Editing default zimbra folders?

Question

IMAP

how to change the default folders on the server so that when you start a new user, he will have not only the sent, inbox, deleted folder,
but some other default ones
like facebook, skype, etc.
+ I would also like (but this is ideally of course)
that when creating a user, rules would be created, some default ones
, let's say this:
letters with the facebook domain were moved to the facebook folder
