Intermittent Exchange 2007 NDR
Hello Experts:
One user is receiving errors like this from one or two senders each day. Attachments are usually involved but are small (usually under 5 MB)
System is SBS 2008, content filtering is off. SMSE 6.5 is not trapping the messages in quaratine.
The IP w.x.y.z in the error is the static IP of the SBS box.
I have checked and they are not blacklisted.
Any idea what could be causing this error ?
Thanks

Make sure the users cached contact list does not have any misspelled email addresses, if so delete from suggested contacts.
