  We theoretically investigate the finite-frequency as well as the
zero-frequency charge-current fluctuations through a noncollinear
single-electron spin-valve transistor in the limit of sequential tunneling. The
system under consideration consists of two tunnel junctions that connect a
small central metallic island to two ferromagnetic leads with noncollinear
magnetization. Due to the spin-dependent tunnel coupling and the
electron-electron interaction on the central electrode an exchange field that
acts on the accumulated island spin is present. We analyze how this
many-particle interaction effect influences the current noise. In detail, we
present that the field leads to a reduction of the sub-Poissonian Fano factor.
