There is no setting in MSOE to affect this. There are two basic reasons for
not getting a delivery failure notice. If you mistype an email address, but
it is a valid email address in the domain, your message will be delivered to
the address. Say you send mail to <mikey@example.com>. If you mistype that
as <mikeey@example.com>, it may bounce if "mikeey" doesn't exist at
example.com; it won't bounce if "mikeey" does exist at example.com.

If example.com accepts all email, then tries to figure out if it can deliver
the email, failure delivery notices with go to the "Return-Path:" email
address. So much spam forges that email address that something called "back
scatter" as become a problem; "back scatter" is misdirected email; bounces
and virus blocked announcements going to forged email addresses. The problem
is getting so bad that many email services are no longer bouncing email at
all.
