Postfix，Dovecot 问题从客户端发送邮件

  • 772

我已经设置了一个带有 ubuntu、postfix、dovecot 和 mysql 的邮件服务器。

尝试从 Web 界面发送邮件邮件出去没有任何不便。从我的笔记本电脑（使用互联网）尝试使用电子邮件客户端我不能。我收到此错误：

2 月 13 日 11:44:48 邮件后缀/提交/smtpd[13066]：警告：未知 smtpd 限制：“permit_sasl_autenticated”

以下是：

2 月 13 日 11:44:48 邮件 postfix/submission/smtpd[13066]: NOQUEUE: reject: RCPT from unknown[37.176.162.9]: 451 4.3.5 服务器配置错误；from= to= proto=ESMTP helo=<[192.168.0.100]>

第二行是我的消息被服务器拒绝。

我检查了 /etc/postfix/main.cf 并且我的 TLS 配置如下：

# TLS parameters
#smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
#smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
#smtpd_use_tls=yes
#smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
#smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

smtpd_tls_cert_file=/etc/dovecot/cert.pem smtpd_tls_key_file=/etc/dovecot/private/cert.pem smtpd_use_tls=yes smtpd_tls_auth_only = yes

#Enabling SMTP for authenticated users, adn handing off autentication to Dovecot smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes

smtpd_recipient_restrictions =
        permit_sasl_authenticated,
        permit_mynetworks,
        reject_unauth_destination

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination

如您所见，没有permit_sasl_autenticated任何地方（整个文件中也没有）。

到底是怎么回事？你能帮我解决这个问题吗？

    将您的身份验证方法添加到您的/etc/master.cf文件中。查找与此类似的条目：

# Postfix 主进程配置文件。有关格式的详细信息
# 文件，参见 master(5) 手册页（命令：“man 5 master”）。
#
# 编辑此文件后不要忘记执行“postfix reload”。

    更改 Postfix 配置后，请务必重新启动服务。
