I am using GFI MailEssentials on Exchange 2003 but I can't seem to configure the GFI or the Exchange so that e-mails to non-existent users gets deleted

I am using GFI MailEssentials 12 on Exchange 2003 but I can't seem to configure the GFI or the Exchange so that e-mails to non-existent users gets deleted automatically.  (in GFI, I have most of my filter settings set to "delete" except Bayesian Analysis and "DNS Blacklists", which were set to forward to a  bogus mail box for review for before final deletion.)   I can't seem to stop receiving mails from non-existing users!

What do you recommend for tarptime?  what do you set yours to be (if applicable)
I use 5 seconds.  It's just something to stop a spamming server trying lots of random addresses (e.g. aaa@domain.com, aab@domain.com, aac@domain.com, etc.) each second, in order to discover the valid addresses.  Now they are only be able to try one address every five seconds, instead.
