spamhoneypot.com

Okay, so I recently registered spamhoneypot.com to implement the email harvesting tracker that I was thinking about in an earlier blog.

So here the idea. I’m going to put an email address that contains the encrypted IP address of every visitor on a few websites. This will have the IP address as the user name and the domain will be @spamhoneypot.com

The domain name should be enough for anyone who is paying attention to this lists to not send spam to it, but I suspect that we will see quite a few that simply don’t care.

Once I have this setup I will dump all email into a catch all email box and then catalog each email that come in. Simple I will never send an email out from any of these addresses that would mean that all of the email coming into this domain will be from email harvesters or virus.

My plan is to publish a list of the IP addresses and the source for all the spam messages that I receive from each IP.

Might even make an XML feed or RBL style DNS lookup to see if the IP addresses are known to run harvesters for spam.

Real-time Black-hole Lists

Real-time Black-hole Lists (RBL) are lists of email servers that are known to send spam message through them. Each RLB is run with slightly different criteria and they often have multiple lists that are maintained.

The nice thing about RBLs is that most email servers or anti spam software can use RBLs to identify the IP address of the server that is sending the message and then deny the connection based on the results from the RBL.

In many cases this can reduce the amount of spam a domain is receiving by as much as half with this one simple addition to your spam arsenal.
