I recently wrote a program that needs to send messages through SMTP every few minutes. Since I'm running this behind an Earthlink DSL modem, I can only connect on port 25 if I'm connecting to the Earthlink STMPAUTH server. (Damn them and their restrictions!).

Anyway, I wrote a script that sends the mail and it works perfectly. The problem is that if the message gets sent twice from the same script, I get an error and the mail doesn't go through. I figured it might have been the rest of my code, so I isolated the mailing sub and tried again. No dice. Why would this happen?

Here's my code: 

#!/usr/bin/perl

use Net::SMTP;

use strict;
use warnings;

for(1..2)
{

my $smtp = Net::SMTP->new('smtpauth.earthlink.net', 
                          Hello => 'milkbone.org', Debug => 1) or die 
+"death";

$smtp->auth('batkins86@earthlink.net', '***************************');
$smtp->mail('monitor@milkbone.org');
$smtp->to('test@batkins.com');

$smtp->data();
$smtp->datasend("To: postmaster\n");
$smtp->datasend("\n");
$smtp->datasend("A simple test message\n");
$smtp->dataend();

$smtp->quit;

}

Of course, the password is blanked out. The first time this goes through perfectly. But the second time, the tail end of the Debug output reads:

I'm stumped. Any ideas?
