Python smtlib raising error when trying to send e-mail
Question: I copied this code right from the smtplib docs over here

    
    
    import smtplib
    
    def prompt(prompt):
        return input(prompt).strip()
    
    fromaddr = prompt("From: ")
    toaddrs  = prompt("To: ").split()
    print("Enter message, end with ^D (Unix) or ^Z (Windows):")
    
    # Add the From: and To: headers at the start!
    msg = ("From: %s\r\nTo: %s\r\n\r\n"
           % (fromaddr, ", ".join(toaddrs)))
    while True:
        try:
            line = input()
        except EOFError:
            break
        if not line:
            break
        msg = msg + line
    
    print("Message length is", len(msg))
    
    server = smtplib.SMTP('192.168.2.4')
    server.set_debuglevel(1)
    server.sendmail(fromaddr, toaddrs, msg)
    server.quit()
    

However this error is raised:

    
    
    Traceback (most recent call last):
      File "C:\Python34\geenemail.py", line 24, in <module>
        server = smtplib.SMTP('192.168.2.4')
      File "C:\Python34\lib\smtplib.py", line 242, in __init__
        (code, msg) = self.connect(host, port)
      File "C:\Python34\lib\smtplib.py", line 321, in connect
        self.sock = self._get_socket(host, port, self.timeout)
      File "C:\Python34\lib\smtplib.py", line 292, in _get_socket
        self.source_address)
      File "C:\Python34\lib\socket.py", line 509, in create_connection
        raise err
      File "C:\Python34\lib\socket.py", line 500, in create_connection
        sock.connect(sa)
    ConnectionRefusedError: [WinError 10061] Kan geen verbinding maken omdat de doelcomputer de verbinding actief heeft geweigerd
    

I looked for similar problems but couldn't find a lot, only found someone who
said the firewall might be the problem --> I turned Avast/firewall off, got a
bluescreen from some reason, restarted my PC, Avast/firewall was still off but
still it raised the same error.

I have also tried giving a port value but I still get the same error. What
might be the problem?


Answer: The most likely reason for this error is that there is no SMTP server running
on the computer you are trying to connect to.

    
    
    server = smtplib.SMTP('192.168.2.4')
    

`'192.168.2.4'` should be the address of the SMTP server you are trying to use
to send the email.
