Thanks for your quick reponse. I guess I find it a bit confusing to have an email address assigned to a department and emails that come to that address not be assigned to that department.
Now, on to fixing the problem.
I scoured the admin panel and could not find:
Admin panel -> Manage -> Ticket Filters
I couldn't find it under Dashboard, Settings, Emails, Help Topics, Staff or Departments.
Settings has: Preferences, Attachments and API
Emails has: Email Addresses, Add New Email, Templates, Banlist
Departments has: Departments, Add New Dept.
I've been through each of those screens and find no way to manage the filters. I must be missing something.
Again, this is version 1.6ST and I'm using Email piping.
