I'm trying to send emails using python smtp library but get the following an error message when trying to send to external email addresses (internal email works):
smtplib.SMTPRecipientsRefused: {'test#gmail.com': (550, ' Relaying denied')}
This is because we have rules setup on our exchange that prevent relaying from client machines.
What I don't understand is how come I can send emails over SMTP with an SSIS package without getting the relay error.
Is there a setting I need to enable in my python to bypass this or is SSIS sending the email to SQL Server to send on its behalf.
I believe you are getting this due to authentication. SSIS is probably passing your windows credentials through but when you are trying to send with python your credentials are being denied.
Not 100% sure that is your issue. But a thought.

Currently we have a postfix relay Linux server hosted on GCP and it is connected to proofpoint.
My Python application is on another vm. I am wondering how can I setup my app to send out email using the postfix relay server?
For example, mailgun provides smtp credentials or api keys. The credentials can be used in application for authentication and send out emails.
Any feedback is appreciated
We are using Elasticemail for our SMTP server and running in issues where our server would fail to connect to the SMTP server for various reasons. Currently, we only find out about the issue when a user complains.
We want to monitor the connection to the server on a regular interval and notify Admin if there is a connection failure.
Is there any way to test the connection to the server without sending an actual email using Python3?
I have created a Python application to send emails. I am running Python 3.8, Postfix, and Opendkim all on the same Ubuntu 20.04 machine. I have successfully configured Postfix and Opendkim to sign outgoing emails. My Python script is using smtplib to send the emails. This portion is working as expected, and all emails sent from this Python application are signed by Opendkim.
Now, I have created a web API using Flask to send emails. I send some json with a post request to the end point, and the Flask application sends an email. Outside of using Flask, this setup is identical to the one outlined above. Emails do send, but they are not being signed by Opendkim. Emails sent with a Python script running from the terminal on the same machine that the Flask application is running on are getting signed by Opendkim. So, I know that Postfix and Opendkim are working, it just does not want to sign an email originating from the Flask application.
I cannot figure this out. Flask is running on 127.0.0.0.1:5000. I have also tried running it on 0.0.0.0:5000. I have tried sending post requests using a Python scrip running on the same machine. They all work, in that an email is sent, but i cannot get Opendkim to sign them.
Any help would be appreciated.
How can you send an email from a Databricks platform?
I would like to send an email from a notebook in Databricks with Python. I'm wondering if there's already an SMTP client already configured that I can use. I tried to do it, but didn't succeed.
The answer is "no". There's no smtp client included in Databricks.
But you can define yours outside and use it through the Databricks platform.
How can I sendmail from Python 2.4 without any password authentication?
Look at the smptlib example:
http://docs.python.org/library/smtplib.html
There is no documentation telling you that authentication would be mandatory.
Authentication is optional.
You need to configure your mail server to allow unauthenticated relaying from the IP running your python code (e.g. 127.0.0.1 if it's the same system).
However, ensure that you do not allow relaying for the world - otherwise your server will be throwing SPAM emails around and get blacklisted for it soon.
