In my dev enviroment I want to use mailhog to catch the emails. I've installed and configure my php.ini to sustitute the sendmail property.
If in command line i run this

php -r "mail(......);" 

the mail gets captured by mailhog. The problem is with Symfony and Swiftmailer. To make a test i created a very simple controller with this:

/**

     * @return Response

     */

    public function homeAction() : Response

    {

        mail('some@mail.com', 'tasest', 'aaaa');

        $message = Swift_Message::newInstance()

            ->setSubject('Hello Email')

            ->setFrom('send@example.com')

            ->setTo('recipient@example.com')

            ->setBody(

                'aaaaa',

                'text/html'

            );

        $this->get('mailer')->send($message);

        return $this->render('::base.html.twig');

    }

Now, the email sent by the mail function gets captured by mailhog. But not the mail sent by SwiftMailer.

In my config_dev I have this:

    # Swiftmailer Configuration

swiftmailer:

    transport: "sendmail"

which I think should be enough.

Am I missing something here?

P.S.: If i use a real address (instead of recipient@example.com) the email gets sent and received

Update:
I also tried to configure mailhog for smtp, parameters.yml:

mailer_transport: smtp

mailer_host: 127.0.0.1

mailer_port: 1025

mailer_user: null

mailer_password: null

config.yml:

swiftmailer:

    transport: "%mailer_transport%"

    host:      "%mailer_host%"

    port:      "%mailer_port%"

    username:  "%mailer_user%"

    password:  "%mailer_password%"

    spool:     { type: memory }

But the result was the same result.

Swiftmailer setup in Symfony will usually have a more complete configuration, particularly in config_dev.yml, to be explicit of where you would send it.

swiftmailer:

    transport: "%mailer_transport%"

    host:      "%mailer_host%"

    port:      "%mailer_port%"

    username:  "%mailer_user%"

    password:  "%mailer_password%"

Here, if Mailhog was on port 1025 (very typical), then parameters.yml in a development environment would be set like this, to fill in the parameters in the .yml file:

mailer_transport: smtp

mailer_host: 127.0.0.1

mailer_port: 1025

mailer_user: null

mailer_password: null

I have the same problem with Symfony 4.
If you delete the variable url: '%env(MAILER_URL)%' in config/packages/swiftmailer.yaml, it should work.
