How to get delisted from SPFBL — a blacklist focused on SPF authentication failures and spam from IPs with broken SPF records.
Removal Method
Self-service web form after fixing SPF authentication issues
Time to Removal
24-48 hours after submitting removal request.
Overview
SPFBL (dnsbl.spfbl.net) is a DNS-based blacklist that emphasizes SPF (Sender Policy Framework) authentication. It lists IPs that send email failing SPF checks or that are associated with spam. SPFBL is particularly popular in Brazil and Latin America, where it is integrated into many mail server configurations.
Why You Might Be Listed
- 1Your IP is sending email that fails SPF authentication checks
- 2Your SPF record is misconfigured, missing, or too permissive
- 3Spam was detected from your IP, compounded by SPF failures
- 4Your IP is not authorized in the SPF record of the domains it sends mail for
Step-by-Step Removal
Check your listing
Visit spfbl.net/en/dnsbl/ and enter your IP address to check your listing status. SPFBL will show the reason for your listing and your current SPF compliance.
Fix your SPF records
Ensure every domain you send email for has a valid SPF record that includes your sending IP. Use 'include' mechanisms for third-party senders and end your SPF record with '-all' (hard fail) rather than '~all' (soft fail) for better authentication.
Request removal
After fixing your SPF records, visit spfbl.net/en/dnsbl/ and submit a removal request via their web form. Provide your IP and confirm that SPF issues have been resolved.
Validate your fix
Send test emails and check the Authentication-Results headers to confirm SPF is passing. Use tools like mxtoolbox.com to validate your SPF record syntax.

- ●SPF is fundamental to email authentication. If you are listed on SPFBL, your SPF configuration likely needs attention regardless of this specific blacklist.
- ●Avoid using '+all' in SPF records — this authorizes any IP to send as your domain and is a red flag for all spam filters.
- ●If you use multiple email services (e.g., Google Workspace, Mailchimp, transactional email), make sure all of them are included in your SPF record.
