I'm curious, how exactly does mailsnarf, msgsnarf, etc work? I tried mailsnarf -i eth1 and this is all it says, "mailsnarf: listening on eth0". However nothing ever happens, I've tried sending emails to myself on my gmail account but it doesn't pickup anything. I also tried using another computer on the network to send an email to my account but it still didn't pick anything up. I have ettercap running with ARP Poisoning. Thanks.
