|
|
<p>This tutorial is for only RHEL/CentOS 5.x, Debian 5.</p>
|
|
<h2 id="install-dovecot-12">Install Dovecot 1.2</h2>
|
|
<h3 id="on-rhelcentos-5">on RHEL/CentOS 5</h3>
|
|
<p>Dovecot 1.2 is available in <a href="https://dl.iredmail.org/yum/rpms/dovecot/">another iRedMail yum repository</a>, you should append below lines in <code>/etc/yum.repos.d/iRedMail.repo</code> to enable it:</p>
|
|
<pre><code>[iRedMail-Dovecot-12]
|
|
name=iRedMail-Dovecot-12
|
|
baseurl=https://dl.iredmail.org/yum/rpms/dovecot/rhel5/
|
|
enabled=1
|
|
gpgcheck=0
|
|
priority=1
|
|
</code></pre>
|
|
|
|
<p>Note: Because iRedMail-0.6.1 and earlier versions doesn't support dovecot-1.2, so we can't add this package in default yum repository, otherwise new installation of iRedMail (<=0.6.1) will be failed.</p>
|
|
<p>Remove dovecot-1.1. Be aware of below steps, we will update dovecot config based on config file of <code>dovecot-1.1</code>.</p>
|
|
<pre><code># cp /etc/dovecot.conf /etc/dovecot-1.1.conf
|
|
# rpm -e dovecot dovecot-sieve
|
|
warning: /etc/logrotate.d/dovecot saved as /etc/logrotate.d/dovecot.rpmsave
|
|
warning: /etc/dovecot.conf saved as /etc/dovecot.conf.rpmsave
|
|
</code></pre>
|
|
|
|
<p>Install dovecot-1.2.</p>
|
|
<pre><code># yum install dovecot dovecot-sieve dovecot-managesieve
|
|
# cp /etc/dovecot.conf /etc/dovecot-1.2.conf
|
|
# cp /etc/dovecot-1.1.conf /etc/dovecot.conf
|
|
</code></pre>
|
|
|
|
<p>Package <code>dovecot-managesieve</code> provides <code>managesieve</code> service, so we don't need <code>pysieved</code> anymore. Disable it:</p>
|
|
<pre><code># chkconfig --level 345 pysieved off
|
|
# /etc/init.d/pysieved stop
|
|
</code></pre>
|
|
|
|
<h3 id="on-debian-5">on Debian 5</h3>
|
|
<p>Append below line to <code>/etc/apt/sources.list</code>:</p>
|
|
<pre><code>deb http://backports.debian.org/debian-backports lenny-backports main
|
|
</code></pre>
|
|
|
|
<p>Install Dovecot 1.2:</p>
|
|
<pre><code>$ sudo apt-get -t lenny-backports update
|
|
$ sudo apt-get -t lenny-backports upgrade dovecot-imapd dovecot-pop3d
|
|
</code></pre>
|
|
|
|
<h2 id="update-dovecot-configure">Update Dovecot configure</h2>
|
|
<p>We need to update Dovecot config file <code>dovecot.conf</code>, it's <code>/etc/dovecot.conf</code> on RHEL/CentOS, <code>/etc/dovecot/dovecot.conf</code> on Debian 5.</p>
|
|
<ul>
|
|
<li>Remove setting <code>umask =</code>. It wasn't really used anywhere anymore.</li>
|
|
<li>Remove <code>zlib</code> from all <code>mail_plugins =</code> settings. This plugin is buggy in 1.x and will be fixed only in 2.x.</li>
|
|
<li>Change sieve plugin name <code>cmusieve</code> to <code>sieve</code> in <code>protocol lda {}</code> section.</li>
|
|
<li>
|
|
<p>Change <code>ssl_disable=no</code> to <code>ssl=yes</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>[For MySQL backend]</code> Add two more columns in <code>vmail.mailbox</code> if not present:</p>
|
|
</li>
|
|
</ul>
|
|
<pre><code>$ mysql -uroot -p
|
|
mysql> USE vmail;
|
|
mysql> ALTER TABLE mailbox ADD COLUMN enablesieve TINYINT(1) NOT NULL DEFAULT '1';
|
|
mysql> ALTER TABLE mailbox ADD COLUMN enablesievesecured TINYINT(1) NOT NULL DEFAULT '1';
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li><code>[For RHEL/CentOS]</code> Append <code>managesieve</code> service related config in <code>dovecot.conf</code>:</li>
|
|
</ul>
|
|
<pre><code># ManageSieve service. http://wiki.dovecot.org/ManageSieve
|
|
protocol managesieve {
|
|
listen = 127.0.0.1:2000
|
|
}
|
|
|
|
# Plugin: sieve. ttp://wiki.dovecot.org/LDA/Sieve
|
|
plugin {
|
|
#sieve_global_path =
|
|
#sieve_global_dir =
|
|
#sieve_before = /var/vmail/sieve/dovecot.sieve
|
|
#sieve_after =
|
|
sieve = /var/vmail/sieve/%Ld/%Ln/dovecot.sieve
|
|
sieve_dir = /var/vmail/sieve/%Ld/%Ln/
|
|
}
|
|
</code></pre>
|
|
|
|
<p>Append <code>managesieve</code> in <code>protocols =</code> section in <code>dovecot.conf</code>, like this:</p>
|
|
<pre><code>protocols = pop3 pop3s imap imaps managesieve
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li><code>[For Debian 5 (lenny)]</code> In <code>dovecot.conf</code>, move <code>sieve =</code> and <code>sieve_storage =</code> from section <code>protocol managesieve {}</code> to section <code>plugin {}</code>, and rename <code>sieve_storage</code> to <code>sieve_dir</code>:</li>
|
|
</ul>
|
|
<pre><code>plugin {
|
|
sieve = /var/vmail/sieve/%Ld/%Ln/dovecot.sieve
|
|
sieve_dir = /var/vmail/sieve/%Ld/%Ln/
|
|
# ... SKIP OTHER SETTINGS HERE ...
|
|
}
|
|
</code></pre>
|
|
|
|
<h2 id="re-enable-roundcube-sieve-rules">Re-enable RoundCube sieve rules</h2>
|
|
<p>This is needed so your users will not loose all their RoundCube sieve rules.
|
|
You need to run the following commands to mass rename the RoundCube rules and repair their links:</p>
|
|
<pre><code>find /var/vmail/sieve/ -type l -name 'dovecot.sieve' -exec rm -f '{}' \;
|
|
find /var/vmail/sieve/ -type f -name 'roundcube' -exec rename 'roundcube' 'roundcube.sieve' '{}' \;
|
|
find /var/vmail/sieve/ -type f -name 'roundcube.sieve' -execdir ln -s '{}' dovecot.sieve \;
|
