Was DumbMonit überwacht
A mail domain, or the public address of a mail server, checked against the DNS blocklists that still decide whether mail is delivered: Spamhaus, Barracuda, SpamCop and a few smaller ones. For every list that lists an address, the monitor page gives the list's answer code, its published reason and a direct link to its lookup and removal page. Enter a domain (example.com) and DumbMonit checks the addresses of its MX hosts (A and AAAA records), the addresses of the domain itself, and any Extra addresses you add (an outgoing relay that is not an MX).

Wie die Verbindung läuft
Was Sie brauchen
- Spamhaus DQS key (optional)Only useful if Spamhaus refuses your resolver. A free Spamhaus Data Query Service key (low, non-commercial volumes) makes Spamhaus answer through any resolver, public ones included. It changes nothing for the other lists.
Kein Konto nötig.

Einrichtungsschritte: Check a mail server against the blocklists
Enter the domain you send mail for ("example.com"), or the public IP address the server sends from.
No API key is needed: leave the credential on No key.
Tick the blocklists to query under Blocklists, and add any other DNSBL zone under Custom lists.
If the monitor shows "Spamhaus refuses this resolver", set "Resolver" to your own recursive resolver, or choose the free Spamhaus DQS key as the credential.

Hinweis. A blocklist that does not answer is shown as unknown, never as clean.
