I set up an incoming email address for a Trello list. I use it for QA testers to submit bugs directly to a New Bugs list we created. I noticed when the sender has an account on the Trello board (member of team), Trello auto-assigns the new card to that person. I don't want to do that. I use member assignment of cards for the person who's responsible for working on the task, not the person submitting the issue. Is there a way to prevent the auto-assignment?
