This is the error I get back from telnet
C:\Documents and Settings\Administrator>telnet mail 25
Connecting To mail...Could not open connection to the host, on port
25: Connect failed
Also to the best of my knowledge there is no firewall running.
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?
