I think a better option would be a script that tails the message log and emails you when it finds and instance of the keyword??
better still there are apps that can do this for you. once called swatch and logging software called syslog-ng - which replaces the normal syslog software

It's not necessary to confige a sendmail to send mail to company email server.There are some script which can send mail by SMTP server.I can give you some example about send mail script .but you need to writing the script to "check for particular keyword in /var/log/message file"

Code:

#!/usr/bin/perl -w
use Net::SMTP_auth;
use Time::Local;
use Sys::Hostname;

$username='abc';
$password='abc';
$smtp = Net::SMTP->new('domainname',Hello =>'domainname');
$smtp->auth($username,$password);
$smtp->mail('abc@domainname');
$smtp->to('abc@gmail.com');
$smtp->data();
$smtp->datasend("hello world ! \n");
$smtp->quit;

The Perl module for tailing a file is http://search.cpan.org/~mgrabnar/Fil...0.99.3/Tail.pm

Code:

nmap localhost
PORT     STATE SERVICE
21/tcp   open  ftp
22/tcp   open  ssh
25/tcp   open  smtp

Pls help me....

I telnet the vinay.linux.com 25 port it's not open .maybe the mailserver is your private mailserver.anyway ,you need to test the vinay.linux.com domain can send mail.you may be send a mail by the normal client ,like outlook. to test the vinay.linux.com is fine.
and maybe the

Code:

$smtp = Net::SMTP->new('linux.com',Hello =>'linux.com');

linux.com can replace by vinay.linux.com to try again.

Are you trying to recv mail on localhost or your eth0 IP?
By default at install, sendmail only listens on localhost (127.0.0.1).
