Hi, I'm trying to finish a scripts to manage newsletter from a website but I encountered a strange weird stuff just at the end.
Basically when I send emails everything seem to be alright. I sent 5 email. 3 of them was received perfectly but the other 2 not. Just empty. These email that read as empty the email I sent are @gmail and @hotmail.
So I had a look at the various headers.
In Gmail I got this:
Received-SPF: neutral (google.com: 220.127.116.11 is neither permitted nor denied by best guess record for domain of email@example.com) client-ip=18.104.22.168; Authentication-Results: mx.google.com; spf=neutral (google.com: 22.214.171.124 is neither permitted nor denied by best guess record for domain of firstname.lastname@example.org) email@example.com
And in Hotmail this:
Authentication-Results: hotmail.com; sender-id=temperror (sender IP is 126.96.36.199) firstname.lastname@example.org; dkim=none header.d=perilpoliclinico.org; x-hmca=none
Could be the problem related to this? If yes what I can do? I had a look googling but seem that all this is managed server-side...
Thanks for help.
