I have recently installed dovecot on a FreeBSD mailserver running postfix. But when I try to login with imap/pop3, I always get an error "stat failed: Not a directory".

Take a look at http://wiki.dovecot.org/MailboxFormat
The error you're getting is usually caused by treating an mbox (or similar format) file as a Maildir.
So, something in the path:
/usr/local/virtual/internal.domain.com/andrea
is not a directory. (Probably the whole thing -- andrea is probably a file.) So, when stat adds '/cur' to that path (which it needs to do if andrea is a Maildir), you get the 'not a directory' error.
I don't recall whether Postfix supports Maildir natively (Maildir is generally a better format than mbox -- by most accounts). On the server where I used it, we just delivered via Procmail (which does support Maildir).
postfix does deliver to maildir, provided the mailbox has a trailing slash (same note for maildrop). without a trailing slash, it's mbox.
the log suggests that he delivers to mbox. OP probably needs to append a slash to the mailbox lookup result in postfix (virtual_mailbox_maps).
