when I try to send mail using outlook and python error occurred this type of question is already on this site but doesn't help to me.
from redmail import outlook
outlook.user_name = "example#hotmail.com"
outlook.password = "<MY PASSWORD>"
outlook.send(
receivers=["you#example.com"],
subject="An example",
text="Hi, this is an example."
)
Error logs:
SMTPAuthenticationError: (535, b'5.7.139 Authentication unsuccessful, basic authentication is disabled. [MA0PR01CA0094.INDPRD01.PROD.OUTLOOK.COM]')
This may be related to the security vulnerability of OpenSSL.https://www.openssl.org/source/
It seems that Microsoft has restricted the 25 port of SMTP service.
But this problem was solved last night. Now I can normally access both Python and Java.
I am attempting to run a python script to automate sending emails but I keep running into this error.
Any suggestions on how to fix this?
import smtplib
from email import message
from_addr = 'myemail#gmail.com'
to_addr = 'myemail#gmail.com'
subject = 'Test Email'
body = 'Test'
msg = message.Message()

msg.add_header('to', to_addr)
msg.add_header('subject', subject)
msg.set_payload(body)
server = smtplib.SMTP('smtp.gmail.com', 587)
server.login(from_addr, 'password')
The error:

smtplib.SMTPNotSupportedError: SMTP AUTH extension not supported by server.
I'm not shure, but for gmail you need https://myaccount.google.com/lesssecureapps Allow less secure apps: ON setting.
Or you need Google APIs for authentication: https://developers.google.com/gmail/api/quickstart/python
I was having the same issue. Google recent ended support for "allow less secure apps" and the commonly recommended answer of using an app password also does not appear to work reliably either (it will work sometimes, but then gmail will start rejecting the authentication a day or two later).
Google's suggested quickstart guide (https://developers.google.com/gmail/api/guides/sending) is incomplete but does eventually work. In that process, you will get an error because you did not redirect the URI. You'll need to add this to the approved URIs within your google API console and then follow the link again.
You will hit a 2nd issue because your user will not be approved to use your own project. You will need to add your gmail account as a test user.
Once you have the URI forwarding correctly and you are approved to use your own app, you will then get an error (HTTP Error 403) because the Gmail API will not be activated. Go back to the google API console and enable the Gmail API. Finally, you can run the quickstart.py file again and it will complete without errors.
I have not yet tested this solution for actually sending email, but it does appear to grant your app full access to the email account that you set up. I also do not know if this is a long term solution or if there are tokens which will time out.
Based on the difficulty of this, it seems that finding another email SMTP service may be a better solution if that's possible for your situation.
You can get your app password to login your account via smtp. This solves the issue for less secure app feature.
Coming towards your error it might be due to something is not supported but here I see you have not started TLS connection. Starting TLS connection can solve this error if there's no other issue.
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(from_addr, 'password') # here you can need to use app password
This should solve the error most of the time if other things are correct.
EDIT: The main error is when this script runs from different IP / Wifi or whatever. It will just cancel it like skip over it or whatever.
I'm trying to send an email with text that says something. (or I can insert a variable for example: score = 32 and I would put 'score' in body without the ' '.)
The following code is what I'm using:
import smtplib
gmail_user = 'name#gmail.com'
gmail_password = 'password'
sent_from = gmail_user
to = 'me#gmail.com'
subject = 'OMG Super Important Message'
body = 'blah blah blah this is a message'
email_text = """\
From: %s
To: %s
Subject: %s
%s
""" % (sent_from, ", ".join(to), subject, body)
try:
server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.ehlo()
server.login(gmail_user, gmail_password)
server.sendmail(sent_from, to, email_text)
server.close()
print 'Email sent!'
except:
print 'Something went wrong...'
So where it says 'body' I can put like a variable not just a text and it would send. But now,
when I send a program to someone and they go through the steps until this and the script will just skip it because the print 'loaded successful' one won't print meaning it didn't work. Any help on how to fix?
You'll have to enable less secure apps in order to access your gmail account via smtplib.
Let less secure apps access your account
If an app or device doesn’t meet our security standards, Google will block anyone who tries to sign in from that app or device. Because these apps and devices are easier to break into, blocking them helps keep your account safe.
Some examples of apps that do not support the latest security standards include:
The Mail app on your iPhone or iPad with version 6 or below
The Mail app on your Windows phone preceding the 8.1 release
Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird
Change account access for less secure apps
To help keep Google Accounts through work, school, or other groups more secure, we block some less secure apps from using them. If you have this kind of account, you’ll see a "Password incorrect" error when trying to sign in. If so, you have two options:
Option 1: Install a more secure app that uses stronger security measures. All Google products, like Gmail, use the latest security measures.
Option 2: Change your settings to allow less secure apps into your account. We don't recommend this option because it can make it easier for someone to break into your account. If you want to allow access anyway, follow these steps:
Go to the "Less secure apps" section of my Account.
Turn on Allow less secure apps. (Note: If your administrator has locked less secure app account access, this setting is hidden.)
If you still can't sign in to your account, learn more about the "password incorrect" error.
I am attempting to send an email in Python, through Gmail. Here is my code:
import smtplib
fromaddr = '......................'
toaddrs = '......................'
msg = 'Spam email Test'
username = '.......'
password = '.......'
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login(username, password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
I get the error:
Traceback (most recent call last):
File "email_send.py", line 18, in <module>
server.login(username, password)
File "C:\.....\Python\lib\smtplib.py", line 633
, in login
raise SMTPAuthenticationError(code, resp)

7\n5.7.8 {BADCREDENTIALS} s10sm9426107qam.7 - gsmtp')
This seems to be a problem with the login. I am certain that my login details are correct, except for one thing. Should username be "blah#gmail.com", or simply "blah"? I tried both, same error.
Any idea whats wrong?
NOTE: all the periods are instead of password/email/file paths/etc.
UPDATE:
This feature is no longer supported as of May 30th, 2022. See https://support.google.com/accounts/answer/6010255?hl=en&visit_id=637896899107643254-869975220&p=less-secure-apps&rd=1#zippy=%2Cuse-an-app-password
ORIGINAL ANSWER (No longer working):
I ran into a similar problem and stumbled on this question. I got an SMTP Authentication Error but my user name / pass was correct. Here is what fixed it. I read this:
https://support.google.com/accounts/answer/6010255
In a nutshell, google is not allowing you to log in via smtplib because it has flagged this sort of login as "less secure", so what you have to do is go to this link while you're logged in to your google account, and allow the access:
https://www.google.com/settings/security/lesssecureapps
Once that is set (see my screenshot below), it should work.
Login now works:
smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login('me#gmail.com', 'me_pass')
Response after change:
(235, '2.7.0 Accepted')
Response prior:
smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp')
Still not working? If you still get the SMTPAuthenticationError but now the code is 534, its because the location is unknown. Follow this link:
https://accounts.google.com/DisplayUnlockCaptcha
Click continue and this should give you 10 minutes for registering your new app. So proceed to doing another login attempt now and it should work.
This doesn't seem to work right away you may be stuck for a while getting this error in smptlib:
235 == 'Authentication successful'
503 == 'Error: already authenticated'
The message says to use the browser to sign in:
SMTPAuthenticationError: (534, '5.7.9 Please log in with your web browser and then try again. Learn more at\n5.7.9 https://support.google.com/mail/bin/answer.py?answer=78754 qo11sm4014232igb.17 - gsmtp')
After enabling 'lesssecureapps', go for a coffee, come back, and try the 'DisplayUnlockCaptcha' link again. From user experience, it may take up to an hour for the change to kick in. Then try the sign-in process again.
UPDATE:: See my answer here:
How to send an email with Gmail as provider using Python?
I had the same issue. The Authentication Error can be because of your security settings, the 2-step verification for instance. It wont allow third party apps to override the authentication.
Log in to your Google account, and use these links:
Step 1 [Link of Disabling 2-step verification]:
https://myaccount.google.com/security?utm_source=OGB&utm_medium=act#signin
Step 2: [Link for Allowing less secure apps]
https://myaccount.google.com/u/1/lesssecureapps?pli=1&pageId=none
It should be all good now.
I am also faced with the same error message when I try to use smtplib. The error message was like this;
error (535, b'5.7.8 username and password not accepted.
Google has changed access to less secure apps. Before that, there was a field to give access to. Now you can follow these steps;
Go to Google Account Page>Security>Signing in to Google section
turn on 2-Step Verification. You need this feature on.
When 2SV is on, go to App Password and generate new-app-password for mail access. It will generate it for you, then use this password in gmail_password function in Python.
gmail_password='google_generate_it_for_you'
If you're using smtp.gmail.com, then you have to do the following:
Turn on the less secure apps
You'll get the security mail in your gmail inbox, Click 'Yes,it's me' in that.
Now run your code again.
Denied
The solution of using "Access for the less secure app" in Gmail has been denied (find more here).
Update
By the way, you can get access to the gmail account by the solution proposed by Google, called "App password". The solution is simple:
1. Active two-step verification of the corresponding account.
2. Create an app password.
3. Exactly do the same implementation that you have for sending an email (explained in your question).
Except, replace the password with the generated app password (a sixteen digit password).
For more details you can also follow this post (it's working well for me).
I had same issue. And I fix it with creating an app-password for Email application on Mac.
You can find it at my account -> Security -> Signing in to Google -> App passwords.
below is the link for it.
https://myaccount.google.com/apppasswords?utm_source=google-account&utm_medium=web
If you turn-on 2-Step Verification, you need generate a special app password instead of using your common password.
https://myaccount.google.com/security#signin
if you are getting error this(535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8 https://support.google.com/mail/?p=BadCredentials o60sm2132303pje.21 - gsmtp')
then simply go in you google accountsettings of security section and make a less secure account and turn on the less secure button
I had the same issue , i solved this by allowing "less secure app access" . This can be found in Security tab on Google Account:
Dec, 2022 Update:
You need to use an app password to allow your app to access your google account.
So, you need to:
generate an app password following my answer explaining how to generate an app password.
assign the generated app password to password in your code as shown below:
import smtplib
fromaddr = '......................'
toaddrs = '......................'
msg = 'Spam email Test'
username = '.......'
password = 'xylnudjdiwpojwzm' # Here
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login(username, password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
Enable 2FA for your Google account
Then set an app password for your app
Use that new password
For email created by G-Suite or Google Workspace, you have to ask your admin to activate the Gmail app and assigned it to your email account. Without this step, trying either above methods still does not work.

As per all the answers mentioned above.
Enabling 2Factor Authentication and creating an App Pasword does the trick with SMTP.
NOTE: Less secure apps toggle doesn't work anymore tbh?(Others confirm?)
Update after May 30th, 2022 :
To solve this problem it is necessary to activate two-step
verification on your Gmail account :
https://myaccount.google.com/u/1/security
Then you will have access to a new page to create an App Password :
https://myaccount.google.com/u/1/apppasswords
Finally, using this password on your django application should solve the problem.
Tutorial for more information: https://www.youtube.com/watch?v=sCsMfLf1MTg
less secure apps can now only be used in gmail if you turn on 2 factor auth and then generate an app password for a custom app
these steps worked for me :)
follow these steps https://myaccount.google.com/security
It is no longer possible as google has removed support for Less secure apps.
However you can still use App Passwords
Documentation from google -https://support.google.com/accounts/answer/185833?hl=en
Create & use App Passwords
If you use 2-Step-Verification and get a "password incorrect" error when you sign in, you can try to use an App Password.
Go to your Google Account.
Select Security.
Under "Signing in to Google," select App Passwords. You may need to sign in. If you don’t have this option, it might be because:
2-Step Verification is not set up for your account.
2-Step Verification is only set up for security keys.
Your account is through work, school, or other organization.
You turned on Advanced Protection.
At the bottom, choose Select app and choose the app you using and then Select device and choose the device you’re using and then Generate.
Follow the instructions to enter the App Password. The App Password is the 16-character code in the yellow bar on your device.
Tap Done.
Tip: Most of the time, you’ll only have to enter an App Password once per app or device, so don’t worry about memorizing it.
In my case, I allowed the access, but the problem was that I was using server.login('Name <email>', password). Please, make sure to use only your email here: server.login('youremail#gmail.com', password).

Try turning on less secure apps and make sure that you have smtp.gmail.com or for different search up
I am on a Linux machine. My company has an email exchange server which is already configured. I am using a Python script to try to login to the email server so that I can send an email programmatically. Here is what I have so far -
server = smtplib.SMTP('email-0.abc.com', 25)
server.set_debuglevel(1)
server.ehlo_or_helo_if_needed()
server.login('abc/johndoe', 'pwd')
However, at the server.login command, I get an error as
raise SMTPException("No suitable authentication method found.")
SMTPException: No suitable authentication method found.
Anyone know what the problem is please?
Thanks
You might need to switch to STARTTLS authentication. Here's an example that helped me.
How To Send Email In Python Via SMTPLIB
It seems that your Mail Server is rejecting the plain Authentication method.
What server do you use?
If MS Exchange please see this article: http://www.exchangeinbox.com/article.aspx?i=93
I was getting the same error. My case could be the different from yours but error is same as you mentioned.
In my scenario, I don't have to pass the username and password for authentication as server IP was added in white-list of SMTP mail server. And I was passing username and password for authentication which was giving me the error stating "No suitable authentication method found."
This may not be the case with you but I just thought to share the my experience for the same kind of error so that anyone coming to this thread can benefit from it.
Thanks.
The Exchange server I was connecting to, required NTLM authentication, which is not supported by smtplib out of the box.
As of this writing (January 2022) and according to my modest research, the most maintained Python library that solves this problem, is pyspnego. The following snippet was provided by the library author and worked for me without any modifications:
import base64
import spnego
from smtplib import SMTPException, SMTPAuthenticationError
def ntlm_authenticate(smtp, username, password):
auth = spnego.client(username, password, service="SMTP", protocol="ntlm")
ntlm_negotiate = auth.step()
code, response = smtp.docmd("AUTH", "NTLM " + base64.b64encode(ntlm_negotiate).decode())
if code != 334:
raise SMTPException("Server did not respond as expected to NTLM negotiate message")
ntlm_challenge = base64.b64decode(response)
ntlm_auth = auth.step(ntlm_challenge)
code, response = smtp.docmd("", base64.b64encode(ntlm_auth).decode())
if code != 235:
raise SMTPAuthenticationError(code, response)
