Thank you NTozier.But I still have some questions.I unticked "Accept Email collaborators".1.) But should I not leave "Accept All Emails" as is, so ticked? Because I want every customer and people who want to become customer, to be able to send an email to the support ticket system.Won't unticking Accept all Emails disable this possibility?2.) The "Accept Email Collaborators" says it does this "
Automatically add collaborators from email fields", so unticking this is good.Am I correct that when a user creates a ticket, he can't add collaborators anymore either after he logs in?
