Assumptions

• You are using an Ubuntu distro.

Installation

apt-get install postfix

Configuration

1. Figure out your postfix user id

   cat /etc/passwd | grep postfix

   Yielding: postfix:x:114:129::/var/spool/postfix:/bin/false
   In this example, the userid of the postfix user is 114, see next.

1. Modify /etc/postfix/main.cf
   Add the following to the end of the file:

   virtual_mailbox_base = /var/mail/vhosts virtual_mailbox_domains = jira.myco.net virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid=100 virtual_uid_maps = static:114 virtual_gid_maps = static:114 virtual_alias_maps = hash:/etc/postfix/virtual

2. Create /etc/postfix/virtual
   If you are setup as a sub-domain (eg subdom.myco.com), its possibly useful to route any mail to the actual domain to a real user, do this with the following

   @myco.net root

3. Create /etc/postfix/vmailbox
   In order to support a common mailbox for all inbound Jira mail, create the file:

   @jira.myco.net jira.myco.net/shared/inbox

4. Create postfix database files from the configuration files
   For each of the config files, and for every change to them the following has to be run from /etc/postfix:

   postmap <configfile>

   eg

   postmap vmailbox postmap virtual

5. Restart postfix to take account of changes

   /etc/init.d/postfix restart

6. Create the virtual mailbox folders

   sudo mkdir -p /var/mail/vhosts/jira.myco.net/shared chown -R postfix /var/mail/vhosts

Testing

1. Ensure mail is installed:

   dpkg -l | grep mailutils

   If you come up empty:

   sudo apt-get install mailutils

2. Start a new console monitoring the mail.info log for useful feedback

   tail /var/log/mail.info

1. Send a test mail

   sudo mail -s "hello" test@jira.myco.net Cc: bla bla .

   You should see the following in the mail.info log:

   Sep 25 23:04:43 mypc postfix/cleanup[11799]: 18F956A0B: message-id=<20080925220443.18F956A0B@mypc> Sep 25 23:04:43 mypc postfix/qmgr[11784]: 18F956A0B: from=<root@mypc>, size=307, nrcpt=1 (queue active) Sep 25 23:04:43 mypc postfix/virtual[11801]: 18F956A0B: to=<test@jira.myco.net>, relay=virtual, delay=0.03, delays=0.02/0/0/0.01, dsn=2.0.0, status=sent (delivered to mailbox) Sep 25 23:04:43 mypc postfix/qmgr[11784]: 18F956A0B: removed

   Check the virtual mailbox file:

   cat /var/mail/vhosts/jira.myco.net/shared/inbox

   to see:

   cat /var/mail/vhosts/jira.myco.net/shared/inbox From root@mypc Thu Sep 25 23:04:43 2008 Return-Path: <root@mypc> X-Original-To: test@jira.myco.net Delivered-To: test@jira.myco.net Received: by trippy (Postfix, from userid 0) id 18F956A0B; Thu, 25 Sep 2008 23:04:43 +0100 (BST) Subject: hello To: <test@jira.myco.net> X-Mailer: mail (GNU Mailutils 1.1) Message-Id: <20080925220443.18F956A0B@mypc> Date: Thu, 25 Sep 2008 23:04:43 +0100 (BST) From: root@mypc (root) bla bla

If you see this, so far so good. You have a virtual mailbox all configured. Great, but now what? Now you need to set-up a POP3 server like Dovecot, see Setting up a Dovecot POP3 server for retrieving Jira mail from a virtual mailbox.
