Spam Fighting Toolkit
by Ralph Tegtmeier
Fighting the never ending tide of spam mail can turn into a very frustrating experience if you don’t know the real tricks of the trade. After all, there’s a whole lot more to it than simply responding to a (usually bogus) From: address with a peevish complaint!
Here’s a fairly extensive overview of resources that will aid you in effectively combatting unsolicited email, showing you the possibilities (and, alas, the limits!) of your endeavor.
General resources
The Spamhaus Project features a database tracks known Spam Gangs, Spam Support Services and the providers who keep organized spamming alive by knowingly hosting stealth spamming services on their networks. An extensive set of databases allows for tracking of established spam outfits, including statistics, etc. https://www.spamhaus.org/
Look up this list of established spambots: https://mosa.unity.ncsu.edu/brabec/antispam.html
Resources for header reading are listed at the Forum for Responsible and Ethical E-mail (some broken links, though): https://www.spamfree.org/resources/header_reading.html
Some spambot harrassment programs are listed here: https://www.turnstep.com/Spambot/harassment.html
Spam.abuse.net calls for spam boycots and offers lots of information an spam prevention legislation, and more. https://spam.abuse.net/ > Read their useful guide titled “How To Complain To The Spammer’s Provider” at: https://spam.abuse.net/howtocomplain.html
Mail forwarding services
Protect your mail box with disposable email addresses by signing up with Sneakemail: this service forwards everything to your regular box without disclosing your real address. If you find your Sneakemail address is being abused, you can simply delete it. Plus, it will help you track down businesses that flog your address to third party marketers. Neat. https://sneakemail.com/
Free email forwarding claiming to sport the net’s best anti-spam filters can be found at Despammed.com. Basically, it works as a remote spam filter. (That’s why they term themselves a “mail filtration service”.) https://www.despammed.com/
Spamex takes a similar approach, offering disposable email addresses as a measure to counter spam. It doesn’t bother with sophisticated spam filters, though – the minute your Spamex address receives spam, simply nuke it and get a new one. You can also fit their log in box link into your web browser’s links bar for facilitated access. Their slogan is noteworthy, too: “Because Sending You Email is a Privilege Not a Right!” https://www.spamex.com/
One of the best known anti-spam forwarders is Spammotel (what a name!) which also offers a pretty sophisticated, award winning plug-in for your email client, allowing you to keep track of whom you have given which email address of yours. This, of course, makes it dead easy to test web sites’ privacy policy. Moreover, it makes for a great tool to help you organize the e-mail you actually do want to receive. (Windows only.) https://www.spammotel.com/
Mail Abuse Prevention System LLC offers a commercial spam protection forwarding service at: https://stop.mail-abuse.org/
Spam filters
Webmasters running their own mail server may be interested in The MAPS Relay Spam Stopper, a queryable DNS-based database of spam-relaying mail servers. You can configure your server to utilize their list if you want to refuse mail from these types of servers. https://work-rss.mail-abuse.org/rss/
The same site offers the Realtime Blackhole List (RBL). This is a system for creating intentional network outages (“blackholes”) for the purpose of limiting the transport of known-to-be-unwanted mass e-mail. The RBL is a subscription-only system, working in such a manner that no one is denied connectivity to a non-RBLSM-subscriber. https://mail-abuse.org/rbl/
Reporting spam
This spam complaint primer spells it all out as it is and offers a sample complaint covering every important aspect of reporting spam to get spammers’ accounts and web sites terminated. ttp://combat.uxn.com/tracing.html
The all-time classic to report spam to is the not-for-profit Mail Abuse Prevention System LLC. https://mail-abuse.org/
The Network Abuse Clearinghouse is a complaint service that will forward your spam complaints to the culprits flooding your mail box. https://www.abuse.net/
The MMF Hall of Humiliation takes the approach of ridicule to combat spammers. Lots of parodies and spoofs of obnoxious unsolicited commercial emails, and more. Still, it has a very serious background, informing in detail about fraud indictments and offering rudimentary legal analysis of spam scams. https://ga.to/mmf/
This site offers monthly case studies of reporting spam and lists successes. You’ll see that while it’s quite an uphill battle, it can be done. https://www.obliquity.com/computer/spambait/
Reporting Tools
Some abuse reporting tools are listed here: https://www.abuse.net/tools.html
As for anything on the net, there’s a fitting mailing list available for people interested in software tools that detect and process unsolicited bulk e-mail: https://www.abuse.net/spamtools.html
Proactive Strategies
UXN Spam Combat offers a nice one-page form aggregating all the tools you need to solve the spam problem, ranging from NSlookup and Trace Routing to Pings, decoding of obfuscated web URLs, etc. Very useful. https://combat.uxn.com/
Uni-encoding the email addresses displayed on your web site is still a very efficient method of thwaring email address harvesters or extractor bots: https://fantomaster.com/famshield0.html
This page offers you tools to “poison” the spambots with by feeding them tons of invalid email addresses. While this admittedly places some strain on bandwidth and system resources, it’s also pretty easy to crash a spammer’s system this way – ah, sweet revenge! https://fantomaster.com/faantispamtip2.html
Many spammers are now offering their pathetic wares not via the internet but offline, preferably using toll free numbers. This article outlines a strategy on where and how to hit them hard – in their pockets! https://fantomaster.com/faantispamtip3.html
Probably the most effective method of prevention is blocking spammers and their harvester bots from your web site altogether. This tip expounds the strategy to pursue. https://fantomaster.com/faantispamtip4.html
The Coalition Against Unsolicited Commercial Email (CAUCE) is an international organization promoting anti-spam legislation. https://www.cauce.org/ They also publish “True Tales of Spam” here, where you may see your own story featured some day if you wish tp submit it: https://www.cauce.org/tales/index.shtml
