Here is my senario:
- I have domain say myDomain.com is using google app mail server to send and receive emails
I have a sendMail server deployed on my a cloudServer that I am using to send email campaigns & news letters to my clients ( with from address in head is: info@myDomain.com)
Now when I observe email headers of mails that I sent from my sendMail server I notice
Some of my customers reported that campaign emails are going into spam, when I investigated the problem I found that it can be because of "Received-SPF" is missing.
My question is Where should I setup (in cloudServer DNS OR google app mail DNS) MX, NS, CNAME records or or any other setting that will allow sendMail server to send email that has low risk of being marked as spam.
