check_mx_reputation

Active

declared in 3.29.5

Check whether the mail server (MX) IP addresses are listed on spam blocklists (Spamhaus, Barracuda, SORBS, and other RBLs). Also verifies reverse DNS for MX hosts. Use when you want to know if your mail server IP is blacklisted, or if your MX is on any blocklist — distinct from check_rbl which checks a specific IP directly.
