I have been experiencing a major problem with Exchange 2003 SP1. I am not configured as a open relay, However I have numerous unwanted SMTP Connectors that continue to connect and send mass amounts of mail from my server. I take the steps to delete the queues but they return immediately. I am not sure if this is related but I am now unable to receive email on the domain dispite all attemps to resolve this issue ( I can connect to the server via telnet and I can send emails and the exchange server and network reports no virus activity) I have also disabled outbound email in an attempt to stop mail from being transmitted. Anyone have clue to what this is? I am stumped. Thanks
