When I start a scan on my mail server it requests, queries, runs for a few secs and stops and says done with almost no scans. I don’t know whats wrong or why is strait out refuses to scan it. I do have fail 2 ban but I allowed the IP I was scanning from.
Just to see what type of install you’re running (since you mentioned a VM), is the VM a Kali VM running within another operating system, or a virtual appliance running inside Kali? Can you post a link to which version you downloaded? Thanks!
