Im have been trying to send emails with smtp since yesterday and I have been getting this message :

 SMTPRecipientsRefused: {'abusch@debmc.fcen.uba.ar': (450, '4.1.2 <abusch@debmc.fcen.uba.ar>: Recipient address rejected: Domain not found')}

What can I do? Sorry if my english ins't really good.

This is my code, Am I doing something wrong?

    smtp = smtplib.SMTP('smtp.webfaction.com',587)
    # only for debug
    smtp.set_debuglevel(1)
    smtp.ehlo()
    smtp.starttls()
    smtp.ehlo()
    smtp.login('user','password')

Did you create the subdomain "debmc.fcen.uba.ar" at your domain registrar and set up the MX records? I'm not able to retrieve any MX records for the subdomain.

Its not my domain. Its a domain from a university. What can i do if i dont find MX record?

You will need to check with the university that owns the domain. they would need to create the subdomain and set up MX records.

the problem is that this was working since many years and yesterday stopped working. Is that posible? It isn't just that mail. I have 2400 mails with the same problem

The error message suggests that debmc.fcen.uba.ar does not exist. I think you should open a support ticket so we can did deeper into this.
