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 [email protected] 而不是 Bcc: 并完全停止发送到 [email protected] 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

默认情况下不会重写地址；为此，Sendmail 功能是
genericstablePostfix 调用的generic(5)，因此理论上添加到您的
main.cf然后添加条目，/etc/postfix/generic例如然后运行
postmap /etc/postfix/generic并重新启动 Postfix 应该会导致地址重写。（这可能会因邮件传输代理（如 Postfix）使用的信封地址与邮件本身中存在的正文地址之间的区别而变得复杂......）在这种
| sendmail情况下，您应该提供适当的To地址标头以及Subject，或者使用邮件用户代理（例如mail）为您处理这些详细信息。
