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) Learn more about this data set here ⤵️ spamhaus.org/blocklists/comb… #Spam #ResidentialProxies #EmailFiltering
