How to send mail with Python

Question

I am trying to send a simple mail with python

import smtplib

server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login("[email protected]", "mypassword")

msg = "Hello world"
server.sendmail("[email protected]", "[email protected]", msg)
server.quit()

But I get this err:

server.login("[email protected]", "psw")

File "C:\Python\lib\smtplib.py", line 652, in login

raise SMTPAuthenticationError(code, resp)

Answer 1

It seems as if you require something that Google calls an app password.

Basically, you generate a 16 digit password, which is unique to your app. You enter this specific password in the python program, instead of the password you regularly use to log into your Google account.

This allows you to still enjoy the benefits of 2-step verification while also being able to use third party applications, such as your own python program.

Here are the instructions from Google on how to generate such an app password: https://support.google.com/accounts/answer/185833?hl=en

you can use this code:

import smtplib

session = smtplib.SMTP('smtp.gmail.com', 587)
session.ehlo()
session.starttls()
session.login('[email protected]',' password')
headers = "\r\n".join(["from: " + '[email protected]',
                       "subject: " + "test",
                       "to: " + '[email protected]',
                       "mime-version: 1.0",
                       "content-type: text/html"])

# body_of_email can be plaintext or html!                    
content = headers + "\r\n\r\n" + "body_of_email"
session.sendmail('[email protected]', '[email protected]', content)

just remember if your email is gmail after first run you get an error. after that you should login to your email account and approve access to your account from another app ( you will receive a messege after login)
