New mail notification in Kmail (kde 4.2.2)

[Martin Kho]

Hi,

I've set up Kmail as a IMAP-client for gmail. No notification message pops 
up, when new mail arrives. To see if there is new mail, I've to enter all  my 
folders. Under Settings --> Configure notifications I've chosen to get a pop 
up a notification message and a mark on the taskbar.

Anyone else seen this behavior?  Can I alter this? Or ... is it a 
bug/regression?

Thanks,

Martin
