I am looking at my Queues and I found two entries that seem to be a hack: SmallBusiness SMTP Connector - rezware.net (SMTP Connector) SmallBusiness SMTP Connector - webelists.com (SMTP Connector) I decided to freeze them as they seem to be hacks. Am I right? How do I prevent this from happening again? I am a bit paranoid and do not know all the ins and outs of Exchange yet. Thanks!
