More Information About Spfbl Dnsbl

A listing by SPFBL DNSBL indicates that the IP address has been identified as unsuitable for sending email. SPFBL lists IP addresses that have sent spam, as well as IPs that are not configured correctly to send email. SPFBL is a Brazilian blacklist that primarily focuses on reducing the volume of Brazilian spam. It was created in late 2015 and was opened up for use by any MTAs to block spam sources and IPs unsuitable for sending mail.

Spfbl Dnsbl Requires A Manual Delisting Request

This blacklist does support a manual request to remove or delist your IP Address from their database. Please note that removal requests that are submitted without addressing the core problem will likely result in your IP Address or Domain being relisted in that database, which can cause subsequent problems and extended listing periods without release.

Spfbl Dnsbl Accepts Payments Or Donations

This blacklist does support a manual request to remove, delist, or expedite your IP Address from their database upon Payment or Donation of fees to their organization. Please note the following; 1) MxToolBox does not in any way advocate the paying of removal from any blacklists. 2) Removal requests that are submitted without addressing the core problem will likely result in your IP Address being relisted in the database which can cause subsequent problems and extended listing periods without release.
