Python Forum

Hello,
I am trying to just learn how to send e-mails with python. I have found some code online and I am trying to use it but an error keeps appearing. This is the code I am trying to use.

import smtplib

server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.login("my_email", "my_password")
server.sendmail(
  "from_email", 
  "to_email", 
  "Test Message")
server.quit()

When I do this, this is what happens:

Output:
Traceback (most recent call last):
  File "C:\Users\keega\OneDrive\Documents\Python\Email Sender.py", line 4, in <module>
    server.login("k*************[email protected]", "K*****123")

    raise last_exception

Does anyone know what is wrong and how to fix it?
Thanks :)

This error is probably caused because Google blocks sign-in attempts from lesser secured apps. If you login to your gmail account you probably received also an email regarding a lesser secured app trying to sign in to your account?

If you want to turn off this safety feature you can do that here: https://www.google.com/settings/security/lesssecureapps

Here's a troubleshooting guide that should work.

Most likely problem is of "Allowing less secure apps" Go to THIS link and allow less secure apps to login into the account.

Hello Again,
Thank you it has worked. I already did this, but for some reason it didn't work but I did it again and now works fine.
Thank You Both
