Hi Ellie,
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 "-a" option is used over TCP with lmtpd (i.e. lmtp cmd="lmtpd -a"
listen="127.0.0.1:2004")?
The documentation
(https://cyrusimap.org/imap/concepts/overview_and_concepts.html#local-mail-transfer-protocol-lmtp)
says:
For final delivery via /LMTP over a TCP socket, it is necessary to
use LMTP AUTH/. 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).
Alternatively you may deliver via /LMTP to a unix domain socket/,
and /the connection will be preauthenticated as an administrative
user/ (and access control is accomplished by controlling access to
the socket).
But it doesn't say anything about the "-a: /Preauthorize connections
initiated on an internet socket/, instead of requiring LMTP AUTH."
(https://www.cyrusimap.org/imap/reference/manpages/systemcommands/lmtpd.html#cmdoption-lmtpd-a).
Thanks,
Anatoli

Hi Chen,
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).
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,
ellie

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

I guess the answer is NO, but just the same I thought i'd asked again to
be sure.
