sendmail and amavisd on 9.0

Hello, I installed sendmail, amavisd and AntiVir on my machine with SuSE 9.0 and configured sysconf to use amavisd with milter. But sendmail does not scan the emails; and I can not find any appropiate line in sendmail.cf that it should use amavis. I could not find any hint in the ReadMes. What's going wrong? Dirk
