public function LoggerMail::format in Helper 8

Formats a message prior to sending.

Allows to preprocess, format, and postprocess a mail message before it is passed to the sending system. The message body is received as an array of lines that are either strings or objects implementing \Drupal\Component\Render\MarkupInterface. It must be converted to the format expected by mail() which is a single string that can be either plain text or HTML. In the HTML case an alternate plain-text version can be returned in $message['plain'].

The conversion process consists of the following steps:

Parameters

array $message: A message array, as described in hook_mail_alter().

Return value

array The formatted $message.

Overrides MailInterface::format
