Work Smart, Not Hard
drfugazi Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-like systems, written with security primarily in mind. Dovecot is an excellent choice for both small and large installations. It’s fast, simple to set up, requires no special administration and it uses very little memory.

Below you can find transcript of configuration and compilation session of Dovecot server and a script which I use for this purpose (as attachement).
Because of building mail system I need to export ZFS filesystem via NFS to other node, where postfix with deliver will save messages to mail boxes. As you can see in this installation transcript I configured whole zpool “studmail” as ZFS dataset for zone st1. Unfortunatelly, you can not simply share ZFS via NFS in non-global zone:
root@st1:~# zfs list NAME USED AVAIL REFER MOUNTPOINT studmail 301M 1.78T 28.0K none studmail/etc 4.52M 1.78T 4.19M /data/etc studmail/studmail 480K 1.78T 417K /data/studmail studmail/var 296M 1.78T 294M /data/var root@st1:~# zfs set sharenfs=rw=@192.168.X.X/32,anon=0 studmail/studmail cannot set property for 'studmail/studmail': 'sharenfs' cannot be set in a non-global zone
OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol.
The suite includes:

Dovecot Sieve is a fully rewritten Sieve implementation for Dovecot v1.2 and newer. The main reason for rewriting the Sieve engine was to provide more reliable script execution and to provide better error messages to users and system administrators. This implementation is part of the Pigeonhole project.

At first you need to download sources, unpack it and make or edit configuration script:
root@feniks:/home/soft/dovecot# su - soft soft@feniks:~% cd dovecot soft@feniks:~/dovecot% wget http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz soft@feniks:~/dovecot% gtar -zxf dovecot-1.2-sieve-0.1.17.tar.gz soft@feniks:~/dovecot% cp drf_sieve-1.2-0.1.12_conf drf_sieve-1.2-0.1.17_conf soft@feniks:~/dovecot% vi drf_sieve-1.2-0.1.17_conf

In this configuration file I set up additional paths to OpenLDAP and SSL libraries and optimalization options (for SunStudio).
I added two quite a few pages about Solaris zones installation and configuration. I suppose that example is better than lecture, so I put there transcript of almost all termininal session, on which I done this installation. So I invite you to read, ask and post comments if you want. Start here: 04. Containers (Solaris zones)
After installation and initial configuration of st1 container you need to look on working services and disable those, which are not necessary. But at first I will set up more comfortable environment to work. I will change default shell to zsh and home directory of root user. I will use GNU sed for this purpose. Remember that /usr/local directory is inherited from global zone in read-only mode.
Creation of container named st1, without resource control, with inherited standard directories and additionally inherited /usr/local dir (read only mode). Configured two network Quad Fast Ethernet cards: qfe4 and qfe5 in shared mode. Added ZFS pool (zpool) named studmail.
Solaris 10 has embedded some kind of virtualization mechanism, which is known as Solaris Zones. This is not only jail, but also resource controller for zones. I will not write about mechanism, because you can find this in documentation on Sun/Oracle sites and other blogs. I will give you some simple examples how to configure and install zone on Solaris 10.
There are few different ways to install software on UNIX/Linux systems. Almost each distribution has its own package system more or less similiar to others. Solaris has package system too, but I prefer to install service software from sources and compile it by myself. Then I can set configuration and optimization options. Here you will find transcripts of compilation sessions of various software with short description.
