Use Net SMTP To Send Email

The following Perl code is an example of how you can send emails from a CGI script through your SMTP mail server.
(Remember to escape special characters you set in the mail hash)

#!/usr/bin/perl

require 5.001;
$|=0;

use Net::SMTP;
use strict;

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

# initalize hash & set SMTP parameters
my %mail = (
  'smtp_host',     "smtp.yourdomain.com",
  'smtp_port',     "25",
  'smtp_username', "xxxUSERNAMExxx",
  'smtp_password', "xxxPASSEWORDxxx",
);

# append to hash the data for the email
$mail{'from'} = "you\@yourdomain.com";
$mail{'to'}   = "somebody\@someplace.com";
$mail{'cc'}   = ""; # leave blank, when not being used.
$mail{'bcc'}  = ""; # leave blank, when not being used.
$mail{'subject'} = "Insert email subject here...";
$mail{'message'} = "Insert email message body here...";

# pass the hash to the function, to send the email
my ($status, $response) = &send_email(%mail);

# show message whether email was sent or not.
if ($status eq "success") {
  print "OK: Email was sent.\n";
}
else {
  print "ERROR: Email could not be sent. ($response)\n";
}

exit;


##### YOU SHOULD NOT NEED TO CHANGE ANYTHING BELOW THIS LINE #####

sub send_email {
  my %mail = @_;

  my ($status, $response);

  ## uncomment the below line, if you have not defined the Net::SMTP module at the top of your script.
  #use Net::SMTP;

  ## initialize Net::SMTP module; passing it the SMTP host name & port #.
  my $smtp = Net::SMTP->new("$mail{'smtp_host'}", Port=> $mail{'smtp_port'}, Debug=>0);

  ## see if SMTP connection failed.
  if ( ! $smtp ) {
    $status = "problem";
    $response = "Connection to SMTP server failed";
    warn("$status - $response");
    return("$status", "$response");
  }

  ## if connection was successful, send login info.

  ## do SASL authentication (plain text password)
  my $ret = $smtp->auth("$mail{'smtp_username'}","$mail{'smtp_password'}");

  if ( ! $ret ) {
    $status = "problem";
    $response = "SMTP authentication failed\n";
    warn("$status - $response");
    return("$status", "$response");
  }

  ## assume SMTP authentication succeeded...
  #print "SMTP authentication succeeded...\n";
 
  ## set the envelope from address
  $smtp->mail("$mail{'from'}");

  ## set the envelope recipient address
  # NOTE: this part can be called multiple times, if multiple people are to the emailed; or simply set all emails in an array & pass the array in)
  $smtp->recipient("$mail{'to'}");

  ## now try to send the email:

  ## initialize email message
  $smtp->data();

  ## insert email data (To, From, Subject)
  $smtp->datasend("From: $mail{'from'}\n");
  $smtp->datasend("To: $mail{'to'}\n");
  if ($mail{'cc'} ne "") {
    $smtp->datasend("Cc: $mail{'cc'}\n");
  }
  if ($mail{'cc'} ne "") {
    $smtp->datasend("Bcc: $mail{'bcc'}\n");
  }
  $smtp->datasend("Subject: $mail{'subject'}\n");
  $smtp->datasend("\n"); # mandatory before starting the email message body

  ## insert email message body
  $smtp->datasend("$mail{'message'}");

  ## indicate end of the email message
  $smtp->dataend();

  ## close the SMTP connection
  $smtp->quit();

  ## now return a response to the calling script/function.
  $status = "success";
  $response = "Email Sent";
  return("$status", "$response");
}
