Juno Online Services Inc., an Internet company that has attracted millions of users to its free e-mail service, filed for an initial public offering to raise as much as $86.3 million. Juno is an affiliate of New York-based D.E. Shaw & Co., a brokerage and hedge fund manager. Bringing the online service public in a hot IPO market for Internet companies could be a boon to Shaw, which is selling businesses, including its online brokerage technology unit, in a restructuring after it lost hundreds of millions of dollars in bond trading last year. Juno said its e-mail service, reached with a local call almost anywhere in the U.S., has attracted 6.6 million customers since its 1996 launch.
