CakePHP - Email Configuration
Email can be configured in file config/app.php. It is not required to define email configuration in config/app.php. Email can be used without it; just use the respective methods to set all configurations separately or load an array of configs. Configuration for Email defaults is created using config() and configTransport().
Email Configuration Transport
By defining transports separately from delivery profiles, you can easily re-use transport configuration across multiple profiles. You can specify multiple configurations for production, development and testing. Each transport needs a className. Valid options are as follows −
Mail − Send using PHP mail function
Smtp − Send using SMTP
Debug − Do not send the email, just return the result
You can add custom transports (or override existing transports) by adding the appropriate file to src/Mailer/Transport.Transports should be named YourTransport.php, where 'Your' is the name of the transport. Following is the example of Email configuration transport.
'EmailTransport' => [ 'default' => [ 'className' => 'Mail', // The following keys are used in SMTP transports 'host' => 'localhost', 'port' => 25, 'timeout' => 30, 'username' => 'user', 'password' => 'secret', 'client' => null, 'tls' => null, 'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), ], ],
Email Delivery Profiles
Delivery profiles allow you to predefine various properties about email messages from your application and give the settings a name. This saves duplication across your application and makes maintenance and development easier. Each profile accepts a number of keys. Following is an example of Email delivery profiles.
'Email' => [ 'default' => [ 'transport' => 'default', 'from' => 'you@localhost', ], ],
