Hi,

I finally found what's the problem with amavisd. It writes an error like: Table 'mail.policy' not found...

To solve the problem , insert into the new amavisd.conf file the following two lines with correct values:

@lookup_sql_dsn =
   ( ['DBI:mysql:database=mail;host=127.0.0.1;port=3306', 'mail_admin', 'mail_admin_password'] );

$sql_select_policy = 'SELECT "Y" as local FROM domains WHERE CONCAT("@",domain) IN (%k)';

Great howto!!!
