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 most Virtual Servers. Each Virtual Server has a ~/etc/spammers file which contains something like the following. # # Simply add the hostnames or email addresses on their own lines below # that you don't want to receive email 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") # # Sources for lists of common rogue spammers and spam sites: # http://www.idot.aol.com/preferredmail/ for AOL's blacklist # http://www.vix.com/spam/rogues.html for Vixie's blacklist # http://www-math.uni-paderborn.de/%7Eaxel/BL/ for Blacklist of Advertisers # # Promote Responsible Net Commerce: Help Stamp Out Spam! # See http://www.vix.com/spam/ for more information # 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 Virtual Server 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 Virtual Server. Connect to your Virtual Server 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 Virtual Server. Run the vnewspammers command: % vnewspammers
