Cakephp3 sending mails - no result - php

Question

I'm trying to send email via cakephp3.
This is my app email config:
'EmailTransport' => [
'default' => [
'className' => 'Mail',
// The following keys are used in SMTP transports
'host' => 'localhost',
'port' => 25,
'timeout' => 30,
'username' => 'user',
'password' => 'secret',
'client' => null,
'tls' => null,
],
],
And this is controller :
public function index() {
$this->autoRender = false;
$email = new Email('default');
if (
$email->from(['mymail#gmail.com' => 'My Site'])
->to('mymail#gmail.com')
->subject('About')
->send('My message')) {
print 'ok';
}
}
And now, if i run this function, result is printed 'ok' on monitor.
But no mail is on my testing email box, even span, nothing.
My question is, why cakephp tells me that sending was done, but no mail is present on my box ?
Thank You.

Answer 1

Your configuration is incorrect. cakePHP attempts to send the e-mail via smtp to your localhost.
Most likely you do not have an MTA (ie. exim, dovecot) installed locally and the request gets dropped. This should be visible as an error in you logs (if enabled).
An easy solution is to change the configuration to a working email service for testing, for example Gmail.
Example:
Email::configTransport('gmail', [
'host' => 'smtp.gmail.com',
'port' => 587,
'username' => 'my#gmail.com',
'password' => 'secret',
'className' => 'Smtp',
'tls' => true
]);
Note that the host and port point to Gmail. This example is indicative and was taken from the official documentation.
