thanks for help guys, i did now patching the source of my exim 4.05 and recompile, i dont get the localscan_dlopen.patch to work, but i simply copy sa-exim2.0.c to local_scan.c and compiling was successfully, now my server scans for spam as needed! thanks for this software , it s great!!!!! SA-(exim) is great, exim is great, and amavis is great too :)) greetings, volker
