Java EE (Java Enterprise Edition) General Discussion

I need help with my application. I am sending a regular mail using an SMTP server to a cell phone using a destination email like phonenumber@tmomail.net for example.
My message gets to the cell phone successfully, but not formatted properly:
In my cell phone Inbox category I see some number:
502
and the message looks like this:
sender@senderhost.com/Subject line/Message body
What I want to see is:
sender@senderhost.com in the inbox folder
and the message should not contain the sender:
Subject line/Message body

I now this is possible to do because it works when I send the message from yahoo or gmail for example, but my code doesn't do it right.
Any help is apreciated.
