我们正在从自己的邮件服务器迁移到 Google Apps，我需要以某种方式将所有收到的邮件同时传送到本地邮件服务器和 Google，直到我们让所有人都迁移过来。我正在按照以下网址给出的说明进行操作https://support.google.com/a/answer/9228551 使用“旧服务器作为主服务器>基于服务器的转发”，我可以使用transport_maps将邮件发送到本地或发送到Google，但不能同时发送到两者。有谁知道如何在不对当前 postfix 设置进行重大更改的情况下将邮件传递到本地帐户和 Google？
这是 postconf -n 的输出（减去显然不需要的东西）
content_filter = scan:blocker.example.com:10025
inet_protocols = ipv4
message_size_limit = 15360000

谢谢你！

因此，我最终按照此处给出的步骤进行操作：https://jyotishp.ml/tutorials/postfix/dual-delivery-for-postfix
效果非常好。不幸的是，您确实必须运行两台服务器，但我找不到任何其他方法来做到这一点。
