I configure all of my domains as virtual_alias_domains in Postfix:
virtual_alias_domains = /etc/postfix/vhosts
/etc/postfix/vhosts is simply a text file listing my domains:
example.com
example.net
example.org
Then I explicitly map all addresses for each domain in virtual_alias_maps:
virtual_alias_maps = hash:/etc/postfix/virtual
/etc/postfix/virtual maps each address to unique users (or aliases in
alias_maps):
postmaster@xxxxxxxxxxx admin
joe@xxxxxxxxxxx joe
sales@xxxxxxxxxxx joe
postmaster@xxxxxxxxxxx admin
joe@xxxxxxxxxxx joe
joe.smith@xxxxxxxxxxx joe
postmaster@xxxxxxxxxxx admin
joe@xxxxxxxxxxx joe
joseph@xxxxxxxxxxx joe
jane@xxxxxxxxxxx jane
In this example, joe corresponds to the Cyrus mailbox user.joe, but
admin is expanded in /etc/mail/aliases to other users (both local and
external). Final delivery is done via LMTP to Cyrus:
mailbox_transport = lmtp:unix:/var/imap/socket/lmtp
Sorry, I don't use LDAP, I use sasldb2 for authentication. To simplify
things, I put all users in the same realm, regardless of the email
domain(s) they belong to:
smtpd_sasl_local_domain = mail.example.net
Note that I'm using a generic realm that is portable between machines.
This is *not* necessarily the local machine's hostname (and it doesn't
even need to be a hostname, you can use just about anything you want).
One advantage of using a single realm is that I can support bare
username logins by making it the defaultdomain in /etc/imapd.conf:
defaultdomain: mail.example.net
Finally, be sure to support delivery of mixed-case addresses in
/etc/imapd.conf:
lmtp_downcase_rcpt: true
Aside from not using LDAP, my standard setup sounds identical to what
you're trying to achieve. Hopefully, this is enough to get you started.
Thanks for the assist. Unfortunately, it is not exactly what I wanted. To key-in every individual accounts in the alias will be a bit repetitive.
Instead, I found out that Cyrus already delivers according to the username, not username@xxxxxxxxxx, provided I disable defaultdomain settings and not use virtual domains.
Within the postfix, I have to declare itself that it is the final destination delivery of all the domains listed. It's in the main.cf at the "mydestination =" string. Needs to declare all the domains I'm receiving for here.
From there, postfix will deliver to cyrus according to username and straight to user's mailbox.
The LMPT tips were helpful though, which I am very appreciative.
The setback to the above solution is, you can't have virtual domains on the same machine. It'll break the unified mailbox function. You'll probably have to do aliases then. But as my requirements are unified mailbox, well it's good enough then.
Sincere regards and thanks
