Linux

I have a mail server that I have just finished setting up and now the problem is telneting to it from a window desktop which is on the same network. Ive edited etc/mail/sendmail.mc by removing the loopback address with my desktop IP. then I restarted my service mail:
shutting down sendmail: [ OK ]
shutting down sm-client: [FAILED]
starting sendmail: [ OK ]
starting sm-client : [ OK ]
now when I run telnet to the server 192.168.0.1 25 :
the results is that it could not connect on the host on port 25
even if I disable the firewall

Hi there,

You should ensure a sendmail daemon process is running: 'ps -ef | grep sendmail'

Then, you should check if there is a process (hopefully sendmail) listening on that port:
'lsof -itcp:25' or 'netstat -at | grep LIST' to list all listening tcp port ...

If all the check looks good, try telneting to port 25 from localhost: 'telnet 127.0.0.1 25' and if it works flush all the iptables rulez: 'iptables -F'
