Listed on SpamRats? Find Your List First

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.

The Four SpamRats Lists

ListWhat It MeansWhat to Do
RATS-DynaDynamic IP ranges, like home broadband.Send mail through your provider's mail server.
RATS-NoPtrIPs with no reverse DNS.Set a proper reverse DNS (PTR) record for your mail server.
RATS-SpamIPs seen sending spam.Find and stop the source, then request removal.
RATS-AuthIPs caught guessing email logins.Look for a compromised machine on your network.

How to Request Removal

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.

Did I send spam if I'm on SpamRats?

Only if you're on RATS-Spam. The other lists are about how your IP is set up.

I don't run a mail server. Why am I listed?

Home and dynamic IPs are listed by design. Your ISP's mail server handles your mail.
