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!
