Dovecot SMTPD Sasl 身份验证错误：致命：没有 SASL 身份验证机制

  • 772

我用谷歌搜索了这个错误，但我读过/尝试过的任何东西都没有——任何人都知道它是什么

错误日志：

Feb 23 22:35:36 localhost postfix/smtpd[5278]: connect from localhost.localdomain[127.0.0.1]
Feb 23 22:35:36 localhost postfix/smtpd[5278]: warning: SASL: Connect to smtpd failed: No such file or directory
Feb 23 22:35:36 localhost postfix/smtpd[5278]: fatal: no SASL authentication mechanisms
Feb 23 22:35:37 localhost postfix/master[5214]: warning: process /usr/libexec/postfix/smtpd pid 5278 exit status 1
Feb 23 22:35:37 localhost postfix/master[5214]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

后缀/main.cf：

queue_directory = /var/spool/postfix
smtpd_sasl_type = dovecot
smptd_sasl_path = private/auth
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = yes

dovecot/conf.d/10-master.conf：

  # Postfix smtp-auth
  unix_listener /var/spool/postfix/private/auth {
    mode = 0666
    user = postfix
    group = postfix
  }

Dovecot 在后缀中可用：

[root@localhost ~]# postconf -a
cyrus
dovecot

插座：

[root@localhost conf.d]# ls -l /var/spool/postfix/private/auth
srw-rw-rw-. 1 postfix postfix 0 Feb 23 22:46 /var/spool/postfix/private/auth

Telnet 立即超时：

[root@localhost ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

授权工作：

[root@localhost ~]# doveadm auth adrian
Password:
passdb: adrian auth succeeded
extra fields:
  user=adrian

操作系统：Centos 6.4 Dovecot：2.1.17 后缀：2.6.6

postconf -n 的编辑结果：

[root@localhost ~]# postconf -n

  1. Best Answer

    如您所见，smtpd_sasl_path我们的输出中没有postconf -n

    为什么？答案很简单。因为没有smtpd_sasl_path套路。看看你的第一个片段：里面有一个错字。您写了smptd_sasl_path = private/auth - 但 sm tp d 和 sm pt d之间存在差异。

    因为 Postfix 没有在哪里找到套接字的信息，所以 Postfix 声称“连接失败”。

    修复它，它会工作。:-)

    最后：下次记住：postconf -n仔细阅读并确保 Postfix 具有您认为 Postfix 应该具有的相同信息，这始终是找出故障的重要步骤。

  2. 有同样的错误，不同的问题。

    必须编辑/etc/dovecot/conf.d/10-master.conf和取消注释unix_listener并添加user和group行。

    service auth {
   unix_listener /var/spool/postfix/private/auth {
      mode = 0660
      user = postfix
      group = postfix
   }
