<div> Chen's question made me recheck the docs and now I have a doubt.
Could you please clarify under what user the LMTP-delivered
mails enters Cyrus when "<span class="font" style="font-family:"Courier New"">-a</span>"
option is used over TCP with lmtpd (i.e. <span style="">lmtp cmd="lmtpd -a" listen="127.0.0.1:2004"</span>)?<br></div>
<div> <br></div>
<div> The documentation
(<a href="https://cyrusimap.org/imap/concepts/overview_and_concepts.html#local-mail-transfer-protocol-lmtp">https://cyrusimap.org/imap/concepts/overview_and_concepts.html#local-mail-transfer-protocol-lmtp</a>)
says:<br></div>
<div> <br></div>
<div> <br></div>
<blockquote><div>For final delivery via <i>LMTP over a TCP socket,
it is necessary to use LMTP AUTH</i>. This is accomplished
using SASL to authenticate the delivering user. If your mail
server is performing delivery via LMTP AUTH (that is, using a
SASL mechanism), you will want their authentication id to be
an LMTP admins (either via the admins imapd.conf option or via
the <service>_admins option, typically lmtp_admins).<br></div>
<div> <br></div>
<div> Alternatively you may deliver via <i>LMTP to a unix domain
socket</i>, and <i>the connection will be preauthenticated
as an administrative user</i> (and access control is
accomplished by controlling access to the socket).<br></div>
</blockquote><div><br></div>
<div>But it doesn't say anything about the "-a:<i>Preauthorize
connections initiated on an internet socket</i>, instead of
requiring LMTP AUTH."

<pre>Hi Chen,
<br></pre><blockquote type="cite"><pre>So, the question : is it possible to set specific ACLs on autocreated
folders ? (i.e., ACLs, different from those defined by defaultacl in
imapd.conf).
<br></pre></blockquote><pre>I believe the autocreate mechanism has no particular knowledge of ACLs all all. It just uses the standard Cyrus policy for assigning them, with no way to override it.
Cheers,

This question has been asked twice before by different users, but no
answer has ever be given.
In 2012 : <a href="https://www.spinics.net/lists/info-cyrus/msg14612.html">https://www.spinics.net/lists/info-cyrus/msg14612.html</a>

I guess the answer is NO, but just the same I thought i'd asked again to
be sure.
So, the question : is it possible to set specific ACLs on autocreated
folders ? (i.e., ACLs, different from those defined by defaultacl in
imapd.conf).
Thanks,
Chen
