That is the difference between the envelope from and the from on the email.

I usually explain it by comparing it to a letter you send in the US Mail.  What is logged in the mail server logs and in a mail filter is the envelope From & To.  This would be comparable to what is printed on the outside of the envelope.

But the letter inside can have an entirely different From & To and that is what the mail server would use to route and deliver the email.
Wrong, sorry. The mail server does not use the From & To written in the message to route and deliver the message, unless you use specific rules to do so. The mail server uses the envelope information (MAIL FROM, RCPT TO).

The US Mail can only go by the envelope From & To.  And what you are doing can only apply to the envelope From & To as the action is triggered before the body of the email with it's From & To are sent to the mail server.
