<h3 id="enable-proxymap-in-sqlldap-query-maps">Enable <code>proxymap</code> in SQL/LDAP query maps</h3>
|

<p>Set <code>proxy_read_maps</code> in postfix, so that we can use <code>proxymap(8)</code> daemon which
|
|
is part of postfix to reduce the number of connections to MySQL/LDAP and
|
|
greatly reduces system load.</p>

<p>NOTE: They are trusted subnets (amavisd-new default setting), mail sent from

these subnets will be bypassed for anti-spam and anti-virus.</p>
|
|
<h3 id="convert-sql-columns-from-latin-to-utf8-in-policyd-database">Convert SQL columns from latin to utf8 in policyd database</h3>
|
|
<p>Convert some columns of policyd database from latin to utf8, so that we can
|
|
add non-ascii characters in <code>description</code> column.</p>
|
|
<pre><code>$ mysql -uroot -p policyd
|
|
