I posted a reply but it did not show up so I will try again.
I have tried this toggler and it does not seem to do what I thought it did
from articles I have read. The Help system and articles make it sound like
it will filter out e-mail to addresses that do not exist in your active
directory but this does not seem to be the case or at least not on my
servers. I have 2 Exchange Server 2003 servers receiving e-mail. On both,
the Recipient Filters has been turned on and I have enabled the "Filter
Recipients who are not in the Directory" toggle. My Exchange Servers still
process all inbound mail to any alias for my domain name.
I am trying to get our servers to only process valid addresses in our AD and
to just ignore anything else. I am currently getting about 200 to 300 NDRs
a day from spammers to non-existant addresses. This is already with
Real-Time block lists enabled from SPAMHAUS and DNSRBL which are working. I
would only like to receive valid NDRs for outbound mail problems and inbound
for existing addresses. Am I mis-understanding the use of this toggle
completely? There has to be a way to just totally ignore these e-mails. I
recognize that I might miss valid e-mails with mis-typed aliases but at this
point in time, I really don't care. These undeliverables are driving me to
insanity.
Any suggestions would be appreciated.
Thanks
