What to do about this [SSL: WRONG_VERSION_NUMBER] error?

Having trouble sending email using Python from my laptop.

I was getting this error:

Quote:

smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. For more information, go to\n5.7.8 https://support.google.com/mail/?p=BadCredentials 5b1f17b1804b1-424c82463d4sm34188795e9.10 - gsmtp')

I read I need username and password encoded base64, so I did this:

Quote:

echo -ne "me@gmail.com" | base64

and

Quote:

echo -ne "myapppassword" | base64

Good news! I don't get the BadCredentials error, but I get this [SSL: WRONG_VERSION_NUMBER] error:

How can I know what version I need and get and use that version?

Strangely, using the QQ smtp server, username and password do not need to be base64 and my test mails are sent and received, no ssl error!
