    BUGFIX: GNOME Bug #596027: In Anjal, although invalid mail address warning popup, mail's tab closed automatically
    
    This bug is also reported as Moblin Bug #6108.
    
    This patch depends on an evolution commit (df1f9b3 of evo/master or
    50ffa65 of evo/gnome-2-28), which added a "mail_sent" bit to the
    composer. Now Anjal only close the composer when the mail is sent
    successfully.
    (cherry picked from commit d5624ca231c675c94f75e85a23b3fedd7f111300)
