Top 6 Reliable SPF Record Checkers

With malicious actors employing innovative ways to target and infiltrate networks and information systems by introducing malware through phishing and spoofing, organizations need SPF record checkers for their domains to search existing SPF records, validate them, and highlight errors, to be corrected at the earliest. SPF records are crucial as they ensure the authentication of the emails originating from their domain and guarantee delivery.

Email frauds and phishing attacks are increasing by the day. Phishing and spoofing emails have become some of the most common cyber threats that can introduce malware into organizations’ information systems to cause irreparable data breaches. An SPF record helps validate the email’s origins by verifying the associated IP address against the sending domain’s owner credentials. The SPF Record checker searches, displays, and validates the respective SPF record while highlighting errors, if any. An interactive online malware analysis service such as ANY.RUN can be leveraged for dynamic and static research and analysis of most types of threats. At the same time, organizations can connect an SPF Record Checker with ANY.RUN’s malware sandbox to validate the SPF record.

Why SPF records must be validated using a comprehensive SPF record checker

Here are five compelling reasons to validate your website’s SPF records use an SPF record checker.

●  Stops Phishing Attacks: Phishing emails use spoofing to mislead the recipients about the message’s origins. SPF, an email validation system, with the help of an SPF record checker, a diagnostic tool, helps prevent spams by detecting such attempts. Generally, such emails carry fake email sender addresses. SPF records help verify the sender’s IP address and ensure that genuine emails reach the recipient’s inbox. And, when it comes to email frauds and phishing, ANY.RUN’s sandbox can be used to check all suspicious links and emails.

●  Boosts Domain Reputation: SPF record checker validates the SPF record that verifies an IP address with its domain and ensures delivery of emails to the recipient. An SPF policy provides a better trust signal to ISPs and increases the likelihood of genuine emails arriving at the inbox. It also prevents the backscatter of errors and bounces notifications when spammers attempt to abuse the domain. All this helps enhance the domain’s reputation. 

●  Improves Delivery Rate: SPF records add the element of trust to emails and increase the chances of email delivery to the intended recipient. Besides, SPF works with standards like DMARC and DKIM to provide authentication and improve the email delivery rate.

●  Prevents Malware: Cyber adversaries try to spoof a domain name for carrying out phishing and whaling attacks. It could potentially lead to the delivery of ransomware and malware and cause financial loss or fraud. SPF record checker verifies the IP address with its domain and authenticates it. It prevents malicious actors from using the domain to launch their attacks. 

●  Reduces Rejection Rate: SPF records enable the recipient email servers to determine the email’s legitimacy. Thereby, it helps in bringing down the chances of rejection and bounces.

What does an SPF record checker check?

A record checker ensures that a record is valid by checking several parameters. The following are the most important among them.

●  Existence Of The Record: It first confirms that a record exists in the DNS.

●  Multiple Records: Only one SPF record is allowed in the DNS. Hence, it checks if there is more than one record.

●  Maximum Lookups: The number of lookups possible is set to 10. Hence, it checks if it exceeds the limit.

●  PTR Mechanism: It checks if a PTR mechanism is used as it is not recommended to use one.
