NDR Email Account Does not exist - Yet it does! 1

[dpazuk]

Lately I have received reports from various users that emails sent from outside our organization to some of our users are being bounced back with the following error message:

"The e-mail account does not exist at the organization
this message was sent to. Check the e-mail address, or contact the recipient directly to find our the correct address. 5.1.1"

These errors are being generated by our Exchange Box (we are running EXCH 2000 on WIN2K with all the latest service packs and GFI Mail Essentials 11, all on the same box).

Our reipient policies have remained the same, no changes there, yet despite the fact that our user email address and accounts do indeed exist within our AD, this error messages still occur.

I have read the MS KB article 284204 concerning this NDR, but everything on my Exchange server appears 'normal.'

Any ideas as to what could be causing this?

confirmed on user account profile?
correct smtp?
run RUS manually

if so then most likely look towards gfi...it may not be connecting to ldap correctly...

Yes "confirmed on user account profile?"
Yes "correct smtp?"

RUS? Pardon my ignorance, what is RUS and how do I do this?

As for GFI, I have it checking the AD directly and am not using ldap.

Recipients
|-> Recipient Update Service
|---->domain right click -update
but looking at user profile u would see if user has a correct default smtp address stamped.

not sure about GFI as it has been a while since I looked at it but see if u can resolve all users in domain through GFI console ( I am pretty sure they access AD throuhg ldap)
hate to do this but the best:

http://kbase.gfi.com/

on ecxhange side try querrying ldap and see if u can find that user etc...most likely all is well.
All the best!

I performed a manual update of the RUS.

Hopefully, this will help resolve the issue.

I have also set up Exchange to forward a copy of all NDR's generated by Exchange to my own inbox. This way I can more effectively monitor the situation.

Thanks for your helpful advice! Star well deserved!

thanks for the *
yes, def. keep an eye on NDRs but also don't hog them all as, after a while, you would want to either send them out or look them over to make sure that legit 'errors' are knows...such as someone misspelling the name etc.
Keep an eye on your logs and perhaps turn on some exchnage montioring
