Ticket System with Taskboard

hello everyone,

I would like to deploy a ticket tool which i can connect with a email mailbox so people can send a email to support@example.com to create a ticket. Also no login requirement would be essential.

Currently im working with Github Projects as Taskboard, so it would be nice to create Tasks from a ticket in the system or in github via integration.

Does anyone know something like this? It should be kinda simple, nothing big

Thanks everyone!
