Django Password Recovery via Gmail [Errno 110] Connection timed out

I had a password recovery system via email in my web app, which was working perfectly before deployment. However, now that I have succesfully deployed, password recovery is the only feature that is not working, when solicited it stays loading for some time until the error TimeoutError at /password-reset/ [Errno 110] Connection timed out
Here is my settings.py file email configuration:
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = config.get('EMAIL_USER')
EMAIL_HOST_PASSWORD = config.get('EMAIL_PASS')
The credentials are tucked away into config file.
What could be causing this issue?

Does sending emails other than the password reset work? If yes, what kind of email?
What platform is the app deployed on?
What service are you using to send emails?

I added the port to my UFW firewall with sudo ufw allow 587. Also since I deployed through Linode (they currently have port 587 blocked for all users to prevent spam) I had to contact Linode Support, who then lifted the ban of port 587 on my Linode.

How to send a mail using gmail in Django 1.10 on windows [duplicate]

I registered a domain and a private email using namecheap.com. I am trying to send an email from this private email. However, I get the error in the title.
In my settings.py, I have these settings:
EMAIL_HOST = 'mail.privateemail.com'
EMAIL_HOST_USER = 'contact#mysite.com'
EMAIL_HOST_PASSWORD = 'my password'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER
And I am trying to send the email through a view:
send_mail(
'Subject here',
'Here is the message.',
'contact#mysite.com',
['myname#gmail.com'],
fail_silently=False,
)
However, I get this error:
SMTPException at /
STARTTLS extension not supported by server.
Any idea why? Any help is appreciated.
EDIT
After changing the EMAIL_USE_TLS to False, and also removing it to check both separately, I get this error now:
SMTP AUTH extension not supported by server.
Any idea why? Thanks!

your server mail.privateemail.com does not know what is STARTTLS SMTP Commnad is
this may happen in two cases:
your server (mail.privateemail.com) do not support secure communication at all and you need to use plain, non-encrypted communication.
you are trying to connect to the port that is already using SSL as the communication, then STARTTLS to upgrade connection to secure make no sense whatsoever.
your server is configured improperly and ignores STARTTLS on submission port (587).
Judging, that you are connecting to port 587 which should provide plain communication - it's either 1 or 3.
If you want this just work, remove EMAIL_USE_TLS = True or set it to False, otherwise - SMTP server configuration should be fixed.

You may try SSL instead of TLS by making following changes in settings.py
EMAIL_USE_SSL = True
EMAIL_PORT = 465
hope that helps

Either setup TLS on your mail server or use EMAIL_USE_TLS = False.

I am able to resolve the issue with modifying below line of code, by adding port number with server name:
server = smtplib.SMTP('mail.mycompany.com:587')

Not sure if you have solved the problem yet. I also recently try the 2-month free private email package from NameCheap. Here is my code and it works for me as of Jan 2018:
import smtplib
from email.message import EmailMessage
fromaddr = 'account#yourdomain.com'
toaddrs = "recipient#somedomain.com"
SMTPServer = 'mail.privateemail.com'
port = 465 #587
login = "account#yourdomain.com"
password = "password"
msg = EmailMessage()
msgtxt = "http://www.google.com"+"\n\n"+"This is a test."
msg.set_content(msgtxt)
msg['Subject'] = "Test message"
msg['From'] = fromaddr
msg['To'] = toaddrs
server = smtplib.SMTP_SSL(SMTPServer, port) #use smtplib.SMTP() if port is 587
#server.starttls()
server.login(login, password)
server.send_message(msg)
server.quit()
Hope this help!
PS. You can also use port 587, but you have to use smtplib.SMTP() instead of smtplib.SMTP_SSL(), and also have to un-comment the server.starttls() line.

Django: Outlook email smtp timeout in production server

i'm trying to send a SMTP email from Django, using my credentials of Outlook. My code works in localhost, but when I upload my code to production server, it doesn't.
If I use my Gmail credential, it also works in production, but it doesn't with Outlook. So, I think Outlook is configured in a different way, but I dont know.
This is my view code:
def send_my_custom_email():
connection = mail.get_connection(
host = 'smtp-mail.outlook.com',
port = 25,
username = 'myemail#outlook.com',
password = 'mypassword' ,
)
connection.open()
email2send = mail.EmailMessage('hello', 'hello', 'myemail#outlook.com', to=['receiveremail'], connection=connection)
email2send.send()
connection.close()
I know that my configuration setting are right because it can send emails from localhost. These are my settings.py:
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
I already try to check the Outlook settings, but I couldn't find anything about SMTP use.
My exact questions are:
Outlook need aditional settings in production?
The problem is in my code or in Outlook settings?
Why it works in localhost but it does not in production server?

Outlook.com only allows encrypted SMTP TLS connections on port 587. It does not even listen on port 25, that is why you get a timeout.

Django SMTPServerDisconnected: Connection unexpectedly closed using Postfix on Centos

I have installed Postfix on Centos 7 and have successfully configured it to send mail (tested with command line program MailX).
However, when trying to send mail through Django shell or my Django website I am getting:
File "/usr/lib64/python2.7/smtplib.py", line 367, in getreply
raise SMTPServerDisconnected("Connection unexpectedly closed")
SMTPServerDisconnected: Connection unexpectedly closed
My mail configuration in settings.py:
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = False
DEFAULT_FROM_EMAIL = 'Admin <admin#mywebsite.com>'
Any ideas?

Maillog highlighted:
fatal: no SASL authentication mechanisms
Resolved with:
yum install cyrus-sasl-plain

Send email via Python/django on 1&1

I am developing a website with django framework. And I recently tried to release it on a 1&1 shared hosting.
I managed to make the project run well, except for one last “detail”: I can't send email from django.
I tried almost everything in settings (different emails, ports, etc.), but each time I got a beautiful '500 Internal Server Error' =/ (whereas it went fine on a free alwaysdata server)
In order to find the origin of this issue, I tried different things:
to test send_mail and EmailMessage via the python interpreter:
>>> send_mail('a subject', 'a test message', 'mymail#gmail.com', ['mymail#gmail.com'])
Content-Type: text/plain; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Subject: a subject
From: mymail#gmail.com
To: mymail#gmail.com
Date: Tue, 14 Jan 2014 22:12:48 -0000
Message-ID: <20140114221248.6718.86150#infong-fr25.kundenserver.de>
a test message
-------------------------------------------------------------------------------
1
But... I got nothing in my inbox.
My settings being:
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
DEFAULT_FROM_EMAIL = 'mymail#gmail.com'
EMAIL_HOST_USER = 'mymail#gmail.com'
EMAIL_PORT = 587
to connect to an SMTP server via the python interpreter:
./manage.py shell
>>> from smtplib import SMTP
>>> smtp_conn = SMTP()
>>> smtp_conn.connect('smtp.gmail.com', 25)
And nothing happens (I tried it with auth.smtp.1and1.fr, or port 587...); when I interrupt the process, it tells me:
^CTraceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/lib/python2.6/smtplib.py", line 295, in connect
self.sock = self._get_socket(host, port, self.timeout)
File "/usr/lib/python2.6/smtplib.py", line 273, in _get_socket
return socket.create_connection((port, host), timeout)
File "/usr/lib/python2.6/socket.py", line 554, in create_connection
sock.connect(sa)
File "<string>", line 1, in connect
KeyboardInterrupt
to test with a php file:
With a basic:
<?php
if (mail("mymail#gmail.com", "a subject", "a test")) {
echo("<p>Email successfully sent!</p>");
}
else {
echo("<p>Email delivery failed…</p>");
}
?>
And the mail was sent! So, it seems that without SMTP connection, it is possible (at least, via php).
Conclusion
So, my questions are: do you think I can manage to correct this bug, and otherwise is it possible to send mail without smtp connection ("like php")?

1and1 does not allow SMTP within 1and1. To send an email when running on 1and1...
#!/usr/bin/python
import os
mail_to = "sam#comcast.net"
mail_from = "steve#example.com"
subject = "test message"
header = """From: {0}
To: {1}
Subject: {2}
""".format(mail_from, mail_to, subject)
msg = header + "a test from me"
sendmail = os.popen("/usr/lib/sendmail -t", "w")
sendmail.write(msg)
sendmail.close()
The blog post linked shows an example that sends mail using SMTP through 1and1 via an external machine. Perhaps you can override Django's send_mail (or maybe this gives you [or someone else] a hint as to why it doesn't work.) This should allow you to send email in the Python interpreter, anyway.
