I want to turn NDR's off. Is it a POP3 function or an SMTP function?? Is
there a registry hack for this because I can't find any settings for it. I a

possible??
Thanks

Thanks Bernard
I was aware that Exchange has the option but no where did I see mention of
it in IIS. I feel better that someone else is of the same opinion.

I will share with everyone what I have done in the hopes maybe this will be
useful for someone else.

I downloaded the "CatchAll" scripts from ilopia
-http://isorecorder.alexfeinman.com/catchall.htm

I setup an email called junk@ and ran the CatchAll script so that all emails
not going to a valid address would end up in the junk@ account.

I setup Outlook Express on the server to download and delete the messages.

It ran all night and no emails in the queue and none in the badmail folder.
For me this was a big problem because it looked like I was being attacked by
the reverse NDR problem I have read about. Over several weeks my badmail
folder became so full it crashed the smpt server.

Here is a great site about the Reverse NDR issue
http://www.cmsconnect.com/Praetor/RNDR/RequestCheck.htm

Just to note a better way to fix this is get a spam service like
www.spamstopshere.com. Have them scan your email - then forward it to you.
Get a firewall that will allow you to filter IP's on specific ports so that
you can lock down port 25 to a handful of IP's from the spam service. This
way nobody other than your spam service can get to your mail server. I have
all this in place except the firewall that allows me to filter IP's for
specific ports. The service doesn't forward emails that come in for my domai
n
that are not valid so no NDR's are produced from my server. The spam service
works great but they can't stop the 1% of spammers that get my mail server M
X
record and get to me directly. Just a note if my server goes down they hold
email for up to 5 days - pretty cool feature. All for about $100 bucks a yea
r.


Hope this is helpful!!

The problem seems to have been fixed. I Updated Outlook to the newest SP and
it started working correctly. There must have been an update to the way SMTP
Auth is handled with IIS6 in Outlook 2000 SP 3

Thanks again for all the help

Is this refer to your other post ?
if yes, that make sense, it's client issue rather than server.

Bernard - Yes to answer your question this does refer to my other post -
"SMTP 550 5.7.1 Unable to relay". I guess in the excitement that it worked I
inadvertently posted to the wrong thread. Thanks for bringing to my attentio
n
and sorry for any confusion.
