Tony Svanstrom, on SpamAssassin-talk, noted this US patent: http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=/netahtml/PTO/search-adv.html&r=62&f=G&l=50&d=PG01&s1=spam&p=2&OS=haiku&RS=spam
Method of anti-spam Abstract A method of anti-spam is to set an optional trustcode, or a trustlist, or at least a trustweb based on online mail delivery at a recipient's e-mail address. A mail sender is compelled at the first time to deliver a mail by way of: taking the way of "Visiting trustweb and sending online", or enclosing the recipient's trustcode in the mail and sending in another way other than the mentioned. After the sender's e-mail address has been stored automatically in the recipient's trustlist, the sender may send mails to the same recipient in whatever the ways feasible. Sounds a lot like TMDA to me. :( Filing date is July 26, 2001, granted May 16, 2002. TMDAers, have you seen this before? I'd presume TMDA is prior art, but still, it could be troublesome... --j. _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
