"""
test_mail.py — one-off SMTP diagnostic. NOT part of the app.

Run on the server, in the app directory, with the venv active:

    python test_mail.py your-address@example.com

It prints the live mail config and tries TWO sends with different From
addresses so we can see whether the problem is SMTP itself or the sender
address the reset email uses. Delete this file once diagnosed.
