Tip: If you use sendmail on your mailbox server, use a plussed address when subscribing to systems that don't obfuscate your address in their archives. You can then use a procmail recipe to filter stuff using that address to a separate folder, and make it easier to track what archive a spammer is harvesting addresses from. For example:
shiva+fedora_dev_plussed_example@xxxxxxxxxxxxxxx
and intelligent robots can remove everything between + and @ also...
