Disable automatic contact creation for Conversations

PLEASE correct this issue for us. We use a Team Email for random inquiries, to accept purchase orders, etc. and it has also become a hub for spam outreach. Every single day, 10-20 spam / no-reply contacts are added minimum, and it is severely cluttering our CRM.

We simply want to turn off “auto-create contact” when someone emails a Team Inbox. If we want to create them, we can manually choose to do so. It has been three years since the Product Team indicated they were working on this -- can you please provide an update? Thanks so much!
