Do not use host spam blocking lists

Have you ever felt that you may be loosing incoming email? It is a bad feeling. Furthermore, if you think the nasty you may be, not answering those emails you never received, but they think you did.

Please, please, please, if you are a sys admin, please, do NOT use host blocking list. While their intention is good, their results may be awful.

There are much better ways to fight spam:

  1. Do not publish your email address in a web page. (Use the "user at provider.com" form)
  2. If you have a domain name, use something like spam shield, to avoid them taking your email from the registers.
  3. Mask email addresses in mailing list archives, if you are the admin. If you are not, avoid writing to a list which does not mask email addresses.
  4. If you are a web admin and email addresses should appear in a web page use SugarPlum
  5. Use safe operating systems like GNU/Linux, as in other unsafe systems there are virus collecting email addresses to spam.
