What is the difference between "adding message" and "delivering message"? I've got a user that isn't receiving any emails from a particular vendor. When we look in the log files it shows "adding message" (for those missing emails), but it doesn't end up in the user's inbox. If we send a different user a message from a hotmail account, the log file shows "Delivering message" and it comes into the inbox. Any ideas?? Below I've listed some of the log entries. The "good" log entry is first, followed by the "bad":
