SpamRats runs four lists, and only one of them means you actually sent spam. The others flag IPs that look like they shouldn't be running a mail server at all.
| List | What It Means | What to Do |
|---|---|---|
| RATS-Dyna | Dynamic IP ranges, like home broadband. | Send mail through your provider's mail server. |
| RATS-NoPtr | IPs with no reverse DNS. | Set a proper reverse DNS (PTR) record for your mail server. |
| RATS-Spam | IPs seen sending spam. | Find and stop the source, then request removal. |
| RATS-Auth | IPs caught guessing email logins. | Look for a compromised machine on your network. |
Look up your IP on SpamRats' removal page, review the result, and submit a removal request. If automatic removal isn't available, SpamRats asks you to use its contact page. If you don't run your own mail server, SpamRats says you shouldn't need to remove anything; talk to your ISP instead.
Generator Labs checks your IPs against hundreds of blacklists and alerts you by email, Slack, SMS, or webhook when a listing appears, with the list name, so you know what to fix. Free for your first host.
Only if you're on RATS-Spam. The other lists are about how your IP is set up.
Home and dynamic IPs are listed by design. Your ISP's mail server handles your mail.
