<b>NAME</b><br>
CheckSenderHost - slow.conf configuration item
<p>
<b>SYNOPSIS</b><br>
<code><ul>
CheckSenderHost = [true | false]
</ul></code>
<p>
<b>DESCRIPTION</b><br>
The CheckSenderHost slow.conf configuration item allows
the host part of the SMTP MAIL FROM: address
to be check for valitity.
<p>
If this CheckSenderHost slow.conf configuration item is declared as
true, the Milter
will check the host part of the SMTP MAIL FROM: address
and will mark it as bad if it is missing or cannot be looked up
with <i>gethostbyname</i>. Bad status is marked by setting
the <b>bho</b> event (as described in the
<a href="../slowedit/events.html">standard event set</a>).
<p>
If this CheckSenderHost slow.conf configuration item is false
(the default is false), 
the above check is skipped.
In the event you have a slow network, or slow DNS lookups,
you may wish to define this CheckSenderHost as false, because
<i>gethostbyname</i> may cause your Milter to time out and
thus to become inefective.
<p>
If your operating system lack the <i>getipnodebyname</i>(3) routine,
the following warning will print if you try to enalbe this item,
and this item will be ignored:
<ul><code>
CheckSenderHost requires getipnodebyname(). Upgrade your OS.
<code></ul>
