'smtplib.SMTPReciepientsRefused'：收件人地址789不是有效的RFC-5321地址

Question

在我的Python代码中，我遇到一个错误，提示“ smtplib.SMTPReciepientsRefused”。我已经检查了两次，但无法找出孔。谁能帮我填补这些空缺？

from email.mime.text import MIMEText
import smtplib
def send_email(email,X,Y,X1,Y1,location,holder_name):
    from_email="abc@gmail.com"
    from_password="abc123"
    to_email=email

    subject="DNA Record"
    message="Your Data Has Been Recorded successfully"

    msg=MIMEText(message,'html')
    msg['Subject']=subject
    msg['To']=to_email
    msg['From']=from_email

    gmail=smtplib.SMTP('smtp.gmail.com',587)
    gmail.ehlo()
    gmail.starttls()
    gmail.login(from_email,from_password)
    gmail.send_message(msg)
