This instructional article will demonstrate the Exclaimer configuration process of Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) Signatures to ensure Exclaimer passes the DMARC alignment check and eliminates spam from your domain, and increases security.
The SPF record identifies the mail servers and domains that are allowed to send email on behalf of your domain. The DKIM record, on the other hand, is a specially formatted DNS TXT record that stores the public key the receiving mail server will use to verify a message’s signature. These email authentication methods will be used to prove to ISPs and mail services that senders are truly authorized to send email from a particular domain and are a way of verifying your email sending server is sending emails through your domain.
The process of configuring SPF
In order to authenticate Exclaimer on SPF, please follow these steps:
- Login and head to your DNS Zone provider
- Create a new TXT record
- Input the DNS name as @ or your domain name
- Input the DNS value as v=spf1 include:spf.<region code>.exclaimer.net ~all
Important Note: Please make sure to replace <region code> with your region code based on your Exclaimer subscription.
To find your region, please follow steps below:
- Head to your Exclaimer portal
- Head to Subscription > Manage
- Under Subscription details, locate Server to view your region
- Save the record
- Wait up to 72 hours to allow your DNS to process the changes
The screenshot below will show you an example of the SPF record. We’ll be using CloudFlare for this example. In this example, we have used UAE as the region code.
Important Note: Each domain must have only one SPF TXT Record. If you have multiple SPF Records, SPF will return a PermError.
If you are using multiple IPs, ESPs, Third-Party services for your various email strategies, you should include them in a single SPF Record.
E.g v=spf1 ip4:220.127.116.11 include:spf.UAE.exclaimer.net include:thirdpartyservice.com ~all
