logging.handlers.SMTPHandler raises smtplib.SMTPAuthenticationError - python

I tried this with Verizon and Gmail. Both servers denied authentication. Gmail emailed me that it denied a login attempt because the connection was not using "modern security".
I would like to know how I can use modern security with this logging handler.
logging.handlers.SMTPHandler(mailhost=('', 25),
fromaddr='',
toaddrs='',
subject='',
credentials=('username','password'),
secure=())

For anyone coming back to this, here is how I got the SMTPHandler working with Gmail:
eh = SMTPHandler(mailhost=('smtp.gmail.com', 587),
fromaddr=from_addr,
toaddrs=to_addrs,
subject=subject,
credentials=(username, password),
secure=())
The to_addrs variable is a string in my example. I am not sure if it can be an array or is supposed to be a space or comma-delimited string. The username variable includes the domain, like this: foo#gmail.com.
Most guides said to use port 465, here is the difference if you are curious. However, when I tried to use port 465, I got a SMTP timeout error:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/smtplib.py", line 386, in getreply
line = self.file.readline(_MAXLINE + 1)
File "/usr/local/lib/python3.5/socket.py", line 571, in readinto
return self._sock.recv_into(b)
socket.timeout: timed out
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/logging/handlers.py", line 972, in emit
smtp = smtplib.SMTP(self.mailhost, port, timeout=self.timeout)

(code, msg) = self.getreply()
File "/usr/local/lib/python3.5/smtplib.py", line 390, in getreply
+ str(e))
smtplib.SMTPServerDisconnected: Connection unexpectedly closed: timed out
I switched to port 587 and Google successfully authenticated. The messages were sent.

Gmail problem:
Not addressed here. See other answers about Gmail's app authentication.
Verizon problem:
Some mail submission servers may only accept SMTPS on port 465. See What is the difference between ports 465 and 587? for elaboration. The Verizon mail submission server smtp.verizon.net, is one such example.
SMTPHandler does not support SMTPS by default. You can monkeypatch the functionality.
Solution:
This forces any server to use SMTPS.
A more thorough fix would be to edit the class with a flag to enable SMTPS.
Paste the edited emit function from below, into the relevant file.
Then set it
logging.handlers.SMTPHandler.emit = emit
The default /logging/handlers.py logging.handlers.SMTPHandler.emit function

Sending an email using smtplib via python

I am using mailtrap as the smtp server to send emails. However, when I send an email, I receive an error. The log in credentials are correct and I changed the emails for privacy concerns. Note, I am running this on a pycom device directly connected to my laptop.

Unable to send mail using smtplib in python

I am running the below code in Ubuntu OS. When I run this code in stand alone machine, I am not getting any error.
But when I connect the remote machine and run the same code, I am getting the following error message.
I have also modified the port value and try multiple times but the issue is not fixing. I am wondering where i need to check to resolve the issue.

Getting SMTPServerDisconnected error sending email through python

When trying to send the email with the host:cpanel.freehosting.com
P it is raising an error like
This is my code:
import smtplib
s = smtplib.SMTP('cpanel.freehosting.com', 465)
s.starttls()
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
This is the error i got:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/smtplib.py", line 251, in __init__
(code, msg) = self.connect(host, port)
File "/usr/lib/python3.5/smtplib.py", line 337, in connect
(code, msg) = self.getreply()
File "/usr/lib/python3.5/smtplib.py", line 393, in getreply
raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed
Considering the port number you are using I'd try with SMTP_SSL instead of SMTP and starttls().
https://docs.python.org/3/library/smtplib.html:
An SMTP_SSL instance behaves exactly the same as instances of SMTP.
SMTP_SSL should be used for situations where SSL is required from the
beginning of the connection and using starttls() is not appropriate.
If host is not specified, the local host is used. If port is zero, the
standard SMTP-over-SSL port (465) is used.
STARTTLS is a form of opportunistic TLS, it is supposed to be used with old protocols, that originally did't support TLS, to upgrade the connection.
The port 465 was used before the introduction of STARTTLS for SMTPS, which is now deprecated.
import smtplib
s = smtplib.SMTP_SSL('cpanel.freehosting.com', 465)
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
Alternatively you should be able to use port 25 with your original code.
import smtplib
s = smtplib.SMTP('cpanel.freehosting.com', 25)
s.starttls()
s.login("myusername", "mypassword")
message = "Message_you_need_to_send"
s.sendmail("myemailid", "receiver_email_id", message)
s.quit()
In both examples you can completely omit the port number as you are using the default ports.

Send email from server python

I am trying to send an email form my server with python, I asked my server provider what port to use for this and they said "choose SMTP Ports 465 (Secure SSL/TLS outgoing server) , 25 ( Non-SSL outgoing server)." Not sure what this exactly means but currently I am using 25, here is my code
#! /usr/bin/python
import smtplib
import smtplib
server = smtplib.SMTP('smtp.gmail.com', 25)
#Next, log in to the server
server.login("youremailusername", "password")
#Send the mail
msg = "\nHello!" # The /n separates the message from the headers
server.sendmail("you#gmail.com", "target#example.com", msg)
I filled in my username (which is my email address right) and password,a dn the target but it is not working, when I try to navigate to the url where my py script is, it just doesn't load. I have an internet connection cause I am loving other things, and go to other pages on my server. I have also tried running with cron jobs but that also doesn't work.
The permissions on the script are 0755, is there a problem with the script?
When i ran with cron jobs here is the traceback
Traceback (most recent call last):

Thanks for the help in advance.

BUG:
First of all you are using gmail server not your company server to send mail .For gmail server the output port is 587
The code:
Due to security issues gmail blocks accessing mail via code or program
But still you can use gmail to send mail via code if you do the following things
What i have done in code :
1.Added a error object to get the error message
import smtplib
try:
server = smtplib.SMTP('smtp.gmail.com', 587)
#Next, log in to the server
server.login("youremailusername", "password")
#Send the mail
msg = "\nHello!" # The /n separates the message from the headers
server.sendmail("you#gmail.com", "target#example.com", msg)
print "Successfully sent email"
except smtplib.SMTPException,error:
print str(error)
print "Error: unable to send email"
If u ran this code u would see a error message like this stating that google is not allowing u to login via code
Things to change in gmail:
1.Login to gmail
2.Go to this link https://www.google.com/settings/security/lesssecureapps
3.Click enable then retry the code
Hopes it help :)
But there are security threats if u enable it
Updated
import smtplib
try:
content = 'test'
mail = smtplib.SMTP('smtp.gmail.com',587)
mail.ehlo()
mail.starttls()
mail.login("ABC#gmail.com", "password")
mail.sendmail("ABC#gmail.com", "recivermailaddress", content)
mail.quit
print "Successfully sent email"
except smtplib.SMTPException,error:
print str(error)
In python, please download yagmail (disclaimer: I'm the developer):
pip install yagmail
It is then simply a matter of:
import yagmail
yag = yagmail.SMTP("you#gmail.com", "password")
yag.send("target#example.com", 'This is the subject', 'Hello!')
I guess it mostly just has to do with the fact that you gave a wrong port (smtp.gmail.com is not at 25).
On the github you can also see a common list of errors.

Emailing smtp with Python error

I can't figure out why this isn't working. I'm trying to send an email from my school email address with this code I got online. The same code works for sending from my GMail address. Does anyone know what this error means? The error occurs after waiting for about one and a half minutes.
import smtplib
FROMADDR = "FROM_EMAIL"
LOGIN = "USERNAME"
PASSWORD = "PASSWORD"
TOADDRS = ["TO_EMAIL"]
SUBJECT = "Test"
msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n"
% (FROMADDR, ", ".join(TOADDRS), SUBJECT) )
msg += "some text\r\n"
server = smtplib.SMTP('OUTGOING_SMTP', 465)
server.set_debuglevel(1)
server.ehlo()
server.starttls()
server.login(LOGIN, PASSWORD)
server.sendmail(FROMADDR, TOADDRS, msg)
server.quit()
And here's the error I get:
Traceback (most recent call last):
File "emailer.py", line 13, in
server = smtplib.SMTP('OUTGOING_SMTP', 465)
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 239, in init

self.sock = self._get_socket(host, port, self.timeout)

return socket.create_connection((port, host), timeout)
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/socket.py", line 514, in create_connection
raise error, msg
socket.error: [Errno 60] Operation timed out
It's likely that your school's SMTP server does not permit outside access to port 587. Gmail does, and requires authentication to ensure that you are who you say you are (and so that spammers can't send email appearing to be from you unless they know your password). Your school may have chosen to set up their mail server so that only connections from within the school can send mail in this way.
