What is clvSmtpAlgDnsBlMatched?
This gauge counts the SMTP sessions that were found to match an entry on the named DNS blacklist, meaning the sending host's IP was listed as a known spam source. Administrators use this to gauge how much incoming mail traffic originates from senders already flagged by that external reputation service. For example, a high match count against a specific DNSBL entry would justify keeping that blacklist active in the SMTP ALG's spam-checking chain.
