3) when i select an intrans mail it should show the mail contents

4) actually, it does not. Instead the first mail shows a mail that i seem to have received long time ago. The following mail is empty, then the following mail has weird characters...

To cure it i left click on "intrans mails" then i click on "rebuild index", i wait then it is ok
