How can I retrieve incoming emails using Mailgun?

I’m trying to set up a system where I can track emails sent through Mailgun. Here’s what I’m doing:

  1. I send an email from address A to address B using Mailgun.
  2. When B replies to A, I want to catch that incoming message.

I’ve set up a route in Mailgun to forward messages to a Gmail account, but it’s not working. Here’s a simplified version of my code:

# Sending email

def send_email():
    smtp_server = SMTP('smtp.mailgun.org', 587)
    smtp_server.login('[email protected]', 'mypassword')
    smtp_server.sendmail('[email protected]', '[email protected]', 'Subject: Test\n\nHello!')
    smtp_server.quit()

# Setting up route

def setup_route():
    route_data = {
        'priority': 1,
        'description': 'Forward emails',
        'expression': 'match_recipient(".*@example.com")',
        'action': 'forward("[email protected]")',
        'action': 'stop()'
    }
    requests.post('https://api.mailgun.net/v2/routes', auth=('api', 'my-api-key'), data=route_data)

Am I missing something? Why isn’t the forwarding working? Any help would be appreciated!

I’ve faced similar issues with Mailgun routing before. Here’s what worked for me:

First, double-check your route configuration. Make sure the expression matches the exact domain you’re expecting emails for. Also, ensure your API key has the necessary permissions to create routes.

Next, verify that your forwarding address ([email protected]) is properly authenticated with Mailgun. Sometimes, this step is overlooked.

If that doesn’t solve it, I’d suggest using Mailgun’s ‘store()’ action instead of ‘forward()’ initially. This way, you can confirm if Mailgun is actually receiving the emails. You can then retrieve them using the messages API.

Lastly, don’t forget to enable and properly configure your Mailgun receiving domain. This is crucial for inbound email processing.

If you’re still stuck, Mailgun’s logs can be incredibly helpful for troubleshooting. They often reveal issues that aren’t immediately apparent in the code.

hey there! have u tried using webhooks instead of forwarding? it’s way more reliable. just set up a simple endpoint on ur server to receive POST requests from mailgun. then u can process the incoming emails however u want. it’s pretty straightforward and works like a charm!
