I was using Gmail to send some emails through a program I have hosted on PythonAnywhere with SMTPlib.. It is a single user program so I thought this would work fine. However I am running into security issues with Gmail where it will sometimes block the login and not send the mail. So I decided to switch, because I have a website on Hostgator and figured I could just send it through there.. However I am now getting an Error 111 Connection Refused response when trying to send mail. I know for a fact the username/password and SMPT setting are exactly what HostGator recommends for a manual setup..

def sendmail(toaddr, msg):
    fromaddr = 'john@usmith.com'
    cc = 'chris@*************.com'
    msg['Cc'] = cc
    server = smtplib.SMTP('gator3119.hostgator.com', 465)
    server.login(fromaddr, "*******")
    text = msg.as_string()
    server.sendmail(fromaddr, [toaddr, cc], text)
    server.quit()

Here is the full trace-back

Any ideas why this would not work as desired? I've also tried using the Non-Secure settings for HostGator and got the same error response.

  • Are you using a free PythonAnywhere account? The only option for free accounts is GMail's SMTP, other servers are blocked as an antispam measure. – Giles Thomas Feb 13 '17 at 17:21
  • Ah, this makes sense. Alright thank you for the heads. I thought maybe HostGator was blocking it on me. Thanks again! – Christopher Nelson Feb 13 '17 at 22:23

You can change you code to:

server = smtplib.SMTP('gator3119.hostgator.com:465')
server.starttls()
server.login(fromaddr, "*******")

Or you can change your SMTP to SMTP_SSL:

server = smtplib.SMTP_SSL('gator3119.hostgator.com:465')
server.login(fromaddr, "*******")
