I have the same problem but since my phone was perused I can't log into my BIS bc it seems to be under another username and password. Is there an easy way to get around it?

Where do you go into your email setup to set this filter?
Log in to your BIS account and you should see a button (or something similar) named "Filters" next to the email account you want to edit. Click it and you should be able to set up the filter.
