Email has a `reply-to` header specifically for this purpose. The from field, I believe, was meant to be the actual from, which can now be verified via DKIM keys. A common case might be: `from: tom@co, reply-to: support@co` so that the response goes to the full support team but it is still clear who the sender is.
- howard941 8y agoRe From, there's From: and there's also From_ (From space) that's created by the terminal mail server from the (E)SMTP handshake. All but the most recent (topmost) Received: header(s), supplied by the terminal mail server, are easily spoofed...
- mehrdadn 8y agoYou probably already know this but for anyone else reading: "from" isn't quite the same as "sender" (there's also a Sender field and it's optional). I think Sender is supposed to represent something like your secretary sending an email on your behalf? Or another situation where the entity sending is not the same one nominally writing the message.
