hook_mail($key, &$message, $params)
Prepares a message based on parameters;
This hook is called from MailManagerInterface->mail(). Note that hook_mail(), unlike hook_mail_alter(), is only called on the $module argument to MailManagerInterface->mail(), not all modules.
Parameters
$key: An identifier of the mail.
$message: An array to be filled in. Elements in this array include:
- id: An ID to identify the mail sent. Look at module source code or MailManagerInterface->mail() for possible id values.
- to: The address or addresses the message will be sent to. The formatting of this string must comply with RFC 2822.
- subject: Subject of the email to be sent. This must not contain any newline characters, or the mail may not be sent properly. MailManagerInterface->mail() sets this to an empty string when the hook is invoked.
- body: An array of lines containing the message to be sent. Drupal will format the correct line endings for you. MailManagerInterface->mail() sets this to an empty array when the hook is invoked. The array may contain either strings or objects implementing \Drupal\Component\Render\MarkupInterface.
- from: The address the message will be marked as being from, which is set by MailManagerInterface->mail() to either a custom address or the site-wide default email address when the hook is invoked.
- headers: Associative array containing mail headers, such as From, Sender, MIME-Version, Content-Type, etc. MailManagerInterface->mail() pre-fills several headers in this array.
$params: An array of parameters supplied by the caller of MailManagerInterface->mail().
