<p>Per-user mailbox quota rule is defined in Dovecot, in one of below files:</p>
<ul>
<li><code>/etc/dovecot/dovecot-mysql.conf</code>: MySQL backend</li>
<li><code>/etc/dovecot/dovecot-pgsql.conf</code>: PostgreSQL backend</li>
<li><code>/etc/dovecot/dovecot-mysql.conf</code>: MySQL backend</li>
</ul>
<p>If no per-user quota rules found, Dovecot will use 'quota_rule[X]' defined in
<code>/etc/dovecot/dovecot.conf</code>. For example:</p>
<pre><code># File: /etc/dovecot/dovecot.conf
plugin {
quota = dict:user::proxy::quotadict
quota_rule = *:storage=1G
#quota_rule2 = *:messages=0
#quota_rule3 = Trash:storage=1G
#quota_rule4 = Junk:ignore
...
}
</code></pre>
<p>So, if you want to ignore quota of <code>Trash</code> folder, you can add new quota_rule
in either <code>/etc/dovecot/dovecot.conf</code> or <code>/etc/dovecot/dovecot-{mysql,pgsql,ldap}.conf</code>.</p>
<ul>
<li>Sample setting #1:</li>
</ul>
<pre><code># File: /etc/dovecot/dovecot.conf
plugin {
quota = dict:user::proxy::quotadict
quota_rule = *:storage=1G
quota_rule2 = Trash:ignore
...
}
</code></pre>
<ul>
<li>Sample setting #2:</li>
</ul>
<pre><code># File: /etc/dovecot/dovecot-ldap.conf
user_attrs = ...,mailQuota=quota_rule=*:bytes=%$,=quota_rule2=Trash:ignore
# File: /etc/dovecot/dovecot-mysql.conf, or dovecot-pgsql.conf
user_query = SELECT ... \
CONCAT('*:bytes=', mailbox.quota*1048576) AS quota_rule \
'Trash:ignore' AS quota_rule2 \
FROM ...
