Have you considered adding test cases to verify the new behavior?

You are right. Let me update the test to check whether this field is passed to backend.

[shakeelansari63]

I have updated the test for verifying new from_email parameter.

@potiuk , would you be able to approve the test workflow for latest commit. Need to re-run the tests as I have email test.

I'm setting PR to request changes to avoid merge.
Needs to wait for @hussein-awala review as he is working on refactoring this operator into the smtp provider.

(This is technical step not to worry)
