我正在使用dovecot和postgresql为虚拟用户配置exim4，我遇到了一个无法解决的问题，情况是这样的：
我需要当'localdomain'用户尝试向另一个'localdomain'用户或外国用户发送电子邮件时，需要进行身份验证，否则拒绝操作。
实际上我正试图避免任何类型的smtp开放中继。
实际上smtp工作正常，只需要设置该要求，我找不到正确的方法来正确配置exim以获得此行为（是一个acl或路由或传输规则？）
我如何定义此配置？
示例：
220 my-server ESMTP Exim 4.84 Thu, 31 Mar 2016 22:26:28 +0000 ehlo localhost 250-my-server Hello localhost [192.168.1.X] 250-SIZE 52428800 250-8BITMIME 250-PIPELINING 250-AUTH PLAIN LOGIN 250 HELP mail from: a@my-server.com 250 OK rcpt to: b@my-server.com 250 Accepted data 354 Enter message, ending with "." on a line by itself this must not happen, the user 'a@my-server.com' is not authenticated, he must not be able to send any message yet until of use of 'auth login' or 'auth plain' because is a user of local domains. . 250 OK id=1all3Q-0004l2-V4

ACL配置文件：
acl_check_rcpt:
