Symfony 3.1 swiftmailer email doesn't send - symfony

Question

I wanted to send a test email by using Symfony 3.1 and SwiftMailer, but it doesn't work. I was reading other solutions, but it still doesn't work.
Config.yml:
swiftmailer:
transport: %mailer_transport%
encryption: %mailer_encryption%
auth_mode: %mailer_auth_mode%
host: %mailer_host%
username: %mailer_user%
password: %mailer_password%
spool: { type: memory }
Parameters.yml
mailer_transport: smtp
mailer_encryption: ssl
mailer_auth_mode: login
mailer_host: smtp.gmail.com
mailer_user: user#gmail.com
mailer_password: mypass
Parameters.yml v.2 I was trying:
mailer_transport: gmail
mailer_encryption: ssl
mailer_auth_mode: login
mailer_host: smtp.gmail.com
mailer_user: user#gmail.com
mailer_password: mypass
Controller:
public function contactAction(Request $request)
{
$name = $request->request->get('name');
$surname = $request->request->get('surname');
$email = $request->request->get('email');
$subject = $request->request->get('subject');
$message = $request->request->get('message');
$data = "";
if($request->request->get('contact_submit')){
$message = \Swift_Message::newInstance()
->setSubject($subject)
->setFrom($email)
->setTo('myemail#gmail.com')
->setBody($message);
$this->get('mailer')->send($message);
$data = "Thank you: $name";
}
return $this->render('przedszkole/contact.html.twig', array('data' => $data));
}
So after click Submit, my view change and show me: Thank you $name, but i don't get any email :/
I change security lvl of my gmail e-mail like someone tell in other solutions, but it doesn't help for me :/
I also uncomment swiftmailer: delivery_adress in config_dev.yml.
I will be grateful for any help :/

Answer 1

How about you use (only) the following YML config:
mailer_transport: gmail
mailer_user: user#gmail.com
mailer_password: mypass
I read that there are default settings that you don't need to set for gmail and maybe because you are setting, it has some effect. I'm not sure if this will fix the problem, but you can try it.

Answer 2

I guess the problem might be with emails going into spool queue. This I had seen with someone else as well. You can explicitly disable it using:
spool:
enabled: false

Answer 3

I got a chance to debug your code and all I get is you need to change these two lines
->setFrom($email)
->setTo('myemail#gmail.com')
as
->setFrom('myemail#gmail.com')
->setTo($email)
setFrom() will contain your email ID and setTo() will have the recipients ID.
