I've annoyed people in the CB with this for the past few days, so I might as well spread that annoyance around. Right, I'm trying to write a perl script to mass mail html email for my University's monthly Alumni bulletin. I'm stuck using only Net::SMTP (in short the way my University server is setup that's my only option). Here's what I have so far (any style pointers would be helpful also):

use Net::SMTP;
#use Mail::Bulkmail;  #Couldn't get this working on my U server
#use Mime::Lite; #Server didn't like this

my $mail_from = 'me@server.ca';<
my @mail_to = ('1@server.com','2@server.com',...);
my $subject = 'My subject eh';
my $count = 0;
my $index = 0;

my $message = q(
<b>Some html text</b>
);

#SMTP aliases to be reused to lessen the server load by not keeping ma
+ny ports open
my $smtp1 = Net::SMTP->new('my.mailserver.ca');
my $smtp2 = Net::SMTP->new('my.mailserver.ca');
my $smtp3 = Net::SMTP->new('my.mailserver.ca');
my $smtp4 = Net::SMTP->new('my.mailserver.ca');


while($index<=$#mail_to)
{

$smtp1->mail($mail_from);
$smtp1->recipient($mail_to[$index]);
$smtp1->data();
$smtp1->datasend("To: $mail_to[$index]\n");
$smtp1-> datasend ("Subject: $subject\n");
$smtp1-> datasend ("Mime-Version: 1.0\;\n");
$smtp1-> datasend ("Content-Type: text/html; charset='ISO-8859-1';\n\n
+");
$smtp1->datasend($message);
$smtp1->dataend();

$index++;

$smtp2->mail($mail_from);
$smtp2->recipient($mail_to[$index]);
$smtp2->data();
$smtp2->datasend("To: $mail_to[$index]\n");
$smtp2-> datasend ("Subject: $subject\n");
$smtp2-> datasend ("Mime-Version: 1.0\;\n");
$smtp2-> datasend ("Content-Type: text/html; charset='ISO-8859-1';\n\n
+");
$smtp2->datasend($message);
$smtp2->dataend();

$index++;

$smtp3->mail($mail_from);
$smtp3->recipient($mail_to[$index]);
$smtp3->data();
$smtp3->datasend("To: $mail_to[$index]\n");
$smtp3-> datasend ("Subject: $subject\n");
$smtp3-> datasend ("Mime-Version: 1.0\;\n");
$smtp3-> datasend ("Content-Type: text/html; charset='ISO-8859-1';\n\n
+");
$smtp3->datasend($message);
$smtp3->dataend();

$index++;

$smtp4->mail($mail_from);
$smtp4->recipient($mail_to[$index]);
$smtp4->data();
$smtp4->datasend("To: $mail_to[$index]\n");
$smtp4-> datasend ("Subject: $subject\n");
$smtp4-> datasend ("Mime-Version: 1.0\;\n");
$smtp4-> datasend ("Content-Type: text/html; charset='ISO-8859-1';\n\n
+");
$smtp4->datasend($message);
$smtp4->dataend();

$index++;

$count += 4;

if($count == 40)
{
sleep(60);
$count = 0;
}

}

$smtp1->quit;
$smtp2->quit;
$smtp3->quit;
$smtp4->quit;

print "Mail sent succesfully, I think :)";

PS: I'm not sure if this is possible but can you send an email that will display html in html compatible email readers and text otherwise? (if so how would I encorporate this into my example)
PPS: No, I don't really what I'm doing :)
