I have a user with Outlook 2003 and Exchange 2003 experiencing a Junk email problem that I can't resolve reading like issues here.
The emails in question come from email@example.com, to firstname.lastname@example.org from 3rd party software run on a system on the same subnet as the Exchange server. To resolved, I have excepted the entire subnet from Content Filtering, removed the only RBL present in CF, added the address to the Safe Senders list, and turned off Junk email filtering. There are no rules setup. I have also setup the account on another machine to test (and close Outlook on the first) and it still goes to Junk. Message Tracking shows nothing unusual - just that the messages are delivered in the normal manner.
Anyone have any thoughts?
