    Postfix+Spamassassin+Courier IMAP questions...I have no idea what I'm doing.

    I've spent a few days trying to get Postfix to work correctly, and I'm close to giving up. I went from having a regular webhost who did everything via cPanel to renting my own box through ServerPronto. No cPanel because it's too expensive. I'm using Webmin and/or Putty to configure things, and I'm very very confused. My layout:

    1 Server with 1 IP
    4 Domains (each w/ associated unix login)
    Everything in DNS appears to be fine. Each domain has a cname of (,, etc)

    I want mail delivered to /home/~user/Mail/ folder
    env (using etc/profile) has "MAIL=/home/$USER/Mail" set up
    Postfix is set to deliver to "Mail/" in the home directory

    My issues arise with mapping(s):

    Delivery: canonical or virtual mappings? I bounce between /etc/postfix/virtual and /etc/postfix/canonical to no avail.

    Sending: I want each domain to be able to send messages without the From being rewritten to the primary domain. At the same time, I don't want to be a mail relay.

    Transport mapping: Should I define domain1 :[] for each domain in /etc/postfix/transport?

    I just need the basics for a good file that will achieve my goal of each domain getting mail in its appropriate mailbox when its sent from outside.

    I CAN send from the local machine (using webmin) to the outside test address. However I just replied to those messages and they aren't showing up.

    I have issues with courier-imap but I just want to tackle the Postfix problem first, then figure out why every time I telnet ( 143) and login to immediately boots me out the instant I log in successfully.

    Any help would be appreciated. A skeletonized example would be a godsend.


    EDIT: about the mailboxes themselves: Will they be automatically created on initial message delivery or do I create them myself first? Do I create them as the user, or as root? What chmod/chgrp do I use on them?

    EDIT again: updated the entry above. The machine passes local mail fine, but outside mails bounce with "Client Host Rejected: Access Denied" from the outside mail system i attempt to send from.
