exim configuration with amavis

I want to install Amavis on Debian Woody with Exim 3 and authentification by LDAP runiing. I have done an apt-get install amavis-new

I have this in my exim.conf

# Transport
XX_appendfile:
driver = appendfile
user = XXmail
group = XXmail
mode = 0660
directory_mode = 0770
file = /var/imap/${local_part}
delivery_date_add
envelope_to_add


# Redirector
XX_account:
driver = smartuser
condition = "${lookup ldap {\
ldap://localhost/ou=EMails,ou=YYYYYY,o=ZZZZZZZZ,c=UK\
?accountParam?sub\
?fullAddress=$local_part@$domain} {yes} {no}}"
new_address = "${lookup ldap {\
ldap://localhost/ou=EMails,ou=YYYYYY,o=ZZZZZZZZ,c=UK\
?accountParam?sub\
?fullAddress=$local_part@$domain}\
{$value}}@XX-internal"
transport = XX_appendfile


Which code I must include for Amavis in my exim.conf ?
