为什么 exim4 接受我的消息，尽管我告诉它不应该（通过 require_files）？

我将 exim 用于虚拟域。我创建了以下路由器：

domains_virtual:
  debug_print = "R: domains_virtual for $local_part@$domain"
  driver = accept
  domains = /etc/exim4/domains_virtual.txt
  require_files = /var/mail/virtual/$domain_data/$local_part_data
  transport = virtual_mailbox
  cannot_route_message = Unknown virtual user $local_part@$domain

[email protected]我发送了一封不应被接受的测试邮件：

# ls -la /var/mail/virtual/example.local
insgesamt 30
drwxrwsr-x 3 root mailuser  4 10. Sep 07:34 .
drwxrwsr-x 4 root mailuser  4 10. Sep 06:20 ..
-rw-r--r-- 1 root mailuser 92 10. Sep 06:26 .aliases
drwxrws--- 5 root mailuser  5  9. Mär 2011  ouzncwso
#

然而消息被接受并且 exim 创建了 maildir oehtgczb！

为什么？否则我怎么能告诉它呢？

编辑：是的，调用路由器：

# exim4 -bt [email protected]
R: domains_virtual_forward for [email protected]
R: domains_virtual for [email protected]
[email protected]
  router = domains_virtual, transport = virtual_mailbox

这是我与 localhost 进行 SMTP 会话时的日志：

我想我有一个解决方案。使用local_parts而不是require_files：

domains_virtual:
  debug_print = "R: domains_virtual for $local_part@$domain"
  driver = accept
  domains = /etc/exim4/domains_virtual.txt
  local_parts = dsearch;/var/mail/virtual/$domain_data
  transport = virtual_mailbox
  cannot_route_message = Unknown virtual user $local_part@$domain
