Editing MAIL FROM Header

Hello,

I'm getting the following from my external mail server:

2024:02:22-19:28:14 wahine exim-out[** do-not-reply@fw-notify.net P=<> R=smarthost_route T=smarthost_smtp H=smtp.protonmail.ch SMTP error from remote mail server after end of data: 550 5.7.1 Submission not allowed for messages in which header from does not match MAIL FROM

The manual indicates that the ADD HEADER function under SMTP --> ADVANCED will also edit one; however, it does not indicate the syntax required. From the error message above, it's clearly not changing the MAIL FROM header per my wishes.

Here are the instructions from the manual:

The specific syntax to go in the rule creation dialog is not specified.
See what I have:

I must have the syntax wrong somehow, and I'm tired of guessing.
Could someone help me out?

Thanks,

Douglas Almquist

The "Mail From" you see in the logs is actually the Envelope sender address of the Mail, not a mail header inside.
Editing headers will not work here.
