We also have customers reporting that when they forward mails from the webmail, items are disappearing (attachments, images, etc)
It only happens from the webmail. No issue when using a mail client.
Some customers are the same having the issues with UTF-8 encoding in subjects send from webmail (still waiting for it to be fixed) and due to all these issues they are moving to another service provider. Really great.
