我有一台运行 mailman 2.1.29 的 Google VM,它拒绝接收引用 Google Compute Services 名称 (new-xxxx.c.agile-being-nnnnnn.internal) 和“拒绝中继访问”的入站电子邮件。主机名已设置为活动 DNS 名称,/etc/hosts 文件也反映了这一点。但我不知道它从哪里得到了“agile-being”这个名称。
谢谢您的任何建议!
其他详细信息:操作系统 = Rocky 8.4,SMTP = Postfix 3.5.8

该设置应包含 localhost 的 IP 地址,但有人从列表中mynetworks
删除了 localhost 的主要地址。请恢复此设置。::1
例如:
mynetworks = [::1]/128, 127.0.0.0/8
也可以完全删除该mynetworks
设置。在这种情况下,受信任的网络将是 localhost 以及与主机位于同一 LAN 上的网络(在 GCE 中,是共享 VPC 网络的虚拟机)。
