Description

Commerce does not seem to be honouring the .env variable for SYSTEM_EMAIL_ADDRESS on notifications. This appears to be a new error in Commerce as it was working previously.

Failed email job:

My Commerce General Settings panel:

Craft Email Settings panel:

Steps to reproduce

1. Set an email address in your .env file.
2. Add that variable to your Craft Email settings panel
3. Trigger a Commerce notification email

Expected behavior

The email is sent

Actual behavior

The email is not sent and the job fails with the error "Email "$SYSTEM_EMAIL_ADDRESS" does not comply with addr-spec of RFC 2822."

Can you confirm that $SYSTEM_EMAIL_ADDRESS exists in the environment the email is being sent in?
