Hello,

My last question is about having a default user for a domain. Let's take
an example to explain my question...

1. My postfix is receiving emails for foodcompany.com, securebank.com
and booksreadingassociation.org

    * securebank.com has got 10 emails, any invalid email has to be rejected
    * foodcompany.com has got 5 emails, but want to receive all other
      ("invalid") emails on a 6th mailbox
    * booksreadingassociation.org wants to received any email
      (*booksreadingassociation.org) on one mailbox

2. My postfix is configured the following way :

# our domains (foodcompany.com, securebank.com and
booksreadingassociation.org)
virtual_mailbox_domains = ldap:/etc/postfix/ldap-domains.cf
# our aliases (infosecurebank.com goes to ssmithsecurebank.com)
virtual_alias_maps = ldap:/etc/postfix/ldap-aliases.cf
# our accounts (10 for secure bank, 5 for food company)
virtual_mailbox_maps = ldap:/etc/postfix/ldap-accounts.cf
# cyrus is used
virtual_transport = cyrus
cyrus_destination_recipient_limit=1

3. As far as I understand, my config is "Postfix virtual MAILBOX
example: separate domains, non-UNIX accounts" ?

4. I solved the problem for booksreadingassociation.org (all emails in
one account) :
added and alias from "booksreadingassociation.org" to
"booksbooksreadingassociation.org" and created an acocunt
"booksbooksreadingassociation.org"

5. But my problem is how to do the foodcompany.com config :

    * Postfix should FIRST check :
          o johnfoodcompany.com
          o jamesfoodcompany.com
          o peterfoodcompany.com
          o laurafoodcompany.com
          o charlesfoodcompany.com
    * And then put ALL THE REST to :
          o othersfoodcompany.com

Because if I add "foodcompany.com" to aliases, then all emails
(including the 5 mailboxes) are going to "othersfoodcompany.com".
Of course, this is because Postfix FIRST checks for aliases and THEN for
mailboxes...
I also tried to put "foodcompany.com" as an account but it doesn't
work, it seems that postifx checks for "foodcompany.com" only in aliases ?

Thanks a lot for your help, I know it's not an easy question... I
although think that someone knowing well what postfix does in which
order could help me, we have to find where postifx looks AFTER
virtual_mailbox_maps, or something like that...
