Dovecot 錯誤 mail_location not set and autodetection failed

bestlong

用重建的方式升級 Linux 系統後，結果 WebMail 的 IMAP 有問題，檢查 /var/log/maillog 內發現下列訊息：

dovecot: IMAP(bestlong): mail_location not set and autodetection failed: Mail storage autodetection failed with home=/home/bestlong
dovecot: IMAP(bestlong): Fatal: Namespace initialization failed

設定方式都是延用舊環境下的參數，結果來到 Fedora 13 就丟出這個新課題。從訊息字面上的意思去找了 /etc/dovecot.conf 內有這麼一大段註解說明：

1. ##
   
2. ## Mailbox locations and namespaces
   
3. ##
   
4. 
   
5. # Location for users' mailboxes. This is the same as the old default_mail_env
   
6. # setting. The default is empty, which means that Dovecot tries to find the
   
7. # mailboxes automatically. This won't work if the user doesn't have any mail
   
8. # yet, so you should explicitly tell Dovecot the full location.
   
9. #
   
10. # If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
    
11. # isn't enough. You'll also need to tell Dovecot where the other mailboxes are
    
12. # kept. This is called the "root mail directory", and it must be the first
    
13. # path given in the mail_location setting.
    
14. #
    
15. # There are a few special variables you can use, eg.:
    
16. #
    
17. #   %u - username
    
18. #   %n - user part in user@domain, same as %u if there's no domain
    
19. #   %d - domain part in user@domain, empty if there's no domain
    
20. #   %h - home directory
    
21. #
    
22. # See <doc/wiki/Variables.txt> for full list. Some examples:
    
23. #
    
24. #   mail_location = maildir:~/Maildir
    
25. #   mail_location = mbox:~/mail:INBOX=/var/mail/%u
    
26. #   mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
    
27. #
    
28. # <doc/wiki/MailLocation.txt>
    
29. #
    
30. #mail_location =

複製代碼

原來 mail_location 真的沒設定, 看了 examples 就將

1. #mail_location =

複製代碼

改成

1. mail_location = mbox:~/mail:INBOX=/var/mail/%u

複製代碼

然後重新啟動 dovecot 服務後問題就解決了。
