Allow get raw unparsed message (with all headers and body)

[Koc]

Please implement Message::__toString() which returns unparsed email

[drjayvee]

According to this StackOverflow post, it should be as simple as

public function __toString()
{
    $imap = $this->imapConnection->getImapStream();
    return imap_fetchheader($imap, $this->uid, FT_PREFETCHTEXT) .
        "\n" .
        imap_body($imap, $this->uid)
    ;
}
