我的电子邮件服务器运行 Debian，并安装了 postfix、dovecot、amavis、mailman 和 postfixadmin，并设置了虚拟域。除 mailman 无法将电子邮件转发到非本地域（“拒绝中继访问”）外，其他一切正常，而我可以使用 postfix 认证的 smtp 将电子邮件转发给任何收件人。
以下是我的设置。

提前感谢您提供的任何帮助。
答案1
该relay_domains参数决定 Postfix 中继哪些域到——也就是说，您的电子邮件服务器除了其邮件名之外还将接受邮件的域——所以这行在这里对您没有帮助（无论如何，我认为这是您想要通过它实现的目标）。
您将 MAIL FROM 地址限制为列出的地址/etc/postfix/access- 确保其中包括lists.my-domain.it。
你已经reject_unauth_destination在你的线路上走得很早了smtpd_recipient_restrictions，根据postconf(5)，除非
- 已解析的 RCPT TO 域与 $relay_domains 或其子域匹配，或者
- Postfix 是最终目的地：解析的 RCPT TO 域与 $mydestination、$inet_interfaces、$proxy_interfaces、$virtual_alias_domains 或 $virtual_mailbox_domains 匹配
如果您希望此箱能够发送其生成的任何邮件，则需要permit_mynetworks在之前添加reject_unauth_destination，以便来自您网络的邮件无论发往何处都会得到批准。
