How to Set Up/Modify SPF for GoDaddy
The following description addresses how to update a Domain Name Service (DNS) record to use SPF with your custom domain in GoDaddy.
To utilize a custom domain, the GoDaddy provider requires an SPF TXT record be added to the DNS record. This TXT record is then used by DNS to recognize email servers allowed to send messages on behalf of your custom/third-party domain. To determine whether a correspondence from the specified domain comes from an authorized messaging server, the recipient system relies on the implemented SPF TXT record. At that point, the message is either accepted, quarantined, or rejected by the email receiving system.
To implement SPF authentication for your domain, you will need access to your DNS records in the domain hosting account. Important: If you already have an SPF record, then you should modify that existing record. You must not have more than one SPF record.
For convenience, be sure to log in to your GoDaddy account to verify your domain and copy your TXT records. GoDaddy utilizes an include mechanism during the set-up process. For example, the following scenario is the most common and would pass SPF:
v=spf1 include:spf.em.secureserver.net ~all
If you send email from IP 1.2.3.4 for the domain “yourcompany.com” and that domain’s SPF record includes infusionmail.com and the IP address passes the SPF record, this mechanism will pass.
As mentioned, if you already have an SPF record set up (and because only one SPF record is allowed per domain), you can simply add a reference to GoDaddy to it. For example, instead of having two separate records, combine them into one:
v=spf1 include:mydomain.com include: spf.em.secureserver.net ~all
How to Set Up/Modify DKIM for GoDaddy
GoDaddy allows DKIM authentication. Email service providers that support DKIM check inbound email to verify whether an organization that claimed to have signed a message actually did.
As a user of this outbound email provider, GoDaddy customers are afforded DKIM signing because it supports that mechanism. Overall, this GoDaddy product provides the beneficial component of DKIM signing that results in a streamlined process.
