Can't send email

[iBuitron]

just a simple dash app.

def send_email(to_email):
    
    outlook.username = '[email protected]'
    outlook.password = 'xxxxx'

    # And then you can send emails
    outlook.send(
        subject="Example email",
        receivers=[to_email],
        text="Hi, this is an email."
    )

getting this error:

smtplib.SMTPHeloError: (501, b'5.5.4 Invalid domain name [SCZP152CA0017.LAMP152.PROD.OUTLOOK.COM 2023-05-04T21:24:07.002Z 08DB4C5CCB756BD2]')

I'm receiving the same error.

This is my snippe code for gmail, hope helps you:
(is made for a web, sending mails from my second account to my main account with the data summinted by the costumer)

import smtplib
from email.mime.text import MIMEText

def send_email(full_name, customer_email, mobile, subject, customer_message):
    # Configurar la conexión SMTP
    smtp_server = 'smtp.gmail.com'
    smtp_port = 465
    
    smtp_user = '[email protected]'
    smtp_password = 'xxxxxxxxxxxxxx'  (this is a app password, not a gmail password, you have to request it on gmail)
    
    from_email = '[email protected]'
    to_email = '[email protected]'

    with smtplib.SMTP_SSL(smtp_server, smtp_port) as server:
        server.login(smtp_user, smtp_password)

        # how i see the data on my main email
        message = f'''

        fullname: {full_name}
        email: {customer_email}
        mobile: {mobile}
        subject: {subject}
        
        --
        {customer_message} 
        --
        
        '''

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

        # send email
        server.send_message(msg, from_email, to_email)

At least yesterday my emails went through. I'll try if I can reproduce this.

Are you still facing the same issue? Or does it persist?

I tested Outlook (and also Gmail) and they both work fine. I wonder if this was a temporary issue in Outlook's servers.
