I have recently become unable to send any e-mail from my Django app hosted on a DO droplet through smtp.gmail.com. Any time I try, I get the following error message:
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 sh5sm32272477pbc.21 - gsmtp’)
Which is weird, because the username and password used works perfectly when I try to log in manually, or when sending through the exact same Django app from localhost.
I have also tried going through http://www.google.com/accounts/DisplayUnlockCaptcha , as mentioned in the Google support answer.
I have been sending at maximum a couple of hundred e-mail in total from that account, with maybe ~10 a day - so abuse seems to be out of the question for me. I should mention that the account is a paid Google Apps account.
The fact that I can use the exact same settings while using localhost as a server, plus the fact that this error has only appeared recently, makes me think that the error might have something to do with Digital Ocean.
Do you have any ideas about what might cause this?
Thanks and with the best regards, Martin
Ps. for good measure, here are my smtp settings, minus the password (which I am 100% sure is correct):
EMAIL_USE_TLS = True EMAIL_HOST = ‘smtp.gmail.com’ EMAIL_PORT = 587 EMAIL_HOST_USER = ‘info@CoCreately.com’ EMAIL_HOST_PASSWORD = <redacted>

Hey guys, just found what’s going on with those errors.
The problem is that when you have activated the Google Authenticator Verification you also need to set up the 2-Step-Authentication in your gmail account.
Therefore visit https://www.google.com/settings/security - when you have done so, just go back to this page and click the “App Password” - Settings.
Select “Other (custom name)” and enter any name you like. Go ahead and copy the code and paste it to your projects settings.
Done! - This resolved all issues for me.
Greets P4rks!
I had the same problem. I guess it’s a gmail ban, because the Gmail send a mail with this link: https://support.google.com/mail/answer/14257?p=client_login&rd=1
The point is this: https://www.google.com/settings/security/lesssecureapps
You should change the “Access for less secure apps” to Enabled (it was enabled, I changed to disabled and than back to enabled). After a while I could send email.
