Keith, Best thing to do, when a person leaves the company (or otherwise is no longer issued a mailbox) is to leave the mailbox active for awhile and unsubscribe from any mailing lists, newsletters, etc that are 'real' (non spam)... That way those incoming messages aren't stealing your incoming bandwidth any longer... Then, after you're sure that the mailbox is only recieving spam (no real email or unsubscribable mailing lists), remove the SMTP address from the mailbox and add the SMTP address to a distribution list with no recipients. When the mail comes into the SMTP address it gets distributed to 'nobody' and is effectivly removed from the system... It of course sill wastes incoming bandwidth and system resources to recieve the message (I don't think anyone has figured out how to get around that yet) but at least it doesn't generate an NDR are clog up the admin box with garbage...

Our mail comes through our firewall and is sent to an OWA box acting as a smtp relay/filter before being sent to the E2K Cluster. Now the question we have can you filter out old mailbox receiptiants that dont have mail boxes anymore. All undelivered mail that is NDR is sent to a Mail Box just incase of spelling mistake, but it also collects all NDRs from users that have left, but are still subcribed to mailing lists and some undisired messages. We also have NAI's Webshield, but like GFI the filters can be set for a keyword or mail domain not for ie user@xxxxxxxxxxxxx a user for home we dont want to recieve email.
