Dovecot 設定成功

今天忽然想到，Dovecot不應該出問題，（請看遜掉了）於是就檢查設定檔，將log打開。

Error: Logins with UID 100 (user 鳥毅 ) not permitted (see first_valid_uid in config file)

原來Dovecot將為了增加安全性，只允許user從500開始。因為自己手賤，在adduser時將uid設成100，因此在 /usr/local/etc/dovecot.conf 加上 first_valid_uid = 100 就搞定。當然把uid改成預設的1000之後也行，但還要改我自己的檔案權限...還是改first_valid_uid比較快。

仔細看看，Dovecot真是非常注重安全的程式呀！還絕對禁止root登入。

# Valid UID range for users, defaults to 500 and above. This is mostly
# to make sure that users can't log in as daemons or other system users.
# Note that denying root logins is hardcoded to dovecot binary and can't
# be done even if first_valid_uid is set to 0.
