If your e-mail addresses are listed on your website, you may have received spam messages titled
A bad thing about the group behind this spam operation is that they are unlikely to quit doing it until they physically end up in jail for sending spam messages. Obviously, they are trying to make a living by selling a list of doctors. They change key phrases slightly each time to make sure that you can’t easily use e-mail filters to block their spam messages. And the worst part is that they obtain for free or even purchase e-mail addresses from career e-mail harvesters who are particularly notorious in gathering them from PayPal checkout pages.

So, again, this ‘medical doctor list’ spammer is not going to quit sending spam messages any time soon. If you desire to completely stop them, you may actually try buying the list. Ask them if they allow you to send a payment by wire. In this way, you can get their bank account, through which you can probably see their identity. And you can then contact provincial or federal prosecutor’s office to get them convicted.
But the title of this article is not how to catch or stop the ‘medical doctor list’ spammer. It’s about how to block their spam messages. In order to systematically stop them, you need to see the headers of multiple spam messages from them and find common characteristics. And you need to find out how they send it, by using disposal e-mail accounts (HOTMAIL, GMAIL, Yahoo Mail) or hacking website accounts to access third-party mail servers.

As shown in Screenshot 01-3, we have three spam messages. And Screenshot 04-6 show the headers of those spam messages. They appear to use a different e-mail server each time they send a spam message. But what’s so stupid about this spammer is that they always use the same identity. Delldim5150 is possibly an e-mail username. They use the same one repeatedly.

As long as they keep being dumb, you can use e-mail filters to easily block their ‘medical doctor list’ spam messages. As shown in Screenshot 07, you may have different filters to choose from. So choose what? We want to choose Any Header. And enter Delldim5150 for the key phrase to block. As for destination, common values are discard and fail. So you want to enter fail to have spam messages returned. In this way, hacking victims will be aware of security breach.
Again, we are just trying to block spam messages without destroying the very source. No matter how we block them, they will try to send us more junk messages. And we will keep receiving them unless we send those suckers to jail where they have no access to computers. Cyber criminals… They are dumb but good at creating a lot of social dead weight loss.
