====== Catch ALL for testing ======

During development you need scenario when all email should goes to only one email.\\
which is most important requirement for developer as they want to test email as well they need confirmation.\\

Here is what i have applied on postfix.

I am sending all email to "k2patel@k2patel.com"

==== main.cf ====
Since it is developer machine there is nothing production on that server.\\
All email goes to single user no mater where it is going including local delivery. \\

<code ini | /etc/postfix/main.cf>
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix

luser_relay = k2patel@k2patel.com

mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man

myhostname = dev.k2patel.com
mynetworks_style = host

newaliases_path = /usr/bin/newaliases.postfix

queue_directory = /var/spool/postfix

readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
sample_directory = /usr/share/doc/postfix-2.3.3/samples
sendmail_path = /usr/sbin/sendmail.postfix

smtp_tls_CApath = /etc/pki/tls/certs
smtp_tls_loglevel = 1
smtp_tls_note_starttls_offer = yes
smtp_tls_security_level = may

smtpd_banner = $myhostname ESMTP ready

prepend_delivered_header = forward

transport_maps = hash:/etc/postfix/transport
</code>


==== transport ====
Create New file which create the map for transporting email.\\
Please replace "vmail.k2patel.com" with whatever email server you want to deliver to.\\
I am using vmail.k2patel.com where my real k2patel@k2patel.com exists.

<code ini | /etc/postfix/transport >
localhost :
dev.k2patel.com local:k2patel@dev.k2patel.com
k2patel.com     smtp:vmail.k2patel.com
*       local:k2patel@dev.k2patel.com
</code>

You need to create hashmap of this file use following command if you dont know how to.

<code bash>
/usr/sbin/postmap /etc/postfix/transport
</code>

==== Aliases ====
This is where all internal redirection happens.\\
Also make sure you specify all user you want redirected mail to.\\
carefull -- check the k2patel user properly.

<code ini | /etc/aliases >
# Person who should get root's mail
root:           k2patel@dev.k2patel.com
backup:         root


user1:     k2patel@dev.k2patel.com
user2: k2patel@dev.k2patel.com
k2patel:        k2patel@k2patel.com

</code>

Also you need to rebuild alias database please use following command if you dont know.

<code bash>
/usr/bin/newaliases
</code>
