On your blackberry application list you should have 3 different messages folder. The folder labeled messages will have both email and sms/mms messages inside. Your SMS/MMS folder will have only text and multimedia messages. Then your email folder which will be labeled with your email address should have only your emails inside. Since you state that none of your emails are going to email folder, follow these steps to see if you can separate the way your message folders are separated:
Use one message list or multiple message lists
By default, your BlackBerry® device theme determines whether SMS text messages appear in the same message list as email messages.
