This is cause the problem.

You are setting msg['To'] to a list. It needs to be a string, e.g.

        if isinstance(mail_to, list):
            msg['To'] = ', '.join(mail_to)
        else:
            msg['To'] = mail_to


Also, when you set headers, they will be capitalized or not as you set
them so set msg['From'], msg['To'], msg['Date'] and msg['Subject'].
