In my code I've tried using asyncio create_connection to connect to get clients to connect to a TCP server. For some reason, the connection is successful when I try use an IPv4 address:
event_loop.create_connection(client_factory, host='127.0.0.1', port=8190)
But the connection fails when I use an IPv6 address:
event_loop.create_connection(client_factory, host='::1', port=8190)
When I use the IPv6 loopback address, I get an OSError:
Traceback (most recent call last):
File "C:\Users\<removed>\AppData\Local\Programs\Python\Python36\lib\asyncio\base_events.py", line 778, in create_connection
raise exceptions[0]

ov.ConnectEx(conn.fileno(), address)
OSError: [WinError 10022] An invalid argument was supplied
Looking at the documentation, it looks like the family parameter for create_connection defaults to socket.AF_UNSPEC. I also tried the same call by specifying the family:
event_loop.create_connection(client_factory, host='::1', port=8190, family=socket.AF_INET6)
But I get the same result. I know setting host to 'localhost' will work for this example, but I want to know how to use any IPv6 address for create_connection.

Here is my code:
import smtplib
connection = smtplib.SMTP("smtp.gmail.com")
connection.starttls()
connection.login(user="mymail#gmail.com", password="mypassowrd")
connection.sendmail(from_addr="mymail#gmail.com", to_addrs="recievermail#gmail.com", msg="Hello")
connection.close()
So I am getting this error:

I turned on Less secure app access:
I turned off every security steps too:
And I also turned off the firewall protection as well.
But Nothing worked.
So please someone help me.
You need to specify the port. In this case, it's 587 for TSL.
Somehow it works, but I don't have profound knowledge to explain why.
I had the same problem, so there is a solution:
connection = smtplib.SMTP("smtp.gmail.com", 587)
I'm doing a code to send emails automatically using Python and a local server (where I work). I don't know why this error happens.
I've tried to connect the server using commands from module smtplib -> smtplib.SMTP_SSL(hot, port) and smtplib.SMTP(hot,port) but both doesn't work.
import smtplib
server = smtplib.SMTP('IPfromCompanyServer')

Make sure you're getting to Mail server IP and port number right. And some clients like Gmail don't allow you to send mails automatically without disabling the secure mail transfer feature.
Additionally you could add this piece of code to your program before you log in.
try:
self.smtp.ehlo()
self.smtp.starttls()
self.smtp.ehlo
except:
print "No TLS "
#login here
And maybe this link outta help out a little:

Before you mark this as a duplicate; I've read the other threads as well. I'm trying to send an email as simple as using the mail() function in php. I simply tried the example from the official python docs. But when I try to connect with the localhost on my linux machine I get:
>>> import smtplib
>>> smtplib.SMTP('localhost')
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr/lib/python2.7/smtplib.py", line 251, in __init__

self.sock = self._get_socket(host, port, self.timeout)
File "/usr/lib/python2.7/smtplib.py", line 286, in _get_socket
return socket.create_connection((host, port), timeout)
File "/usr/lib/python2.7/socket.py", line 571, in create_connection
raise err
error: [Errno 111] Connection refused
I thought this example didn't need an email server to run (just like the php mail() function doesn't need an email-server to run).
Any ideas what I might be doing wrong or how I can get this to send an email? All tips are welcome!
The php mail() function does need a relay to send messages. It defaults to sendmail on Linux machines.
On Windows you have to give it the address of a SMTP server.
In order for any program to send email, you need to connect to a SMTP server. There is no running around that.
I'm trying to get a connection established to a FTP server with SSL from within Python (v3.3.0). But I keep getting a timeout. I am NOT using port 990 as the SSL port (paranoid). Would that be the cause of this problem? And if so, how do I specify the port I am using?
Here's my script:
from ftplib import FTP
from ftplib import FTP_TLS
ftps = FTP_TLS('ip address')
ftps.auth()
ftps.sendcmd('USER uname')
ftps.sendcmd('PASS password')
ftps.prot_p()
ftps.retrlines('LIST')
ftps.close()
And here is the result:
Traceback (most recent call last):
File "Scrpit name removed for posting", line 12, in <module>
ftps.retrlines('LIST')
File "C:\Python33\lib\ftplib.py", line 767, in retrlines
conn = self.transfercmd(cmd)
File "C:\Python33\lib\ftplib.py", line 381, in transfercmd
return self.ntransfercmd(cmd, rest)[0]
File "C:\Python33\lib\ftplib.py", line 742, in ntransfercmd
conn, size = FTP.ntransfercmd(self, cmd, rest)
File "C:\Python33\lib\ftplib.py", line 343, in ntransfercmd
source_address=self.source_address)
File "C:\Python33\lib\socket.py", line 424, in create_connection
raise err
File "C:\Python33\lib\socket.py", line 415, in create_connection
sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
any advice would be greatly appreciated,
After looking at the ftplib source, it doesn't seem to want to use any port but 21.
I think you should be able to work around this, something like
import ftplib
ftplib.FTP.port = 995 # or whatever port you are using
ftps = ftplib.FTP_TLS('hostname', 'user', 'pwd')
ftps.retrlines('LIST')
Set the port through the connect
import ftplib
ftps = ftplib.FTP_TLS()
ftps.connect ('hostname', 991)
I am using poplib to get email from the POP3 server.
But this error occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python26\lib\site-packages\myutils.py", line 251, in dxDown

for res in getaddrinfo(host, port, 0, SOCK_STREAM):

My laptop is in an local network and using a server(ip 192.168.0.1:8080) as proxy to access internet. The error seems poplib cannot interpret the domain "pop3.126.com". How to solve this problem?Thanks!
Your proxy is for http, it doesn't effect the pop3 traffic.
A cursory glance suggests that it's probably not able to resolve the hostname to an IP address.
Can you try one of these:
pop3.126.idns.yeah.net
220.181.15.128
Or paste the output of:
nslookup pop3.126.com
