Can you build syslog-ng from source? It would be great, if you tested the PR.</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am using TLS over TCP connection to forward my syslog events to a remote server.</div>
<div>My remote server uses SNI (Server Name Identification) to route connections/events to one of the available backend servers.</div>
<div><br>
</div>
<div>I observe that syslog-ng doesn't send SNI during TLS handshake.</div>
<div><br>
</div>
<div>How can I enable it?</div>

<div>My configuration is as follows:</div>
