Hi Monks, I'm testing 1-to-1, many-to-one and many-to-many scenarios in SendMail. Meaning, using SendMail modules I need to send mails in this manner using SMTP.


1. One person simultaneously send mail to many ppl - I can use multiple recipient - So I can do this

2. Many to one - I dont know how to many multiple From (around 100000) addresses sending mail to one single To using Fork function.

3. Many to Many - meaning many ppl (say 5000 From) sending mails simultaneously To 5000 ppl using sendmail and fork.

I found Fork, but exactly not sure how to use it. Attached find my code so far i have written. Pls suggest someother better alternative to Fork if any .. The SendMail function works fine. 
#!/usr/bin/perl

use SendMail;


# get the commandline args - FromUserNo, ToUserNo from command
my $fromUserNo = $ARGV[0];
my $toUserNo = $ARGV[1];



#setup To and From lists

#Build recipient address based on ToUser 
my $myToUser = "TestTo";
my @ToUser;
for( my $i = 1; $i <= $toUserNo; $i++){
    $myToUser = "$myToUser"."$i\@xx.yy.com".";";
    $myToUser = "TestTo";    
}
push(@ToUser,$myToUser);


#Build Sender address based on FromUser 
my $myFromUser = "TestFrom";
my @FromUser;
for( my $i = 1; $i <= $fromUserNo; $i++){
    $myFromUser = "$myFromUser"."$i\@abc.com".";";
    $myFromUser = "TestFrom";    
}
push(@FromUser,$myFromUser);




#rules mail server
my $server = "xx.yy.com";    
$sm = new SendMail($server);


#One person sending to multiple receipient at once
#for (1..10){
    my $pid = fork();
    if (not defined $pid) {
        print "resources avilable, \n";
    } 
    elsif ($pid == 0) {    

        $sm->From("test1 <test1\@abc.com>");
        $sm->Subject("test");
        $sm->To("Rules <rules\@xx.yy.com>");
        $sm->setMailBody("test data");
        my $attachfile = "C:\\attachmentfile.txt";
        $sm->Attach($attachfile);

        # Check if the mail sent successfully or not.
        if ($sm->sendMail() != 0) {
            print $sm->{'error'}."\n";
            exit -1;
        }

        # Mail sent successfully.
        print "Mail sent\n\n";    

        # End child
        exit(0);
    } 

    else {
        print "IM THE PARENT\n";
        waitpid($pid,0);
    }
