How can I write a python plugin for an mail client Evolution

[kocmohabt228]

I need to write a mail plugin Evolution 3.32.4-alt1 preferably in python. Plugin functionality: If the user sends an email not to the organization’s domain, then a dialog box with a warning about this and the “Cancel” and “Send” buttons should be displayed. How can this be implemented? How to make Evolution recognize the plugin?

As per knowledge, it's very simple-
Follow these steps-

1. Install Required Packages

Code: Select all

sudo apt-get install evolution-data-server-dev python3-gi

2. Write the Plugin Code:

Create a Python script for your plugin (https://packaging.python.org/en/latest/ ... g-plugins/).
Let's call it 'org_domain_warning.py':

Code: Select all

#!/usr/bin/env python3

from gi.repository import GObject
from gi.repository import Camel
from gi.repository import Evolution

class OrgDomainWarningPlugin(GObject.Object, Evolution.MailFilter):

    def filter(self, filter_str, message, user_data):
        # Extract recipient email addresses
        recipients = [addr.get_address() for addr in message.get_recipients()]

        # Check if any recipient is outside the organization's domain
        if any('your_organization_domain.com' not in recipient for recipient in recipients):
            # Display warning dialog
            dialog = Evolution.Dialog(
                'Warning',
                'You are sending an email outside the organization\'s domain. Are you sure you want to proceed?',
                Evolution.DialogFlags.MODAL | Evolution.DialogFlags.NO_SEPARATOR,
                Evolution.STOCK_DIALOG_WARNING,
                Evolution.Button('Cancel', Evolution.ResponseType.CANCEL),
                Evolution.Button('Send', Evolution.ResponseType.ACCEPT)
            )

            response = dialog.run()
            dialog.destroy()

            # If the response is 'Cancel', stop sending the email
            if response == Evolution.ResponseType.CANCEL:
                return Evolution.MailFilterResult.STOP

        # Continue sending the email
        return Evolution.MailFilterResult.CONTINUE

# Register the plugin
GObject.type_register(OrgDomainWarningPlugin)
Evolution.MailFilter.register_type(OrgDomainWarningPlugin)

3. Install the Plugin:

Code: Select all

sudo cp org_domain_warning.py /usr/lib/evolution/3.32/plugins/

4. Test the Plugin

I followed the same steps while I was create Plugin functions for this DevOps model.
