When I leave my webmail opened, it checks for new messages every 5 minutes, which works great. The only thing is that it only updates the number count next to the email folder- so it'll say Inbox (2) on the left panel. But in the center section where my email list is, the new email doesn't get displayed in the list. Shouldn't the email list get updated as well?
In my case, it is indeed updating the mail list. However, it's not putting the new messages at the proper position based on the current sorting settings. They always get placed at the top of the list. I've put a ticket into trac for this:
