Can't send email (gmail) via python

I have a code which was working like a half year ago. It basiclly sends email.
import smtplib
import socket
gmail_user="SENDERMAIL"
gmail_password="SENDERPASS"
to = 'SENDTOTHIS'
email_text = "ADSADSADSA"
try:
server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.ehlo()
server.login(gmail_user, gmail_password)
server.starttls()
server.sendmail(gmail_user, to, email_text)
server.close()
#I was using this code below and it was working. I tried above code but it also did not work.
#server = smtplib.SMTP("smtp.gmail.com:587")
#server.ehlo()
#server.starttls()
#server.ehlo()
#server.login(gmail_user, gmail_password)
#server.sendmail(gmail_user, to, email_text)
#server.close()
print("Done")
except Exception as exception:
print(exception)
Here's exception

There are to many ways to solve this problem. I hope this code helps.
The only thing you need to do is filling the required variables.
import socket
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
#
message = "Your message" # Type your message
msg = MIMEMultipart()
password = "********" # Type your password
msg['From'] = "from#gmail.com" # Type your own gmail address
msg['To'] = "To#gmail.com" # Type your friend's mail address
msg['Subject'] = "title" # Type the subject of your message
msg.attach(MIMEText(message, 'plain'))
server = smtplib.SMTP('smtp.gmail.com: 587')
server.starttls()
server.login(msg['From'], password)
server.sendmail(msg['From'], msg['To'], msg.as_string())
server.quit()

I can also advise to use a simpler library (a wrapper on top of smtplib, to make sure there are no other factors involved).... like yagmail (disclaimer: I'm the developer).
Try to see if this works:
import yagmail
yag = yagmail.SMTP("username", "password")
yag.send(subject="hi")

Crash when sending email in Python 2.7.10

I'm trying to send an email within python, but the program is crashing when I run it either as a function in a larger program or on it's own in the interpreter.
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
fromaddr = "exampleg#gmail.com"
toaddr = "recipient#address.com"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "Hi there"
body = "example"
msg.attach(MIMEText(body, 'plain'))
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, "Password")
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()
In the interpreter, it seems to fail with server = smtplib.SMTP('smtp.gmail.com', 587)
Any ideas?

My standard suggestion (as I'm the developer of it) is yagmail.
Install: pip install yagmail
Then:
import yagmail
yag = yagmail.SMTP(fromaddr, "pasword")
yag.send(toaddr, "Hi there", "example")
A lot of things can be made easier using the package, such as HTML email, adding attachments and avoiding having to write passwords in your script.
For the instructions to all of this (and more, sorry for the cliches), have a look at the readme on github.

That's because you are getting error when trying to connect Google SMTP server.
Note that if you are using Google SMTP you should use:
Username: Your gmail address
Password: Your gmail password
And you should be already logged in. If you still get an error, you should check what is the problem in this list: https://stackoverflow.com/a/25238515/1600523
Note: You can also use your own SMTP server.

Python script smtplib for Windows Update notification

I want to send an email using Python smtplib when Windows Update notification is triggered.
Anyone have an idea how to accomplish this?
I searched on here and Google but didn't find anything.
This is the Python code I have to send the email:
import smtplib, getpass
pswd = getpass.getpass('Password:')
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login('...#gmail.com', pswd)
smtpObj.sendmail('...#gmail.com', '...#gmail.com', 'Subject: Windows Update.\nThere is an update available.')
{}
smtpObj.quit()

Strange error in python using SMTPLIB module

still having issues. I just added some code which uses the smtplib module to send an email to the email address that has been entered by the user, however I got this error
File "C:\Python27\lib\smtplib.py", line 555, in login
raise SMTPException("SMTP AUTH extension not supported by server.")
SMTPException: SMTP AUTH extension not supported by server.
The code I used was from a beginners website
import smtplib
server = smtplib.SMTP('smtp.gmail.com', 587)
server.login("youremailusername", "password")
msg = "\nHello!"
server.sendmail("you#gmail.com", "target#example.com", msg)
However in my case, I used the name of a variable which holds the email or the user where it says "target #example.com" Help someone? ALso I would like to know what are the numbers that come after "smtp.gmail.com"? The 587?

you need to add this server.starttls() before login
import smtplib
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login("youremailusername", "password")
msg = "\nHello!"
server.sendmail("you#gmail.com", "target#example.com", msg)
starttls put the SMTP connection in TLS (Transport Layer security)

Python smtplib security

I was experimenting with an email python script and was wondering if when writing a python-based email script is it is less secure as opposed to when credentials are send over the internet when logging into a web page? In the following script, are the user and pass in the clear?
import smtplib
from email.mime.text import MIMEText
GMAIL_LOGIN = 'xxxxxx#gmail.com'
GMAIL_PASSWORD = 'amiexposed?'
def send_email(subject, message, from_addr=GMAIL_LOGIN, to_addr=GMAIL_LOGIN):
msg = MIMEText(message)
msg['Subject'] = 'Test message'
msg['From'] = from_addr
msg['To'] = to_addr
server = smtplib.SMTP('smtp.gmail.com',587)
server.ehlo()
server.starttls()
server.ehlo()
server.login(GMAIL_LOGIN,GMAIL_PASSWORD)
server.sendmail(from_addr, to_addr, msg.as_string())
server.close()
if __name__ == '__main__':
send_email('testing email script', 'This is a test message')

That would entirely depend how the TLS connection is set up. If you are requiring valid certificates (I believe if a certificate which is not trusted is encountered, your startTLS method will throw an exception (I'm not sure you should verify this)). But considering you are setting up TLS, and sending everything over the TLS connection, everything should be encrypted. This means neither your password, username or even your message and addressees will be sent in plain text.
So no, your username and password are not send clear.
