<h1>Plugin: clamav</h1>
<hr />
<p>This plugin scans messages against a <a
href="http://www.clamav.net/">ClamAV</a> server. If the message data is
detected as having a virus, the message is rejected, and the error
response contains the virus name as detected by ClamAV. This scanner
only operates over TCP/IP sockets (either remotely or locally).</p>
<p><b>Note:</b> This plugin causes mailfront to save messages to temporary
files.</p>
<h2>Configuration</h2>
<dl>
<dt><tt>$CLAMAV_CONNECT_TIMEOUT</tt></dt> <dd>The maximum amount of time
to wait for a response when connecting to a ClamAV scanner, in
milliseconds. (defaults to <tt>$CLAMAV_TIMEOUT</tt> below)</dd>
<dt><tt>$CLAMAV_MAXSIZE</tt></dt> <dd>The maximum message size to be
scanned, in bytes. This limit is useful for avoiding overloading the
scanning system(s). If the incoming message is larger than this
threshold, a warning is printed and no scanning is done. If unset or
set to "<tt>0</tt>", there is no limit.</dd>
<dt><tt>$CLAMAV_HOST</tt></dt> <dd>The hostname of the ClamAV scanner.
If this name resolves to multiple IP addresses, all of them are tried in
sequence (starting at a random point) until one scans the message.</dd>
<dt><tt>$CLAMAV_PORT</tt></dt> <dd>Use this TCP port number for the
command/response data. (defaults to 3310)</dd>
<dt><tt>$CLAMAV_SEND_TIMEOUT</tt></dt> <dd>The maximum amount of time to
wait for the output buffer to clear when sending data to a ClamAV
scanner, in milliseconds. (defaults to <tt>$CLAMAV_TIMEOUT</tt>
below)</dd>
<dt><tt>$CLAMAV_TIMEOUT</tt></dt> <dd>The maximum amount of time to wait
for a response from the ClamAV scanner, in milliseconds. (defaults to
5000)</dd>
<dt><tt>$CLAMD_HOST</tt></dt> <dd>Sets the scanner host address if
<tt>$CLAMAV_HOST</tt> is unset.</dd>
<dt><tt>$CLAMD_PORT</tt></dt> <dd>Sets the scanner port address if
<tt>$CLAMAV_PORT</tt> is unset.</dd>
<dt><tt>$CLAMD_TIMEOUT</tt></dt> <dd>Sets the timeout value if
<tt>$CLAMAV_TIMEOUT</tt> is unset.</dd>
</dl>
<h2>Sender Action</h2>
<p>None</p>
<h2>Recipient Action</h2>
<p>None</p>
<h2>Data Action</h2>
<p>None</p>
<h2>Message Action</h2>
<p>The message is scanned when all the data has been completely
transmitted (to prevent timeout issues with sending data to the ClamAV
server).</p>
