私は（require_filesを介して）許可しないように言ったが、exim4が私のメッセージを受け入れるのはなぜですか？

仮想ドメインには exim を使用します。次のルータを作成しました。

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]受け入れてはならないテストメールを送信しました。

# 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
#

しかし、メッセージは承認され、eximはmaildirを生成しますoehtgczb！

なぜ？私はまたどう言うことができますか？

編集：はい、ルーターに電話をかけます。

# 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
