[issue27820] Possible bug in smtplib when initial_response_ok=False

Hello Pandu,

Thank you for this patch and the explanation. Does client blocking on repeated challenge from the server (using of while loop) look okay here? 
The conversation here indicates to me that it is fine. Is there any recommendation or implementation strategies to break the loop (on a malformed server)?

Thanks,
Senthil
