voucher email not sent?

email isn't in my spam box..

Hi,

My server settings were are ok. All other drupal mail sending happens ok.

It appears the arguments you were supplying to drupal_mail were not formatted correctly. I modified invvoucher_send_invite by modifying drupal_mail_send() (see code below) and now it works ok for me...

/**
 *   Send email with code
 */
function invvoucher_send_invite($op, $user_name = '[username]', $email = '[recipient-email]', $code = 'registration-code', $message = '[your message]', $expired='[days left]', $quantity='[possible registrations]'){

global $base_url, $user;

$default_from = variable_get('site_mail', ini_get('sendmail_from'));
$subject = variable_get('invvoucher_subject', t("You've been invited"));
$template = invvoucher_get_mail_template();
$site = variable_get('site_name', t('Drupal'));
$join_link = variable_get('invvoucher_register_URL', $base_url);
$homepage = $base_url;
$inviter = $user_name;

if ($quantity == -1){
	$quantity = t("any number of");
}

$body = t($template, array('@site' => $site, '@join_link' => $join_link, '@homepage' => $homepage, '@message' => $message, '@inviter' => $inviter, '@number' => $code, '@expired' => date("Y-m-d",$expired), '@quantity'=> $quantity));

// Bundle up the variables into a structured array for altering.
$message = array(
  'id'       => 'invite-email',
  'to'       => $email,
  'from'     => isset($from) ? $from : $default_from,
  'language' => $language,
  'params'   => $params,
  'subject'  => $subject,
  'body'     => $body
);

// Build the default headers
$headers = array(
  'MIME-Version'              => '1.0',
  'Content-Type'              => 'text/plain; charset=UTF-8; format=flowed; delsp=yes',
  'Content-Transfer-Encoding' => '8Bit',
  'X-Mailer'                  => 'Drupal'
);

if ($default_from) {
  // To prevent e-mail from looking like spam, the addresses in the Sender and
  // Return-Path headers should have a domain authorized to use the originating
  // SMTP server. Errors-To is redundant, but shouldn't hurt.
  $headers['From'] = $headers['Reply-To'] = $headers['Sender'] = $headers['Return-Path'] = $headers['Errors-To'] = $default_from;
}

if ($from) {
  $headers['From'] = $headers['Reply-To'] = $from;
}

$message['headers'] = $headers;

// Concatenate and wrap the e-mail body.
//$message['body'] = is_array($message['body']) ? drupal_wrap_mail(implode("\n\n", $message['body'])) : drupal_wrap_mail($message['body']);

// Optionally send e-mail.
  $message['result'] = drupal_mail_send($message);

  // Log errors
  if (!$message['result']) {
    watchdog('mail', 'Error sending e-mail (from %from to %to).', array('%from' => $message['from'], '%to' => $message['to']), WATCHDOG_ERROR);
    drupal_set_message(t('Unable to send e-mail. Please contact the site admin, if the problem persists.'), 'error');
  }

return $message['result'];
}
