We need your support!
Since October 2003 we have been publishing spamvertized domain and 419 email sender addresses. The lists include domain names and email addresses extracted from spam by jwSpamSpy, our spamfilter. Currently, both lists are amongst the most comprehensive of their kind.
Despite the high volume of additions (about 2000 domains and 2000 email addresses per week) we have maintained an extremely low error rate, a fact we take pride in. This low error rate is due to a conservative blacklisting policy (see here for more details) and manual inspection. We also handle email inquiries about them. This takes time. We can maintain this service with your support:
- We don't currently restrict access to our domain blacklist or 419 sender address lists for filtering email to paying customers because we want to give you a chance to try the data before you pay anything. However, we encourage you to make a voluntary donation or monthly payment (subscription) once you use our data regularly. This applies especially if you are a commercial user (corporate IT department or ISP). We can send you a commercial invoice for your accounting.
- In chosing your donation, please consider the amount of time saved by your user base and support department for every spam email that doesn't get through. If someone is paid as little as $15/hour, then every minute this person does not have to waste on wading though spam will save you 25 cents. Whether you donate 25 cents or $1.00 per user per month ($3-$12 per user per year), it is money well spent. It will give us the resources to provide more anti-spam data more quickly. Rsync access to our data is available on request.
- You are welcome to download plain text files of both lists, but as a courtesy we ask you to leave your name, organization and contact address and to restrict your download intervals to the recommended limits. If possible, also specify the IP address or network range from which you will download (required for Rsync). This allows us to notify you if there are any changes to our service, such as a change in download URL. This is strictly for communications related to use of these data sources.
