Email headers when sending to firstname.lastname@example.org
I have setup one of my registered email addresses to auto-forward to email@example.com. However, the email is not recognized by Expensify because the email header has the original sender information. The only way around this is to manually forward, which I do not want to spend the time doing.
QUESTION: what headers (other than sender) can Expensify recognize when an email is sent to firstname.lastname@example.org? I cannot change the sender email, but I can add custom headers. Is there another trigger that I can use?
