Swift Mailer - 异步发送电子邮件

on a project with intensive emailing activity we are creating asynchronnous workflow for posting emails. Workflow consists of 2 steps:

  1. creating the message (we set Subject, From, to, body, attachments), then converting to a string via $mailer->toString() and store into database.

  2. get few latest emails from database and send them out to user(s).

String stored into database is actually valid multipart EML file (e.g. can be open with Outlook) with message headers + body.

QUESTION:

How can I send message converted toString via SwiftMailer using it's transport capabilities?

Thank you.

Example of stored string in the database:

Message-ID: <1803a1a74c7612e43d58a8ca558117f3@refactoring.local>

    There's no simple way to convert a with toString serialized message back to an Swift_Message. Instead, you should use the serialize function to convert the Swift_Message you want to store inside the database back to an string.

    $data = serialize($message);
// store inside database
// ...
// later..
$message = unserialize($message);
$mailer->send($message);
