Configuration

Mail - Sendmail

If your server has Sendmail installed, update the config/autoload/mail.local.php.dist file by setting the transport key like below

<?php
return [
    'dot_mail' => [
        'default' => [
            //...
            'transport' => Laminas\Mail\Transport\Sendmail::class,
            //...
        ]
    ]
]

Mail - SMTP

If you want your application to send mails on e.g. registration, contact, then edit the file config/autoload/mail.local.php. Set the transport, message_options and smtp_options keys like below.

Under message_options key:

• from - email address from whom users will receive emails

Under smtp_options key:

• host - the mail server's hostname or IP address
• port - the mail server's port
• connection_config - fill in the username, password and ssl keys with the login details of the email used in from above

Note: all other keys can be left as is.

<?php
return [
    'dot_mail' => [
        'default' => [
            //...
            'transport' => Laminas\Mail\Transport\Smtp::class,
            'message_options' => [
                'from' => '',
                //...
            ],
            'smtp_options' => [
                'host' => '',
                'port' => 25,
                'connection_config' => [
                    'username' => '',
                    'password' => '',
                    'ssl' => '',
                ]
            ]
            //...
        ]
    ]
]

In config/autoload/local.php add under contact => message_receivers => to key string values with the emails that should receive contact messages

Note: Please add at least 1 email address in order for contact message to reach someone

Also feel free to add as many cc as you want under contact => message_receivers => cc key

Sending an e-mail

Below is an example of how to use the email in the most basic way. You can add your own code to it e.g. to get the user data from a User object or from a config file, to use a template for the body.

Note that addTo is only one of the methods available for the Message class returned by getMessage(). Other useful methods that were not included in the example are addCc(), addBcc(), addReplyTo().

The returned type is boolean, but if the isValid() method is removed, the returned type becomes MailResult which allows the use of getMessage() for a more detailed error message. See the Testing if an e-mail message is valid section below.

public function sendBasicMail()
{
    $this->mailService->setBody('Email body');
    $this->mailService->setSubject('Email subject');
    $this->mailService->getMessage()->addTo('email@example.com', 'User name');
    $this->mailService->getMessage()->setEncoding('utf-8');
    return $this->mailService->send()->isValid();
}

It's optional, but recommended to call the above function in a try-catch block to display helpful error messages. The next example calls the sendBasicMail function from within UserController, but you can implement it in other controllers, just make sure that the controller's construct also includes the FlashMessenger parameter $messenger.

try {
    $this->userService->sendBasicMail();
    $this->messenger->addSuccess('The mail was sent successfully', 'user-login');
    //more code...
} catch (Exception $exception) {
    $this->messenger->addError($exception->getMessage(), 'user-login');
    //more code...
}

Testing if an e-mail message is valid

After sending an e-mail you can check if the message was valid or not. The $this->mailService->send()->isValid() method call will return a boolean value. If the returned result is true, the e-mail was valid, otherwise the e-mail was invalid. In case your e-mail was invalid, you can check for any errors using $this->mailService->send()->getMessage().

Using the below logic will let you determine if a message was valid or not and log it. You can implement your own custom error logging logic.

$result = $this->mailService->send();
if (! $result->isValid()) {
    //log the error
    error_log($result->getMessage());
}

Note : Invalid e-mail messages will not be sent.

Logging outgoing emails

Optionally, you can keep a log of each successfully sent email. This might be useful when you need to know if/when a specific email has been sent out to a recipient.

Logs are stored in the following format: [YYYY-MM-DD HH:MM:SS]: {"subject":"Test subject","to":["Test Account <test@dotkernel.com>"],"cc":[],"bcc":[]}.

In order to enable it, make sure that your config/autoload/mail.local.php has the below log configuration under the dot_mail key:

<?php

return [
    'dot_mail' => [
        ...
        'log' => [
            'sent' => getcwd() . '/log/mail/sent.log'
        ]
    ]
];

To disable it, set the value of sent to null.

Saving a copy of an outgoing mail into a folder

Valid only for SMTP Transport

First, make sure the save_sent_message_folder key is present in config file mail.local.php under dot_mail.default. Below you can see its placement and default value.

<?php

return [
    'dot_mail' => [
        'default' => [
        ...
            'save_sent_message_folder' => ['INBOX.Sent']
        ],
    ],
];

Common folder names are INBOX, INBOX.Archive, INBOX.Drafts, INBOX.Sent, INBOX.Spam, INBOX.Trash. If you have MailService available in your class, you can call $this->mailService->getFolderGlobalNames() to list the folder global names for the email you are using.

Multiple folders can be added to the save_sent_message_folder key to save a copy of the outgoing email in each folder.
