dont-spam.us

This domain is used as part of a "honeypot" for catching spammers.

There are no valid email addresses in this domain, for sending or for receiving.

If you run a mail server and receive incoming mail which claims to be FROM this domain, you may safely assume that the message is spam, a scam, or some other kind of traffic that you probably don't want on your server.

Note that this only applies to messages claiming to be from the dont-spam.us domain (or any sub-domains). The server hosting this web site IS a legitimate mail server, and sends outbound email for a few dozen other domains. You should not block all mail coming from this machine's IP addresses, unless you believe the server itself has been compromised (and in that case, please contact me and let me know so I can fix it).

If you try to send mail TO this domain, my server will add the IP address from which the message was sent, to an RBL (Realtime Block List), and that IP will no longer be able to send any messages to my server.

If you're a spammer and you're using email addresses in this domain for anything (i.e. sending spam to addresses in this domain, or using addresses in this domain as fake senders to try and bypass other peoples' filters), even after this web page tells you not to use them and why ... you're just stupid and you deserve what you get.

For Spammers and Bots

Here's a list of randomly generated fake email addresses, in this domain. Some spammers use programs that scan the internet, searching for new email addresses to send spam to. I figure if their web crawlers find this page and harvest these email addresses, they'll try to send spam to them. When they do, they'll just be adding their own IP addresses to my blacklist.

Does this work?

I've been "seeding" the spammers' databases with fake addresses like this for over fifteen years, using a few different domains. My mail server receives several hundred attempted messages per day for just this one domain, and looking at the logs it's fairly obvious that almost all of them were randomly generated. As a result, the spammers are currently adding anywhere from 30 to 200 new IPs to my list every day, which means my server is receiving that much less spam.
