  We investigate the dynamics of spin in the axially anisotropic
Landau--Lifshitz field theory with a magnetic domain wall initial condition.
Employing the analytic scattering technique, we obtain the exact scattering
data and reconstruct the time-evolved profile. We identify three qualitatively
distinct regimes of spin transport, ranging from ballistic expansion in the
easy-plane regime, absence of transport in the easy-axis regime and
log-modified diffusion for the isotropic interaction. Our results are in
perfect qualitative agreement with those found in the anisotropic quantum
Heisenberg spin-$1/2$ chain, indicating a remarkable classical-quantum
correspondence for macroscopic spin transport.
