In this episode, we're going to talk about spammers, and the people who try to get away with it. Some even have the nerve to try to seek compensation for "loss of business" when we terminate their account due to the abuse reports that start flowing in.
Generally, if someone calls us and asks, "Do you block port 25?", red flags go up, and we give them a fairly standardized answer. We tell them, "No, you are given an IP address when you connect, and there are no filters between that IP and the rest of the world. However, per our terms of service agreement, if you use our service to send out bulk, unsolicited e-mail, and we receive any abuse reports which are tracked back to your account, your account will be terminated immediately, without refund."
Our dial-up lines are set up like many other small ISP's are. We have ISDN PRI lines coming into our facility, terminated into Ascend Max 4048 Remote Access Servers. Those Maxes are plugged into an ethernet switch, one of the ethernet ports on our main border router is also plugged into that switch, and the Maxes use that router as a default gateway. That border router has several dedicated connections to the Internet and there aren't any control lists nor is there any firewalling done on any of those interfaces. Anyone connected to the Maxes has a straight, unfiltered path to the rest of the world.
Our story starts on Monday, February 4th, 2002 when we opened a new account for a man who called and asked the magic question, "Do you block port 25?". After receiving a close adaptation of the statement above by one of our support technicians, he agreed and asked to go ahead and start an account. We happily oblidged and got all of the necessary accounting information. Then he came by our office with a check for the first month, and we activated his account.
A short time later, he called to speak to one of our support technicans and asked why we were blocking him from using port 25. Our technician was puzzled by the question, but assured him that between his modem connection and the outside world, there is nothing on our network that will block him from making connections to anywhere else on port 25.
He must have figured something out, because on February 12, we began receiving abuse reports from SpamCop. After investigating the reports, we determined that the person connected to the IP in which the spam originated was, indeed, this same man who had asked about port 25. Per our Acceptable Use Policy, our abuse technician disabled his account.
The man called to speak to one of our support technicians again to ask why he couldn't get connected to our dial-up lines. After looking into the notes on his account, our technician informed the man that we had received spam abuse reports that originated from that account. The man became outraged and said that he was only e-mailing people who had asked to be e-mailed, and that he had a signed statement from all of them. Our technician explained to him again that we have a zero tolerance on spam, and that since we had received abuse reports, and the account was locked out due to abusive activity, there was nothing that he could do. The man then asked to speak to a manager, so our technican passed the call over to our project manager. Our project manager was on the phone for a while, trying to explain that it's our policy to terminate without refund after receiving abuse reports. The man finally hung up out of frustration, but not before mentioning that five other ISPs have "cut him off for the same reason."
And, there you have it. No wonder there's so much spam going around out there. There are people like this that actually exist in the world who make it happen.
Here are the examples of some of the abuse reports. For the most part, they are un-doctored. We have only removed the portions that would disclose e-mail addresses or names. This is to help keep more spam from being circulated by web spiders which harvest e-mail addresses for spam lists.

Here's another one. The content of the spam is the same, so it was left out, but the report and headers have been left. It looks like person submitting the report left out the e-mail addresses for us.

It doesn't take rocket science to see that these two reports are plainly of spam, even if they do say that they are not unsolicited in the body of the message. I don't care how many folks ask you to send e-mail to them, they're not going to ask you to send them one with "Win $10,000 dummie" in the Subject.
There were several other reports, but they all looked fairly the same, so I'll spare you the details.
The way we determine which one of our customers is sending the unsolicited e-mail is by checking the timestamp in the e-mail from when it originally hit the outgoing e-mail server. We go through the logs and find which account was connected to that dynamic IP at the time the message was originally sent. Here is a copy of that piece of log. We've removed the name of the account and the caller ID phone number to protect the guilty, but it does, indeed, have his account name listed.

He connected at 12:24:33 and disconnected at 16:34:19. The entire time the he was connected, his assigned IP address was 18.104.22.168. This matches the time and the originating IP address that the spam reports show, and yes, we are in GMT -0500.
Here is an example of one of the 46,117 lines of log file. This one shows that the spam was originating from a different IP than above.

We checked through the dial-up logs, and sure enough, it's the same account connected. It looks like in trying to send out all of this data, he flooded himself off of his dial-up connection somewhere in the middle because the time he disconnected was very close to the time that the mail server received the last connection from his IP. In the minute that he was connected, he managed to send out 60 e-mails.

His activity generated 10,053,339 bytes of mail server log file alone. He had a recipient list of 11,681 individual, unique e-mail addresses. A search through the log reveals that his activity generated 11,997 individual messages to be sent, which means that some recipients probably received the spam more than once. Of the 11,997 e-mails that went out, 8,767 were actually delivered to their destination. This all means that potentially, we could receive that many abuse reports and our mail server could be put on blacklists, preventing our customers from sending legitimate e-mail. This is why we call it "abuse" and have zero tolerance for it.
