workmail with django rest framework not work

I got this error (501, b'5.1.7 Invalid MAIL FROM address provided', 'smtp.mail.us-east-1.awsapps.com') but I think it error because Django can not connect to the workmail with this credential. But I wonder why I write the code in python it work.

Hi, I don't think the connection is the problem. Looking at this documentation page the problem is with the email address. Robin

Thank you for provide that but as the error 5.1.7 The sender's address was syntactically invalid. but why I write the python code it work with the credential or it may have some bug in django, I'm not sure

here is the code

import smtplib
import ssl
from email.mime.text import MIMEText

to_email = "tomail@gmail.com"
from_email = "email@domain.com"

message = "test"
msg = MIMEText(message, "html")
msg["Subject"] = "subj"
msg["To"] = to_email
msg["From"] = from_email

server = smtplib.SMTP_SSL("smtp.mail.us-east-1.awsapps.com", 465, context=ssl.create_default_context())

server.set_debuglevel(True)
server.login('email@domain.com', 'password)
server.send_message(msg)
server.quit()
