Blacklisting email spammer's domain step by step
Help us get ride of abusive spammers

 1:05 pm on May 29, 2006 (gmt 0)

Is there some spammers that will send you spam forever no matter what you do, they choose to use your time to send you their garbage you like it or not. I tried spamcop and really don't notice any improvement. So perhaps an experienced webmaster can provide a step by step guide to blacklist a spammer domain.
I'm pretty that will be very appreciated.

In one of my cases I find the spammer uses a free webmail reply email adress, and puts the real domain in spam body.

Step 1) I Went to spam message, extracted the full header, went to spamcop, reported the spam.

Step 2) I Went to real spammer website and made a whois. So I guess I have some valuable information there.

3) How to use that information to blacklist or take other actions against the spammer? Perhaps you may help...

With the whois information, find out their registrar and file a complaint with them.

Some of them are rather strict with exception of afew of the spammer's favorite (a notorious french registrar and most of the korean and chinese registrars) that will just ignore your complaint.

But the most egregious spammers, unfortunately, move their domains, IP addresses and servers faster than any blacklist can keep up with them. There was an article in Wired a year or so back that detailed the worst of the bunch -- and unfortunately a very small number of spammers accounts for a huge percentage of spam.

These steps, however, may have some effect on the minor leaguers.

The best thing to do is install some good spam filtering software and forget about it (assuming you're not getting thousands of junk messages per day). I get several dozen spam messages per day and the SpamBayes Outlook plugin handles it all pretty much flawlessly.

I realize that wouldn't work for the folks who get tens of thousands of spam messages every day of the year, but for the average case, it should work.

Thanks tester. And that's not the spirit MatthewHSE.

The real issue is that your spam complaints can get ip ranges blacklisted.. Then when the spammer moves on in a few days / weeks, and some new guy comes in, they end up blacklisted through no fault of their own..

We had to switch co-location facilities because it was easier than continually fighting for new IP blocks that were clean when we needed more space..

I understand the hatred for spam.. I pay for it every day with more that 60% of the mail we handle is spam.. But the "blackist" has become one of the least effective tools available.. And it tends to do more harm than good when the process to get "off" can be so cumbersome..
