yii2 mailer smtp connection refused - email

Question

When setting up my smtp mailer in the config file, it works fine. But if I manually create the SMPT mailer it fails (Connection refused). Can anybody assist?
Yii2 config file:
'components'=[
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.gmail.com',
'username' => 'email#gmail.com',
'password' => 'password',
'port' => '587',
'encryption' => 'tls',
],
The following code in my controller does not work:
$mailer = new \yii\swiftmailer\Mailer();
$mailer->transport = new \Swift_SmtpTransport();
$mailer->transport
->setHost('smtp.gmail.com')
->setPort(587)
->setEncryption('tls');
$mailer->transport->setUsername('email#gmail.com');
$mailer->transport->setPassword('password');
and I receive an error message: Connection refused #111
I have tried port 465 on ssl and I receive the same message.
My main reason for doing this is that I have different client accounts, each of which has its own smtp. I therefore need one account per client and I cannot seem to do that via the config file.
Many thanks for your help.

I just tried it worked for me, I did as follow
'components'=[
'mailer' => [ //Your default mailer
'class' => 'yii\swiftmailer\Mailer',
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.gmail.com',
'username' => 'email#gmail.com',
'password' => 'password',
'port' => '587',
'encryption' => 'tls',
],
],
'mailer2' => [ //Your custom mailer
'class' => 'yii\swiftmailer\Mailer',
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.gmail.com',
'username' => 'new_email#gmail.com',
'password' => 'new_password',
'port' => 'new_port587',
'encryption' => 'new_tls',
],
]
following is for default config
Yii::$app->mailer->compose()
->setFrom('info#gmail.com')
->setTo('xxx#gmail.com')
->setSubject('Subject')
->setTextBody('Plain text content')
->setHtmlBody("Hello")
->send();
following with custom mailer config
Yii::$app->mailer2->compose()
->setFrom('info#gmail.com')
->setTo('xxx#gmail.com')
->setSubject('Subject')
->setTextBody('Plain text content')
->setHtmlBody("Hello")
->send();
create a component is the fastest solution, otherwise, you can use the parameter to store configuration, and call when needed.
