Blocking Spam - The spammers File
As a Solution to the Internet Spam Problem, we have created an
easy and straightforward way to block e-mail to a Virtual Server from specific e-mail addresses and domain names.

# cyberpromo.com (blocks all mail from the hostname "cyberpromo.com")
# firstname.lastname@example.org (blocks mail only from "email@example.com")
