"As first reported in August, Yahoo! is providing its email
encryption option through a deal with Zixit, a Dallas-based email
encryption firm. Yahoo! will rout encrypted email through Zixit's
SecureDelivery.com Web site. Yahoo! and Zixit representatives
declined to comment on the public availability of the service and
would not say whether it was an across-the-board launch or a
temporary test." From ZDCOUK.
