"v=spf1 +a +mx +include:spf.email-hosting.net.au ~all"
If you have an existing SPF record, you will need to edit it to add our SPF settings. Here is an example of an existing SPF record that doesn’t include our SPF information: "v=spf1 +a +mx +ip4:123.456.789.000 +include:mail.domain.com ~all"
And here is how you’d add our SPF settings to that existing record: "v=spf1 +a +mx +ip4:123.456.789.000 +include:mail.domain.com +include:spf.email-hosting.net.au ~all"
