<div>As far as I understand, connections are only ever preauth'd when they come in via UNIX-domain sockets, which are inherently local. What are you trying to protect, and from whom?<br></div>

<div>For what it's worth, it looks like STARTTLS used to work (at least to some degree) for preauth'd LMTP, but was explicitly disabled in 2001 by this commit:<br></div>
