this is a script i have that sends an email to a list of people. what i need to know is the easiest and best way to grep the users IP address and insert it into the headers of the outgoing email. thanks for any help. 

#!/usr/local/bin/perl
use CGI;
$foo = new CGI;
$recips = $foo->param('recipient');
$realname = $foo->param('realname');
$realemail = $foo->param('realemail');
$mailprog = '/usr/sbin/sendmail';

@recipients = split("\, ", $recips);

if(defined ($val = $foo->cookie(-name => "sent-mail"))) {
print $foo->header();
print "
<body bgcolor=\"#FFCC00\">
<p align=\"center\"><big><big><strong><font face=\"Arial\">Sorry $real
+name, emails can only be sent once.</font></strong></big></big></p>
</body>";
} else {
foreach $person (@recipients) {
($pname, $pemail) = split("\<", $person);
$pemail =~ s/\>.*//;
$pname =~ s/\s+//;
open(MAIL,"|$mailprog -t");

print MAIL "To: $pemail\n";
print MAIL "From: $realemail ($realname)\n";
print MAIL "Subject: $pname, interesting site\n\n";

print MAIL "
$pname

message.......

$realname";

close (MAIL);
}

open(FILE, ">> addresses.txt");
@addresses = <FILE>;
foreach $person (@recipients) {
($pname, $pemail) = split("\<", $person);
$pemail =~ s/\>//;
if($pemail !=~ /\s+\,\s+/) {
print FILE "$pemail\n";
}}
close(FILE);

print $foo->header();
$cookie = $foo->cookie('-name' => "sent-mail", '-value' => "sent");
print "
<body bgcolor=\"#FFCC00\">
<script language=javascript>
alert(\"Thank you\");
</script>
</body>";
}
