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 “firstname.lastname@example.org”
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.
alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix luser_relay = email@example.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
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 firstname.lastname@example.org exists.
localhost : dev.k2patel.com local:email@example.com k2patel.com smtp:vmail.k2patel.com * local:firstname.lastname@example.org
You need to create hashmap of this file use following command if you dont know how to.
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.
# Person who should get root's mail root: email@example.com backup: root user1: firstname.lastname@example.org user2: email@example.com k2patel: firstname.lastname@example.org
Also you need to rebuild alias database please use following command if you dont know.
