[Exim] sa-exim

Hi all,

How can build sa-exim for exim-4.24 ?
I try :
make
cp sa-exim-3.1/accept.so /usr/local/exim/bin/
cp sa-exim-3.1/sa-exim-3.1.so /usr/local/exim/bin/

And in the exim.conf I added the line :s
local_scan_path = /usr/local/exim/bin/accept.so
local_scan_path = /usr/local/exim/bin/sa-exim.so

When I start exim I receive the error :
Starting exim daemon ...
2003-10-10 15:06:47 Exim configuration error in line 2:
main option "local_scan_path" unknown

Any idee are welcome,
Guy
