Hi, now I have removed postfix (/etc/init.d/postfix stop), the problem still exists. Telnet exits with the error message 'Unable to connect to remote host: No route to host'.
I get this message only when I try to connect through port 25 (and that is probably the reason postfix can not send mail). Could this have something to do with firewalls? I have ip-masquerading running, but when I do a 'ipchains -F forward' (that should disable ipchains, me is told), the problem still exists. How do I solve it?
