| − | ==Postfix How To: Local Host-only mail delivery==
| |
| − | | |
| − | ==What is postfix?==
| |
| − | Well, I think the postfix website gives a good enough definition for our purposes.
| |
| − | | |
| − | "Postfix attempts to be fast, easy to administer, and secure, while at the same
| |
| − | time being sendmail compatible enough to not upset existing users. Thus, the
| |
| − | outside has a sendmail-ish flavor, but the inside is completely different."
| |
| − | -- http://www.postfix.org/
| |
| − | | |
| − | ==Goals==
| |
| − | The goal of this how to is to setup postfix for local mailbox delivery only.
| |
| − | | |
| − | ===Required packages:===
| |
| − | *postfix
| |
| − | | |
| − | ==Postfix Installation==
| |
| − | ===Step 1: Install Postfix===
| |
| − | | |
| − | [root@computer]# pacman -Sy postfix
| |
| − | | |
| − | | |
| − | ===Step 2: Check /etc/passwd, /etc/group===
| |
| − | Make sure that the following shows up in /etc/passwd
| |
| − | | |
| − | postfix:x:73:73::/var/spool/postfix:/bin/false
| |
| − | | |
| − | | |
| − | Make sure that the following shows up in /etc/group
| |
| − | | |
| − | postdrop:x:75:
| |
| − | postfix:x:73:
| |
| − | | |
| − | Note: Postfix can be made to run in a chroot. This document does not currently cover this. Might be added later.
| |
| − | | |
| − | ==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
| |
| − | or
| |
| − | 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 (direcory tree, one message per file); if it doesn't, the mbox format is used (all mail in one file).
| |
| − | | |
| − | Examples:
| |
| − | 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/rc.conf===
| |
| − | Add postfix to the daemons list. Make sure you put it after the network has started.
| |
| − | | |
| − | ===Step 3: 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. This creates the map file that postfix understands.
| |
| − | | |
| − | postalias /etc/postfix/aliases
| |
| − | | |
| − | In addition, create .forward in /root with the contents of the user you want to forward all root mail to:
| |
| − | eg USER@localhost
| |
| − | | |
| − | ===Step 4: Start the daemon===
| |
| − | | |
| − | postfix check
| |
| − | | |
| − | If '''postfix check''' returns no errors, then start the daemon.
| |
| − | | |
| − | /etc/rc.d/postfix start
| |
| − | | |
| − | Check /var/log/mail.log for any errors.
| |
| − | | |
| − | ===Step 5: 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 6: Test some more!===
| |
| − | Make sure root mail forwards to the desired user; use the same test as above, but substitute root for user.
