I'm trying to send a multipart message to blackberries through the blackberry internet service. My blackberry receives other multipart emails fine, but this one is not working. I have tested on other blackberry devices using the Blackberry Internet Service as well.
On all devices, I get the error message "Error parsing this message. Couldn't display the body part!!!" and none of the email content is shown.
I thought it might be character encoding for the HTML, but I am receiving other utf-8 email messages fine. I even changed my html content to just "aaa" with no markup, and that didn't work either, so I'd assume the issue is somewhere in the headers (contrary to the error message).
Has anyone encountered this issue and resolved it successfully?
