If your emails keep going to people’s “Junk” or “Spam” folders on either GMAIL or HOTMAIL this is how to fix it:

GMAIL, HOTMAIL and many other public email systems use Sender Policy Framework (SPF) to recognize legit senders.

If you do not have a valid SPF Record in place, your emails won’t pass the security check and will me marked as SPAM.


1. You need to access your Hosting Control Panel, where the domain in question is hosted. In our case we use cPanel.


2. Find DNS Zone Editor icon (either Simple or Advanced)


3. Chose the domain you want to add the records to and add the following details



v=spf1 ip4:ipaddress/24 -all

v=spf1 a mx ~all

v=spf1 +a +mx +ip4:ipaddress ?all


First option is to use the public ip address /24 in that subnet

Second option uses the server FQDN no matter what the IP is

Third option uses the public ip address regardles of subnets


Second option us usually the most correct option since it uses a FQDN regardles of it’s public IP address..


Hope this helps 🙂
