Hi Akshay,
There might be three reasons
1) Your MTA must not be binded on port 25 for the interface 192.168.0.1
To resolve this check out ur MTA's Config and ask it to bind on all network interfaces.
2) you must be running RH which has a default ipchains or iptables script which by default blocks each n every incoming connection request...
To resolve this flush all rules of ipchains or iptables and disable this script frm startup using ntsysv --level=# (3 or 5)
3) Your MTA must not have started ... or must have failed to start...
To resolve this try starting it with a tail on the messages and maillog in /var/log
Hope this helps .... Best Regards, -Mitul Limbani (mitull @ wrox.com) Support Editor Wrox India http://www.wrox.com/ http://p2p.wrox.com/
