I started the http api on dovecot configuration but following the documentation available here : https://doc.dovecot.org/admin_manual/doveadm_http_api/ I dont see anything regarding the acl permissions ? do we have to use a specific command ? how to manage a user acl permissions ( change the content of dovecot-acl file ?

Hi, I have read elsewhere that the Maildir shouldn’t be at the home. But that’s how it worked for me since the start. I wonder if I could either change the location of these .dovecot.lda-dupes, or if I could change home without having to move the mailboxes of all the users. Today I have this: On my dovecot-sql.conf.ext: iterate_query = SELECT username AS user FROM mailbox user_query = SELECT CONCAT('/var/mail/vmail/',maildir) AS home, \ CONCAT('maildir:/var/mail/vmail/',maildir,':INDEX=/var/vmail-index/index/%d/%n:CONTROL=/var/vmail-index/control/%d/%n') AS mail, \ 5000 AS uid, 5000 AS gid, CONCAT('*:bytes=',quota) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = 1 password_query = SELECT username AS user,password FROM mailbox \ WHERE username = '%u' AND active=‘1' On my 10-mail.conf mail_location = maildir:/var/mail/vmail/%d/%n:INDEX=/var/vmail-index/index/%d/%n:CONTROL=/var/vmail-index/control/%d/%n If I add `Maildir` to the mail_location and to the mail user_query, will I have to move mailboxes, or the only thing I have to do is to add “Maildir” when I use %h/%%h? Best, Francis

Never mind, I found it. I had to add `replication_dsync_parameters`, with the default values, but with `-x shared` to exclude the namespace. Best, Francis

Hi, Since I enabled shared mailboxes I'm having these errors: Sep 27 21:22:41 doveadm(francis(a)med-lo.eu): Error: Failed to access mailbox dovecot/lda-dupes: stat(/var/mail/vmail/med-lo.eu/francis/.dovecot.lda-dupes/tmp) failed: Not a directory And replication stopped. How can I fix this? Best, Francis

Separators and shared namespaces
by martin f krafft 27 Sep '23

27 Sep '23

Hello, I am running Dovcecot 2.3.19 on Debian, and I am trying to get shared to work. It's working if I do this: ``` namespace { type = shared separator = / prefix = Team/%%u/ location = maildir:%%h/Maildir:INDEX=%h/Maildir/Team/%%u:INDEXPVT=%h/Maildir/Team/%%u subscriptions = no list = children } ``` After setting some ACLs, I now have the following in `LIST` output: ``` … . LIST "" * * LIST (\HasNoChildren) "/" INBOX […] * LIST (\Noselect \HasChildren) "/" Team/rechnungseingang(a)example.org * LIST (\HasNoChildren) "/" "Team/rechnungseingang(a)example.org/Archiv bearbeitete Rechnungen" . OK List completed (0.003 + 0.000 + 0.007 secs). ``` However, since I am using Maildir, the default separator is `.`, and so I have to change the separator for the `inbox` namespace, which makes me feel uneasy. The system still uses `.dotted.notation` on the filesystem despite the namespace change, and subfolders and all still work, but it still rubs me the wrong way to do this. And yet, when I try to use `.` like this: ``` separator = . prefix = Team.%%u. location = maildir:%%h/Maildir:INDEX=%h/Maildir/.Team,%%u:INDEXPVT=%h/Maildir/.Team.%%u ``` then nothing shows up in `LIST` output. Any idea why this might be?

Hi, When I used a ‘.’ as a separator, it seemed to truncate paths with the domain name, such as those with %%d. That happened only to shared namespaces. Best, Francis

Exclude shared mailboxes from replication
by Francis Augusto Medeiros-Logeay 27 Sep '23

27 Sep '23

Hi, I was wondering if it is possible to exclude shared mailboxes from replication. I have userb(a)mydomain.com sharing mailboxes to usera(a)mydomain.com. However, since both mailboxes already replicate to a backup server, I wonder if it is possible to exclude the replicated mailboxes from syncing. Best, Francis

is dovecot 2.3.20 compatible with YESCRYPT?
by Andrew Hoff 26 Sep '23

26 Sep '23

To Whom It May Concern, Fedora 38 uses YESCRYPT by default to create the passwords stored in "shadow". The prefix is "$y$". Ref: https://doc.dovecot.org/configuration_manual/authentication/password_scheme… The nearest supported password scheme is blowfish. Can dovecot 2.3.20 read passwords created with YESCRYPT?

Re: expunge & sh error

From: "Данила Колесников" <d1kolesnikov(a)gmail.com> > I would like to expunge Inbox mailbox every 60 days > This mailbox is not in the config any I try to use "doveadm expunge". > But my sh configs doesn't works: Fatal: Invalid search date parameter: 60d > If I enter the contents of the config directly into the console - > everything works correctly > the same code in sh - ends with an error. This sounds like a shell parsing error rather than a dovecot bug. What is the exact command you are using? Are you trying to empty your INBOX every 60d, or rather, remove messages older than 60days? If the former, you can probably just delete the entire INBOX folder or mailbox via filesystem commands as an alternative. Joseph Tam <jtam.home(a)gmail.com>

Re: All list=yes namespaces must use the same separator - don't they?

It works everywhere now. I guess it just needed its sweet time.
