Improving mail deliverability
I did a test with mail-tester.com on my email sent throught sendy / Amazon SES and I have 7.7/10. Not bad but I would like to reach 10.
The only points which are in orange or red, with my questions, are the following. They all concern SpamAssassin spam filter :
-2.299 (red) URI_NO_WWW_INFO_CGI CGI in .info TLD other than third-level "www"
That's the most important point but I don't understand the issue. Do you know ? Any help is welcome
-0.249 (orange) HEADER_FROM_DIFFERENT_DOMAINS From and EnvelopeFrom 2nd level mail domains are different
Not sure to get this one. Probably one is my domain and the other one is amazon domain as it's using ses. And I don't know if I can improve that.
-0.1 (orange) DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
What do you think about that ? I implemented SPF, DKIM and DMARC so I don't think I can do more. Do you know why it's not green ?
Thanks for your help.
