Thank you guys. I was prone to using MailCow or iredMail and now I consider Post as a priority. Is it still the best option? ---

If you can manage your own IPs, Postal is a dream. ---

> [@joeyk](#): > > feedback loop is `yourmautic.com/mailer/postal_api` For those that are dealing also with the topic, the return path in Postal is: `https://yourmautic.com/mailer/postal_api/callback` I created a Webhook that deals MessageDeliveryFailed messages (and also MessageBounced). Unfortunately the contact is not set as bounced in Mautic. Could it be that Postal v2.1.4 (28.04.2023) has changed this part after the Plugin [GitHub - LucasCCS/postal\_server\_api\_transport\_for\_mautic](https://github.com/LucasCCS/postal_server_api_transport_for_mautic/) was created (1.12.2021) ? The Payload that is sent from Postal is: > { > “message”: { > “id”: 40, > “token”: “Mk…mW”, > “direction”: “outgoing”, > “message\_id”: “[dbe...4b7fc78@rp.io.ionutojica.com](mailto:dbe...4b7fc78@rp.io.ionutojica.com)”, > “to”: “[testarea-bounce4@ionutojica.com](mailto:testarea-bounce4@ionutojica.com)”, > “from”: “[contact@ionutojica.com](mailto:contact@ionutojica.com)”, > “subject”: “test twig2”, > “timestamp”: 1694125749.090986, > “spam\_status”: “NotChecked”, > “tag”: null > }, > “status”: “HardFail”, > “details”: “Permanent SMTP delivery error when sending to [ionutojica.com](http://ionutojica.com) (198.20.108.202)”, > “output”: “550 No Such User Here\n”, > “sent\_with\_ssl”: true, > “timestamp”: 1694125789.5417223, > “time”: 20.1 > } > [@joeyk](#): > > We are using our own feedback loops.

Hello, I actually have the same problem. I’ve looking for a way to handle bounce emails from Mautic using Postal. I installed the `postal_server_api_transport_for_mautic` package from Github that you recommended and now I can send emails with Postal using API. I also made a Web hook and set up the URL to be: `https://mauticserver.com/mailer/postal_api/callback` and for Events I selected `MessageDeliveryFailed and MessageBounced` but when I send emails from Mautic to a “fake email” I dont gent the user marked as “bounced” Im not sure if there is an extra config that I need to do on Mautic or Postal to make this work. Thanks ---

Hello, can you start something with this? > > > The MessageDeliveryFailed and MessageBounced Webhooks (actually no Webhook) are …recognized by the plugin. > > I suppose that the actual Postal version 2.1.4 is using another encription and the function does not process the encription right: > > public function processCallbackRequest(Request $request): void It works, unfortunately the solution is not implemented in the plugin on GitHub and I do not know how to implement it. It would be cool to have it implemented there, so that it would be available simply to download and works. Success ! ---

Hi, Thanks for the info. I tried that [Github repo](https://github.com/Pacerino/MauticPostalServerBundle) - Cloned the Repo - Ran `php mautic:plugins:reload` - Setup Postal SMTP on Mautic - Included the DKIM key on the config file - Made the web hook on Postal like `https://mauticServer.com/mailer/postal/callback` Still bounce emails doesn’t work, and my web hook on Postal give me a 500 Error. Im using `Postal 3.3.3` and `Mautic 4.4.12` I saw on the repo that the plugin was tested on Postal 2.x so Im not sure if it wont work on Postal 3.x Is there any change that I missed? ---

It is not enough to clone the Repo, as the improvements to make the bounces to work are not implemented, but are explained in the mentioned Issue. Can you use this one, as I have made the proper changes as I use the plugin: > **[GitHub - IonutOjicaDE/MauticPostalServerBundle: Plugin for Mautic to use...](https://github.com/IonutOjicaDE/MauticPostalServerBundle)** > > Plugin for Mautic to use Postal V3 as email transport - IonutOjicaDE/MauticPostalServerBundle ---
