How do I create an SPF record and where do I add this?
You can create an SPF record through the following wizard.
We cannot create this for you because we do not know the parameters. Once your SPF record created you add it to the DNS of your domain as a TXT record.
Below you will find an example of a possible SPF result: mydomain.com.
v=spf1 mx ip4:22.214.171.124/25 ip4:126.96.36.199/25 ip4:188.8.131.52/24 ip4:184.108.40.206 ip4:220.127.116.11/32 include:abcd.com include:hostbasket.com -all:86400
But it might be shorter e.g.: v=spf1 a -all
The result depends on the parameters you indicate when creating the record.
