A DNS blocklist publishes lists of IP addresses associated with spam. Mail servers often consult them when filtering mail.

Does being listed mean a site is malicious?

Not necessarily. Shared hosting can place many sites behind one address, and listings expire. Investigate before drawing conclusions.

Most lists provide a removal request process. Fix the underlying problem first, then request removal.
