Dovecot will store them where you tell it to. You could have easily
stored them all in a single directory like /var/virtual/mail/user, or
even used a hashed directory scheme (which might be desirable for very
large installations like ISPs)...

Storing mail in a database sounds interesting, but it *will* introduce a
very noticeable performance hit, there is simply no way around it...

And dovecot... and 2.0 will have even better integration.

While dovecot+sieve does require a 'home' directory for sieve to work,
it doesn't have to be the users real home directory, and with
dovecot-LDA+sieve, you can safely reject at smtp time, and its vacation
message system is very sane (doesn't send vacation messages when it
shouldn't, like to mail lists, etc)...
