Who Sends Email Spam (by domain extension or website) and How to Block Them!

Spammer's Domains: Where (Online) DO the Spammers Live!
It's easy to see who is sending the spam. Here's how you can stop them.  Why doesn't the government stop them?

Do you receive lots of junk email messages from people you don't know? Offensive porn?  Lottery scams? Junk pushing "male enhancement", deliberately misspelled so your spam filters won't catch them?

 Our studies show that 95% of all spam actually comes from less than a dozen sources.  Of course, the spammers change website domains and domain extensions periodically, so this list is s snapshot from late 2014.  But the point is, create a spam filter that blocks these whenever they appear in a message header, and you will block 95% of all spam.

The first 4 are domain extensions. Almost no person and no reputable company you know uses these. The others are spam generating websites; real or spoofed, it doesn't matter, these are the domains that appear in the spam.

  • .link
  • .mobi
  • .in
  • .co.at
  • arnfam.com
  • dealingits.com
  • top20vip.com
  • xfbxgb.com


If you use Microsoft Outlook, or any other email program (aka, email client) that allows you to create your own filters, you can easily block most spam easily. Just enter the list above into your filter and have it delete or move to a suspect folder any email that contains those phrases in the message header.
