I have an Exchange 2000 server that is running Trend-Micro ScanMail. I have tested the server for open relay and have had no probelms with it for the last year. The last couple days ScanMail has blocked 12 different messages containing one of the many popular viruses. Normally this would not alarm me, however the sender of some of the messages "appear" to be sent from an internal account that doesn't exist, staff@companyname.com. There is no user or delivery mailbox setup for staff.
Has someone in the organization been infected or has someone from outside been able to relay off my server? Thanks in advance.
