Mail.inline

mail.inline is a module in Python's email package that allows you to embed binary data, such as images or audio files, directly into an email message. This is useful when you want to send emails with attachments that are not text files.

Here's an example of how you can use mail.inline to embed a binary file into an email message:

import email.mime.multipart
import email.mime.application
import email.mime.text

msg = email.mime.multipart.MIMEMultipart()
msg['Subject'] = 'Test email with inline attachment'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'

body = email.mime.text.MIMEText('This is a test email with an inline attachment.')
msg.attach(body)

attachment = email.mime.application.MIMEApplication(open('path/to/attachment', 'rb').read())
attachment.add_header('Content-Disposition', 'inline; filename="attachment"')
msg.attach(attachment)

server = smtplib.SMTP('your_smtp_server')
server.sendmail('[email protected]', '[email protected]', msg.as_string())
server.quit()

In this example, we create a MIMEMultipart message and add a MIMEText part with the email body. We then create a MIMEApplication part with the binary data of the attachment, and add a Content-Disposition header to specify that the attachment should be displayed inline. Finally, we send the email using an SMTP server.

Note that when you send an email with an inline attachment, the recipient's email client will display the attachment directly in the email message, rather than as a separate attachment.
