If you're talking about within the code... It knows the mailbox by the IMAP socket connection, which is in the $IMAP object, specifically: $IMAP->get_mailbox_name() which will changed based on what mailbox is selected.

when someone goes to view a message from either thier inbox or sent items, it goes through /steps/mail/show.inc, my question, is there a way to know which mailbox that message resides in?

Thanks
