Gmail Sent email LIMIT

[Johnse]

Fixed your code tag look at BBCode
Add this to see the actual smtp conversation before it raise error.

server = smtplib.SMTP('smtp.gmail.com', 587)
server.set_debuglevel(1)
server.ehlo()

thanks for that line of code.
I have the login in the loop so the message is saying too many login attempt.

I move the login code out of the loop and now I got another error message.

Error:
