Afternoon all, My firm has been hit with someone gaining access to our IP address. Using Exchange 2k. I have rechecked how it is setup, and according to what I can tell, it is setup to not allow realy. However, it is not stopping this from occuring, and clogging up the mailroot, vsi 1, queue folder. Actions taken, via exchange smc, smtp virtual server, disabled queues. Currently looking into 2 software products, NETIQ Marshall SMTP, and GFI. Does anyone have any experience with either one?
