<h1>Backend: queuedir</h1>

directory. The files are written to temporary files with unique
filenames and moved into the final directory when the contents are
complete.</p>
<p>The file format is as follows:</p>
<ol>
<li>The envelope sender address, followed by a NUL byte.</li>
<li>A list of envelope recipient addresses, each followed by a NUL byte.</li>
<li>A terminating NUL byte.</li>
<li>The full message data.</li>
</ol>
