OK, I've completely rewritten your Macro.
It had several issues:
- You never copied the Raw Source data so that the Regex Search could be used.
- Even then, it appears there may be two different formats used in the MS Mail Raw Source Header to ID the Authenticated Sender.
I have added a second Regex as follows:
-
Source :
auth-sender: santaana@fakeemail.com
-
Source :
Authentication-results: spf=none (sender IP is ) smtp.mailfrom=JaneSmith@SomeDummyCo.com;
My Macro checks for #1, and if not found, tries #2.
Below is just an example written in response to your request. You will need to use as an example and/or change to meet your workflow automation needs.
