3. 10 core/lib/Drupal/Core/Mail/MailManager.php \Drupal\Core\Mail\MailManager::doMail()

Composes and optionally sends an email message.

Parameters

string $module: A module name to invoke hook_mail() on. The {$module}_mail() hook will be called to complete the $message structure which will already contain common defaults.

string $key: A key to identify the email sent. The final message ID for email altering will be {$module}_{$key}.

string $to: The email address or addresses where the message will be sent to. The formatting of this string will be validated with the PHP email validation filter. Some examples are:

• user@example.com
• user@example.com, anotheruser@example.com
• User <user@example.com>
• User <user@example.com>, Another User <anotheruser@example.com>

string $langcode: Language code to use to compose the email.

array $params: (optional) Parameters to build the email. Use the key '_error_message' to provide translatable markup to display as a message if an error occurs, or set this to false to disable error display.

string|null $reply: Optional email address to be used to answer.

bool $send: If TRUE, call an implementation of \Drupal\Core\Mail\MailInterface->mail() to deliver the message, and store the result in $message['result']. Modules implementing hook_mail_alter() may cancel sending by setting $message['send'] to FALSE.

Return value

array The $message array structure containing all details of the message. If already sent ($send = TRUE), then the 'result' element will contain the success indicator of the email, failure being already written to the watchdog. (Success means nothing more than the message being accepted at php-level, which still doesn't guarantee it to be delivered.)
