我已经设置了 postfix 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，其中“收件人：”字段为空，“密件抄送：”是我的外部地址。使用 mail -s 时，电子邮件会出现在 gmail 发送文件夹中，其中“收件人：”字段是原始根电子邮件，“密件抄送：”是我的外部地址。
我的转发地址不应该更换吗[电子邮件受保护]在“收件人：”字段中而不是“密件抄送：”中，并停止发送至[电子邮件受保护]共？

# echo -e "Subject:Hello World \n\n Testing email\n" | sendmail root
# echo "testing" | mail -s "test message" root

默认情况下不重写地址；genericstablePostfix 调用了Sendmail 功能generic(5)所以理论上添加
smtp_generic_maps = hash:/etc/postfix/generic
到您的main.cf，然后添加条目，/etc/postfix/generic例如
[email protected] [email protected]
然后运行postmap /etc/postfix/generic并重新启动 Postfix 应该会导致地址重写。 （邮件传输代理（例如 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可能会使情况变得复杂......）
在这种| sendmail情况下，您应该To随 一起提供适当的地址标头Subject，或者使用邮件用户代理（例如mail）来为您处理这些详细信息。
