My Mautic version is: 5.1.0
My PHP version is: PHP Version 8.1.2-1ubuntu2.19
My Database type and version is: 10.6.18-MariaDB-0ubuntu0.22.04.1
With doctrine I can only send about 160 emails per minute, which is not enough. I installed and configured RabbitMQ on my server, but when I enter “RabbitMQ” in the Scheme field at Queue Settings, this error message appears:
`Unsupported scheme. Please make sure the entered scheme matches one of the supported schemes. You might need to install a package supporting the scheme first. For more details see https://symfony.com/doc/5.4/messenger.html#transport-configuration`
I’ve read that section at the Symfony docs which suggest that I would need to install `amqp-messenger`, but that would require me to mess with Mautic’s code, and I’m not sure if that is necessary considering that Mautic supposedly supports using RabbitMQ already.
What do I have to enter in that box?
Thank you 🙂

Here’s the solution:
Scheme: `ampq`
Host: `localhost`
Port: `5672` (RabbitMQ default)
Path: `/`
To make this work, I had to install the package `php-amqp`.
By operating 10 systemd service workers running `messenger:consume`, I could increase the throughput to 1200 emails per minute. That’s on 4 vcpus and 16gb ram.
