Setting it up can be tedious depending on your needs.

If your mailserver is self-hosted, giving you direct access to the
filesystem, that gives you more options (rsync, Unison, Dovecot dsync,

Even if not, it's still possible using isync, fetchmail, or whatever
(see URL above).

Once the initial sync is performed, though, subsequent syncs should only
need to transmit the difference between the local and remote mailstores,
and therefore should usually be fast and, optionally, automatic.
