function Message::getPreparedHeaders

1 method overrides Message::getPreparedHeaders()

DraftEmail::getPreparedHeaders in vendor/symfony/mime/DraftEmail.php

Override default behavior as draft emails do not require From/Sender/Date/Message-ID headers. These are added by the client that actually sends the email.
