bad transport type error when integerate Postfix, amavis, and clamav

[needee]

OS: SUSE Enterprise 10
# rpm -q postfix
postfix-2.2.9-10.2
# rpm -q clamav
clamav-0.88.2-3.2
# rpm -q amavisd-new
amavisd-new-2.3.3-17.2

I have to config the Postfix + Clamav + Amavisd-new
I followed the http://www.khoosys.net/single.htm?ipg=1565
Prblm:
-----
postfix doesnt starts when configuring postfix to use content_filter program
# rcpostfix start
Starting mail service (Postfix) done
# rcpostfix status
Checking for service Postfix: dead


#tail -f /var/log/mail
Mar 21 10:42:07 www1 postfix/master[5091]: fatal: /etc/postfix/master.cf: line 74: bad transport type: smtp_data_done_timeout=1200
in master.cf, I comment the line
#-o smtp_data_done_timeout=1200
then # rcpostfix start
#tail -f /var/log/mail
Mar 21 11:15:06 www1 postfix/master[6460]: fatal: /etc/postfix/master.cf: line 77: bad transport type: smtp_send_xforward_command=yes

My Configurations:
