An SPF record is a type of Domain Name Service (DNS) record that identifies which mail servers are permitted to send email on behalf of your domain. The purpose of an SPF record is to prevent spammers from sending messages with forged 'from' addresses at your domain name, and to help your real mail get delivered like it should.
SPF file if you only use our mail server to send mail from your domain name (and nothing else sends email from your domain for you - shopping carts, email marketing, etc)
v=spf1 +a +mx +ip4:18.104.22.168 ~all
You can edit your SPF record by logging into cPanel and clicking on the Advanced Zone Editor tool.
If you use any special services to send email 'from' your domain eg. (from firstname.lastname@example.org), like an email marketing program (like Constant Contact) or a hosted shopping cart (like Mals-e), you should add them to your SPF record to make sure that mail sent by those services is not stopped as spam.
Some common email senders and their SPF settings:
- add include:spf.constantcontact.com
1. Invisible gold
- Make sure to have +a and include:spf1.invisiblegold.com.
