I have just sent to the list the complete thread with Microsoft until now, hopefully it properly replied to this thread. My understanding of Microsoft's reply is that there is nothing wrong with the server / IP / reputation. Their reply point to a content filter at work. > Generally, the simplest solution is for the correspondents to add > your email address to their contact lists, send you some email, ... > and thereby indicate that your email is wanted by them. If I could exercise that level of control on my clients, I would direct them to a non-Microsoft service. There are a bunch of other problems with contact lists on free email services. Bottom line is that it is not a practicable solution in my circumstances, and further discussion would detract from the main issue which is "silently discarded emails," I behavior that in my view is plain wrong and threatens the usefulness of email more than a few false positive spam messages.
