===Step 4: Test===
Try sending an email. Even from yourself to yourself should be a good test.
mail -s test user
this is a test email.
Now check your mail using whatever client you desire.
===Step 5: Test some more!===
Make sure root mail forwards to the desired user; use the same test as above, but substitute root for user.

The goal of this article is to setup Postfix for local mailbox delivery only. See: Postfix for a virtual mail delivery configuration.

Postfix Configuration

Step 1: Edit /etc/postfix/main.cf

The only things you need to change are as follows. Uncomment them and modify them to the specifics listed below. Everything else can be left as installed by pacman.

inet_interfaces = loopback-only
mynetworks_style = host
append_dot_mydomain = no
default_transport = error: Local delivery only!

If you want to control where the mail gets delivered and which mailbox format is to be used, you can do this by setting

home_mailbox = /some/path 


mail_spool_directory some/path

mail_spool_directory is an absolute path where all mail goes, while home_mailbox specifies a mailbox relative to the user's home directory. If the path ends with a slash ('/'), messages are stored in Maildir format (directory tree, one message per file); if it doesn't, the mbox format is used (all mail in one file).


mail_spool_directory = /var/mail  (1)
home_mailbox = Maildir/           (2)

1) All mail will be stored in /var/mail, mbox format

2) Mail will be saved in ~/Maildir, Maildir format

Step 2: Edit /etc/postfix/aliases

Namely, put a username in for the the following, substituting the correct username you desire (actual system account required) for USER

# Person who should get root's mail. Don't receive mail as root!
root:           USER

Run the following command as root. This creates the map file that postfix understands.

postalias /etc/postfix/aliases

In addition, create the file .forward in /root.

nano /root/.forward

In it, specify the user to whom root mail should be forwarded, e.g. user@localhost.
