dovecot - Oct 2008 - Postfix, Dovecot, SASL, and Virtual Domains

My saga continues, with a few interruptions, to configure a new mail 
server for several domains.

I've had one private post, and read a dozen of more HOWTOs, HOWDONEs, 
blogs, and posts on doing this but still haven't had any joy.  Not quite 
sure what I got configured incorrectly so before doing more work on this 
I'll ask if what I'm trying to do is doable.

Postfix:
   mydomain being one of the domains I'm hosting.
   myhostname will be from one of the hosted domains ... later
   no local users (except possibly root)
   Dovecot to authentication/authorize
   and Deliver to ... well ... deliver :-)

Dovecot:
   users looked up by domain in /var/mail/vhosts/%d/passwd (?)
   mail placed (after mail sieve) placed in /var/mail/vhosts/$d/$u/Maildir/

Most of the HOWTOs and friends are using PostgreSQL, LDAP, or MySQL but 
I'd like to hold off on this until I feel more comfortable and informed 
on how Dovecot, Deliver, and Postfix work together.

So am I out to lunch?  I think right now it is I'm confused on what/how 
userdb and passdb are used.  (This is my next RTFM on the list.)


Thanks for any help, suggestions, or clue-sticks!

If you're setting up a new server, I highly recommend looking at the  
HOWTO that Purple Hat has at:

<http://www.purplehat.org/?page_id=4>

I did most of what they suggested. I was migrating a host to BSD and  
re-doing my postfix/dovecot infrastructure. It was clear enough that I  
could change just what I needed to.

If you are starting from scratch, just set it up the way they say to.
