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...

I am looking for ideas, we are trailing the GFI software at the moment
to filter spam in conjuction with a E2K cluster. 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.
