    The value of an SPF record check

    Sender Policy Framework, or SPF, is an email authentication technique that helps protect email senders and recipients from spam, phishing and spoofing. SPF enables receiving mail servers to authenticate whether an email message was sent from an authorized mail server – but only when the domain owner's SPF record is valid.

    Mimecast DMARC Analyzer provides a free SPF record check that can validate an SPF record by simply entering a domain name. Within seconds, you can receive a report that displays your DNS record and parses your SPF record, identifying any problems with it. Mimecast's SPF record check can also validate any updates you applied to your record. It is strongly recommended to carefully test updates with an SPF record check before applying them to a DNS record.

    Heighten SPF effectiveness with DMARC

    The SPF email protocol helps to block email where spammers and scammers send messages that appears to come from a trusted domain. SPF enables the owner of a domain to publish a list of mail servers that are authorized to send mail on its behalf. The list appears in an SPF record in the domain's DNS. When receiving an email, ISPs and mail servers can perform an SPF check to see if the message has been sent from an authorized source. If a message fails the SPF test, it may be blocked or delivered in the spam folder.

    While the SPF protocol is helpful for stopping certain types of email attacks, it is not a comprehensive solution for email security. SPF offers no protection for email that is forwarded, and it can't spot emails where attackers are spoofing only the "from" address – the address that users see in the email header. Additionally, many organizations fail to continuously update their SPF record, making the protocol less effective.

    It's no wonder, then, that many organizations are turning to DMARC (Domain-based Message Authentication, Reporting & Conformance) to improve email security. DMARC builds on SPF as well as the DKIM authentication protocol to tighten security and spot illegitimate email more successfully.

    Despite its advantages, DMARC can be a challenge to deploy and administer successfully. To simplify implementation and management of this powerful protocol, Mimecast offers a 100% SaaS solution that minimizes the cost and complexity of DMARC deployment.

    FAQs: What is an SPF record check?

    What is SPF?

    Sender Policy Framework, or SPF, is a technique for authenticating email that enables the owner of a domain to specify which mail servers or IP addresses are used to send mail. Receiving mail servers can determine whether an inbound email is legitimate or not by comparing the "envelope from" address in the email header to the list of IP addresses published by the domain.

    What is an SPF record?

    An SPF record is a list of authorized mail servers that is published in the Domain Name Service (DNS). When receiving an email, a mail server can check the IP addresses in the SPF record. If the IP address in the email header isn't listed in the SPF record, the email may be considered illegitimate and may be rejected.

    What is an SPF record check?

    An SPF record check is a diagnostic tool that looks up the SPF record for a domain, displays the record and runs tests to uncover any errors within the record that could adversely impact email delivery. Mimecast offers a free SPF record check as well as a free DMARC record check and a free DKIM signature check service.
