Check one IPv4 address or a list against available DNSBLs before configuring outbound email. Each source gets a separate result.
If an address is listed, use the corresponding operator’s official service: Spamhaus, SpamCop, UCEPROTECT, Barracuda or PSBL. Each operator sets its own removal requirements and timing.
Fix the root cause first: audit outbound SMTP, open relays, compromised accounts, PTR/HELO, SPF, DKIM, DMARC and sending rate.
External DNSBL availability changes. SORBS is not used because the service was decommissioned on June 5, 2024. A DNS resolver error can resemble a clean result, so verify critical findings on the operator’s website.
No. DNSBLs are only one signal; receiving systems may also evaluate the domain, content, authentication and sending history.
