  12. * Mailer implements a mailer based on SwiftMailer.
  13. *
  14. * To use Mailer, you should configure it in the application configuration like the following,
  15. *
  16. * ~~~
  17. * 'components' => [
  18. * ...
  19. * 'mailer' => [
  20. * 'class' => 'yii\swiftmailer\Mailer',
  21. * 'transport' => [
  22. * 'class' => 'Swift_SmtpTransport',
  23. * 'host' => 'localhost',
  24. * 'username' => 'username',
  25. * 'password' => 'password',
  26. * 'port' => '587',
  27. * 'encryption' => 'tls',
  28. * ],
  29. * ],
  30. * ...
  31. * ],
  32. * ~~~
  33. *
  34. * You may also skip the configuration of the [[transport]] property. In that case, the default
  35. * PHP `mail()` function will be used to send emails.
  36. *
  37. * You specify the transport constructor arguments using 'constructArgs' key in the config.
  38. * You can also specify the list of plugins, which should be registered to the transport using
  39. * 'plugins' key. For example:
  40. *
  41. * ~~~
  42. * 'transport' => [
  43. * 'class' => 'Swift_SmtpTransport',
  44. * 'constructArgs' => ['localhost', 25]
  45. * 'plugins' => [
  46. * [
  47. * 'class' => 'Swift_Plugins_ThrottlerPlugin',
  48. * 'constructArgs' => [20],
  49. * ],
  50. * ],
  51. * ],
  52. * ~~~
  53. *
  54. * To send an email, you may use the following code:
  55. *
  56. * ~~~
  57. * Yii::$app->mailer->compose('contact/html', ['contactForm' => $form])
  58. * ->setFrom('from@domain.com')
  59. * ->setTo($form->email)
  60. * ->setSubject($form->subject)
  61. * ->send();
  62. * ~~~
  63. *
  64. * @see http://swiftmailer.org
  65. *
  66. * @property array|\Swift_Mailer $swiftMailer Swift mailer instance or array configuration. This property is
  67. * read-only.
  68. * @property array|\Swift_Transport $transport This property is read-only.
