I'm not sure I completely understand your situation and what your problem is.
However, you should note that the RHEL-5 system might have delayed expunge
enabled which at least means that a mail delivered to an inbox and then
deleted from there will still be visible on the filesystem. Do you really
see the mail via IMAP or only on the filesystem?
