Yii swiftmailer无法在实时服务器中工作

Question

Am using yii2 and i have setup a mailer as follows

  <?php
  return [
   'components' => [
  ....
    'mailer' => [
        'class' => 'yii\swiftmailer\Mailer',
        'viewPath' => '@common/mail',
        // send all mails to a file by default. You have to set
        // 'useFileTransport' to false and configure a transport
        // for the mailer to send real emails.
        'useFileTransport' => false,
        'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => 'smtp.gmail.com',
            'username' => '[e-mail]',
            'password' => 'mygmailpassword',
            'port' => '465',
            'encryption' => 'ssl',
        ],
    ],
],

];

The above works perfectly in localhost but fails when i upload to the live server i always get an error of bad credentials

The error is

Swift_TransportException

 Expected response code 250 but got code "535", with message "535-5.7.8     
Username and Password not accepted. Learn more at

Answer 1

I use this config for gmail (and work)

        'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => 'smtp.gmail.com',
            'username' => '[e-mail]',
            'password' => 'mypass',
            'port' => '587',
            'encryption' => 'tls',
        ],
