The rsync daemon protocol on port 873 does not support encryption or
integrity protection, so an rsync daemon over ssh may actually be just
what you need.

Ah.  You have "use chroot = yes".  Most operating systems don't let
unprivileged users call chroot, so that would result in an error.  An
error message should be written to the log file, but it looks like the
log file isn't writable by the "rsync-acct" user either.
