[Exim] FW: Integrating SpamAssasin with Exim 4.24-4

I need advise on how best to integrate SpamAssasin with exim 4.24-4
running on FreeBSD 4.9.

I have already installed SpamAssassin 2.61 and starting it with spamd

I had edited my exim configure file with these entries, but was
unsuccessful.

........................
spamcheck_router:
        no_verify
        check_local_user
        # When to scan a message :
        # - it isn't already flagged as spam
        # - it isn't already scanned
        condition = "${if and { {!def:h_X-Spam-Flag:} {!eq
{$received_protocol}{spam-scadriver = accept
        transport = spamcheck
# SpamAssassin
spamcheck:
        driver = pipe
        command = /usr/local/bin/exim -oMr spam-scanned -bS
        use_bsmtp = true
        transport_filter = /usr/local/bin/spamd
        home_directory = "/tmp"
        current_directory = "/tmp" ...................................

Any help is appreciated.

Thanks.
