Microsoft Outlook 8.5 and earlier, and Outlook Express 5 and earlier, with the Automatically put people I reply to in my address book option enabled, do not notify the user when the Reply-To address is different than the From address, which could allow an untrusted remote attacker to spoof legitimate addresses and intercept email from the client that is intended for another user.
