Attacking Common Services - Easy - smtp-user-enum does not find any users

[PlsGiveMeFood]

I have run smtp-user-enum against the target, using mode RCPT and the user list from the ressources section. I have also specified the domain “inlanefreight.htb”. The exact command which I have used is:

smtp-user-enum -M RCPT -U users.list -D inlanefreight.htb -t 10.129.47.123

However it does not find any users:

Hi,

I had this problem, I could nmap the target but not ping it, it was weird…
Also the user scan wa failing. Fixed it by reseting my HTB vpn with a new .ovpn file.
Good luck
