This is happening to a few users at our company. We are getting junk/spam email from ourself. We use Trend Micro virus protection on all our servers & deskstops. I also have Trend scanning the emails on the Exchange servers. For the most part in the past few years, we haven't seen very much junkmail (if we do - it's only a flurry for a day or two). However, now for about the past month, several of us continue to receive at least 10 spam messages a day - with the sender being firstname.lastname@example.org, content is usually an embeddded text & html, and the message is marked high importance. Pharmaceutial ads mostly.
Anyone have any ideas how to block this in Trend (mail coming from outside our company from ourself) or know of a virus that might cause the generation of these messages?
