由于我运行了几个免费网站，这些网站都是基于 CMS 的垃圾邮件发送者，他们正在大规模攻击我。因此，我决定设置我的 exim4 安装以将域列入黑名单。Exim 似乎并不关心我内置的任何限制：
acl_check_host:
accept
hosts = +local_domains
deny
log_message = blacklisted
hosts = blacklisted.com
accept
acl_check_data:
deny senders = [email protected]
accept
acl_check_sender:
deny domains = +rbl_blacklist
deny senders = [email protected]
我一点头绪都没有。
