Dovecot 2.3.6 on Solaris10: build issues, segfaults
by Joseph Tam 11 Jul '19

11 Jul '19

Hopefully, there is some fix for issue 3 which is beyond my skill to fix. Issue 1) Need recent gcc version Building Dovecot versions <=2.2.x using gcc 3.4.4 worked, but this gcc version fails to build 2.3.x properly: symptoms include compile failures and executable crashes that depended on the amount of optimization used, which is usually a sign of compiler bugs. (It could also be issue 3 in disguise.) Either way, I updated to gcc 9.1.0. Issue 2) Cannot build with --enable-… [View More]hardening Using gcc 9.1.0, "configure" step fails because fd passing was broken, but the real problem was a compilation failure when "--enable-hardening" is used. Demonstration: # echo 'int main(){char a[1]; strcpy(a,a);} ' | gcc -w -fstack-protector-strong -x c - Undefined first referenced symbol in file __stack_chk_guard /var/tmp//cc12L9zV.o (symbol scope specifies local binding) ld: fatal: symbol referencing errors. No output written to a.out collect2: error: ld returned 1 exit status I'm not sure if this is a Solaris10 fumble, but configuring "--disable-hardening" removes the "-fstack-protector-strong" compiler option, which resolves this issue. Issue 3) dovecot/doveconf segfaults on startup It crashes here while processing dovecot.conf, as does "doveconf" (settings-parser.c:1519 in setting_copy()) *dest_size = *src_size; It appears *src_size is not an 8-byte address aligned (0x5597c). It inherits this value from the calling routine as the sum of "set" (8-byte aligned) + "def->offset"=20 => misaligned address.

Hi I have set up SOLR in accordance with documentation and it runs well. I use solr like: ....... fts = solr fts_solr = debug url=http://IP:8983/solr/ (solr in external machine) ...... Is replication of this system really essential ?? Due to my tests, rollback of the solr server on external machine lasts less than minute and it is nearly non-visible from client side. On the other hand solr replication is quite complicated process and rollback or master-slave switch in this case is non-trivial … [View More]

Hello, This is my first email here. I want to understand well how dovecot is integrate with ldap in a postfix/dovecot/ldap setup. I use a debian server. More specifically what dovecot need in ldap to work. I saw we can use several "mode" related to virtual domain, etc. For "start" i only need one domain with several address. I currently use fusiondirectory for manage my ldap users. i guess i can use that schema to auto create users email (name.firstname(a)domain.tld for ie) ? I also want to … [View More]

To make the test fair, I will need to fork the relevant production groupware stack (which is now stable and in operation, with our enterprise (email) data successfully migrated from Microsoft Exchange) to a new staging server; given that the current staging server is now of a materially different configuration to the production server (where the most controlled observations of these bugs were made).

Hi, after upgrading my database I kept on getting those errors. It seems like later versions of databases have strict mode enabled by default and it must either be disabled or change the dovecot database schema. Besides the password, would anyone know what other fields must be changed to the dovecot schema and have a default value? Is there any other dovecot schema for strict mode? Lefteris

Applying Dovecot for a large / deep folder-hierarchy archive.

Hello to you all, I'd like to ask about my intended application of Dovecot to create a folder-hierarchy for storing our enterprise emails, which are treated as live data rather than archives for compliance or occasional / reactive retrieval. The data is presently not that large (a few gigabytes), but it is expected to grow rapidly. Up to this stage the data has been containedin a Microsoft Exchange mailbox (2013), and then in an offline PST. The move to the offline PST was by necessity, as the … [View More]

Re: Applying Dovecot for a large / deep folder-hierarchy archive - BUG REPORTS!
by Arnold Opio Oree 07 Jul '19

07 Jul '19

Dovecot Team, I'd like to report a number of bugs, that are to my view all critical. System: Replicated on multiple Debian 10 (Buster) systemsDovecot Version(s): 2.3.4.1 doveadm-sync -1/general 1) If DIRNAMEs are not different between command line and mail_location doveadm sync will fail, saying that the source and destination directories are the same 2) The -n / -N flags do not work, and a sync will fail strangely if location is specified in the namespace definition 3) Adds mbox to path name … [View More]under mailbox directory (where syncing from an mbox source) 4) Not having the mailboxes at source named the same as those at destination causes errors and partial sync 5) Not having the target mailboxes formatted to receive the sync (/<mailboxroot>/DIRNAME/) will cause sync errors. doveadm-sync 1) With large synchronizations UIDs are corrupted where multiple syncs are executed and the program can no longer synchronize dovecot 1) Panics and fails to expand ~ to user home: observed cases are where multiple namespaces are being used Please let me know if you need me to elaborate or to provide any further information that you may need to replicate the bugs, or if I can help in any other way. With regards to the last error that I requested help on i.e. \Noselect. This has been resolved more-or-less by the workarounds that I have implemented for the bugs reported above. I have seen a number of threads whilst researching the \Noselect issue where people have been very confused. My finding was that \Noselect is a function of the IMAP specification server-side implementation RFC3501 (https://tools.ietf.org/html/rfc3501#section-6.3.6) And for me the server was returning directories with \Noselect because the mailboxes were malformed on account of dovadm-sync errors. In order to fix this I formed a bash command to transverse the mailbox hierarchy and create the missing folders critical to the sdbox format, namely DIRNAME.

I am now at the final due action to complete our Dovecot application to our use-case, but am stuck on an issue that I cannot find any easily accessible documentation on. Generally this is what has been done: 1. Uploaded the enterprise data PST to the target groupware server.2. Prepared the server by changing the mailbox format to sdbox and the the Dovecot mail location to mail_location=/var/vmail/domain/user/mail/3. Converted the pst (on-server) to a recursive mbox hierarchy using readpst4. Executed doveadm-sync to convert mbox hierarchy data into sdbox and to copy it into the enterprise archive user's mailboxes4.i. The biggest issue I faced at this point was doveadm-sync saying that the source and destination pointed to the same location, whereas they clearly did not. 4.i.a. I resolved this by removing the location= setting from the target namespace, and allowing it to default to mail_location = setting, and then using a completely different DIRNAME for the import doveadm-sync execution (which was the desired final DIRNAME); I then once the sync had been successful, changed the mail_location DIRNAME so that it pointed to the imported mail DIRNAME; and hence the imported email data was in the live mailboxes4.i.b. doveadm-import failed several times, and was throwing quite inexplicable errors, so I moved onto doveadm-sync4.i.c. I also had to make sure that the source and destination folder names matched, otherwise doveadm-syc threw very many errors and only partially imported the data4.i.d. An issue which I decided just to live with is that an mbox DIRNAME was added to each mailbox as well as the DIRNAME specified so the path to mail is mbox/dbox-Mails. My thought is that with the data live on an IMAP server it will be possible to do a dysync through TCP to correct this problem. The final issue that I am facing now, is that when readpst finds empty folders in the source pst hierarchy, it does not create an mbox file in the mbox hierarchy folder space. This causes doveadm-sync to not create the target data required for its mailbox structure i.e. DIRNAME sub- folder and index file (with our configuration). At this point either doveadm-sync or the dovecot process makes these empty folders not selectable. The question now is how would I go about making all of these folders selectable, e.g. with an internal or external command line tool to change flags / create necessary sdbox mailbox constituent data?

Dovecot appears to be trying to deliver the message to user1 while using the index directory of user2n.

Dovecot/MSQL issue
by Nathan 03 Jul '19

Hello, I'm trying to work through an issue that cropped up on a server I've been working on and haven't found a very good workaround. Dovecot is operating in a jailed environment. The configuration in dovecot-sql.conf.ext has been set appropriately with the host=127.0.0.1 (which works from a jailed environment) and when dovecot attempts to auth it appears to perform a reverse dns lookup and overwrites the host with the result localhost before using the msql credentials 'user'@'localhost' … [View More]

The data is presently not that large (a few gigabytes), but it is expected to grow rapidly. Up to this stage the data has been containedin a Microsoft Exchange mailbox (2013), and then in an offline PST. The move to the offline PST was by necessity, as the … [View More]

Exclude dovecot-uidlist files from a Maildir backup ?
by David Pottage 25 Jun '19

25 Jun '19

Hi, I am using restic to backup my email (stored in dovecot Maildir format) to Amazon S3 As each message is a separate file on disk, and those files don't change after the email has been delivered and read by the user, the incremental backup each day is fairly efficient as it only stored new mails. However, the dovecot-uidlist files change frequently, and are often quite large. The restic backup program detects the file has changed and uploads a new version, but is not smart enough to … [View More]

Re: Mail migration problem

Well, judging by the error message it appears like dovecot hasn't been compiled with support for maildir, which is strange because I don't see any way to disable in the compile-time options. Are you using the precompiled package from the distro or compiling dovecot by yourself? Could you share the output of "dovecot --build-options" and "dovecot --version"? Thanks!

Hi, The documentation at https://wiki.dovecot.org/UserDatabase/ExtraFields states that "It's possible to override settings from dovecot.conf", as well as the following: > If you want to override settings inside sections, you can separate the > section name and key with '/'. For example: > > namespace default { > inbox = yes > separator = . > location = maildir:~/Maildir > } > > The separator setting can be overridden by returning namespace/… [View More]

Dovecot LMTP rejecting mail from address with apostrophe
by Michal Krzysztofowicz 18 Jun '19

18 Jun '19

Hi, I have an OpenSMTPD / Dovecot installation on an OpenBSD server. I recently came across an issue where Dovecot LMTP would reject a message sent to a local user from an address which contains a single apostrophe (e.g. firstname.o'lastname(a)example.com) Apparently apostrophe, as well as a number of other special characters, are valid characters in the local part of the email address (that's everything to the left of the @ character). The message I get in the logs is: Jun 14 11:57:34 … [View More]

Problem syncing e-mails with Outlook
by Odhiambo Washington 18 Jun '19

18 Jun '19

Hello all, I am running dovecot- 2.3.5.2 with mdbox storage. I deleted the dovecot.index* from all my folders, which led to mails not being displayed. I rebuilt the indexes for all the users after that, using: doveadm force-resync -u user@domain "*" However, the problem now is that Outlook,configured for IMAP, is not able to sync the mails with the server. I can login to the server using webmail and I see all the e-mails listed. However, when I connect outlook, it does not sync all these e-… [View More]mails. I am seeing the errors below. Not sure how to fix that.

Deleted dovecot.index.*

I'm using mdbox. What's the consequence of deleting dovecot.index.* from all folders? All mail gets lost or I can rebuild the indexes and get the mails?

mailbox encryption
by David Mehler 17 Jun '19

17 Jun '19

Hello, I've got dovecot 2.3 going, and I've got a file 10-mailcrypt.conf which is loading mail_crypt, thinking that that plugin would propagate through all the services, sieve, lmtp, and mailbox message storage. I'm not seeing anything in the logs indicating that the encryption is happening. I am using a file format dbox specifically sdbox format, and in my mailbox I am seeing files like u.5 and others, a file check on them reveals them as data. Should I be seeing encryption in the logs? Thanks. Dave.

Switching to dovecot LMTP appears to have change the information in the received header, which appears to be causing my spam filter to wig out and mark local to local emails as spam.

What does Solr index do and how to handle its high avaliablity?
by luckydog xf 17 Jun '19

17 Jun '19

Hi, guys, Can you give me an example of solr usage in dovecot? As far as I know, you can search email easily by MUA like outlook, so which role does solr play? And based on https://dovecot.org/pipermail/dovecot/2019-April/115575.html I'm going to use an VIP to host 2 mail servers. Currently, it works in fail over and fail back test except solr index, so how to resolve this? Is it possible to put dovecot index on shared storage like NFS? How to if it's a yes. It seems it's under /var/… [View More]

Self-signed TLS client certificates

Dear List, I self-host my e-mail and run Dovecot since ever I do that. Dovecot version is 2.3.4.1 (f79e8e7e4), running on Debian testing. Now I am trying to configure Dovecot for client TLS certificates. I have a self-signed certificate whose private key resides on a smartcard (Yubikey, to be exact). I wanted Dovecot to accept that TLS client certificate instead of a password. So I searched and found this wiki page: <https://wiki2.dovecot.org/SSL/DovecotConfiguration#… [View More]

LMTP doesn't save to +mailbox

Since switching to lmtp in dovecot, mail to user+mailboix(a)example.com does not get saved in ‘.mailbox’ as it did with LDA, instead it gets saved into the INBOX.

Dovecot director: show user breakdown by director?

Hi, We have recently started using the director in some tests. We are using the static passdb setup (proxy=y nopassword=y) for now, where authentication is done on the downstream IMAP servers. "dovecot director status" shows a breakdown of proxied connections per backend, but there does not seem to be a similar breakdown of user connections per director. The output of "doveadm who" is empty. I assume this is due to there being no local userdb/passdb on the directors? root@xxx:/etc/… [View More]

Will MultiMaster dsync work fine or will be big problems ? I configured dovecot to dsync from serv1 to serv2 to serv3 and repeat to serv1 to serv2 to serv3 and repeat... When email received to serv2, it will be synced to serv3, and serv3 will sync it to serv1, and serv1 will sync it to serv2 and will stop here because emails matched. What problems can be with this kind of configuration ? (except that if one of server(cluster) will be stopped, sync will be stopped too until cluster is online again)

Outlook renames Junk folder
by Cliff Hayes 13 Jun '19

13 Jun '19

Hello, Some versions of Outlook will randomly rename the Junk folder to Junk Email. This of course causes errors because Dovecot can no longer store junk. I go in to Outlook for each user and add another Junk folder, so now they have Junk and Junk Email. This fix action lasts a while until Outlook decides to do it again. Is there a way to tell Dovecot that if the Junk folder doesn't exist, try sending the email to Junk Email folder? Thanks in advance.

Sieve to strip html from multipart messages

13 Jun '19

Is is possible (I’m sure it is, so how) to strip multipart messages that are HTML and text of the HTML portion and leave the bare text message without also stripping other parts (like images or attached files). Or also to take messages that are only HTML and strip the HTML and replace it with a plain text version? I used to do this a long time ago with procmail and lynx, but it was never reliable since procmail doesn’t really understand MIME.

Hi all, I am in need of some help. Straggling to make something work, trying to configure postfix and dovecote imap server with dovecote replication. Can’t figure out what is wrong with my configuration. Replication is working only for vmail user account, I am getting this error on my secondary server for all other users… dovecot: doveadm: Fatal: setgid(4015(zdokman) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This … [View More]

Sql user and maildirs
by ＠lbutlr 10 Jun '19

10 Jun '19

For many years I had the following in my dovecot.conf: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } Recently, I started having quite a lot of errors on one MySQL account (used as a bcc backup account) along the lines of Fatal: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/backup@… [View More]domain/Maildir (try prefixing it with mbox: or maildir: Messages were sitting in the mail and were also getting dumped into /usr/local/virtual/backup@domain/new and I ended up running a fun little awk to move them into the right folders: grep -r "<backup+" . |awk -F: '{t=tolower($2); f=tolower($1); gsub(/@.*/, "/", t); sub(/<backup\+/, "../Maildir/", t); sub(/\.\//, "",f); cmd="mv " f" “t; system(cmd); }’ So I changed my doevecot.conf to: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=maildir:/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } And the errors went away. So, no problem here to solve, but I am curious why I haven’t been having issues until quite recently? Was there a change or have I stumbled into something where it only looks like I’ve fixed the issue? In case it matters? # cat dovecot-sql.conf.ex [7:57] [/etc/dovecot] driver = mysql connect = host=localhost dbname=postfixusers user=dovecot password=x default_pass_scheme = SHA256-CRYPT password_query = select password FROM mailbox where username ='%u' user_query = select 89 as uid, 89 as gid, concat('/usr/local/virtual/', maildir, 'Maildir') as home FROM mailbox where username = '%u' The only ‘recent’ change I’ve made to my configuration was creating the Maildir/ subfolder for all the virtual users instead of using the ‘mailder’ from the sql table (that is, I added “, ‘Maildir’” to the concat, but that was quite awhile ago. I’m pretty sure I’d have noticed this before. Is that user_query as it should be or should I set concat('/usr/local/virtual/', maildir) as home and also set concat(‘maildir:/usr/local/virtual/', maildir, 'Maildir') as mail here rather than in the userdb block? -- K is for KATE who was struck by an axe L is for Leo who swallowed some tacks [View Less]

Re: doveconf complains No matches on !include conf.d/* line but still writes out contents in conf.d
by Ben Ma 10 Jun '19

Further investigation shows that `doveconf` called `/usr/lib/dovecot/managesieve` which in return calls `doveconf` again, but with another uid (possible? I'm not sure) and a few extra arguments, which causes a call to `glob` in `src/config/config-parser.c:settings_include` to fail with `GLOB_NOMATCH`. I'd be appreciate if anyone can provide information on suspicious permission-relating operation that `managesieve` does before calling `doveconf`.

FTS Xapian
by Daniel Miller 09 Jun '19

09 Jun '19

For my primary namespace this is working fine - thanks to the developers! It also appears to work great for shared folders as well. But my virtual folders aren't returning results - at least not to the client. The logs show FTS Xapian opening several DB files and getting results - but nothing is being returned to client. Is this a config issue on my side or is this a current limitation of the plugin? -- Daniel

Stats/Metrics in 2.3
by Nikolai Lusan 03 Jun '19

03 Jun '19

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Greetings, So the changes to the stats modules between v2.2 and v2.3 have broken some of my monitoring. I am attempting to use the new method of gathering "metrics" from "events" - but the details in the documentation are a bit thin. I started with the examples provided at https://wiki2.dovecot.org/Statistics and tried to build from there with only moderate success. What I am trying to achieve is the monitoring of login attempts (with … [View More]successes and failures as separate modules - as well as aborted attempts), user sessions an bytes transferred. All this for multiple virtual domains and users. I have attached my current /etc/dovecot/conf.d/10-stats.conf so people can see what I have attempted so far. Based on that file the output I get is: # doveadm stats dump metric_name field count sum min max avg median stddev %95 imap_login_attempt_lusan.id.au duration 0 0 0 0 0.00 0 0.00 0 imap_login_lusan.id.au_failed duration 0 0 0 0 0.00 0 0.00 0 imap_login_lusan.id.au_success duration 0 0 0 0 0.00 0 0.00 0 imap_select_no duration 702 197998 89 13942 282.05 133 1247.14 278 imap_select_no_notfound duration 702 197998 89 13942 282.05 133 1330.67 285 imap_command_list duration 14 287397 17595 25823 20528.36 20060 2194.36 25823 imap_command_select duration 1593 2354698 355 81662 1478.15 743 4583.03 4460 imap_command_search duration 0 0 0 0 0.00 0 0.00 0 imap_command_fetch_ok duration 0 0 0 0 0.00 0 0.00 0 storage_http_gets duration 0 0 0 0 0.00 0 0.00 0 Based on the metrics I have set I would expect to see entries in the first 2 lines at least, given that there are multiple users logged into the server from the monitored domain (or at least the domain I am trying to monitor to begin with).

macOS Notes.app IMAP Syncing Not Working
by Steven Smith 01 Jun '19

01 Jun '19

I’m requesting help getting macOS’s Notes.app to sync notes with a new dovecot IMAP server. Thanks to dovecot’s excellent online documentation and help from this list, I have a new perfectly functioning IMAP server. The issue is that macOS Note.app does not sync with this server. However, iOS Notes.app *does* sync and work well with this IMAP server, and the differences between macOS and iOS Notes apps are well known. (Thanks, Apple.) https://apple.stackexchange.com/questions/265579/notes-… [View More]wont-sync-via-imap-i… <https://apple.stackexchange.com/questions/265579/notes-wont-sync-via-imap-i…> https://jpmens.net/2015/09/28/experiments-using-imap-for-notes/ <https://jpmens.net/2015/09/28/experiments-using-imap-for-notes/> … I am migrating from a working Server.app system in which Notes.app syncing does work across all devices, and therefore have a working dovecot configuration from Server.app, although it does not contain an explicit configuration for the “Notes” mailbox. I would greatly appreciate any help or pointers for these questions: Does anyone have a working template for dovecot that works with macOS Notes.app? I’ve posted doveconf -n of both the new server and the old Server.app server below. Would you all be able to provide advice on TO-DO’s and NOT-TO-DO’s for mailbox/name-space reconfiguration as I try to muck around with a nicely working, deployed IMAP server? I believe that the solution has something to do with name spaces and separators, and I’ve already changed the separator from the original ‘/’ to ‘.’ on the working server without success or obvious changes. All the mail boxes on the new IMAP server look like this, *without* a prefix ‘.’: > ls -1 /var/mail/tld.domain.mail/username/mdbox/mailboxes/ > Archive/ > Deleted Messages/ > Drafts/ > INBOX/ > Junk/

[mail-crypt-plugin] Private key location in Folder Key Mode
by emordin 01 Jun '19

01 Jun '19

Hi, So I am trying to locate the private key in dovecot-attributes but I can't seem to find it. I have went thru the strings in the file with the lib-dcrypt document as a guide but the private key doesn't seem to be in there. I'm guessing the private key is an internal attribute located here '/private/vendor/vendor.dovecot/pvt' , but according to the mail-attribute.h file that location is not accessible. Is this true? Or is there a way to see the private key? Thanks. Sent with [ProtonMail](https://protonmail.com) Secure Email.

Dict issue with PostgreSQL for last_login plugin (duplicate key)

Hello, I am trying to setup the last_login plugin on Dovecot 2.3 in order to log a user's last IMAP login into a separate PostgreSQL table called last_login.

imap userdb Fatal setuid errors
by Steven Smith 28 May '19

28 May '19

I’m trying to configure dovecot lmtp in multi-user mode. My error logs are filled with messages saying that an imap process cannot do a setuid to another user: > May 21 22:28:46 imap(pid 17441 user myuser): Fatal: setuid(512(myuser) from userdb lookup) failed with euid=501(adminuser): Operation not permitted (This binary should probably be called with process user set to 512(myuser) instead of 501(adminuser)) I see that others have had similar issues, but I am not able to apply any of the … [View More]fixes or workarounds to solve this issue (e.g. setting libexec/dovecot/imap as setuid-root). I’ve also tried other fixes like setting the permissions to 0777 on the userdb auth for postfix smtpd. According to the code (restrict-access.c, linked below), it appears that when a user authenticates, an imap worker process is launched that has the bid of the authenticator. When another user authenticates, this last process is used, but it does not have the permissions to perform a setuid to the new user, resulting in the Fatal error that appears in the logs.

Race condition in IMAP NOTIFY for events received NOTIFY_DELAY_MSECS apart
by Guilhem Moulin 25 May '19

25 May '19

Hi there, There seem to be a race condition in IMAP NOTIFY: when two events for the SELECTED mailbox are received soon after one another, sometimes only the first one is being reported to clients that enabled IMAP NOTIFY. On closer look it seems like this is most often reproducible when the delay between the two events is NOTIFY_DELAY_MSECS (500ms). This is with 2.3.4.1 from Debian sid. $ sed -r 's/^\s*//; s/\s+/ /g' >/tmp/dovecot.conf <<-EOF log_path = /tmp/dovecot.… [View More]log mailbox_list_index = yes mail_home = /dev/shm/dovecot-test/%u mail_location = dbox:~/mail ssl = no EOF (`doveconf -c /tmp/dovecot.conf -n` output enclosed.) $ rm -rf /dev/shm/dovecot-test && mkdir -m0700 /dev/shm/dovecot-test $ env -i USER=user HOME=/dev/shm/dovecot-test/user PATH=/usr/bin:/bin \ doveadm -c /tmp/dovecot.conf exec imap S: * PREAUTH [CAPABILITY IMAP4rev1 … NOTIFY] Logged in as user C: a NOTIFY SET STATUS (SELECTED (MessageNew MessageExpunge FlagChange)) (MAILBOXES (INBOX test) (MessageNew MessageExpunge FlagChange)) S: * STATUS INBOX (MESSAGES 0 UIDNEXT 1 UIDVALIDITY 1558785754 UNSEEN 0 HIGHESTMODSEQ 1) S: a OK NOTIFY completed (0.004 + 0.000 + 0.003 secs). S: * STATUS INBOX (MESSAGES 0 UIDNEXT 1 UIDVALIDITY 1558785754 UNSEEN 0 HIGHESTMODSEQ 1) C: b SELECT INBOX […] S: b OK [READ-WRITE] Select completed (0.001 + 0.000 secs). Now deliver two messages to INBOX with ~500ms in between: $ env -i USER=user HOME=/dev/shm/dovecot-test/user PATH=/usr/bin:/bin sh -c \ 'echo -n . | doveadm -c /tmp/dovecot.conf exec dovecot-lda -e -m INBOX; \ sleep 0.500; \ echo -n . | doveadm -c /tmp/dovecot.conf exec dovecot-lda -e -m INBOX' Only the the first message is reported in the above IMAP session: S: * 1 EXISTS S: * 1 RECENT An UNSELECT doesn't trigger the notification, but (of course) a NOOP does: C: c NOOP S: * 2 EXISTS S: * 2 RECENT S: c OK NOOP completed (0.001 + 0.000 secs). Similarly, for two flag changes within 0.5s only the first is recorded: $ env -i USER=user HOME=/dev/shm/dovecot-test/user PATH=/usr/bin:/bin sh -c \ 'doveadm -c /tmp/dovecot.conf flags add "\\Seen" mailbox INBOX 1; \ sleep 0.500; \ doveadm -c /tmp/dovecot.conf flags add "\\Answered" mailbox INBOX 2' yields a single unsolicited FETCH response: S: * 1 FETCH (MODSEQ (4) FLAGS (\Seen \Recent)) AFAICT this is only reproducible in the ‘SELECTED’ mailbox specifier: after creating a mailbox "test", $ env -i USER=user HOME=/dev/shm/dovecot-test/user PATH=/usr/bin:/bin sh -c \ 'echo -n . | doveadm -c /tmp/dovecot.conf exec dovecot-lda -e -m test; \ sleep 0.500; \ echo -n . | doveadm -c /tmp/dovecot.conf exec dovecot-lda -e -m test' yields two unsolicited STATUS responses as expected: * STATUS test (MESSAGES 1 UIDNEXT 2 UIDVALIDITY 1558787038 UNSEEN 1 HIGHESTMODSEQ 2) * STATUS test (MESSAGES 2 UIDNEXT 3 UIDVALIDITY 1558787038 UNSEEN 2 HIGHESTMODSEQ 3) (And same thing for two flag updates in the "test" mailbox.) This is not specific to INBOX as once "test" is selected the same problem arises. AFAICT the race is in ‘src/lib-storage/list/mailbox-list-index-notify.c’ which for some reason doesn't acknowledge ST_CHANGED() after inotify_rm_watch(), but I couldn't get my head around that file.

MailCrypt plugin questions
by MRob 24 May '19

24 May '19

I read the mailcrypt plugin document on the wiki and had couple questions. 1. If I want per-user encryption am I correct I should configure global keys with all related settings override in the userdb lookup? 2. If I do not want to encrypt some user accounts, is it enough to omit the mail_crypt_global_private_key from the userdb lookup? In other word, mail_plugins still active with mail_crypt, will that cause user account to be encrypted unexpectedly if no private key is given? 3. … [View More]

Another alternative is to use the checkpassword hook that will accept any username/password. The advantage is you can do post-analysis of credentials as the script has access to them.

Catch all for dovecot authentication?
by Tobi 23 May '19

23 May '19

Hi I'm aware that there are several good reasons not to do what I want, but in my use-case it would be an interesting feature. So please no discussions about the reasonableness I have some spamtrap SMTP servers (postfix). Currently SMTP AUTH is disabled. But as I daily have thousands of AUTH tries I thought it would be nice to be able to accept any AUTH request from postfix in dovecot. Is something like this possible with dovecot? If so any good description available on how to achieve? Thanks -- tobi

How to get original recipient from Postfix when using LMTP?
by MRob 22 May '19

22 May '19

Many people prefer to use LMTP for delivery from postfix for better efficiency but X-Original-to header support still missing after many years. One affect of this is need to set sieve_vacation_dont_check_recipient = yes which violate Sieve standard and cause auto-replyies sent to messages that should not happen. Or abandon LMTP. or abandon postfix?? So while feature request is stalled are there any realistic workarounds?

In the example above $USER1$ did not have a sieve script configured but $USER2$ had one, as you can see. As a workaround, I configured an empty sieve script for all users with out sieve configured. This seems to work but actually I do not want to have users with empty sieve scripts. This bug seems to be related to https://dovecot.org/list/dovecot/2013-February/088540.html where Timo stated: "LMTP always delivers the mail to the first user. Then it tries to copy the first mail to the second user, because in some setups this can be done using hard links. With mbox that of course doesn't work, but looks like instead of failing silently it logs an error. So everything is working as it should, except there are these unnecessary errors logged. I'll see about getting rid of them." Is it possible to get rid of these error messages, either by a config setting that prevents if they do not lead to a real problem or by changing the code to avoid the behaviour described by Timo? Attached you can find doveconf -n output and the used ldap.conf (both anonymized), the referenced /etc/dovecot/passdb.deny and /etc/dovecot/userdb.overrides are usually empty files and only used during mailbox migrations.

enforcing multiple per-mailbox quotas for shared mailboxes
by Jost-Philip Matysik 20 May '19

20 May '19

Hi! I'm trying to get quotas for shared mailboxes set up on my server. It's not working, and I fail to understand why. Documentation for setup of this complexity is rather scarce on the web, and the discussions I found either don't directly apply or terminate with "I got it working" but no explanation. Can someone please help? The setup is rather lengthy and complicated, so I'll try to give a summary first for easier understanding. All help is appreciated! Please respond if you need more info! … [View More] Thanks! Best regards, Jost Basic setup (where am I coming from?): ====================================== - This is a Debian 9 system with a more recent version of dovecot installed from https://repo.dovecot.org/ce-2.3-latest/debian/stretch - users have individual mailboxes with individual quotas -- this works great! - users can share mailboxes with other users through ACLs. To achieve this, there exists a wildcarded namespace with prefix="ZZZ_Freigaben/%%u" --this also works great! ==> up to here it's pretty much following the examples from the Wiki to the letter. Configuration goal (what do I want to achieve?): ================================================ - attach quotas to mailboxes, not logins - when copying/moving mails across shared mailboxes during imap sessions, enforce quota based on target mailbox, not logged-in user doing the copying. To clarify: ==> so if Bob has a quota of 500MB, all messages in Bob's mailbox should count against (and only against!) Bob's quota, regardless of who put them there. ==> if Alice has access to her own mailbox (directly), as well as Bob's mailbox and Dave's mailbox (through sharing), she should see 3 individual quotas when logging in: her own quota (200MB) for everything in her mailbox, bob's quota (300MB) for everything in Bob's mailbox, and Dave's quota (10GB) for everything in Dave's mailbox. These 3 quotas should be completely independant and neither block, nor override each other. Setup Idea (how I tried to get there): ====================================== - "quota=..." "quota_rule" and "quota_rule2" always refer to the user's own mailbox (with an additional rule for Trash). Everyone has those, so these are loaded statically from dovecot config file. - "quota_rule" is overwritten from userdb with the user's individual mailbox quota (the more I like you, the more space you get...) - since the number of different additional quotas required per user depends on how many mailboxes are shared with that user, individual "quota2=...", "quota3=...", "quotaN=..." fields are dynamically generated by the MySQL backend and loaded from userdb upon login. - consequently, for each "quotaN=..." entry, a corresponding "quotaN_rule=*:storage=XXX" is generated and returned from userdb (substitute N=1,2,3,4,... accordingly) Observations: ============= 1. enforcing quota for the user's personal mailbox works as expected, both through IMAP and when delivering incoming mail 2. overriding "quota_rule=..." from userdb for the user's personal mailbox works great. Individual quota is recognized and enforced both through IMAP and when delivering incoming mail. 3. dynamically loading "quota2=...", "quota3=..." etc. from userdb doesn't seem to work at all! I can see them being added as extra fields in the logs upon user login, but the quota-plugin seems to completely ignore them. They are not enforces, and tools like 'doveadm quota' list the userdb fields in the debug messages, but do not interpret them in any way. They do not throw errors either, the additional quota roots are just silently ignored. 4. the end result is that in an IMAP session the logged-in user's quota is enforced for their individual mailbox, but as soon as they write to someone else's mailbox (move a mail to /ZZZFreigaben/bob/Some-Subfolder), no quota is enforced at all! Additional debugging done: ========================== if I hardcode a "quota2=" and/or "quota3=" in the config file, I can observe the following: - If I hardcode "quota2=count:some_name:ns=ZZZ_Freigaben/", dovecot and doveadm will recognize the additional quota root. But since the folder "ZZZ_Freigaben/" on its own isn't a mailbox (it's just a path CONTAINING mailboxes), the quota is neither displayed in clients, nor enforced. It has no real-word effect, other than 'doveadm quota' showing an additional line. - If I hardcode "quota2=count:other_name:ns=ZZZ_Freigaben/postmaster/" in the config file (with that path being the real IMAP path to a shared mailbox), dovecot will complain in the log saying Error: quota: Unknown namespace: ZZZ_Freigaben/postmaster/ dovecot will start and work for the most part, but again completely ignore settings for the additional quota. - additionally, trying to override "quota2_rule=..." from userdb doesn't work as it does with "quota_rule=..."! If I have both "quota_rule=..." and "quota2_rule=..." in the config file as well as returned from userdb (with different values), dovecot will use "quota_rule" from userdb, but "quota2_rule" from config file. This behavior seems inconsistent! - I tried both maildir and count backends (seperately or mixed). Both show the same behavior. - I tried appending or removing an empty "ns=" to the first "quota=..." entry (the wiki shows some examples with it, some without). Makes no difference...

Hi, I couldn't really find documentation about ssl_dh_parameters_length except for mention in passing on the page https://wiki2.dovecot.org/SSL/DovecotConfiguration For version 2.3 and above is that setting necessary? If so what are the values I can use, is setting it high like 4096 beneficial or make any problems for clients? Thanks for assistance.

How to continuously gather statistics?

17 May '19

Hello, I recently upgraded to the latest version of Dovecot, and want to use the newly introduced logging / event system. I want to fetch the statistics every couple of seconds, and push those to our logging platform. Metrics such as: number of IMAP commands, average time they took, etc. However the metrics as reported by Dovecot continously increment. So I see two solutions: - Our solution could keep track of the previous values. But that could also break if the statistics are reset … [View More]

Dovecot Separator change

Hi community, actually we are using dovecot 2.2.27 without shares mailboxes. Now we would like to implement it. So the problem is that our separator is dot „.“ and the username like „firstname.surname“. That’s doesn’t works with shared mailboxes. Are there a migration guide for changing „.“ to „/„ or it's not possible? kind regards Oliver

File-dictionary based quotas and SETQUOTA
by Ganael Laplanche 16 May '19

16 May '19

Hello, I am trying to set up file-dictionary based quotas while supporting the SETQUOTA IMAP command. I am using the following configuration : ---- plugin { quota = dict:User quota::file:%h/Maildir/dovecot-quota quota_set = dict:file:%h/Maildir/dovecot-quota } ---- which enables correct quota accounting + setting through SETQUOTA. A user's dovecot-quota file ends with the following contents : ---- priv/quota/limit/storage 5242880 priv/quota/limit/messages 20 priv/quota/messages 1 … [View More]priv/quota/storage 8506282 ---- which shows a correct accounting (1 mail received, ~8MB used) and correct setting after having used the following IMAP command through a master user : A2 SETQUOTA "User quota" (STORAGE 5242880 MESSAGE 20) *But* the problem is that I am unable to fetch the limits and consume them from userdb (as a consequence, the limits are never applied). On the consuming side, I am using a dictionary userdb to try to fetch the 'priv/quota/limit/storage' value from the file but it does not work because the key is never found. Here is my configuration : ---- userdb { driver = dict args = /etc/dovecot/dovecot-dict-quota.conf.ext } ---- and my dovecot-dict-quota.conf.ext file : ---- uri = file:%h/Maildir/dovecot-quota iterate_disable = yes key quota { key = priv/quota/limit/storage default_value = 100 } userdb_fields { quota_rule = *:storage=%{dict:quota} } ---- If I try to fetch the quota for that user : # doveadm quota get -u ganael.laplanche(a)centralesupelec.fr Quota name Type Value Limit % User quota STORAGE 8307 100 8307 User quota MESSAGE 1 - 0 the default rule is returned (100). The logs show : May 16 12:02:45 mailhost1-saclay dovecot: auth-worker(12899): Debug: dict(Ganael.Laplanche(a)centralesupelec.fr): Lookup: shared/priv/quota/limit/ storage not found, using default value 100 We can see that the default quota rule has been applied because the key is not found. The problem is that a "shared/" prefix is always prepended when looking for the key I configured (priv/quota/limit/storage). If I test the dictionary manually, the key is found : # doveadm dict get -u ganael.laplanche(a)centralesupelec.fr "file:/var/vmail/l/ laplanche_gan/Maildir/dovecot-quota" priv/quota/limit/storage 5242880 Does anyone know how to prevent Dovecot from adding that prefix and make it fetch the correct value from userdb ?

Password database - external verification
by Richard Hector 16 May '19

16 May '19

Hi all, I'm currently using a PostgreSQL database for my user/password db, directly from dovecot. The trouble with that is that I'm stuck with whatever hash algorithms dovecot supports - which IIRC means (a subset of?) what libc has been compiled with, which can be a bit restrictive. So I'd like to use an external tool, which would also let me integrate other applications (eg web apps). PAM seems to be most suited to sharing accounts with the OS, which isn't what I want.

Dovecot not connecting to OpenLDAP

Hi, We recently shutdown our old LDAP server and repointed our mail server (dovecot + postfix) to our new LDAP server and ever since we've been unable to fetch mail. Mail is getting delivered, but we just can't pop it. We're using Ubuntu 16.04, btw.

Likely 2 or 3. ldap_version = 3 # LDAP base. %variables can be used here. # For example: dc=mail, dc=example, dc=org base = ou=People,dc=cs,dc=lafayette,dc=edu # Dereference: never, searching, finding, always deref = never # Search scope: base, onelevel, subtree scope = subtree # User attributes are given in LDAP-name=dovecot-internal-name list.

Some variables can be used (see # http://wiki2.dovecot.org/Variables for full list): # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if user there's no domain user_filter = (&(objectClass=posixAccount)(uid=%u)) # Password checking attributes: # user: Virtual user name (user@domain), if you wish to change the # user-given username to something else # password: Password, may optionally start with {type}, eg. {crypt} # There are also other special fields which can be returned, see # http://wiki2.dovecot.org/PasswordDatabase/ExtraFields pass_attrs = uid=user,userPassword=password # If you wish to avoid two LDAP lookups (passdb + userdb), you can use # userdb prefetch instead of userdb ldap in dovecot.conf.

Setting up individual encrypted user keys using mail-crypt-plugin

Hi, I have setup up a simple mail server using the ISPMail tutorial and I'm trying to learn how to create email encryption at rest. I'm having a tough time understanding how to set this up... So say a user logins thru roundcube and they type in their password...so the password authenticates to the mysql database which is storing their encrypted private key?? And once they access that private key, how do they use that private key to unencrypt their mailbox? I'm a super noob at this, and I may … [View More]

LDA-based vacation responses bouncing
by micah anderson 14 May '19

14 May '19

I've got dovecot vacataion auto-responses working via sieve, but when the responses are sent, they are sent as if they are to be locally delivered, which causes them to bounce for domains that I am not local for. How can I get dovecot's sieve vacation response to check the domain is local or not? Here is an example of what happens: The LDA notices it needs to send a vacation response: 2019-05-14T10:50:47.827466-07:00 brant dovecot: lda(user(a)example.org)<14817><xL6LL/f/… [View More]2lzhOQAAh856Uw>: sieve: msgid=<20190514135045.012486@localhost>: sent vacation response to <someone(a)somewhere.org> but that response was sent via the postfix pipe through the dovecot lda transport... because that is local, and the domain it is sending to is not local, it bounces: 2019-05-14T10:50:47.923333-07:00 brant postfix/pipe[14821]: C998381539: to=<someone(a)somewhere.org>, relay=dovecot, delay=0.11, delays=0.04/0.01/0/0.06, dsn=5.1.1, status=bounced (user unknown) Postfix is set to do this: dovecot unix - n n - - pipe flags=DRhu user=mail argv=/usr/bin/spamc --connect-retries=1 -H -d 10.0.1.92 -s 10240000 -t 100 -u ${recipient} -e /usr/lib/dovecot/dovecot-lda -f ${sender} -d ${recipient} require ["fileinto", "vacation"]; vacation :days 2 :subject "Helllo" "Hi"; Here is my doveconf -n: # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.9.0-8-amd64 x86_64 Debian 9.8 auth_worker_max_count = 120 default_client_limit = 6144 default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k mail_location = mdbox:~/mdbox mail_plugins = expire quota zlib maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve zlib_save = gz zlib_save_level = 6 } protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { client_limit = 6144 unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 6144 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { unix_listener stats-writer { group = mail mode = 0660 } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes verbose_ssl = yes protocol lda { mail_plugins = expire quota trees zlib sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

To be specific * we mostly use/tested thunderbird client * we use maildrop for delivery * this is using imap, not pop3 * when a new email arrives, thunderbird renders the dir name in blue and appends a "(1)" (or more..). That's what we call 'see' * this happens only on 'subdirs', not the main … [View More]

doveadm sync issues (revised)

Hi, I'm experiencing serious issues using doveadm sync; mails are not replicating and/or mails are duplicating. I wanted to use this for migrating external mailboxes to my server (in order to overcome the time when some servers/clients still use the old server and some already my server, as described on <https://wiki2.dovecot.org/Tools/Doveadm/Sync>). Finally I was able to reproduce this with the 2.3 branch (cf. <https://dovecot.org/pipermail/dovecot/2019-April/115600.html>). I'm … [View More]sorry that I can only test the version 2.3.4.1, but according to the changelog I think this is still an issue with the latest version. I tried to find a few steps in order to replicate this easily: For testing purposes I simulate both the remote and local server on my Dovecot instance. I created remote(a)DOMAIN.TLD and local(a)DOMAIN.TLD accounts and both use mdbox and are empty. First, send two mails to remote(a)DOMAIL.TLD (Subjects: Test1 and Test2). Start backup remote IMAP account (remote(a)DOMAIN.TLD) to local account (local(a)DOMAIN.TLD) $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" backup -R -u local(a)DOMAIN.TLD imapc: Both mailboxes are in sync now (containing Test1 und Test2). Now send two messages to remote(a)DOMAIN.TLD (Subjects Test3 and Test4) and two messages to local(a)DOMAIN.TLD (Subjects Test5 and Test6). Run sync: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: See that syncing fails: remote(a)DOMAIN.TLD contains: Test1,2,3,4,5,6 (as expected) local(a)DOMAIN.TLD contains: Test1,2,5,6,4 (Test3 is missing here) When not using the "-R" parameter it seems to work. Running sync again: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: causes messages to duplicate: remote(a)DOMAIN.TLD contains: Test1,2,6,5,4,3,5,6,4,6,5,4,3,5,6 local(a)DOMAIN.TLD contains: Test1,2,5,4,6,4,5,6 (3 is still missing) This is independent of the "-R" parameter. I could also experience this issue when using one-way sync, however, the first one-way sync is still ok, but then messages start duplicating as for the two-way sync without "-R": $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -1 -u local(a)DOMAIN.TLD imapc: Hope you can replicate this, too, and finally fix the issue. -- Best regards, Sven Strickroth PGP key id F5A9D4C4 @ any key-server [View Less]

Dovecot not surviving OpenLDAP restart

Hi! Running Dovecot 2.2.36 and authenticating against an OpenLDAP 2.4.45 server. Now since some update of dovecot it will not be able to authenticate your logins after a restart of the LDAP service is restarted without a reboot of the dovecot server. Anything new here that I should be aware of? Best Regards Dag

UID to file?
by Carles Pina i Estany 09 May '19

09 May '19

Hello, In the past I was in a situation that given an email UID I wanted to know which file in the Maildir directory this UID was saved. I did a small parser for $HOME/Maildir/dovecot-uidlist where, if the file had: 1000 W1838 S1796 :1557351041.10447_1.example I would ask for the UID 1000 and would return :1557351041.10447_1.example (and I knew that it was in $HOME/Maildir/new) Is there any other way using dovecot tools to do the same, to avoid parsing an internal dovecot file?

Push Notification clarification (MessageNew w/o LMTP or LDA)
by Christian Balzer 09 May '19

Hello, Both the examples on the Push Notification wiki page and the XAPS plugin docs seem to suggest or state that LMTP/LDA is required. However IMAP IDLE notifications work without either of these (please no religious discussion of why Dovecot LMTP is the best thing since sliced bread and that everybody should use it). The LUA part of the push notification docs however states that events other than MessageNew are supported. So my question is, when not using LMTP/LDA and a LUA script and of … [View More]

dsync to backup to directory?
by Felipe Gasper 08 May '19

08 May '19

Hello, We have a hosting operation and are interested in offloading mail for some of our machines to a separate machine. We want the ability, though, to migrate accounts between the “offloaded” and “unified” configurations. Toward that end, is it possible to “merge” two different mail directories (either maildir or mdbox) via doveadm? “doveadm backup” looks like the closest match, but it doesn’t appear to accept an arbitrary directory as its synchronization source. Thank you! -Felipe Gasper Mississauga, Ontario

doveadm - mailbox to filesystem directory?
by Joaquin F 07 May '19

07 May '19

Is it possible to get the filesystem location (directory name) for a given mailbox? The closest I found was parsing the output of "doveadm -D mailbox create", but this only works if the mailbox doesn't exist yet and prone to failure if the debug output changes in future versions. Using "doveadm mailbox mutf7" helps, but there's some ASCII characters which are encoded. So far I've found "\" turns in to "\5c", "." into "\2e" and "/" to "\2f" and the separator to ".". But maybe there are others. … [View More]

Hi, In my LMTP config, I have lmtp_hdr_delivery_address = none.

http-lib test failures when building dovecot-2.3.5 and later in mock builder
by Tuomo Soini 07 May '19

07 May '19

There is random failure in test-http-payload when building rpm package from 2.3.6. I couldn't reproduce that in normal system but that happens something like every second try in mock chroot build envirnoment. Other tests don't have issues so it looks like test is not very reliable. Building 2.3.4 didn't yet have this issue. ./test-http-payload -D output attached. -- Tuomo Soini <tis(a)foobar.fi> Foobar Linux services +358 40 5240030 Foobar Oy <https://foobar.fi/>
