title: TLS version supported by log4j2 Syslog Appender
body: <p>I have a Syslog Appender which communicates to server on tcp with below configuration. Configured an rsyslog server which is successfully receiving the messages from client. I'm new to this log4j2 and please excuse me if I missed something obvious.</p>
  <pre><code>  &lt;Syslog name=&quot;Connector&quot; format=&quot;RFC5424&quot; host=&quot;10.10.10.10&quot; port=&quot;5822&quot; protocol=&quot;TCP&quot; appName=&quot;Connector&quot; includeMDC=&quot;true&quot; mdcId=&quot;mdc&quot; enterpriseNumber=&quot;18060&quot; newLine=&quot;true&quot; immediateFlush=&quot;true&quot; messageId=&quot;Audit&quot; id=&quot;App&quot; facility=&quot;local0&quot;&gt;
        &lt;SSL&gt;
          &lt;TrustStore location=&quot;truststore.p12&quot; password=&quot;pJAY3nVuG?&quot;/&gt;
        &lt;/SSL&gt;
      &lt;/Syslog&gt;
  </code></pre>
  <p>I'm unable to find from documentation etc. on supported TLS versions for this. What's the minimum version it supports and if there is a way we can configure it to use only TLS 1.2+?</p>
