Research direction

Start with the migrated BPO issue 46011 and its three historical messages, then locate the email component handling Date headers in Python 3.10. The payload names no source file or test, so identify the relevant entry point and expected handling of an invalid Date header before adding regression coverage. Done means the reported invalid header behavior is corrected and tested.
