Hello guys i am trying to send an email in magento using custom email templates. But I am getting exception I have installed SMTP Pro Extension.

I am listing code here:-

My config.xml

  <email>
    <custom_abc_email_template  module="custom_abc">
      <label>Custom Template</label>
      <file>custom_abc_templates/customTemplate.html</file>  // this specifies the path where the custom template is located
      <type>html</type>
    </custom_abc_email_template>
  </email>
</template>

code of my controller action

$emailTemplate  = Mage::getModel('core/email_template')->loadDefault('custom_abc_email_template');
$emailTemplate->setSenderName('custom template');
$emailTemplate->setSenderEmail('abc@demomail.com');
$emailTemplate->send('abc@demomail.com','Forgot Password');

My Template file code

<table cellpadding="0" cellspacing="0" border="0">
    <tr>
        <td class="action-content">
            <h1>Custom Abc,</h1>
            <p><strong>Your new password is:</strong> trolled</p>
            <p>You can change your password at any time by logging into <a href="{{store url="customer/account/"}}">your account</a>.</p>

Resolved the same exception with change to Magento system email setting. The exception is set in email template code of the plugin (see below).

In Admin select System -> Configuration from top-menu, and go to System - Mail Sending settings. Set "Disable Email Communications" to "No".

if (!$this->isValidForSend()) {
    $_helper->log('Email is not valid for sending, this is a core error that often means there\'s a problem with your email templates.');
    Mage::logException(new Exception('This letter cannot be sent.')); // translation is intentionally omitted
    return false; }
