We have a 2003 Exchange\Outlook 2003 environment downstream from a corporate Domino environment. Domino and Exchange users both have the same "1234@XXXXX.com format. We have an SMTP address "email@example.com" that we use to send out notices from an inhouse app through a corporately hosted private SMTP server. This address occasionally gets directed to the end user's junk email folder. After it happens, even if I change that user's client to "add to safe senders list" it still is misdirected. Any way to hardcode this at the exchange level to get past this issue?
