CentOS 6.5 Webmail 伺服器：警告：SASL：連接到私有/身份驗證失敗：沒有這樣的文件或目錄

我正在嘗試使用 Postfix、Docecot 和 Roundcube 在 CentOS 上執行網路郵件伺服器。每當我嘗試向我的伺服器發送郵件或發送測試電子郵件時，它都會失敗。我可以登錄，所以看起來 Dovecot 還可以。

這是我的伺服器日誌：

Jul  2 14:01:42 phantastyc postfix/smtpd[20154]: warning: SASL: Connect to private/auth failed: No such file or directory
Jul  2 14:01:42 phantastyc postfix/smtpd[20154]: fatal: no SASL authentication mechanisms
Jul  2 14:01:43 phantastyc postfix/master[18459]: warning: process /usr/libexec/postfix/smtpd pid 20154 exit status 1
Jul  2 14:01:43 phantastyc postfix/master[18459]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

當我向我的伺服器發送測試電子郵件時：

Jul  2 14:01:42 phantastyc postfix/smtpd[20154]: connect from mail-ve0-f178.google.com[209.85.128.178]

然後它顯示與上面相同的錯誤。

當我用 Roundcube 撰寫郵件時，它只是掛起，Sending message...過了一會兒說SMTP Error (-1): Connection to server failed，日誌說同樣的消息。

這是我的postconf -n輸出：

alias_database = $alias_maps
alias_maps = hash:/etc/postfix/aliases
broken_sasl_auth_clients = yes

virtual_minimum_uid = 2222

virtual_uid_maps = static:2222

這是doveconf -n輸出：

service auth {
 unix_listener auth-client {
   group = vmail
   mode = 0660
   user = vmail
 }
 unix_listener auth-master {
   group = vmail
   mode = 0660
   user = vmail
 }
 user = root
}
service imap-login {

 user = vmail
}
ssl = no
userdb {
 args = uid=2222 gid=2222 home=/var/vmail/%d/%n allow_all_users=yes
 driver = static
}

當我這樣做時：

[root@phantastyc ~]# ls -l /var/spool/postfix/private/auth
ls: cannot access /var/spool/postfix/private/auth: No such file or directory

它有點工作，除了現在有一個新的錯誤消息：

Jul  3 03:03:14 phantastyc postfix/trivial-rewrite[23348]: fatal: open database /etc/postfix/vmail_domains.db: No such file or directory
Jul  3 03:03:15 phantastyc postfix/master[18459]: warning: process /usr/libexec/postfix/trivial-rewrite pid 23348 exit status 1
Jul  3 03:03:15 phantastyc postfix/master[18459]: warning: /usr/libexec/postfix/trivial-rewrite: bad command startup -- throttling

此外，Google（我從中發送測試電子郵件的伺服器）返回延遲錯誤，說明與伺服器的連接已斷開，並且會繼續重試。

使用 解決上述問題後postmap，我遇到了另一個問題。

這是一些日誌記錄：

Jul  4 21:51:20 phantastyc postfix/smtpd[13016]: connect from mail-vc0-f171.google.com[209.85.220.171]

Jul  4 21:51:21 phantastyc postfix/smtpd[13016]: disconnect from mail-vc0-f171.google.com[209.85.220.171]

不在本地表中？

這裡是/etc/postfix/vmail_domains：

admin@phantastyc.tk     phantastyc.tk/admin
bnguyen@phantastyc.tk       phantastyc.tk/bnguyen

admin@oa2019.tk         oa2019.tk/admin
bnguyen@oa2019.tk       oa2019.tk/bnguyen

我還搞砸了什麼？

由於日誌說我不能同時擁有域名，因此mydestination我virtual_mailbox_domains將其從mydestination欄位中刪除，現在外發郵件很好。收到的郵件仍然有點不穩定。

Jul  4 22:10:41 phantastyc postfix/smtpd[13160]: connect from mail-vc0-f173.google.com[209.85.220.173]

這把我嚇壞了：

(delivery failed to mailbox /var/vmail/phantastyc.tk/admin: cannot open file: Is a directory)

那是怎麼回事？

這裡是ls /var/vmail/phantastyc.tk/admin：

cur
dovecot.index.log
dovecot.mailbox.log
dovecot.uidlist
dovecot.uidvalidity
dovecot.uidvalidity.53b3965c

這裡是/etc/postfix/vmail_domains：

admin@phantastyc.tk     phantastyc.tk/admin
bnguyen@phantastyc.tk       phantastyc.tk/bnguyen

admin@oa2019.tk         oa2019.tk/admin
bnguyen@oa2019.tk       oa2019.tk/bnguyen

對不起，我沖在自己前面。我應該先這樣做。一個簡單的搜尋發現郵箱目錄上缺少一個尾部斜杠。我的郵件伺服器現在工作正常。

看起來 dovecot 配置和後綴配置不匹配。

在 dovecot 配置中（尤其是在service auth部分中，您只需定義兩個套接字 auth-client和auth-master。添加一個unix_listener包含內容的部分

unix_listener /var/spool/postfix/private/auth {
 mode = 0660
 # Assuming the default Postfix user and group
 user = postfix
 group = postfix        
}
