Sendmail python

Sendmail is a popular email transfer agent (MTA) that can be used to send emails programmatically from a Python script. Here's a step-by-step guide on how to use sendmail with Python:

Prerequisites

1. Install the sendmail package on your system. On Ubuntu-based systems, you can install it using sudo apt-get install sendmail.
2. Make sure you have Python installed on your system.

Sending an email using sendmail with Python

You can use the subprocess module in Python to execute the sendmail command and send an email. Here's an example code snippet:

import subprocess

# Set the email details
from_addr = "[email protected]"
to_addr = "[email protected]"
subject = "Test email from Python"
body = "This is a test email sent from Python using sendmail."

# Set the sendmail command
cmd = f"sendmail -t -i -f {from_addr} {to_addr} << EOF"
cmd += f"Subject: {subject}\n"
cmd += f"{body}\n"
cmd += "EOF"

# Execute the sendmail command
subprocess.run(cmd, shell=True)

In this example, we're using the subprocess module to execute the sendmail command with the following options:

• -t: Tells sendmail to read the email message from standard input.
• -i: Enables the use of internationalized email addresses.
• -f: Specifies the sender's email address.
• << EOF: Marks the end of the email message.

The email message is constructed by concatenating the subject, body, and other headers using the f string notation.

Note: Make sure to replace [email protected] and [email protected] with your actual email addresses.

Additional tips

• You can customize the email message by adding additional headers or attachments using the sendmail command.
• If you're using a Linux system, you may need to specify the full path to the sendmail executable if it's not in your system's PATH.
• Be aware of any email sending restrictions or limitations imposed by your email provider or organization.
