Yesterday I got a question about whether it's possible to import a whitelist, or safe senders list, into FPE. In the FPE docs there are instructions for Creating an allowed senders filter list.
You can import items into the list. See Importing items into a filter list.
Added 2/10/2011: This isn't directly related, but there is a nice video that discusses filtering in general, here, at Filtering in Forefront Protection 2010 for Exchange Server.
Maybe I'm crazy. But don't see either the export or import selection.
I am using Forefront Protection 2010 for Exchange Server. It's installed on my Edge server. I edit an existing filter. nothing. What am I missing?
Hard to tell without seeing what you're seeing.
You can start a support case here: support.microsoft.com/.../14783
The cases are routed to our support folks.
The following video shows the steps for creating filter list and shows the import process:
Hope that helps.
