).


  • I've also properly configured the Reverse DNS of said server.


  • Here is the SPF record I'm using in case you need it : v=spf1 ip4:X.X.X.X -all and the mail header received from Hotmail and Gmail



  • I made sure the IP was not blacklisted anywhere using mxtoolbox.com




What else do I need to check ? Thanks in advance !
