This month Spamhaus' CSS Blocklist reached 8 million active IPs listed for low-reputation email activity! 🎉
Spam activity appears to be shifting toward residential proxies, making up a significant portion of the increase, as emission IPs are constantly changing, with around 500k new IPs added to our lists each day. 📈
Email admins! Use this real-time DNSBL to reduce inbound spam and other malicious email traffic. For optimum filtering, apply at:
➡️ Initial connection – against the connecting IP
➡️ Once email data accepted – check IPs in received chain mail headers and IPs hosting resources in the body (e.g. URLs)
