ZOHO smtp SMTPAuthenticationError at / (535, 'Authentication Failed') Django app -

i trying establish connection via shell on vps code:

import smtplib email.mime.text import mimetext   sender = 'my zoho email' recipient = 'my gmail account email'   msg = mimetext("message text") msg['subject'] = "sent python" msg['from'] = sender msg['to'] = recipient   server = smtplib.smtp_ssl('smtp.zoho.com', 465)  # perform operations via server server.login('my zoho account email', '*********') 

all credentials correct, since login in account @ https://www.zoho.eu/mail/

when try login with:

server.login('my zoho account email', '*********') 

i smtpauthenticationerror , stack trace shows:

 self.connection.login(force_str(self.username), force_str(self.password))   ...  raise smtpauthenticationerror(code, resp) 

my settings.py is:

email_backend = 'django.core.mail.backends.smtp.emailbackend'      email_use_tsl = true email_port = 465 email_host = 'smtp.zoho.com' email_host_user = '**********' email_host_password = '*********' 

there numerous threads on web but, not 1 has answer it. support doesn't answer third day now...

i using nginx , default configuration not set https:// custom configuration , website running on https://.

edit: if try connect on port 587 with:

server = smtplib.smtp_ssl('smtp.zoho.com', 587) 

i get:

sslerror: [ssl: unknown_protocol] unknown protocol (_ssl.c:590) 

this setting have in settings.py , enough working.

#email settings email_use_ssl = true email_host = 'smtp.zoho.com' email_port = 465 email_host_user = 'someone@example.com' email_host_password = 'yourpassword' default_from_email = 'someone@example.com' server_email = 'someone@example.com' 

you can test using quick example django docs.

from django.core.mail import send_mail  send_mail(     'subject here',     'here message.',     'from@example.com',     ['to@example.com'],     fail_silently=false, )
