exim4.69smtp认证无法使用

littlebandit

有台用exim做的服务器，现在发现不管有没有认证都能通过它进行邮件的发送。实在无法判定是哪造成的问题
认证相关的配置如下：
dovecot_plain:
    driver = dovecot
    public_name = PLAIN
    server_socket = /var/run/dovecot/auth-client
    server_set_id = $auth1
    server_condition = ${if and {{!match {$auth1}{\N[/]\N}}{eq{${if match {$auth1}{\N[+%]\N}{${lookup{${extract{2}{+%:
@}{$auth1}}}lsearch{/etc/demodomains}{yes}}}{${lookup{$auth1}lsearch{/etc/demousers}{yes}}}}}{}}}{true}{false}}
    server_advertise_condition = ${if or {{def:tls_cipher}{eq{$sender_host_address}{127.0.0.1}}}{1}{0}}

dovecot_login:
  driver = dovecot
  public_name = LOGIN
  server_socket = /var/run/dovecot/auth-client
  server_set_id = $auth1
  server_condition = ${if and {{!match {$auth1}{\N[/]\N}}{eq{${if match {$auth1}{\N[+%]\N}{${lookup{${extract{2}{+%}
{$auth1}}}lsearch{/etc/demodomains}{yes}}}{${lookup{$auth1}lsearch{/etc/demousers}{yes}}}}}{}}}{true}{false}}
  server_advertise_condition = ${if or {{def:tls_cipher}{eq{$sender_host_address}{127.0.0.1}}}{1}{0}}

请教下这类问题该如何处理
