Replication Error - Trying to Interate Users
by Antonino Sidoti 11 Dec '18

11 Dec '18

HI, My first post to this list; I am trying to configure replication between two host, both hosts are having the same errors. Using ‘dovecot log errors’ gives the following errors; Dec 11 18:05:12 Error: auth: Trying to iterate users, but userdbs don't support it (created 0 msecs ago, handshake 0 msecs ago) Dec 11 18:05:12 Error: replicator: User listing returned failure Dec 11 18:05:12 Error: replicator: listing users failed, can't replicate existing data My version of Dovecot version = 2.2.36 My Configuration is attached. Any help is greatly appreciated. Thanks

Indexer worker small bug
by André Rodier 11 Dec '18

11 Dec '18

Hello, I think I submitted this before, but I am not sure this has been addressed I am using AppArmor with Dovecot, without any issue. However, I think there is a bug in the indexer working, from what I can see, a missing trailing slash. See: ------------ Dec 09 14:35:53 portal2 kernel: audit: type=1400 audit(1544366153.379:3035): apparmor="DENIED" operation="file_mmap" info="Failed name lookup - disconnected path" error=-13 profile="/usr/lib/dovecot/indexer-worker" name="var/cache/nscd/hosts" pid=10540 comm="indexer-worker" requested_mask="r" denied_mask="r" fsuid=1001 ouid=0 ------------ The indexer worker is trying to open the file "var/cache/nscd/hosts" instead of "/var/cache/nscd/hosts", which of course fails. Can someone double check the code of the indexer worker, or this has been fixed? Thanks, André -- https://github.com/progmaticltd/homebox

QUERY string clarification
by Ralf Hildebrandt 10 Dec '18

10 Dec '18

The manpage https://wiki.dovecot.org/Tools/Doveadm/SearchQuery specifies: BODY string Matches messages, which contain string in the body part. and a bit further down: TEXT string Matches messages, which contain string in the message body. Where's the difference? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | https://www.charite.de

set seen flag and junk moving a mail manually to JUNK
by Jakobus Schürz 10 Dec '18

10 Dec '18

Hi there! I want to set the \seen and the Junk Flag to an email, which i move manually to my Junk-Folder. I tried a lot... but nothing worked like expected. I have a sieve-filter, which takes an email and copy it to a pipe to rspamc. This filter is working correctly, i get a debug-message from the script, which is called through the sieve-filter. But adding another rule (addflag "Junk"; setflag "\\seen";) to this rule is getting ignored... Here is my sieve-rule: require ["imap4flags", "vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.email" "*" { set "email" "${1}"; } addflag "Junk"; setflag "\\seen"; pipe :copy "learn-spam.sh" [ "${email}" ]; How said before, the script learn-spam.sh is called, when i move a Message via drag&drop in thunderbird from the INBOX to the Junk-Folder. But the message in the Junk-Folder is unseen, recent and has no Junk-Flag... What's wrong? BR Jakob

Sieve notify variables not working with body?
by Bambero 09 Dec '18

09 Dec '18

Hi, I want to send notification like this: if body :text :matches "*" { notify :importance "3" :message "[NOTIFY] ${1}" "mailto:test@example,com"; } The notification works but the variable ${1} seems to be empty. But in this case: if header :matches "Subject" "*" { notify :importance "3" :message "[NOTIFY] ${1}" "mailto:test@example,com"; } Everything works correct. Regards, Bambero

Mail aliases plugin not honouring namespace?
by Marc Roos 08 Dec '18

08 Dec '18

I have namespace { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace Archive { disabled = no hidden = no ignore_on_failure = no inbox = no list = yes location = mbox:/home/mail-archive/%u/ prefix = Archive/ separator = / subscriptions = yes type = private } Without aliases, folders are created at /home/mail-archive/%u/ which is expected When I am adding these mailbox aliases mailbox_alias_old = Archive mailbox_alias_new = Archives These folders are created in the default namespace .Archive .Archives.2018 .Archives Is this as expected? I am at least not expecting it.

Plugins/MailboxAlias configuration not working when not successive
by Marc Roos 08 Dec '18

This is not working because the numbering is not successive. This whole configuration implementation is of course nothing to be proud of. plugin { #setting_name = value # archive folder mailbox_alias_old = Archive mailbox_alias_new = Archief mailbox_alias_old2 = Archive mailbox_alias_new2 = Archief mappen mailbox_alias_old3 = Archive mailbox_alias_new3 = Archived messages mailbox_alias_old4 = Archive mailbox_alias_new4 = Archived mail mailbox_alias_old5 = Archive mailbox_alias_new5 = Archives # spam folder mailbox_alias_old10 = Spam mailbox_alias_new10 = Junk mailbox_alias_old11 = Spam mailbox_alias_new11 = Junk E-mail mailbox_alias_old12 = Spam mailbox_alias_new12 = Ongewenste e-mail # drafst folder mailbox_alias_old20 = Drafts mailbox_alias_new20 = Concepten } https://wiki2.dovecot.org/Plugins/MailboxAlias

doveadm move and create folders for the archive
by Michael Wagner 08 Dec '18

08 Dec '18

Hello guys, I'm on a few mailinglists, which I want to archive at the end of the year. I know the command to do this, but must I create the folders for the archive by myself or is there a switch for doveadm? I tested this, but it exits with an error about the missing mailbox. doveadm -D copy -u michael Archiv/debian-user/2018 mailbox debian-user since 365d error message: doveadm(michael): Debug: Effective uid=1000, gid=1000, home=/home/michael doveadm(michael): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir:LAYOUT=fs doveadm(michael): Debug: fs: root=/home/michael/Maildir, index=, indexpvt=, control=, inbox=/home/michael/Maildir, alt= doveadm(michael): Error: Can't open mailbox 'Archiv/debian-user/2018': Mailbox doesn't exist: Archiv/debian-user/2018 Sorry for the long lines.

Segfault when using doveadm batch -A : kick
by Apollon Oikonomopoulos 08 Dec '18

Hi, Apparently the "kick" doveadm_cmd_ver2 struct lacks a .mail_cmd member pointing to an appropriate allocation function, causing a NULL pointer dereference when used via `doveadm batch`.
