correct me if I'm wrong, but as good as haraka looks (and it looks great), it isn't really a "complete package" like the GP was looking for...

From the Manual page[0]:

> Haraka makes no attempt to be a mail store (like Exchange or Postix/Exim/Qmail), a LDA, nor an IMAP server (like Dovecot or Courier). Haraka is typically used with such systems.
