I received emails from my Mobile phone provider (called hollandsnieuwe.nl) and I cannot view the content of the mail, as the mail body seems to be empty.
But it's not empty, it seems to be an encoding issue as if forward the email the message body appears.
The mail body is a single part, Mime encoded with Base64.
MIME-Version: 1.0
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: base64
Content-Length: 47809
(I can send you the whole raw email message)

I haven't experienced this issue with other mail senders yet. I have notified my mobile phone provider but I don't think they will change anything.

Is this a known issue with yahoo mail and is there more information I can send to my mobile phone provider?

Best Regards,

Ruudt Swaanen.
