<p>It's recommended to use the new <strong>iRedMail Easy</strong> deployment and support
platform to deploy and keep your mail server up to date, technical support
is available through the ticket system.</p>

<h2 id="system-requirements">System Requirements</h2>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<ul>
<li>iRedMail is designed to be deployed on a <strong>FRESH</strong> server system, which
  means your server does <strong>NOT</strong> have mail related components installed,
  e.g. MySQL, OpenLDAP, Postfix, Dovecot, Amavisd, etc. iRedMail will install
  and configure them for you automatically. Otherwise it may override your
  existing files/configurations although it will backup files before
  modifying, and it may not be working as expected.</li>
<li>
<p>Many ISPs block port 25 by default, it's used for communication between
  mail servers, it must be open, otherwise your server may be not able to
  receive or / and send emails. Please contact your ISP to make sure it's
  not blocked, or ask them to unblock.</p>
<ul>
<li>Amazon AWS EC2. Request to <a href="https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/">remove the throttle on port 25</a>.</li>
<li>Google Cloud Platform.</li>
<li>Microsoft Azure.</li>
<li>Linode. Explained in the <a href="https://www.linode.com/blog/linode/a-new-policy-to-help-fight-spam/">blog post</a>,
    you can open a support ticket to request the Linode team to open it. If you <a href="https://www.linode.com/?r=b4d04083428fb99ce452d84b57253d11692a0850">sign up to Linode with our reference</a>, iRedMail Team's Linode account will receive a credit of $15-20.00. Thanks.</li>
<li>DigitalOcean. According to <a href="https://www.digitalocean.com/community/questions/port-25-465-is-blocked-how-can-i-enable-it">a post in their community</a>, <strong>SEEMS</strong> impossible to unblock port 25, that means you can <strong>NOT</strong> run mail server on DigitalOcean VPS.</li>
</ul>
</li>
</ul>
</div>
<p>To install iRedMail on OpenBSD, you need:</p>
<ul>
<li>A <strong>FRESH</strong>, working OpenBSD system. Supported releases are listed on
  <a href="https://www.iredmail.org/download.html">Download</a> page.</li>
<li>At least <code>4 GB</code> memory is required for a low traffic production mail server
  with spam/virus scanning enabled..</li>
<li>
<p>Required OpenBSD installation file sets are (replace <code>[XX]</code> by the real
  OpenBSD release number):</p>
<ul>
<li>base[XX].tgz</li>
<li>etc[XX].tgz</li>
<li>comp[XX].tgz</li>
<li>man[XX].tgz</li>
<li>xbase[XX].tgz</li>
</ul>
</li>
<li>
<p>Make sure 3 UID/GID are not used by other user/group: 2000, 2001, 2002.</p>
</li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<ul>
<li>All binary packages will be installed with command <code>pkg_add -i</code>.</li>
<li>Nginx is used as web server.</li>
<li>PF is enabled by default, with basic rules for ssh and mail services.</li>
<li>OpenSMTPd are disabled by default, replaced by Postfix.</li>
</ul>
</div>
<h2 id="preparations">Preparations</h2>
<h3 id="set-a-fully-qualified-domain-name-fqdn-hostname-on-your-server">Set a fully qualified domain name (FQDN) hostname on your server</h3>
<p>No matter your server is a testing machine or production server, it's strongly
recommended to set a fully qualified domain name (FQDN) hostname.</p>
<p>Enter command <code>hostname</code> to view the current hostname:</p>
<pre><code class="language-shell">$ hostname
mx.example.com
</code></pre>
<p>On OpenBSD, hostname is set in two files: <code>/etc/myname</code> and <code>/etc/hosts</code>.</p>
<ul>
<li><code>/etc/myname</code>: FQDN.</li>
</ul>
<pre><code>mx.example.com
</code></pre>
<ul>
<li><code>/etc/hosts</code>: static table lookup for hostnames. <strong>Warning</strong>: Please list the
  FQDN hostname as first item.</li>
</ul>
<pre><code># Part of file: /etc/hosts
127.0.0.1   mx.example.com mx localhost localhost.localdomain
</code></pre>
<p>Verify the FQDN hostname. If it wasn't changed after updating above two files,
please reboot server to make it work.</p>
<pre><code>$ hostname
mx.example.com
</code></pre>
<h3 id="choose-a-nearest-mirror-site-for-installing-binary-packages">Choose a nearest mirror site for installing binary packages</h3>
<p>iRedMail will install all required binary packages with command <code>pkg_add -i</code>
from mirror site defined in file <code>/etc/installurl</code> (FYI:
<a href="http://man.openbsd.org/installurl.5">installurl(5)</a>), If no mirror defined,
iRedMail will use the <a href="https://fastly.cdn.openbsd.org/pub/OpenBSD/">fastly CDN</a>
for package installation.</p>
<p>It's recommended to install packages from a mirror site, to reduce server
load on OpenBSD primary servers. Also, installing package from a nearest
mirror site will speed up package installation. You can find mirror list
near you on OpenBSD web site:
<a href="http://www.openbsd.org/ftp.html#http">Getting OpenBSD</a>.</p>
<h3 id="install-required-packages">Install required packages</h3>
<p>iRedMail is wrote in Bash shell scripting language, so bash shell interpreter
is required, install it first:</p>
<pre><code>pkg_add bash
</code></pre>
<h3 id="download-the-latest-release-of-iredmail">Download the latest release of iRedMail</h3>
<ul>
<li>
<p>Visit <a href="https://www.iredmail.org/download.html">Download page</a> to get the
  latest stable release of iRedMail.</p>
</li>
<li>
<p>Upload iRedMail to your mail server via ftp or scp or whatever method you
  can use, login to the server to install iRedMail. We assume you uploaded
  it to <code>/root/iRedMail-x.y.z.tar.gz</code> (replace x.y.z by the real version number).</p>
</li>
<li>
<p>Uncompress iRedMail tarball:</p>
</li>
</ul>
<pre><code># cd /root/
# tar zxf iRedMail-x.y.z.tar.gz
</code></pre>
<h2 id="start-iredmail-installer">Start iRedMail installer</h2>
<p>It's now ready to start iRedMail installer, it will ask you several simple
questions, that's all required to setup a full-featured mail server.</p>
<pre><code># cd /root/iRedMail-x.y.z/
# bash iRedMail.sh
</code></pre>
<h2 id="screenshots-of-installation">Screenshots of installation</h2>
<ul>
<li>Welcome and thanks for your use</li>
</ul>
<p><img alt="" src="./images/installation/welcome.png" width="700px" /></p>
<ul>
<li>Specify location to store all mailboxes. Default is <code>/var/vmail/</code>.</li>
</ul>
<p><img alt="" src="./images/installation/mail_storage.png" width="700px" /></p>
<ul>
<li>Choose backend used to store mail accounts. You can manage mail accounts
with iRedAdmin, our web-based iRedMail admin panel.</li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>There's no big difference between available backends, so
it's strongly recommended to choose the one you're familiar with for easier
management and maintenance after installation.</p>
</div>
<p><img alt="" src="./images/installation/backends_openbsd.png" width="700px" /></p>
<ul>
<li>If you choose to store mail accounts in OpenLDAP, iRedMail installer will
  ask to set the LDAP suffix.</li>
</ul>
<p><img alt="" src="./images/installation/ldap_suffix.png" width="700px" /></p>
<div class="admonition note">
<p class="admonition-title">To MySQL/MariaDB/PostgreSQL users</p>
<p>If you choose to store mail accounts in MySQL/MariaDB/PostgreSQL, iRedMail
installer will generate a random, strong password for you. You can find it
in file <code>iRedMail.tips</code>.</p>
</div>
<ul>
<li>Add your first mail domain name</li>
</ul>
<p><img alt="" src="./images/installation/first_domain.png" width="700px" /></p>
<ul>
<li>Set password of admin account of your first mail domain.</li>
</ul>
<p><strong>Note</strong>: This account is an admin account and a mail user. That means you can
login to webmail and admin panel (iRedAdmin) with this account, login username
is full email address.</p>
<p><img alt="" src="./images/installation/admin_pw.png" width="700px" /></p>
<ul>
<li>
<p>Choose optional components</p>
<div class="admonition attention">
<p class="admonition-title">Attention</p>
<p><strong>Which webmail should you choose?</strong> Roundcube or SOGo?</p>
<ul>
<li>Roundcube is a fast and lightweight webmail, and webmail only.
  If all you need is a webmail to access mailbox and manage mail
  filters, then Roundcube is the best option.</li>
<li>SOGo offers webmail, calendar (CalDAV), contacts (CardDAV) and
  ActiveSync. If you need calendar and contacts support, also syncing
  them to mobile or PC mail client applications, then SOGo is the one
  to go. Note: If you have many ActiveSync clients, it requires a lot RAM.</li>
<li>It's ok to install both, but you can only manage mail filters with
  Roundcube in this case, because the filter rules generated by
  Roundcube and SOGo are not compatible. You can <a href="./why.no.sieve.support.in.sogo.html">force to enable it in
  SOGo</a>, but please inform end
  users and ask them to stick to one of them for managing mail filters.</li>
</ul>
</div>
</li>
</ul>
<p><img alt="" src="./images/installation/optional_components.png" width="700px" /></p>
<p>After answered above questions, iRedMail installer will ask you to review and
confirm to start installation. It will install and configure required packages
automatically. Type <code>y</code> or <code>Y</code> and press <code>Enter</code> to start.</p>

<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>The weakest part of a mail server is user's weak password. Spammers don't
want to hack your server, they just want to send spam from your server.
Please <strong>ALWAYS ALWAYS ALWAYS</strong> force users to use a strong password.</p>
