Bruce,
Thanks for the reply, but I think you might have missed the issue. We don't want to use the content filtering for spam control. I agree that would be a massive headache and fairly ineffective. We have some applications that send out a lot of automated messages (logs, events, etc.). We'd like to be able to organize those as they come in to subfolders and keep them out of the main inbox. These messages are sent out from an authenticated user and it appears that bypasses the filtering rules. I'm not sure if this is by design or is configurable somewhere.
Thank you.
