Sure there are threads here someplace that I haven't seen, but my searches so far have come up empty.

(i) Where does zimbra store user emails? Are they stored in maildir type directories, and if so, where?

(ii) I currently have a maildir setup using postfix + mysql + courier maildrop/imap/pop. I would like to copy over my user data to start testing out zimbra but I don't see currently how to do this in a simple way.

I guess if someone answered (i), I could easily do transfers over myself. If not, hoping there is some other way to quickly copy things over.
