![]() ![]() Email spoofing is sending emails from a fake email address or domain to impersonate someone else. The Sender Policy Framework (SPF) is an email authentication protocol that helps protect email by preventing email spoofing. How Does the Sender Policy Framework Protect Email? Enter the domain name in the box and click “Check SPF.” You'll receive all lookup and check results for that domain momentarily.Īlternatively, you can check the SPF records manually by running the command “nslookup -type=txt” followed by the domain name in a command prompt. It’s easy simply use EasyDMARC’s free SPF Record Checker tool. The record doesn’t contain “10 DNS lookup” error.The IP addresses of the sources are correct.How Does the SPF Record Checker Help?ĮasyDMARC’s SPF Record Checker helps to ensure that: SPF Lookup is a critical security measure to prevent spoofing and differentiate between legitimate and fraudulent sources. If the IP address does not match, then the email is considered to be from a fraudulent sender. It involves performing a DNS lookup of the domain the sender claims to be from and verifying that the sender's IP address is listed in the SPF record for that domain. SPF Lookup verifies the sender's identity when an email is sent out. It checks for correct syntax and other issues, such as missing nameservers, invalid or missing IP addresses, and incorrect TXT records. What is EasyDMARC's SPF Record Checker and Lookup Tool?ĮasyDMARC’s SPF Checker lets you verify if an SPF record exists on a domain’s DNS and if it’s deployed correctly. Setting an SPF record allows you to specify which IP addresses are allowed to send emails on behalf of your domain, and any emails sent from an IP address not listed in the record will be flagged as suspicious. ![]() Most companies and individuals use SPF records to prevent spoofing and enhance email security and deliverability.Īnother reason for setting up an SPF record is to help prevent your domain from being used by spammers to send out fraudulent emails that appear to come from your domain. The SPF record protects a company's domain from spoofing while improving its sender reputation with MBPs (Mailbox Providers) such as Google, Microsoft, Verizon, etc. If SPF passes, the email under question is authenticated and delivered to the recipient's mailbox. This record lists all mail servers authorized to send emails on behalf of that domain. SPF authentication works by setting a special DNS record for a domain. When an email is sent, the receiving server checks the sender’s return-path address and verifies if the domain in use has a valid SPF record. Depending on the qualifiers used (~, +, -, ?), this mechanism indicates how the recipient should treat emails from non-authorized sources. It should be placed at the end of the SPF record. Listing all your sending sources under this tag lets the recipient know that you verify all the added domains/subdomains as legitimate sources.Īll is a required tag. The include tag is of top importance for a correct SPF record. The exists tag checks whether an A record exists or not on the mentioned domain. It's a "not recommended" tag as per RFC 7208, because it spends too many DNS lookups. The PTR tag prompts a PTR check for client IP hostname(s). If left unspecified, it takes the value of the current domain. The MX record tag checks the MX record of the mail server(s). ![]() ![]() The A record tag allows the SPF to validate the sender by the domain name's IP address. This tag should include all the IPv6 addresses that are allowed to send emails on behalf of the domain. This tag should include all the IPv4 addresses that are allowed to send emails on behalf of the domain. If it's incorrect or the tag is missing, the SPF record will be ignored. ![]()
