That frequently just means they've subscribed to one of the monitoring
services that notifies you if your IPs have turned up on any DNSBL the
monitoring service has ever heard of, sometimes including ones that have
been shut down, domain snatched up by speculators, and wildcard A record
installed pointing at an ads landing page.

If they're not mail servers, how is the DNSBL listing impacting them
(assuming anyone even uses spamrats)?
