Sort incoming mail into folders in a shared mailbox?

Hi Experts,
I am the owner of a shared mailbox in my company. We are using Exchange2010.

I have a couple of support staff that gets problem notifications sent to this mailbox.

I would like to be be able to make rules in this shared mailbox to sort mail as it
comes in into different folders.

I have a lot of these kind of rules in my Outlook client and I though the same could
be done on a shared mailbox, but now my Exchange administrator says it can't be done.
Is that really correct?

Basically I want mails sent från system A (A[AT]abc.com) to be sort in folder /A in the
shared mailbox.

Of course I could create a specific shared mailbox for system A. But I rather just sort
the incoming mail in subfolders for serveral reasons. Isn't it possible?
