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.
NOTE: The access File,
which offers more options and fliexibility, is now available on all Virtual Private Servers.
Each Virtual Server has a ~/etc/spammers file which contains something like the following.
#
# Simply add the hostnames or e-mail addresses on their own lines below
# that you don't want to receive e-mail from
# (lines, like this one, starting with "#" are comments; comments are good)
# Examples:
# cyberpromo.com (blocks all mail from the hostname "cyberpromo.com")
# spammer@aol.com (blocks mail only from "spammer@aol.com")
#

spammer@aol.com
cyberpromo.com
Lines that begin with "#" are comments. Other lines contain e-mail addresses or domain names that
are blocked. If the VPS is configured as above, all e-mail with spammer@aol.com or
cyberpromo.com in the "From:" line of the header is blocked.
Usage
You can configure e-mail blocking during a Telnet/SSH session with your VPS. Connect to your VPS via
Telnet or SSH and do the following.
- Add the e-mail addresses or domain names you wish to bock to the ~/etc/spammers file. You can do
this by either downloading the file to your PC, and then uploading the file after making the additions, or
using a text editor, like pico, while connected to your VPS.
- Run the vnewspammers command:
% vnewspammers
