Django电子邮件：客户端无权作为此发件人发送

我可以使用此SO答案中提供的功能通过smtplib发送电子邮件：https://stackoverflow.com/a/12424439/614770

from __future__ import print_function

def send_email(user, pwd, recipient, subject, body):
    import smtplib

    FROM = user
    TO = recipient if type(recipient) is list else [recipient]
    SUBJECT = subject
    TEXT = body

    # Prepare actual message
    message = """From: %s\nTo: %s\nSubject: %s\n\n%s
    """ % (FROM, ', '.join(TO), SUBJECT, TEXT)
    try:
        server = smtplib.SMTP('smtp.office365.com', 587)
        server.ehlo()
        server.starttls()
        server.login(user, pwd)
        server.sendmail(FROM, TO, message)
        server.close()
        print('Successfully sent the mail')
    except:
        print('Failed to send mail')


if __name__ == '__main__':
    send_email(
        'my@email.com', 'password', 'my@email.com', 
        'Test Email', 'Can you see this?')

但是，当我尝试通过django发送电子邮件时收到以下错误：

settings.py

# Email
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.office365.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'my@email.com'
EMAIL_HOST_PASSWORD = 'password'

Command line

我在django中错误配置了什么吗？
