HowTo implement "delegated e-mailing"


i have a use case that i’d like to implement using Zammad, but i’m not sure if it’s feasible.

I want to use Zammad to track the communication between all of the tennants of our house and some contractors. I’d be the “delegate” that creates a Ticket in Zammad, send it to the contractor and provide access to the ticket to all intetested tennants in our house.

The problem is, that i’d also like to use Zammad for other purposes than this. That means, that i somehow would like to make tickets only visible for certain “groups”.

I’d like to restrict all tickets from different contractors to one “group of tennants”. Is that possible with Zammad?

Edit: accidentally published a draft

Bonus question: Would you setup the tennants as customer or agents?
