我在我的 Debian Wheezy 系统上安装了邮件服务器（postfix / dovecot），但无法发送邮件。
由于我只想管理邮件服务器，还没有域名，所以我正在使用服务器的外部 IP 地址。根据文档，这应该可行。
编辑我：该用户存在，我可以验证 IMAP 和 SMTP。
编辑二：MySQL 用户发送方映射（如评论中所述）返回user@ip
日志文件显示错误消息
NOQUEUE: reject: RCPT from [...]: 553 5.7.1 <user@ip>: Sender address rejected: not owned by user user@ip; from=<user@ip> to=<user@ip> proto=ESMTP helo=<[192.168.24.10]>
发件人地址等于（SASL）登录用户名，因此错误消息对我来说似乎没有什么意义。
我可能要在这里提一下，我搜索了整个网络，但没有找到解决方案。我没有对配置进行太多编辑，只master.cf在 中启用了 smtps 和主机、IP 地址和 mysql 映射main.cf。其余部分未受影响。
我这里可能存在什么问题？

答案1
我遇到了这个错误，问题出在我的
smtpd_sender_login_maps =ldap:/etc/postfix/ldap-query-file.cf
由于我的调整，它传递了虚假的价值。
希望这会有所帮助
