The computer server that transmitted and received Hillary    Rodham Clinton's emails  on a private account she used    exclusively for official business when she was secretary of    state  traced back to an Internet service registered to her    family's home in Chappaqua, New York, according to Internet    records reviewed by The Associated Press.  
    The highly unusual practice of a Cabinet-level official    physically running her own email would have given Clinton, the    presumptive Democratic presidential candidate, impressive    control over limiting access to her message archives. It also    would distinguish Clinton's secretive email practices as far    more sophisticated than those of some other politicians,    including Mitt Romney and Sarah Palin, who were caught    conducting official business using free email services operated    by Microsoft Corp. and Yahoo Inc.  
    Most Internet users rely on professional outside companies,    such as Google Inc. or their own employers, for the    behind-the-scenes complexities of managing their email    communications. Government employees generally use servers run    by federal agencies where they work.  
    In most cases, individuals who operate their own email servers    are technical experts or users so concerned about issues of    privacy and surveillance they take matters into their own    hands. It was not immediately clear exactly where Clinton ran    that computer system.  
    Clinton has not described her motivation for using a private    email account  hdr22@clintonemail.com, which traced back to    her own private email server registered under an apparent    pseudonym  for official State Department business.  
    Operating her own server would have afforded Clinton additional    legal opportunities to block government or private subpoenas in    criminal, administrative or civil cases because her lawyers    could object in court before being forced to turn over any    emails. And since the Secret Service was guarding Clinton's    home, an email server there would have been well protected from    theft or a physical hacking.  
    But homemade email servers are generally not as reliable,    secure from hackers or protected from fires or floods as those    in commercial data centers. Those professional facilities    provide monitoring for viruses or hacking attempts, regulated    temperatures, off-site backups, generators in case of power    outages, fire-suppression systems and redundant communications    lines.  
    A spokesman for Clinton did not respond to requests seeking    comment from the AP on Tuesday. Clinton ignored the issue    during a speech Tuesday night at the 30th anniversary gala of    EMILY's List, which works to elect Democratic women who support    abortion rights.  
    It was unclear whom Clinton hired to set up or maintain her    private email server, which the AP traced to a mysterious    identity, Eric Hoteham. That name does not appear in public    records databases, campaign contribution records or Internet    background searches. Hoteham was listed as the customer at    Clinton's $1.7 million home on Old House Lane in Chappaqua in    records registering the Internet address for her email server    since August 2010.  
    The Hoteham personality also is associated with a separate    email server, presidentclinton.com, and a non-functioning    website, wjcoffice.com, all linked to the same residential    Internet account as Mrs. Clinton's email server. The former    president's full name is William Jefferson Clinton.
