I have one user that constantly says he didn't receive an email from some one the first time they sent it but it arrived the second time. If i get the message headers and do a track on the server, it shows as delivered.
He also complaints that email from certain internal users always arrives on his junk e-mail folder even after he clicks on "Not junk"
I have had him add the users to the "Safe" senders list but I don't think internal addresses can be added here. His rules also, seem ok.
Any ideas what it's going on?
