postfix does not work with amavis

[digitalphoto]

Hallo,

As reported before, I can't make amavis work with postfix.
Postfix only works when I comment the last statement on main.cf
Otherwise the messages are:

Feb 09 15:15:07 kolab.usina-de-imagens.com.br <warning> postfix/qmgr[23452]: 
warning: premature end-of-input on private/smtp-amavis socket while reading 
input attribute name
Feb 09 15:15:07 kolab.usina-de-imagens.com.br <warning> postfix/qmgr[23452]: 
warning: private/smtp-amavis socket: malformed response

The system is running on a jail on FreeBSD release 5.3

TIA,

Joe Karma
