gilesy has asked for the wisdom of the Perl Monks concerning the following question:

Hi guys, I'm attempting to use the Net::SMTP module in order to send emails from a server that i'm remotely logging into. Please see the basic code I've set up below. I am attempting to get this working first before fleshing out the actual script. 
#!/usr/bin/perl

use Net::SMTP;
use strict;
use warnings;

print "Content-type: text/html\n\n";
#print "test";

my $MailHost = "smtp.server.com";
my $MailFrom = "from\@address.com";
my $MailTo = "gilesy\@address.com";
my $subject = "Hello Gilesy";
my $MailBody = "This is the mail body";

#confirm connection with smtp server

my $smtp_test = Net::SMTP->new('smtp.server.com',
Timeout => 30,
Debug => 1,)|| print "ERROR creating SMTP obj: $! \n";
print "SMTP obj created.";

my $smtp = Net::SMTP->new($MailHost);
# Send the From and Recipient for the mail servers that require it

$smtp->mail($MailHost);
$smtp->to($MailTo);
# Start the mail
$smtp->data();
# Send the header.
$smtp->datasend("To: $MailTo\n");
$smtp->datasend("From: $MailFrom\n");
$smtp->datasend("Subject: $subject\n");
$smtp->datasend("\n");

# Send the message
$smtp->datasend("$MailBody\n\n");

# Send the termination string
$smtp->dataend();
$smtp->quit;

When I run this, I get the following output:

From what I can see, there are no errors here. However, when I run this, I do not get any emails. This could be to do with server security but I guess I want to rule out that my code is the issue. So could anyone confirm if my code is ok? If so, would you have any suggestions as to what might be causing the issue?

      my $MailFrom = "from\@address.com";
my $MailTo = "gilesy\@address.com";

        Update:

        Sorry, the first line was wrong for you. But i think you noted this.

        #!/usr/bin/perl

use Net::SMTP;
use strict;
use warnings;

print "Content-type: text/html\n\n";

my $MailHost = "mailhost";
my $MailFrom = "someone\@somewhere";
my $MailTo   = "someone\@somewhere";
my $subject  = "Super!\n";
my $MailBody = "It works!\n";
my $smtp     = Net::SMTP->new($MailHost) || die $!;

$smtp->mail($MailFrom);
$smtp->to($MailTo);

$smtp->data();

$smtp->datasend("To: $MailTo\n");
$smtp->datasend("From: $MailFrom\n");
$smtp->datasend("Subject: $subject\n");
$smtp->datasend("\n");
$smtp->datasend("$MailBody\n\n");

$smtp->dataend();
$smtp->quit;
