This is a DRAFT, still working in progress. Don't try it on production server.

Summary

Requirements

• iRedMail-0.8.2 or later releases.

Prepare Jail

• Install ezjail:

# cd /usr/ports/sysutils/ezjail/
# make install clean

• Add below setting in /etc/rc.conf:

# Start ezjail while system start up
ezjail_enable="YES"

# Set security.jail.allow_raw_sockets=1 to allow PostgreSQL initial database.
jail_sysvipc_allow="YES"

• Reboot system is required after changing /etc/rc.conf.

# reboot

• After system start up, create Jail for domain name mx.example.com, bound to internal IP address 172.16.122.244. All files are placed under /jails/mx.example.com:

# ezjail-admin create -r /jails/mx.example.com mx.example.com 172.16.122.244

• Start Jail.

# /usr/local/etc/rc.d/ezjail restart

• List all Jails:

# jls
   JID  IP Address      Hostname                      Path
    10  172.16.122.244  mx.example.com              /jails/mx.example.com

It shows JID 10 of our newly created Jail in the command output, we can now enter this Jail with command jexec.

# jexec 10 sh

• In Jail, update /etc/resolv.conf with valid DNS server address(es). For example:

nameserver 172.16.122.2

• In Jail, install binary package bash. Required by iRedMail.

Jail # pkg_add -r bash-static

• Start iRedMail installer with your Jail ip address:

Jail # bash
bash # cd /root/iRedMail/
bash # LOCAL_ADDRESS='192.168.1.2' bash iRedMail.sh
