|
|
</ul>

</code></pre>

|
|
<p>Notes:</p>
|
|
<ul>
|
|
<li>ClamAV and SpamAssassin will be invoked by Amavisd, so if you disable Amavisd, those two are disabled too.</li>
|
|
<li>SpamAssassin doesn't have daemon service running in iRedMail solution, so there's no need to stop SpamAssassin service.</li>
