Habeas Sender Warranted Email was an unconventional attempt to fight email spam. It is apparently defunct.
It used a so-called Habeas Warrant Mark, which was a set of email headers containing a copyrighted haiku, and various trademarks. Non-spam emails were authorized to include the Warrant Mark in their headers, but any spammers who distributed the Warrant Mark would be added to a blacklist. Spam filtering software could utilize the blacklist, and/or judge an email containing the Warrant Mark as unlikely to be spam. Legal challenges to the blacklist would be risky, because Habeas could countersue the spammer for intellectual property infringement.
[edit] Format
The first few lines of the Warrant Mark contain the haiku. The remaining lines are reproduced below.
... X-Habeas-SWE-5: Sender Warranted Email (SWE) (tm). The sender of this X-Habeas-SWE-6: email in exchange for a license for this Habeas X-Habeas-SWE-7: warrant mark warrants that this is a Habeas Compliant X-Habeas-SWE-8: Message (HCM) and not spam. Please report use of this X-Habeas-SWE-9: mark in spam to <http://www.habeas.com/report/>.
