The lists are updated unfrequented. The date-time shows the last time, a cached version of the list was updated.
Yes. The service is free to use. You can access the lists by simple a GET-Request. The lists are stored in a few different file-types. An specific API is not available at the moment.
Create an account and become a part of our community. On that way you can make sure, that the lists are up-to-date. Also we decided, that anonymous uploads are not processed automatically. We have to check the files manually.
The idea of this service is to provide a list of fishy email-addresses, domains and top-level-domains. If you own a domain, please check, if there is any problem with your mailserver. Use mxtoolbox.com to check your mailserver. If you are sure, that your mailserver isn't fishy, please contact us. With a user-account, you can comment on the data.
That's not good. Please make sure, that your mail-account (or perhaps mailserver?) isn't compromised. If you are sure, that your mail-account isn't compromised, please contact us.
Fishy means, that something is suspicious. In this case, the lists are about suspicious email-addresses, domains and top-level-domains.
That means, if a tld, domain or email is marked as whitelisted, greylisted or blacklisted.
Whitelisted means, that the email-address, domain or top-level-domain is not suspicious. Of course, there is no guarantee, that the data is correct. But you should not block whitelisted data.
Blacklisted means, that the email-address, domain or top-level-domain is suspicious. You should block blacklisted data.
Greylisted means, that the email-address, domain or top-level-domain is suspicious. You should check the data and decide, if you want to block it.
We offer the blacklist and greylist. The lists are available in different file-types. You can download the lists as txt, xml or json.
