I saw T6819 and understand it's related, but I think our use case here might be a little different.
We would like to have a flow where any user can send an email to special_email_address@dropbox.com, and have a new task created with the appropriate, pre-defined tags -- maybe similar to using a template to create a new task. The reason we have this ask is because the user submitting the request will not have knowledge of the appropriate project, subscribers, etc necessary for the task, but all emails going to that address will belong in the same project, have the same subscribers, etc.
It looks like we are capable of setting up application emails, but then they fall into a black abyss with no project, subscribers, tags associated.
Let me know if this is an education issue on my part! @devd can provide more details if necessary.
