symfony2: emails are not sent - php

Question

$mail = \Swift_Message::newInstance()
->setSubject($message->getSubject())
->setFrom($message->getEmail())
->setBody($message->getBody());
$this->get('mailer')->send($mail);
Mails are not sent when using swiftmailer. Yet, when I go step by step in the debugger, it seems to send the email and returns sent=1. However I don't receive anything in my mailbox (gmail). I use my gmail account for sending emails, as shown below:
parameters:
mailer_transport: gmail
mailer_host: ~
mailer_user: username#gmail.com
mailer_password: my-password
delivery_address: username#gmail.com
swiftmailer:
transport: %mailer_transport%
host: %mailer_host%
username: %mailer_user%
password: %mailer_password%
spool: { type: memory }
I've checked apache error log, nothing. I've run php app/console swiftmailer:spool:send just in case, but no luck.
What could prevent emails from being sent ?

Answer 1

You need either to:
1) Remove the spool line in your swiftmailer configuration, this one:
spool: { type: memory }
2) Trigger the spool queue to be sent:
php app/console swiftmailer:spool:send
But I think you are looking for option 1)

Answer 2

u can try this one...
Parameter.yml
mailer_transport: gmail
mailer_encryption: ssl
mailer_auth_mode: login
mailer_host: smtp.gmail.com
mailer_user: 'xxxxxxxxxxxx'
config.yml
swiftmailer:
transport: gmail
host: smtp.gmail.com
username: 'Yourmail-id#gmail.com'
password: 'Password'

Answer 3

The ->setTo part was missing ! That solved it.
$mail = \Swift_Message::newInstance()
->setSubject($message->getSubject())
->setFrom($message->getEmail())
->setTo("me#gmail.com")
->setBody($message->getBody());

First, when you set spool: { type: memory } it means that you actually want to send the emails manually by running the spool command: php app/console swiftmailer:spool:send. So removing that spool line is going to help.
Second, you need to properly configure your mailing host. For development purposes, I strongly recommend that you use a service such as SendGrid and configure it as detailed in this Symfony2 Mailing Setup Tutorial
The tutorial also contains details on how to properly setup a mailing service in Symfony2 and how to build mailing templates.
Third, if you want to stick with Gmail, then the correct data is:
mailer_transport: smtp
mailer_host: smtp.gmail.com
mailer_user: your_gmail_address#gmail.com
mailer_password: 'your_gmail_password'
mailer_port: 587
