后缀阻止本地用户发送

在Postfix中，如何禁止本地用户发送电子邮件，比如[email protected]到任何地方？

我用下面的几行写了一个sender_access文件

 # cat sender_access joe REJECT [email protected] REJECT 

并加载为哈希postmap hash:sender_access哈希postmap hash:sender_access ，然后我在main.cf添加该行

 smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_access 

最后我重新启动了postfix。 但用户仍然写入活动队列。 也许有一些其他的select干扰conf。

• 后缀发送邮件到未知的地址
• MAIL FROM地址的最大长度
• 邮局屏幕有时会停止邮件，并且4.3.2服务当前不可用
• 550收件人地址被拒绝：用户未知（回复RCPT TO命令） – 用于外部域
• 更改maildir的位置

这是我的postconf -n ：

 alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases allow_percent_hack = no append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix home_mailbox = Maildir/ inet_interfaces = all mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME mailbox_size_limit = 0 mydestination = mail.example.com, localhost.neencloud.it, , localhost, mail.example.com myhostname = mail.example.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = sender_bcc_maps = hash:/etc/postfix/bcc smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_access smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes virtual_alias_maps = hash:/etc/postfix/virtual 

这是mail.log一部分：
