I'm trying to avoid the huge numbers of NDRs that my Exchange environment is
currently processing for non-valid e-mail addresses.  I am running Microsoft
IIS SMTP 6.0 relay at my inbound Internet e-mail gateway.  I want to "reject
"
any e-mail at the gateway if there is no valid e-mail address in my Exchange
environment.  For example my e-mail address is jschmo@domain.com so e-mail
will be accepted for this address.  If an e-mail is sent to jjjjj@domain.com
(which does not exist in our environment) I want to reject or drop this
inbound e-mail at the gateway.  Is this something that can be accomplished
through using the LDAP routing feature for IIS SMTMP relay?  If so, are ther
e
clear instructions available on how to configure this w/ AD?
