Error: Transport config "Smtp" is missing in cakephp 3.x - php

Question

Transport config "Smtp" is missing in cakephp 3.x
I have tried some of the configuration which are as follows:
'EmailTransport' => [
'default' => [
'className' => 'Smtp',
'host' => 'ssl://smtp.gmail.com',
'port' => 465,
'username' => 'xxxxxxxxx#gmail.com',
'password' => 'xxxxx',
],
],
'Email' => [
'default' => [
'from' => array('site#localhost' => 'Data Mining'),
'transport' => 'Smtp',
'charset' => 'utf-8',
'headerCharset' => 'utf-8',
],
],
And i have used below code to send email.
$mail = new Email('default');
$mail->emailFormat('html');
$mail->template($template, null)->viewVars(array('body' => $mailBody));
$mail->to($email_to);
$mail->subject($subject);
$mail->replyTo(Configure::read('config.NOREPLY_EMAIL'));
$headers = array(
'X-MC-MergeVars' => '{"NAME": "Khushang", "REGARDS":"Khushang"}',
'X-MC-Template' => 'test-by-Khushang'
);
$mail->setHeaders($headers);
$mail->send();
Thank you so much...

Answer 1

You are giving transport config as Smtp in Email but you have not defined it in EmailTransport config.
Either set 'transport' => 'Smtp', to 'transport' => 'default',
OR
Set 'default' under 'EmailTransport' to 'Smtp'

Answer 2

Cakephp 3x set to app.php in config folder
'EmailTransport' => [
'default' => [
'className' => 'Mail',
// The following keys are used in SMTP transports
'host' => 'localhost',
'port' => 25,
'timeout' => 600,
'username' => 'user',
'password' => 'secret',
'client' => null,
'tls' => null,
'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null),
],
'mailjet' => [
'host' => 'smtp.xxxxxxx.com',
'port' => 465,//your ssl or none ssl port no
'username' => 'xxxxxxxxxx', //your smtp mail id
'password' => '***************', //your email password
'timeout' => 60,
'secure' => 'ssl',
'tls' => false,
'className' => 'Smtp'
]
],
Your Controller page
$email = new Email();
$email->transport('mailjet');
$email->from($from)
//->attachments(TICKET_PDF . $file)
->to($to)
->emailFormat('html')
->subject($subject)
->viewVars(array('msg' => $message))
->send($message);
