In a python script, I have the following:
with smtplib.SMTP_SSL(sender_server, 465, context=context) as server:
server.login(sender_email, sender_password)
server.sendmail(
sender_email, email, message.as_string()
)
On the Windows machine I wrote the script on, everything works as expected and the email is sent and delivered without issue. However, when I try to run the same code on my Linux VPS, a TimeoutError is thrown every time.
Traceback (most recent call last):

TimeoutError: [Errno 110] Connection timed out
What could be causing this difference? My Google searches didn't bear much fruit, but maybe I'm just searching for the wrong terms.
TimeoutError: [Errno 110] Connection timed out
This means that access to the remote system is likely blocked somewhere on the way to the system. Given that you have this problem on a "Linux VPS" it is likely that the connection is blocked by the company hosting this VPS or that you need to configure your machine specifically to allow such access. Check with your specific hoster and its documentation.

I am attempting to set up a script that will fire off a series of emails automatically.
Below I have the code I am using to test this process.
import smtplib, ssl
username = 'me#company.com' # input('Enter username: ')
password = 'mypassword' # input('Enter password: ')
port = 443
smtp_server = "outlook.office365.com"
sender_email = username
receiver_email = "me#company.com"
message = "Hi there! This message is sent from Python."
context = ssl.create_default_context()
# s = smtplib.SMTP_SSL('outlook.office365.com')
# s.set_debuglevel(1)
with smtplib.SMTP(smtp_server, port) as server:
server.starttls(context=context)
server.login(username, password)
server.sendmail(sender_email, receiver_email, message)
When I run it, I get the following error:

I want to send the email from Outlook specifically.
Checking the 'Accounts' settings I see my server is running on port 443 and has a domain of https://outlook.office365.com/subdomain/Exchange.asmx
I'm only using the outlook.office365.com portion of it since that's all that is shown in most examples I see. However I have tried using the full domain as well as just https://outlook.office365.com/. Nothing seems to work.
I have been using the info found here to guide me.
Originally I was using the domain smtp.office365.com but changed it after finding outlook.office365.com in my accounts settings. It fails with the same error anyway.

I also tried with port 587 rather than 443. (443 is what I find in my outlook settings) - same error either way.
Update: I think the answer to my question is that mac's don't use SMTP...now I have to figure out how to do this in IMAP.
What protocol does Outlook for Mac use?
By default, Outlook is set to IMAP protocol. If you choose to set your account on IMAP, you may use the following settings then click Add Account.
Additional Update:
I ended up scratching this approach altogether. I ended up using an internal API service to send notifications out to all relevant parties.
For Office 365 accounts, the SMTP server name is smtp.office365.com, post 587, TLS on.
I was having previously an issue where I was getting ValueError: server_hostname cannot be an empty string or start with a leading dot. Checked this post in Stack Overflow and when I followed the instruction and run in the console:
import smtplib
smtplib.SMTP_SSL(host='gmail-smtp-in.l.google.com').connect(host='gmail-smtp-in.l.google.com', port=25)
but I am getting a time-out as per below error:

I get the issue only when I enable in my code server.starttls(). If this is commented out, it can send email fine.
Below is a snippet of my code:
server = smtplib.SMTP_SSL()
server.connect('gmail-smtp-in.l.google.com', 25) # mail server want to connect to.
server.set_debuglevel(True) # shows communication with the server in the console
server.ehlo()
server.starttls()
server.ehlo()
maybe you could try using python 3.9. I dont know what operating system youre using but if youre using mac you have to use pip3 instead of pip so python can understand it (mac has python 2 as default) Hope i could help :)
Input
import smtplib
conn = smtplib.SMTP('imap.gmail.com',587)
conn.ehlo()
conn.starttls()
conn.login('loginmail#gmail.com', 'password')
conn.sendmail('sender1#gmail.com','sender2#gmail.com','Subject: What you like? \n\n Reply Reply Reply')
conn.quit()

Please help me to solve this issue. It looks like server issue. I have included the login mail and password, 2 sender emails and a subject. I want to send a zip file. The program is showing error and I have provided the error above
You are connecting to the wrong server. Should be:
conn = smtplib.SMTP('smtp.gmail.com', 587)
I am try to send email in my django project using Celery and RabbitMQ.

I had exactly the same problem, but I solved it by setting up my settings.py just like skulegirl says, and just add this to my settings.py
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
I hope it helps you.
Your code repo is configured to use the console backend for emails, but your backtrace is showing the smtp backend is being used. I assume you've changed the backend and that's what's causing the error.
By default, the smtp backend looks for an smtp server on localhost. I'm guessing you don't have one running there.
If you want to send via gmail's smtp servers you can do so, you just need to configure the approriate settings in your settings.py file. See the django docs for what needs to be configured. Read the gmail docs for the exact smtp host address to use.
I have a server built in python, using Tornado and RethinkDB. Its been running for a long time, opening several connections to the DB per user. I never had any major problems by leaving them open -never closing them-. But checking out the log file I found out there's a lot of this warnings:

Should I worry about it? In that case, what are the good practices?
Yes, you need to close the connection to avoid connection leaks. This Flask example, from RethinkDB, does it:
https://github.com/rethinkdb/rethinkdb-example-flask-backbone-todo/blob/master/todo.py#L47-L65
Even if RethinkDB does not enforce a hard limit on number of connections (I'm not sure if it does or not), you can run into the limits of the OS.
