Exim：接受后缀别名作为 ACL 中的 FROM 地址

Exim：接受后缀别名作为 ACL 中的 FROM 地址

我使用 exim 发送邮件。对于 SMTP 认证用户，我已经添加了几个 ACL，并想添加另一个允许后缀别名的 ACL。后缀别名是电子邮件地址，例如“[电子邮件保护]“。

环境如下：

  • 用户名（完整电子邮件地址）存储在$authenticated_id
  • 设置的 FROM 地址存储在$sender_address
  • “用户”在“[电子邮件保护]“可以在${local_part:$authenticated_id}
  • 经过身份验证的用户的域名位于${domain:$authenticated_id}

现在我想要实现如下的 ACL 规则：

# accept if FROM address is a suffix alias of authenticated address
accept
  condition = ${if match {$sender_address} {${local_part:$authenticated_id}+{*}@${domain:$authenticated_id}} }
  logwrite = AUTH OK - FROM address $sender_address is a suffix alias of authenticated user

不幸的是，ACL 规则似乎不正确。我收到以下错误消息：

failed to expand ACL string "${if match {$sender_address} {${local_part:$authenticated_id}+{*}@${domain:$authenticated_id}} }": curly-bracket problem in conditional yes/no parsing: 'yes' part did not start with '{'

问：上述条件有什么问题？实现这一目标的正确条件是什么样的？

答案1

尝试了几次后，我终于成功了。规则应该是这样的：

# accept if FROM address is a suffix alias of authenticated address
accept
  condition = ${if match {$sender_address} {(${local_part:$authenticated_id}\+.*@${domain:$authenticated_id})}}
  logwrite = AUTH OK - FROM address $sender_address is a suffix alias of authenticated user
