Bug 342994

When the focus in Kmail is in a folder and a New E-Mail arrives, the new mail is automatically opened by Kmail. This is a bad behaviour since the user did not voluntary opened the e-mail and hence, there is a strong probability that the new mail will finally go unnoticed.

I suggest that Kmail should refrain as most as possible to automatically open new mails, or when it does, that the new mail stays "unread" untill the user actively sees it (i.e. click on the e-mail, or on the interface with the e-mail loaded).

Reproducible: Always

Steps to Reproduce:
1. Click on a Folder and leave Kmail be (you can even minimise the windows in the systray)
2. After a time, say, a new e-mail in that folder is detected on the server, and automatically loaded in the E-mail part of the UI by Kmail.
3. The e-mail has a strong probability of going unnoticed by the user if he wasn't looking at his computer at the time and does not notice he's looking at a new one.

Actual Results:  
Some new e-mails are unnoticed, or less problematic, the user doesn't know he/she a new e-mail.

Expected Results:  
Kmail should not automatically load e-mails, or, doing so, should not mark them as "read". Put otherwise, the user doesn't care that Kmail read the e-mail, but whether he/she read the e-mail, and those are two different things.
