[Dovecot] Question on Mail Formats

Hi, I am still tuning my dovecot, but I find myself very confortable with it.

I am going to structure my imap folder with a new namespace (somthing you cannot do with GMail :) and I can choose the mailbox format.

What is the difference between the two mailbox format "mbox" and "maildir"? I know mbox is older, but there is a good reason to use maildir instead?

I can get for instance some performance improvement? Better archiving?

Thank you!
