Getting SMTPServerDisconnected error sending email through python

When trying to send the email with the host:cpanel.freehosting.com
P it is raising an error like
This is my code:
import smtplib
s = smtplib.SMTP('cpanel.freehosting.com', 465)
s.starttls()
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
This is the error i got:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/smtplib.py", line 251, in __init__
(code, msg) = self.connect(host, port)
File "/usr/lib/python3.5/smtplib.py", line 337, in connect
(code, msg) = self.getreply()
File "/usr/lib/python3.5/smtplib.py", line 393, in getreply
raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed

Considering the port number you are using I'd try with SMTP_SSL instead of SMTP and starttls().
https://docs.python.org/3/library/smtplib.html:
An SMTP_SSL instance behaves exactly the same as instances of SMTP.
SMTP_SSL should be used for situations where SSL is required from the
beginning of the connection and using starttls() is not appropriate.
If host is not specified, the local host is used. If port is zero, the
standard SMTP-over-SSL port (465) is used.
STARTTLS is a form of opportunistic TLS, it is supposed to be used with old protocols, that originally did't support TLS, to upgrade the connection.
The port 465 was used before the introduction of STARTTLS for SMTPS, which is now deprecated.
import smtplib
s = smtplib.SMTP_SSL('cpanel.freehosting.com', 465)
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
Alternatively you should be able to use port 25 with your original code.
import smtplib
s = smtplib.SMTP('cpanel.freehosting.com', 25)
s.starttls()
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
In both examples you can completely omit the port number as you are using the default ports.

I have tried sending a mail through python...

I set the proxy through cmd in windows.
Please help me with this.
Update :
I am sure with the internet connection :
import urllib2
def internet_on():
try:
response=urllib2.urlopen('https://www.google.co.in',timeout=1)
return True
except urllib2.URLError as err: pass
return False
print internet_on()
Output is True

Your code works fine for me, so it's probably the connection settings.
Try changing server to:
server = smtplib.SMTP('64.233.184.108')
(that's the IP address of smtp.gmail.com, to bypass DNS resolution)

Try updating the server = smtplib.SMTP('smtp.gmail.com') to include a port. The port for gmail is 587, so add that as a second parameter: server = smtplib.SMTP('smtp.gmail.com', 587)
If this does not work, make sure that you have used this site to make sure that the account will let you in:

Send email from server python

I am trying to send an email form my server with python, I asked my server provider what port to use for this and they said "choose SMTP Ports 465 (Secure SSL/TLS outgoing server) , 25 ( Non-SSL outgoing server)." Not sure what this exactly means but currently I am using 25, here is my code
#! /usr/bin/python
import smtplib
import smtplib
server = smtplib.SMTP('smtp.gmail.com', 25)
#Next, log in to the server
server.login("youremailusername", "password")
#Send the mail
msg = "\nHello!" # The /n separates the message from the headers
server.sendmail("you#gmail.com", "target#example.com", msg)
I filled in my username (which is my email address right) and password,a dn the target but it is not working, when I try to navigate to the url where my py script is, it just doesn't load. I have an internet connection cause I am loving other things, and go to other pages on my server. I have also tried running with cron jobs but that also doesn't work.
The permissions on the script are 0755, is there a problem with the script?
When i ran with cron jobs here is the traceback
Traceback (most recent call last):
File "/home/spencerf/public_html/cgi-bin/send_email.py", line 6, in <module>

Thanks for the help in advance.
EDIT
here is updated error log with the port at 587

When I had server = smtplib.SMTP('telnet smtp.gmail.com', 587)
I got this error

BUG:
First of all you are using gmail server not your company server to send mail .For gmail server the output port is 587
The code:
Due to security issues gmail blocks accessing mail via code or program
But still you can use gmail to send mail via code if you do the following things
What i have done in code :
1.Added a error object to get the error message
import smtplib
try:
server = smtplib.SMTP('smtp.gmail.com', 587)
#Next, log in to the server
server.login("youremailusername", "password")
#Send the mail
msg = "\nHello!" # The /n separates the message from the headers
server.sendmail("you#gmail.com", "target#example.com", msg)
print "Successfully sent email"
except smtplib.SMTPException,error:
print str(error)
print "Error: unable to send email"
If u ran this code u would see a error message like this stating that google is not allowing u to login via code
Things to change in gmail:
1.Login to gmail
2.Go to this link https://www.google.com/settings/security/lesssecureapps
3.Click enable then retry the code
Hopes it help :)
But there are security threats if u enable it
Updated
import smtplib
try:
content = 'test'
mail = smtplib.SMTP('smtp.gmail.com',587)
mail.ehlo()
mail.starttls()
mail.login("ABC#gmail.com", "password")
mail.sendmail("ABC#gmail.com", "recivermailaddress", content)
mail.quit
print "Successfully sent email"
except smtplib.SMTPException,error:
print str(error)

In python, please download yagmail (disclaimer: I'm the developer):
pip install yagmail
It is then simply a matter of:
import yagmail
yag = yagmail.SMTP("you#gmail.com", "password")
yag.send("target#example.com", 'This is the subject', 'Hello!')
I guess it mostly just has to do with the fact that you gave a wrong port (smtp.gmail.com is not at 25).
On the github you can also see a common list of errors.

Error during sending mail

I try to send mail via python. I got a function:
def mail():
fromaddr = 'mymail#gmail.com'
toaddrs = 'targetmail#o2.pl'
msg = 'There was a terrible error that occured and I wanted you to know!'
# Credentials (if needed)
username = 'mymail#gmail.com'
password = 'password'
# The actual mail send
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.ehlo()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
When I try to execute this function it whows me WinError 10060. Error text below:
Traceback (most recent call last):

I don't know where is problem... i tried many mail servers (gmail,o2,wp,) all of them returned the same error. I tried also other available solutions in the internet to send mail via pyython.... the same problem...
Please help

According to your posted backtrace, you are failing at the line
server = smtplib.SMTP('smtp.gmail.com:587')
I've run that line and it works for me. The clue is in the TimeoutError. I believe you are having networking problems and the code itself is fine.
You do have an extra call to ehlo but as it stands you are not getting that far.
Additionally, it would probably be better to pass the port number as a separate argument, rather than using a colon to split it. E.g.
server = smtplib.SMTP(host='smtp.gmail.com', port=587)
The documentation for smptlib is here: https://docs.python.org/2/library/smtplib.html

Try removing the second server.ehlo() . The one just before login. That worked for me.

toaddrs should be a list
toaddrs = ['targetmail#o2.pl']

Emailing smtp with Python error

I can't figure out why this isn't working. I'm trying to send an email from my school email address with this code I got online. The same code works for sending from my GMail address. Does anyone know what this error means? The error occurs after waiting for about one and a half minutes.
import smtplib
FROMADDR = "FROM_EMAIL"
LOGIN = "USERNAME"
PASSWORD = "PASSWORD"
TOADDRS = ["TO_EMAIL"]
SUBJECT = "Test"
msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n"
% (FROMADDR, ", ".join(TOADDRS), SUBJECT) )
msg += "some text\r\n"
server = smtplib.SMTP('OUTGOING_SMTP', 465)
server.set_debuglevel(1)
server.ehlo()
server.starttls()
server.login(LOGIN, PASSWORD)
server.sendmail(FROMADDR, TOADDRS, msg)
server.quit()
And here's the error I get:
Traceback (most recent call last):
File "emailer.py", line 13, in
server = smtplib.SMTP('OUTGOING_SMTP', 465)
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 239, in init

It's likely that your school's SMTP server does not permit outside access to port 587. Gmail does, and requires authentication to ensure that you are who you say you are (and so that spammers can't send email appearing to be from you unless they know your password). Your school may have chosen to set up their mail server so that only connections from within the school can send mail in this way.
