我已经设置了 postfix 来通过我的 gmail 帐户中继 proxmox 消息，并使用别名将我所有的根电子邮件转发到外部地址。使用 sendmail 命令时，可以在 gmail 的已发送文件夹中看到电子邮件，收件人：字段为空，密件抄送：是我的外部地址。使用 mail -s 时，可以在 gmail 发送的文件夹中看到电子邮件，其中 To: 字段作为原始根电子邮件，Bcc: 是我的外部地址。
我的转发地址不应该在 To: 字段中替换 root@pve.home.com 而不是 Bcc: 并完全停止发送到 root@pve.home.com 吗？
根电子邮件的测试命令
# echo -e "Subject:Hello World \n\n Testing email\n" | sendmail root
# echo "testing" | mail -s "test message" root
