Postfix relay all mail to one mailbox
To configure postfix to relay all outgoing mail to one localmailbox is very easy.Use the following settings in your /etc/postfix/main.cf and reload your postfix daemon with “sudo postfix reload”
First configure the relay of all outgoing mail to one local mailbox:
always_bcc = yourusername@localhost
Second if you want to discard all outgoing mail too you need some extra settings (this comes in handy when you are configuring a test server that must not mail to the outside world)
step 1) set a relayhost to a non-existant ip in your network
relayhost = 10.0.0.2
step 2) change the bounce queue settings so that bounced mail will be discarded instantly.
bounce_queue_lifetime = 0
maximal_queue_lifetime = 0
Now you are done! You have a test mailserver that can accept mail no matter to what e-mail adres it was addressed in the first place, deliver a blind carbon copy locally and discard the outgoing copy so that e-mail never leaves the server. You can use the command line program “mutt” to read the mail that has been delivered locally.
