The only linux machine on the network is a thinclient so I do not think that will work? As it will think it is the "mail" server.
I tried from my schools server and cannot telnet in either? but could that be because of the mynetworks line? and not having there range of ips in it? tcp 0 0 *:smtp *:* LISTEN tcp 0 0 localhost:2207 *:* LISTEN I found this using netstat so I figure it is running? iptables is empty. > I also have this in my main.cf > mynetworks = 127.0.0.0./8 192.168.0.0/24 192.168.1.0/24 So any client > that is on my network should be able to connect, no? > > [ NB: 127.0.0.0./8 has one too many dots ] > >I would have thought so, yes.

Nope I cannot telnet the gmail mail host that was said earlier. >3. You can connect by name to port 25 from your mail server, but you get > "relaying denied".
