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 “”

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.

| /etc/postfix/
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
luser_relay =
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
myhostname =
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


Create New file which create the map for transporting email.
Please replace “” with whatever email server you want to deliver to.
I am using where my real exists.

| /etc/postfix/transport
localhost :

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

/usr/sbin/postmap /etc/postfix/transport


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.

| /etc/aliases
# Person who should get root's mail
backup:         root

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

Test your mail any email it should get in your inbox.
