postfix와 dovecot은 /var/spool/mail 대신 /root/Maildir을 사용합니다.

비둘기에서는 이 줄만 바꿨어요

mail_home = maildir:/var/spool/mail/%u

나도 시도했다

mail_location = maildir:/var/spool/mail/%u

/var/spool/mail을 사용하는 대신 이메일을 보내려고 하면 /root/Maildir을 사용하려고 시도하지만 실패합니다! 내 conf에 무슨 문제가 있나요? 구성된 /var/spool/mail이 사용되지 않는 이유는 무엇입니까? selinux 없이 시도했지만 마찬가지입니다. 배포판은 최신 centos 7입니다.
