为什么exim4接受我的信息，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我向oehtgczb@example.local发送了一封不应该被接受的测试邮件：
# 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
#但是消息被接受了，exim为oehtgczb创建了maildir！
为什么？不然我怎么说呢？
编辑:是的，路由器被调用：
# exim4 -bt oehtgczb@example.local
R: domains_virtual_forward for oehtgczb@example.local
R: domains_virtual for oehtgczb@example.local
oehtgczb@example.local
router = domains_virtual, transport = virtual_mailbox如果我对本地主机执行SMTP会话，则这是日志：

我想我有办法了。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页面原文内容由Unix & Linux提供。腾讯云小微IT领域专用引擎提供翻译支持
