如何configurationamavisd检查远程服务器中的白/黑名单？

在我的amavisdconfiguration中，我有这样的：

@lookup_sql_dsn = ( ['DBI:mysql:database=mydb;host=127.0.0.1;port=3306', 'myuser', 'mypass'] ); $sql_select_policy = 'SELECT *,spamfilter_users.id'. ' FROM spamfilter_users LEFT JOIN spamfilter_policy ON spamfilter_users.policy_id=spamfilter_policy.id'. ' WHERE spamfilter_users.email IN (%k) ORDER BY spamfilter_users.priority DESC'; $sql_select_white_black_list = 'SELECT wb FROM spamfilter_wblist'. ' WHERE (spamfilter_wblist.rid=?) AND (spamfilter_wblist.email IN (%k)) AND (spamfilter_wblist.active="y")' . ' ORDER BY spamfilter_wblist.priority DESC'; 

基本上，我有一个数据库表，您可以在黑色或白色列表中设置电子邮件地址。 它工作的很好，但它在本地数据库中进行search。 是否有可能通过http协议configurationsearch发生在远程服务器上？
