没有可用的 sasl 身份验证机制

我正在尝试使用 Dovecot+Postfix+Mysql，到目前为止一切正常。自从从 Debian 6 升级到 7 后，我无法发送邮件。仍然可以接收。

/var/log/mail.log

Oct 22 15:21:24 XXXXXXXX postfix/smtpd[17765]: warning: XXXXX: SASL PLAIN authentication failed: no mechanism available

我尝试研究错误并发现了一些问题，但到目前为止并没有真正的帮助。

这是我的 postconf -n 的输出

和我的 dovecot.conf

protocols = imap pop3
listen = *
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/home/vmail/%d/%n/Maildir

ssl_cert =</etc/ssl/certs/dovecot.pem
ssl_key =</etc/ssl/private/dovecot.pem

namespace {
    type=private
    separator = .
    prefix = INBOX.
    inbox = yes
}

protocol lda {
    log_path = /home/vmail/dovecot-deliver.log
    auth_socket_path = /var/run/dovecot/auth-master
    postmaster_address = [email protected]
    mail_plugins = sieve
}

plugin {
    sieve_global_path = /home/vmail/globalsieverc
}

protocol pop3 {
    pop3_uidl_format = %08Xu%08Xv
}

service auth {
    user = root
}

passdb {
        driver = sql
        args = /etc/dovecot/dovecot-sql.conf
}

userdb {
        driver = static
        args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
}

service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = vmail
    mode = 0666
    user = vmail
  }
  unix_listener auth-master {
    mode = 0666
  }
}

升级后我所做的唯一更改是调整 dovecot.conf 以与已安装的新版 dovecot 配合使用。我猜想服务身份验证部分中存在错误，但经过大量谷歌搜索后仍未找到原因。

您能提供进一步的帮助吗？

答案1

因此，您已经告诉 dovecot 设置此服务以进行身份​​验证：

‘unix_listener /var/spool/postfix/private/auth’

您在哪里告诉 Postfix 与该套接字通信？
