Hi;

I'm trying to send message via smtp with Python

what I'm doing is :

import smtplib

from email.mime.text import MIMEText

msg = MIMEText('Testing some Mailgun awesomness')
msg['Subject'] = "Hello"
msg['From']    = "user@domain.tld"
msg['To']      = "user@gmail.com"

s = smtplib.SMTP('domain.tld', 587)

s.login('user@domain.tld', '123456')
s.sendmail(msg['From'], msg['To'], msg.as_string())
s.quit()

show to me this error :

 smtplib.SMTPException: SMTP AUTH extension not supported by server. 

my question is :

1. how do I know what is smtp information on my server (host, port, username, password)
2. how can I allow tls connection on my server.

thanks.
