Python login error for email server authentication

I am on a Linux machine. My company has an email exchange server that is already configured. I am using a Python script to try logging into an email server so that I can send emails programmatically. Here is what I still have -

server = smtplib.SMTP('email-0.abc.com', 25) server.set_debuglevel(1) server.ehlo_or_helo_if_needed() server.login('abc/johndoe', 'pwd')

However, in the server.login command, I get an error like

 raise SMTPException("No suitable authentication method found.") SMTPException: No suitable authentication method found.

Does anyone know what the problem is, please?

thanks

You may need to switch to STARTTLS authentication. Here is an example that helped me.

It seems your mail server is rejecting a simple authentication method.

Which server are you using?

If MS Exchange see this article: http://www.exchangeinbox.com/article.aspx?i=93
