Sender Policy Framework (SPF) is a critical email authentication protocol that prevents unauthorized senders from spoofing your business’s domain. It works by verifying whether the sender’s IP address is approved in your company’s domain DNS records. The protocol significantly lowers the risk of phishing attacks, Spam, and email fraud, protecting brand reputation.
Sendmarc’s manager and flattening features simplify, streamline, and scale the protocol’s management, ensuring your organization’s Domain-based Message Authentication, Reporting, and Conformance (DMARC) compliance is simple and effective.
The protocol protects your business’s domain from spoofing and unauthorized use by authenticating email sources. Domain owners can define which email servers are authorized to send emails on their behalf by publishing a record in their DNS settings.
The protocol is essential because it:
DMARC builds on the protocol (and DomainKeys Identified Mail (DKIM)) to provide full visibility and protection of your company’s domain.
Implementing the standard provides several key benefits:
Enhance your company’s email security effortlessly with Sendmarc. We provide expert assistance, configuration checker tools, and an advanced management platform to allow your organization to easily implement, adjust, and manage the protocol.
Identify all servers authorized to send email from your business’s domain, including its primary email servers, marketing email services, transactional email systems, and third-party senders.
Each of the services will have a unique entry, and Sendmarc’s Knowledgebase includes a large directory of these different entries.
Create a TXT record in the DNS settings with the list of authorized senders. A typical record looks like this:
| Host | Type | Value |
|---|---|---|
| @ | TXT | v=spf1 ip4:192.168.0.1 include:mail.example.com -all |
At Sendmarc, we provide a management feature that offers an easy, secure, and error-proof way to manage a record.
After publishing a record, test it to ensure it’s functioning correctly. DMARC reporting will show if the protocol is authenticating all the required services. Your company can also use Sendmarc’s lookup and header analyzer tools to validate that its record is correctly configured.
An SPF record is a TXT record published in your company’s domain DNS settings that lists all the email servers authorized to send messages on behalf of a domain.
An SPF fail means that the email was sent from a server that wasn’t listed in the domain’s record. The receiving server might reject the message, mark it as Spam, or handle it based on the domain’s policy.
Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are complementary email authentication protocols that enhance email security.
SPF verifies the sender’s IP address to confirm it’s authorized to send emails on behalf of a domain. DKIM adds a digital signature to emails to ensure the communication’s integrity and authenticity. DMARC builds on the two protocols by specifying how unauthenticated emails should be handled and providing reporting on email traffic and failed authentication attempts.
Yes, the Sender Policy Framework (SPF) can improve email deliverability by helping recipient servers distinguish legitimate emails from Spam or fraudulent messages. Properly configured records reduce the chances of your organization’s emails being marked as Spam or rejected.
