Handle Black Lists

Definition: Generally, a blacklist is a list of people or things that have incurred disapproval or suspicion or are to be boycotted or otherwise penalized. Related to e-mail, blacklisted IP addresses will not be allowed to send mail to someone trusting the blacklist. Blacklisted e-mail addresses will not be allowed to send mail to a user or organization. See: DNS-based Spam Databases www.mxes.org/glossary/

Spam and BlackLists

Some of you are adding lots of blacklist entries to your Anti_Spam configuration. Two things:

  1. It's a waste of time
  2. Wrong place to add it.

People sending spam will use a different mail address each time, so yes you can add it as a blacklist entry but the chances are it will never be used ever again (we had 15000+ on a block list and only 2 have ever re-appeared - internally we have stoped using it.

However, there are occasions where you want to block a sender for other reasons than spam. Doing it in the Anti-Spam software is very resource greedy you are better off handling it before it hits the system - block the mail as it appears.

Use the Admin menu:

Add the mail addresses you want to this file one per line.
