[kde-linux] KMail auto-mark message as read with IMAP?

[kde at timotheegroleau.com]

Hi there,

Kmail seems to automatically be marking the messages in my IMAP account as 
read. Is there something I can set to prevent that? And how can I determine 
whether this is really an issue in kmail, or possibly in the imap server?

It's not a major problem, but because I filter some emails into folders, if 
the messages are marked read, the folder don't turn bold and I don't realize 
I have received emails I'm suppose to read :/.

Thanks,
Tim.
