Where do I setup my SPF record?
I have a VPS where some of my hosted clients will get email going into spam more often than not.
Here are the results of a test I did on mail-tester.com (my host name and IP changed below just for privacy reasons).
[SPF] server.MY_VPS_HOSTNAME.com does not allow your server XXX.XXX.XX.XX to use ONE_OF_MY_CLIENTS_DOMAIN_NAMES@server.MY_VPS_HOSTNAME.com Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses. What we retained as your current SPF record is: v=spf1 -all It should be changed to: v=spf1 ip4:XXX.XXX.XX.XX ~all
My question is, do I change the SPF record at the registrar where my VPS domain name is registered?
Also, do I have to do this for all my clients domains that I host on that VPS?
Thanks in advance!
