I've found an issue in Thunderbird. In certain email messages - sent from icloud.com, containing image embedded in email body (Content-Disposition: inline) - message body is blank. I only see the header and attachments that have "Content-Disposition: attachment". So, it looks like sender sent only attachment without text. Text could be viewed only by looking to the source code of message. And that's very bad option for inexperienced users within our organization.

type="multipart/alternative";;I know that's mainly icloud's fault, but other email clients like Outlook or Windows Mail renders the same message without any trouble.
Any ideas how to fix this ? Thank you in advance.
