Quoting Tim Piessens <tim.piessens@xxxxxxxxxx>:

Hi all,

I have created a murder cluster containing 1 update server, 1 frontend and 2 backends.
Mail reading woks ok, also moving folders between backends.
However when a client creates a new folder, it gets created on the frontend and not on a backend.

Is this an Admin user? If a normal user creates a new folder it should be created on the same
backend+partition as the inbox of the user.

No, this is worrying me. It happens to all users. logging in :

[root@imap ~]# cyrus mupdatetest mupdate

S: A01 OK "Authenticated"

Authenticated.

Security strength factor: 56

A1 FIND "user.piessens.Personal"

A1 MAILBOX {22+}

user.piessens.Personal {28+}

mailserv.icsense.com!default {19+}

piessens lrswipcda

A1 OK "Search completed"

A3 FIND "user.piessens.Personal.Test3"

A3 MAILBOX {28+}

user.piessens.Personal.Test3 {27+}

imapfe1.icsense.com!default {19+}

piessens lrswipcda

A3 OK "Search completed"

I am using cyrus-imapd version 2.5.10 from debian testing

# My frontend Configuration
configdirectory: /var/lib/cyrus
proc_path: /run/cyrus/proc
mboxname_lockpath: /run/cyrus/lock
mupdate_config: standard
default server:imapbe2.***

Options in imapd.conf don't contain space. Not sure if it matters in this case

This was due to my mail client trying to autocorrect the spelling. This is not real in my set-up

server list:imapbe1.*** imapbe2.***

see above

partition-default: /var/spool/cyrus/mail
altnamespace: yes
unixhierarchysep: no
lmtp_downcase_rcpt: yes
admins: cyrus root murder
proxyservers: cyrus murder

quoting man imapd.conf
proxyservers: <none>

A list of users and groups that are allowed to proxy for other users, separated by spaces. Any user listed in this will be allowed to login for any other user: use with caution. In a standard murder this option should ONLY be set on backends. DO NOT SET on frontends or things won’t work properly.

It looks like this was the root cause. i need to test this further, but omitting these settings seems to have fixed the issue

A2 FIND "user.piessens.Personal.Test6"

A2 MAILBOX {28+}

user.piessens.Personal.Test6 {28+}

mailserv.icsense.com!default {19+}

piessens lrswipcda

A2 OK "Search completed"

Thanks a lot for the fast response.
