Was DumbMonit überwacht
Every address of a public IPv4 range, up to a /24 (256 addresses), checked against the DNS blocklists of Mail server reputation: Spamhaus ZEN, Barracuda, SpamCop, Mailspike, UCEPROTECT Level 1, PSBL and SpamRATS. The monitor page says how many addresses are listed, on which lists, and gives a direct link to the lookup and removal page of each listing. Useful for the public range of an office, the block a hosting provider gave you, or the addresses your servers send from: a neighbour's compromised machine gets a listing that a stricter receiver may extend to the whole range.
Typischer Einsatz. Every address of a public IPv4 range up to /24 against the DNS blocklists, with delisting links
Beispiele
- Your office's public addresses

Wie die Verbindung läuft
Was Sie brauchen

Kein Konto nötig.
Zu öffnende Netzwerk-Ports

Einrichtungsschritte: Check a public IP range against the blocklists
Enter an IPv4 address or a CIDR range up to /24, for example "198.51.100.0/24".
No API key is needed: leave the credential on No key.
Tick the address 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. Spamhaus PBL lists end-user ranges that should not send mail directly: a listing there only matters for an address that runs a mail server.
