Why My Function Not Sending Custom Email?

Question

This is the function that carries out send mail functionality. I am one hundred percent sure that, this method is calling correctly.

public function sendMail($data)
{
    try {
        // Gets the current store's id
        $storeId = Mage::app()->getStore()->getStoreId();

        $templateId = $data['mail_template'];

        $mailer = Mage::getModel('core/email_template_mailer');
        $emailInfo = Mage::getModel('core/email_info');

        //set receipient address
        $emailInfo->addTo(trim($data['mail_to']));

        $mailer->addEmailInfo($emailInfo);

        // Set all required params and send emails
        $mailer->setSender(trim($data['mail_from']));
        $mailer->setStoreId($storeId);
        $mailer->setTemplateId($templateId);
        $mailer->setTemplateParams(array(
            'subject' => trim($data['mail_sub']),
            'content' => trim($data['mail_content'])
        ));
       if ($mailer->send()) {
            Mage::getSingleton('core/session')->addSuccess('Successfully Email Sent');
            return true;
        }
    } catch (Exception $e) {
        Mage::throwException($e);
        return false;
    }

    return true;
}

Please note I didn't get any exception while doing this. Also there is no log errors. When I prints $mailer variable (holds the instance of Mage_Core_Model_Email_Template_Mailer) just above send method, I am getting this as output.

Mage_Core_Model_Email_Template_Mailer Object

                    (
                    )

            )

    )

        [sender] => sender@gmail.com
        [store_id] => 0
        [template_id] => send_mail_mailer_mail_template
        [template_params] => Array
            (

Here you can see that, every value is setting correctly here (AFAIK). But I cant see any mails received at the email address to@gmail.com.

What I have done wrong here ? At least give me some hints in order tackle the real problem. Thanks

Edit 1

I narrowed down my problem and ended up here Mage_Core_Model_Email_Template::isValidForSend(). This method returns false in my case. When I dig more there., I found out that, the line

 $this->getTemplateSubject()

is responsible for the false value. In my initial investigation, this returns fasle only if I dont have a subject set with my mail template. But I have subject included in my template like this.

 <!--@subject {{var subject}} @-->

and I can see this value when print the instance of Mage_Core_Model_Email_Template in its _data array as like this.

[_data:protected] => Array
    (
        [sent_success] => 
        [template_type] => 2
        [template_subject] => {{var subject}}
        [orig_template_variables] => {"store url=\"\"":"Store Url","var logo_url":"Email Logo Image Url","var logo_alt":"Email Logo Image Alt","var content":"Email Content"}
        [template_styles] => body,td { color:#2f2f2f; font:11px/1.35em Verdana, Arial, Helvetica, sans-serif; }
        [template_text] => 

Please note the template_subject. Dont know how to go further. If you have any thoughts please share

To Send A Mail Then you have to follow the Steps.

Step 1: Create Basic Module and register their Module.

Step 2: Then You have to create a config.xml and in that you have to register your mail template using below code.custom_template this is unique name. this is use to call this mail template.

<global>
  <template>
    <email>
        <custom_template  module="gameupload">
            <label>Send mail After Game upload</label>
            <file>gameupload/custom_template.html</file>
            <type>html</type>
        </custom_template>
    </email>
  </template>
</global>

Step 3: now you have to create mail template in app\locale\en_US\template\email\gameupload\custom_template.html

Type the Below code. where cmp_name will passed when you call the template.

<h1>Game Upload By {{var cmp_name}}</h1>

Step 4: Now open your Controller and sendMail($data)

try {
    // Gets the current store's id
    $storeId = Mage::app()->getStore()->getStoreId();
    /* Code to lode custom email template */

    $emailTemplate = Mage::getModel('core/email_template')->loadDefault('custom_template');

    //Create an array of variables to assign to template
    $emailTemplateVariables = array();
     $processedTemplate = $emailTemplate->getProcessedTemplate($emailTemplateVariables);
        $to_email = 'upload@indiemaniagames.com';
        $to_name = 'Hello IndieMania';
        $subject = 'Game Upload By ' . $data['cmp_name'];
        $Body = $processedTemplate;

        $sender_email = $data['email'];
        $sender_name = $data['cmp_name'];
         $mail = new Zend_Mail(); //class for mail
        $mail->setBodyHtml($Body); //for sending message containing html code
        $mail->setFrom($sender_email, $sender_name);
        $mail->addTo($to_email, $to_name);
        //$mail->addCc($cc, $ccname);    //can set cc
        //$mail->addBCc($bcc, $bccname);    //can set bcc
        $mail->setSubject($subject);
        try {
            if ($mail->send()) {
                Mage::getSingleton('core/session')->addSuccess('Successfully Email Sent');
            }
        } catch (Exception $ex) {
            Mage::getSingleton('core/session')->addSuccess('Email cannot sent');
        }
}

This way you can send custom mail as well as passes data form controller to mail Template.

Answer 2

My real problem was not the code that I have used to send mail. I dont have sendmail enabled in my system and it drops me down actully.

So make sure you have SMTP configurations are configured correctly. If sendmail is not in your system, then install it.

 sudo yum install sendmail  -- in fedora
 sudo apt-get sendmail      -- ubuntu

If it is installed, just restart it

sudo service sendmail restart
sudo service apache2 restart
