我已经使用 ubuntu、postfix、dovecot 和 mysql 设置了邮件服务器。
尝试从 Web 界面发送邮件，邮件发送没有任何不便。尝试使用笔记本电脑上的电子邮件客户端（使用互联网）却无法发送。我收到此错误：
2 月 13 日 11:44:48 邮件 postfix/submission/smtpd[13066]: 警告：未知的 smtpd 限制：“permit_sasl_autenticated”
下一行是：
2 月 13 日 11:44:48 邮件 postfix/submission/smtpd[13066]: NOQUEUE: 拒绝：来自未知 [37.176.162.9] 的 RCPT：451 4.3.5 服务器配置错误；来自= 至= 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
正如您所见，任何地方都没有permit_sasl_autenticated（并且整个文件中也没有）。
发生了什么事？你能帮我解决这个问题吗？
编辑-添加了我的日志的更完整的部分：

添加您的验证方法添加到您的/etc/master.cf文件中。查找类似以下内容的条目：
# # Postfix 主进程配置文件。有关格式的详细信息 # 有关该文件的信息，请参阅 master(5) 手册页（命令：“man 5 master”）。 # # 编辑此文件后，请不要忘记执行“postfix reload”。 # # ========================================================================== # 服务类型 private unpriv chroot wakeup maxproc 命令 + 参数 # (是) (是) (是) (从不) (100) # ========================================================================== smtp inet n - - - - smtpd -o content_filter=垃圾邮件过滤器 #smtp inet n - - - 1 postscreen #smtpd 通过 - - - - - smtpd #dnsblog unix - - - - 0 dnsblog #tlsproxy unix - - - - 0 tlsproxy 提交 inet n - - - - smtpd -o syslog_name=postfix/提交 -o smtpd_tls_security_level =加密 -o smtpd_sasl_auth_enable=是 -o smtpd_client_restrictions=permit_sasl_authenticated，拒绝 # -o milter_macro_daemon_name=起始 # -o syslog_name=postfix/smtps # -o smtpd_tls_wrappermode=是 # -o smtpd_sasl_auth_enable=是 # -o smtpd_client_restrictions=permit_sasl_authenticated，拒绝 # -o milter_macro_daemon_name=起始
对 Postfix 配置进行更改后，请务必重新启动服务。
