imap folders index

[Bernhard Valenti]

i connect to my IMAP server that has ~8 folders, the thing is that right now i have to 
go through all the folders every few minutes to check if there is
any new mail in one of them. is there a solution for that so mutt like displays a 
message that folder X has a new mail... or is there some imap folder
index which shows the read/unread count ? ( oh and it would be cool if you can make 
mutt execute a command when a new mail arrives )

regards,
