sievescript is not working
by ratatouille 12 Jul '18

12 Jul '18

Hello! I have a problem with a sieve-script which works for one domain but not for another one. Both domains are hostet on the same server running dovecot and postfix. This is the script that works: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)nimmini.de" :subject "absent" "Ich bin nicht da."; } This one does not, a vacation message is not sent: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)bitcorner.de" :subject "absent" "Ich bin nicht da."; } I don't know why. A sieve-test shows # sieve-test ./managesieve.sieve ./testfile -D sieve-test(andreas): Debug: sieve: Pigeonhole version 0.4.2 initializing sieve-test(andreas): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. debug: script binary ./managesieve.svbin is not up-to-date. debug: script `managesieve' from ./managesieve.sieve successfully compiled.

Sieve_default

I created a sieve_default to move any spam-tagged messages into the Junk mailbox automatically, but it doesn’t appear to be working (though the other imapsieve_mailbox… scripts are working).

Re: Authentication failure with OpenLDAP
by Anushka Bandara 12 Jul '18

12 Jul '18

Hi all, Thank you all for the help. The was with the ldap user attributes. I corrected it. Now I am having an error with dovecot. User can log into ldap but, system doesn't allow user to create user's directory in Maildir. Error is below, * Error: User initialization failed: Namespace '': mkdir(/home/users/"user"/Desktop/Maildir) failed: Permission denied (euid=1000(myuser) egid=5000(<unknown>) missing +w perm: /home, we're not in group 100(users), dir owned by 0:100 mode=0775)* How should I give the permission to overcome this error. This is a dovecot error. LDAP authentication is successful. And also, I don't know the default user whom is creating mail directories for mail users. I think the problem will be solved if I grant user the permission. But I don't know how to grant.

Storing Messages in the cloud
by Jerry 12 Jul '18

12 Jul '18

A colleague asked me if it was possible for Dovecot to store messages in the cloud. I have not heard of it being done and therefore assume it is not possible, but I thought I would ask regardless. I tried checking on the “One Drive” forum; however, I have not received any response back yet. Thanks! -- Jerry

Remove authentication penalty for webmailer
by Andreas Meyer 10 Jul '18

10 Jul '18

Hi all, I want to remove the authentication penalty for specific ip addresses (subnets if possible). I am using Dovecot 2.3.2 (582970113) and figured that this information: https://wiki2.dovecot.org/Authentication/Penalty > If the IP is in login_trusted_networks (e.g. webmail), skip any authentication penalties is not up to date. Instead this information is: https://wiki2.dovecot.org/Upgrading/2.3 --- START --- *Localhost Auth Penalty* Dovecot no longer disables auth penalty waits for clients connecting from localhost (or login_trusted_networks in general). The previous idea was that it would likely be a webmail that would have its own delays, but there are no guarantees about this. If the old behavior is still wanted, it's possible to do nowadays even more generically with e.g.: passdb { driver = passwd-file args = username_format=%{rip} /etc/dovecot/passdb } /etc/dovecot/passdb: 127.0.0.1:::::::nodelay=yes 192.168.10.124:::::::nodelay=yes --- STOP --- Adding the passdb section and creating a passdb file with the respective ip addresses does not have any effect though. Login failures through the webmailer are still being delayed. "dovecot -n" shows that the new passdb section is loaded: --- START --- passdb { args = username_format=%{rip} /etc/dovecot/passdb driver = passwd-file } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } --- STOP --- Changing orders does not make a difference. The passdb file contains these entries: --- START --- 127.0.0.1:::::::nodelay=yes 10.25.1.20:::::::nodelay=yes --- STOP --- The logfile shows the increased delay: --- START --- Jul 10 23:37:16 9fcdf83ee81e dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<xxx(a)yyy.zzz>, method=PLAIN, rip=10.25.1.20, lip=10.25.1.10, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bit s) Jul 10 23:37:25 9fcdf83ee81e dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=<xxx(a)yyy.zzz>, method=PLAIN, rip=10.25.1.20, lip=10.25.1.10, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bit s) --- STOP --- What am I missing?

Sieve-filter and default postmaster_address -> error?

I wanted to re-filter my inbox after adding some filters for my DMARC reports.

Dovecot on CentOS 7
by John Rowan 10 Jul '18

10 Jul '18

I guess I've been lucky. My Red Hat server I built in 2003 finally gave up the ghost yesterday. Fifteen years with almost zero problems running 7x24. Now I'm trying to build a basic server to host my e-mail using CentOS 7, Sendmail and Dovecot. Server is running great as are Sendmail and Dovecot but Dovecot only allows connections from the CentOS 127.0.0.1. I can telnet localhost pop3 and get a +OK Dovecot ready response. Trying to telnet from a different computer on same LAN times out. I've looked at my old Dovecot config files to see how I enabled LAN IP access but the configs have changed a lot since I last installed Dovecot. Googling hasn't helped. Anyone help with a sample config with LAN IPs permitted?

slow mailbox refreshes

Re: Question about password field in passwd-file

See https://wiki.dovecot.org/PasswordDatabase/ExtraFields > > > --- > Aki Tuomi > Dovecot oy Hi Aki, Thank you for your reply. I have two questions regarding this: 1. Is the “nopassword” attribute the same as specifying a null password field by itself ? The documentation at [1] seems to suggest that having a null password AND specifying “nopassword” will allow someone to authenticate with _no_ password: “nopasword: if you want to allow all passwords, use an empty password and this field.” Farther down, the page seems to indicate that the “nologin” attribute is what I am looking for: “nologin: User isn’t actually allowed to log in even if the password matches . . .” Or possibly “noauthenticate”: “noauthenticate: Do not perform any authentication . . ." 2. Is “nologin” functionally equivalent to specifying no password in the password field ? I am assuming that setting a null password (even without “nologin”), prevents login with ANY or NO password as a blank field would default to a {CRYPT} scheme and a call to crypt() cannot return a null string. As background to why I want to do this, I have a server with a basic Dovecot setup that provides SMTP SASL AUTH, IMAP and LMTP for Postfix. For the passdb and userdb, I use the same passwd-style file: /etc/dovecot/dovecot.conf userdb { driver = passwd-file args = /etc/dovecot/passwd } passdb { driver = passwd-file args = /etc/dovecot/passwd } I use usernames for SMTP SASL AUTH and IMAP that differ from either: user(a)example.com or user. So for one user, for example, I have: /etc/dovecot/passwd # SMTP SASL AUTH and IMAP user accounts and passwords user_account_1:{PLAIN}password: . . . # LMTP username/e-mail address user(a)example.com:: . . . :/var/mail/vhosts/example.com/user_account_1 So in the LMTP entry I specify no password between the colons to prevent someone trying to logon via IMAP using the LMTP username/e-mail address. Is this correct and: is there a better way to do this ? Thanks, - J Sources: [1] https://wiki.dovecot.org/PasswordDatabase/ExtraFields

The first doesn't change anything. The second auto-creates the folders after first login like I want, but after next login they are greyed out and no longer accessible. Is it possible to get rid of the "dbox-Mails"-folder? I want this because I don't like to have an unneeded deep folder structure. Or is there a good reason to let the "dbox-Mails" folder in my setup?

Question about password field in passwd-file
by J Doe 07 Jul '18

07 Jul '18

Hello, I have a question regarding the password field of the passwd-file [1]. According to the wiki, the password field assumes a {SCHEME} of CRYPT when the {SCHEME} is not prefixed to this field. So, a passwd-file like: user:password: . . . … is equivalent to: user:{CRYPT}password: . . . Does that mean an example passwd-file with NEITHER {SCHEME} or password, like: user(a)example.com:: . . . (note no scheme or password specified between colons) …means that the user(a)example.com user does not have any valid crypted password and therefore the user(a)example.com user cannot be authenticated ? For example, if I use doveadm to create a null CRYPT password: $ sudo doveadm pw -s CRYPT -p “” -u user(a)example.com … gives the result: {CRYPT}txR1JRq9140Qk … which differs from the example password field having NEITHER {SCHEME} or password, like: user(a)example.com:: . . . … so if I attempt to logon using a null password for user(a)example.com when nothing is specified in the password field for the passwd-file: /etc/dovecot/passwd user(a)example.com:: . . . $ sudo doveadm auth test user(a)example.com password: passdb: user(a)example.com auth failed … it is impossible to logon as user(a)example.com with ANY PASSWORD and/or a NULL password ? Thanks, - J Sources: [1] https://wiki2.dovecot.org/AuthDatabase/PasswdFile

Benchmarks with imaptest
by João Paulo Sacchetto Ribeiro Bastos 06 Jul '18

06 Jul '18

Hey guys, Has anybody ever used imaptest to benchmark *ONLY* reads? I'm trying to run a battery of tests in my new cluster and apparently no combination of parameters works, because fetch instruction doesn't run. Below is the command I'm using and its partial output imaptest/src/imaptest host=$SERVER_IP port=143 user=teste%d(a)example%d.com pass=$TEST_PASS users=10 domains=10 clients=100 - append=0 select=100 fetch=100 Logi Sele Fetc Logo 100% 100% 100% 100% 166 156 0 156 99/100 223 230 0 230 100/100 206 203 0 203 97/100 Can anybody help me understand why fetch doesn't work and how to fix this? Regards, -- João Paulo Bastos DevOps Engineer at Mav Tecnologia Belo Horizonte - Brazil +55 31 99279-7092

user/password Authentication via Joomla database
by Graham S. Jarvis 05 Jul '18

05 Jul '18

Hello, did anyone ever set up Authentication via lookups to a Joomla (mysql) database? What I'd like to do is lookup Joomla users (who are in specific/multiple groups) in the Joomla database and then fallback to /etc/passwd authentication to let system users authenticate. I'm running : # 2.2.35 (b1cb664): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.1-RELEASE-p10 amd64 Thanks in advance, -Graham-

v2.3.2 released
by Timo Sirainen 04 Jul '18

04 Jul '18

https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz.sig v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). Binary packages are already in https://repo.dovecot.org/ * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

Released Pigeonhole v0.5.2 for Dovecot v2.3.2.
by Stephan Bosch 03 Jul '18

03 Jul '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.2. You will need this release for Dovecot v2.3.2, because the previous v0.5.1 release will not work. No changes were performed since the release candidate. Much like version 0.4.24 for Dovecot v2.2, this release consists mostly of fixes that accumulated over the last few months. Beyond that, this release contains the new IMAP FILTER=SIEVE capability, which was also released earlier with 2.2.24 (with a few additional fixes). Changelog v0.5.2: + Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt. - The Sieve address test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

force-resync and replication
by Hanspeter Kunz 02 Jul '18

02 Jul '18

Hi list, I am using dovecot 2.2.27 (c0f36b0) on two servers with (dovecot) replication between them. I do not use dovecot-directors or -proxies. I just have a floating IP on the servers to do failover. I had the problem today that in one user's INBOX and one if his mailfolders got flooded with hundreds of thousands of duplicates. How this happened is another issue (of someone has an idea it would be more than welcome) for which I will start another thread. I remedied the situation by: 1. switching off dovecot on the standby-server to avoid duplicates getting replicated. 2. kicking the affected user from the master-server 3. running a doveadm force-resync on all his mailfolders (after removing the indices). Thereby I did get rid of the duplicates. (Note: doveadm deduplicate did not work because of index error) My question is now, what steps I need to take before enabling replication again (i.e. switching on the standby server), in order to avoid duplicates (if any) being replicated back to the master-server. Any hints are welcome. If you need more information I am happy to provide it, let me know. Best regards, Hp

permissions of newly created mailboxes only with dovecot-lda and posix acls
by Alexander 'Leo' Bergolth 01 Jul '18

01 Jul '18

Hi! I am experiencing troubles concerning the inheritance of the setgid bit if a new mailbox is created with dovecot-lda. If it is created with dovecot/imap, everything works fine. dovecot-lda is called from postfix like this: ---------- mailbox_command = /usr/local/sbin/postfix-lda.sh ---------- logger -p mail.info -t postfix-lda "H: $HOME, S: $SENDER, R: $RECIPIENT, U: $(umask), id: $(/bin/id); $@" dovecot-lda -f "$SENDER" -a "$RECIPIENT" -onamespace/inbox/location=maildir:~/Maildir:LAYOUT=fs:FULLDIRNAME=__MAILBOX__ ---------- If a mailbox is created with dovecot-lda (sieve), permissions look like that: $ ls -ld Maildir Maildir/2018-q3 Maildir/2018-q3/__MAILBOX__ drwxrws---+ 49 leo leo 4096 Jul 1 09:53 Maildir drwxrwx---+ 3 leo leo 24 Jul 1 09:40 Maildir/2018-q3 drwxrwx---+ 2 leo staff 6 Jul 1 09:40 Maildir/2018-q3/__MAILBOX__ -> The setguid bit of Maildir is not honored and dovecot complains: Jul 1 09:40:42 strike postfix-lda: H: /home/leo, S: testerl(a)strike.wu.ac.at, R: leo(a)strike.wu.ac.at, umask: 0077, id: uid=500(leo) gid=500(staff) groups=500(staff); Jul 1 09:40:42 strike dovecot: lda(leo): Error: fchown(/home/leo/Maildir/2018-q3/__MAILBOX__/cur, group=501(leo)) failed: Operation not permitted (egid=500(staff), group based on /home/leo/Maildir/2018-q3 - see http://wiki2.dovecot.org/Errors/ChgrpNoPerm) Jul 1 09:40:42 strike dovecot: lda(leo): Error: mkdir(/home/leo/Maildir/2018-q3/__MAILBOX__/cur) failed: Operation not permitted Jul 1 09:40:42 strike dovecot: lda(leo): Error: sieve: msgid=<20180701074042.1B1241CFB78(a)strike.wu.ac.at>: failed to store into mailbox '2018-q3': Internal error occurred.

Why is dovecot-lda behaving differently if Posix-ACLs are set on Maildir? Any why isn't dovecot imap affected? Any help would be greatly appreciated, I am actually clueless!

How to log a Sieve match in Dovecot debug_log
by Lukas 30 Jun '18

30 Jun '18

Hi everybody! I manage a mail server running Dovecot 2.2.21 with Pigeonhole 0.4.10. I successfully configured sieve and use it also to filter some spam messages. Here is one of the script I use to filter messages on the basis of prohibited words in message body. As you can see, the last command writes to the log the action of this script. -- the script begins ------------ require ["fileinto", "imap4flags", "editheader", "body", "vnd.dovecot.debug"]; if anyof ( body :text :contains "crypto", body :text :contains "sex", body :text :contains "viagra" ) { setflag "\\Seen"; addheader :last "X-Sieve-Filtered" "blocked words in message body"; fileinto "INBOX.Spam"; debug_log "Body contains blocked word: <the matching word>"; } -- the script ends -------------- MY QUESTION: is there a way to have also the result of the match in that log message? I mean, is it possible to have that "<the matching word>" substituted with the exact word that matched one of the conditions (more or less the same way it is possible using Exim's System Filter)? I googled and searched a lot Dovecot documentation but wasn't able to find a definite YES or NO to this question. Thanks a lot! Lukas

Auto configure email clients from Dovecot?
by Davide Marchi 30 Jun '18

30 Jun '18

Hi Friends, I'm using on Debian Jessie, Dovecot 1:2.2.13-12~deb8u3. I would like to know if is it possible to auto-configure the email client, for example Thunderbird or K-9 mail. Essentially I would like to know if is it possible to let dovecot instruct the mail client about how to auto-configure the email client. Actually my mail server parameters are not automatically taken from Thunderbird or K9-Mail. Is there a way to make this possible? Or am I on a wrong path? Many many thanks! Davide Italy

Looking into a solution for Caldav (and possibly carddav) support
by Nathan Coulson 30 Jun '18

30 Jun '18

We have an existing Dovecot/Postfix/Roundcube email solution, which I was hoping to add Caldav (and carddav?) support to, with the goal of 3rd party email clients being able to keep contacts and calendars in sync (as well as having the same information in roundcube) In doing research, I came across traces of it being considered for Dovecot at one time (https://www.dovecot.org/list/dovecot/2015-September/101996.html) and I was wondering where this went. Specifically, https://www.dovecot.org/list/dovecot/2015-September/101997.html seemed to hint that metadata support was a prerequisite for this (mainstream as of the email), and I was wondering if this meant there was potentially a solution built on top of this. Thank you -- Nathan Coulson

Sharing Mailbox between users using IMAP
by Luca Bertoncello 30 Jun '18

30 Jun '18

Hi list! I have an account (let's say info(a)mydomain.com) that should be read from more people. These people does NOT have an account on the server. Currently info(a)mydomain.com is a forward to their addresses, but of course this solution has a huge problem: if info@ receives spam that the server does not recognize, the server forwards spam... Now I want to solve this problem and I had the idea to change info@ from "forward" to "local account". Then, I can read the E-Mails via IMAP. Now the question: if I have 5-6 people accessing the account via IMAP, has Dovecot (2.2.13 from Debian repositories) problems? Is there other solution, if the users don't want to have an account on the server? Thanks a lot for your suggestion Luca Bertoncello (lucabert(a)lucabert.de)

FTS Solr errors using doveadm
by Ricardo Branco 30 Jun '18

30 Jun '18

doveadm: problem listing shared mailboxes using a wildcard
by Patrick Ben Koetter 27 Jun '18

27 Jun '18

I'm setting up a dovecot server with private and shared namespaces. My test setup has these mailboxes: # /bin/doveadm mailbox list -u fdl01(a)spike.test INBOX/sub01 shared shared/sammel01(a)spike.test shared/sammel02(a)spike.test INBOX In order to do some post-login scripting foo I'd like to get a list of shared mailboxes the user is currently subscribed to. The doveadm-mailbox man page says "It's also possible to use wildcards in the mailbox name." I'd like to use that feature to output only mailboxes from the shared namespace. However usind the wildcard character * doesn't output anything: # /bin/doveadm mailbox list -u fdl01(a)spike.test -s shared* # Am I doing something wrong? p@rick P.S.

use instance-name for syslog?
by A. Schulze 26 Jun '18

26 Jun '18

Hello, When running multiple instances of dovecot on the same host (or running multiple docker container), it is hard to distinguish logs from different processes: the syslog entries are all prefixed with the same identifier "dovecot" It is hardcoded here: https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c… Would it make sense to use the already implemented instance-name as syslog ident? How do others solve that problem? Andreas

sieve for systemusers
by ratatouille 25 Jun '18

25 Jun '18

Hello! I enabled LDA for systemusers bei adding mailbox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" to main.cf of postfix. I have done this because I want to use sieve for systemusers too, not only for virtual users. But the sievescripts do not work for those systemusers. What else needs to be done to get sieve to work for systemusers? Kind regards Andreas

upgrade 2.2 to 2.3, diffie-hellman, ssl_min_protocol
by tai74＠vfemail.net 25 Jun '18

25 Jun '18

hi sorry if question was asked already. Was reading https://wiki2.dovecot.org/Upgrading/2.3 first I'm confused on diffie hellman parameters file. I never set up ssl-parameters.dat before (should i have? do I have one that was automatically made for me by dovecot?) Do I need to make a fresh dh.pem? The upgrade doc tells how to convert ssl-parameters.dat but how to make a new one? other question is if I copy ssl_min_protocol from example config into my existing config is that enough? do experts on this list recommend any tweaks that increase client requirements more than dovecot developers are comfortable with but will ensure more secure protocol usage? ------------------------------------------------- ONLY AT VFEmail! - Use our Metadata Mitigator to keep your email out of the NSA's hands! $24.95 ONETIME Lifetime accounts with Privacy Features! 15GB disk!

Dovecot as transparent proxy for Exchange<->Dovecot<->Yahoo.com/Yandex.com with mail synchronization between servers !
by CpServiceSPb 25 Jun '18

25 Jun '18

We have Exchange as internal mail server, also we have gate where we plant to install Dovecot, also we have external mail at servers such as yahoo.com ort yandex.com. There are some mailboxes at Exchange, for example: user1(a)internal.ltd to user10(a)internal.ltd. There are some mailboxes at Ynadex.com, for example: personel1(a)external.com to personel10(a)external.com. 1. For messages flow: We need that Dovecot would act as at least transparent IMAP proxy for Exchange/Yandex and vise versa. For incoming messages - some messages comes to personel5(a)external.com located at Yandex.com, then Dovecot gets it from Yandex using IMAP IDLE, tnen stores it locally (where Dovecot is installed) to MySQL (using DBMail) or at least maildir format and after that sends it forward (using IMAP PUSH) to appropriate account user5(a)internal.ltd or triggers (signals) Fetchmail to sends forward it to specified Exchange acoount. And so on - for each external/interla pairs of accounts (Yandex.com/Exchange) . For outgoing messages - Exchange send out it using Exim4, Exim4 stores it locally (where Dovecot is installed) to MySQL (using DBMail) and then Exim4 sends it out to Yandex.com and in the same time Dovecot uploads this message to Yandex.com to "Sent" folder. And this messages is sent through Yandex.com. 2. For messages storage: When messages are deleted at Exchange, it are deleted from Dovecot (MySQL storage) and deleted from Yandex.com as well. Or when messages are deleted from Yandex.com, it are deleted from Dovecot (MySQL storage) and deleted from Exchange as well. Is it possible to set up Dovecot and may be some other soft (Fetchmail, imapsyncd and so on) to get point 1 working or point 1 and point 2 working ?

More and better logging
by Tom Sommer 25 Jun '18

25 Jun '18

In general I feel there is a lack of debug and "when things go wrong"-logging in Dovecot (information that should perhaps be provided with a verbose toggle). I was debugging problems with sasl user logins and a generic "SASL CRAM-MD5 authentication failed: Connection lost to authentication server" error in postfix, but nothing is logged in Dovecot when the error occurs. After extensive debugging I finally discovered auth-penalty and auth_penalty_to_secs after digging in the code. I suspect this to be the cause, but truly I have no way of confirming this, since no log is provided when this is triggered? - it would be nicer if events such as these were simply logged for better debugging and troubleshooting. Two cents :) Thanks -- Tom

Released Pigeonhole v0.5.2.rc1 for Dovecot v2.3.2.rc1.
by Stephan Bosch 24 Jun '18

24 Jun '18

Hello Dovecot users, Here is the Pigeonhole release candidate that goes with the Dovecot v2.3.2 release candidate. Much like version 0.4.24 for Dovecot v2.2, this release consists mostly of fixes that accumulated over the last few months. Beyond that, this release contains the new IMAP FILTER=SIEVE capability, which was also released earlier with 2.2.24 (with a few additional fixes). Changelog v0.5.2: + Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt. - The Sieve address test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.3/rc/dovecot-2.3-pigeonhole-0.5.2.… http://pigeonhole.dovecot.org/releases/2.3/rc/dovecot-2.3-pigeonhole-0.5.2.… Refer to http://pigeonhole.dovecot.org and the Dovecot wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

variable forwarding buglet
by Jan-Pieter Cornet 22 Jun '18

22 Jun '18

I wanted to forward information from the director to the backend dovecot (original login name), so I had the userdb on the director return a forward_ologin variable. However, when I tried to use that variable in the "password_key" query on the backend dovecot, ${forward_ologin} was expanded to UNSUPPORTED_VARIABLE_forward_ologin. After testing a bit and looking around in the source a bit, and turning on debugging logging, it appeared that the forwarded variables actually appear as "passdb/userdb extra fields". So in my case, the forwarded information is available as %{passdb:forward_ologin}. So, problem solved, but this is either an implementation bug, or a documentation bug, or oversight. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

TCP replication: high connection rate and looping in incomplete state
by tok 16 Jun '18

16 Jun '18

Hi, I am trying to establish TCP(s)-based replication between two FreeBSD 11.1 machines, both running Dovecot 2.2.35 (via pkg) with 10 virtual users and 1.2GB maildir. I followed the Wiki description (https://wiki2.dovecot.org/Replication) just skipped the SSH part. My resulting configurations are attached below. Problem: After reloading both Dovecot instances, a few seconds later they start to initiate connections in an absurdly high rate (30-50 new connections during 10 secs, closing old ones after 2-3 secs) and even after 1 hour they do not „calm down". E-mails are copied, but judging by size and file count, not completely (approx. 1GB and maybe 90% of files are getting synced). What is going on here? On the destination host (with empty storage before replication) I see "incremental - Waiting for dsync to finish“ in dsync-status, constantly flipping between handshake and waiting, for solely 4 out of 10 accounts. Replicator status says 0 requests and 10 total users. On the source host, replicator status says 4 queued full resyncs, 3 waiting failed and 10 total users. I already tried both tcps and tcp; activating debug log did not reveal any errors (e.g. SSL). Would be happy for any advice to track this down.

After logrotation Dovecot still writes to old log file
by Michael Heuberger 15 Jun '18

15 Jun '18

Hi there This is weird. On my latest Ubuntu server Dovecot seems to write to /var/log/dovecot.log.1 instead of a recently created /var/log/dovecot.log Here my logrotate config for Dovecot: /var/log/dovecot.log { su root syslog rotate 7 missingok copytruncate create 666 root syslog sharedscripts postrotate doveadm log reopen endscript } Doveadm should reopen it but no, still writes to old log file. Not sure, maybe it's someone else, not dovecot, writing to the log file? And here the versions: # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) # OS: Linux 4.14.49-rh65-20180612025235.xenU.x86_64 x86_64 Ubuntu 18.04 LTS How can we investigate best?

Race condition when setting flags (\Deleted) + expunge quickly, leaving mails not deleted
by Tomas Forsman 12 Jun '18

12 Jun '18

Hello. I seem to have found a race condition, when setting flags on multiple emails rapidly. 5 commands including login to reproduce. Problem found using mutt in real world usage. Seems to happen both with UID STORE 1:3 and UID STORE 1,2,3 .. I have tried with the following packages, with a minimized config in a throwaway vm: https://packages.debian.org/stretch/dovecot-core Package: dovecot-core (1:2.2.27-3+deb9u2) https://packages.debian.org/stretch-backports/dovecot-core Package: dovecot-core (1:2.2.34-2~bpo9+1) Also tested pristine: https://dovecot.org/releases/2.3/dovecot-2.3.0.1.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.34.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.35.tar.gz .. built on Debian9 with: # apt-get build-dep dovecot-core # bash configure --prefix=/scratch/dovecot-test Tried with both mailbox over NFS (backed by ext4), and also mailbox on ext4. On my test systems, I am only able to reproduce it with mbox_lazy_writes=no, but with production settings on a Ubuntu 14.04 with 1:2.2.9-1ubuntu2.4 that has mbox_lazy_writes=yes it is still reproducable with mutt. I have found two different ways to reproduce it with netcat + cut'n'paste, below is done with 2.2.34/35. All servers are VMs in Ganeti/kvm clusters (Debian hosts in one cluster&organization, Ubuntu host in another cluster&organization). Debian minimized config: > doveconf -n # 2.2.34 (874deae): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.22 (22940fb7) # OS: Linux 4.9.0-6-amd64 x86_64 Debian 9.4 # Hostname: mail2-vm.cs.umu.se auth_mechanisms = plain login auth_verbose = yes debug_log_path = syslog info_log_path = syslog mail_location = mbox:~/Mail:INBOX=/var/mail/%u mail_privileged_group = mail mbox_lazy_writes = no namespace inbox { inbox = yes location = prefix = } passdb { driver = pam } protocols = imap service auth { client_limit = 2500 unix_listener auth-client { group = postfix mode = 0660 } } service imap-login { inet_listener imap { port = 143 } } service imap { executable = imap } ssl = no syslog_facility = local1 userdb { driver = passwd } Attached is a mailbox that can be used to reproduce the problem, called "error-box", anonymized with mbox-anonymize.pl. It was created by sending test messages with mutt 1.7.2 through Dovecot/Postfix/Amavis. **** Method 1, with IDLE: Setup a local account, MY-USER / MY-PASSWORD (replace below). > mkdir Mail > cp error-box Mail/error1 > nc -v localhost 143 Paste the following 3 lines in a go: a0000 LOGIN "MY-USER" "MY-PASSWORD" a0010 SELECT "error1" a0020 IDLE then wait a second.. then paste the following 3 in a go: DONE a0030 UID STORE 1:3 +FLAGS (\Deleted) a0040 EXPUNGE Notice that the results from UID STORE + EXPUNGE gives: * 2 FETCH (UID 2 FLAGS (\Recent)) * 3 FETCH (UID 3 FLAGS (\Recent)) * 1 EXPUNGE * 3 RECENT a0030 OK Store completed (0.004 + 0.000 + 0.003 secs). a0040 OK Expunge completed (0.004 + 0.000 + 0.003 secs). Verify what's left in the mailbox with: a0050 UID FETCH 1:4 FLAGS * 1 FETCH (UID 2 FLAGS (\Recent)) * 2 FETCH (UID 3 FLAGS (\Recent)) * 3 FETCH (UID 4 FLAGS (\Recent)) a0050 OK Fetch completed (0.001 + 0.000 secs). Since 1 to 3 should be \Deleted and then EXPUNGEd, we should only have UID 4 left, not uid 2-4 without Deleted flag. Try same again, but with 1 inserted delay (use a new mailbox name for every test, otherwise UID numbering will vary, indexes etc): > cp error-box Mail/error2 > nc -v localhost 143 Paste the following 3 lines in a go: a0000 LOGIN "MY-USER" "MY-PASSWORD" a0010 SELECT "error2" a0020 IDLE then wait a second.. then paste 1 line: DONE then [newly introduced] wait a second.. then paste 2 lines: a0030 UID STORE 1:3 +FLAGS (\Deleted) a0040 EXPUNGE Notice that the results from UID STORE + EXPUNGE gives: * 1 FETCH (UID 1 FLAGS (\Deleted \Recent)) * 2 FETCH (UID 2 FLAGS (\Deleted \Recent)) * 3 FETCH (UID 3 FLAGS (\Deleted \Recent)) a0030 OK Store completed (0.003 + 0.000 + 0.002 secs). * 3 EXPUNGE * 2 EXPUNGE * 1 EXPUNGE * 1 RECENT a0040 OK Expunge completed (0.003 + 0.000 + 0.002 secs). Verify what's left in the mailbox with: a0050 UID FETCH 1:4 FLAGS * 1 FETCH (UID 4 FLAGS (\Recent)) a0050 OK Fetch completed (0.001 + 0.000 secs). So if I wait some between DONE and UID STORE, it seems to be ok.

Re: 2.3.1 Replication is throwing scary errors
by Reuben Farrelly 08 Jun '18

Hi Andy, Funny you say that - I've been testing this very problem for some time today to narrow down the commits where I think the problem started occurring. So far I have been able to roll forward to commit from git: 74ef8506dcb946acc42722683e49fdcb964eed19 >> "doveadm: Unref header search context after use" . So far I have been running on that code for a few hours and I'm not yet seeing the problem, which indicates the issue is probably subsequent to this. I'm of the view that the problem started occurring somewhere between that commit above on 6 March and the final 2.3.1 release on 27 March. There are a lot of changes between those two dates, and testing to narrow down to one specific commit is extremely time consuming. It would be really helpful if even one of the Dovecot developers could comment on this and give us some direction (or candidate commits to investigate) or just let us know if the root cause has been found. This bug is a showstopper and has stopped me tracking master-2.3 for over 3 months now, as I can't test later builds or even upgrade to the 2.3.1 release while replication is so broken.

sieve, pigeonhole; reject message
by dovecot-user 08 Jun '18

08 Jun '18

Hello everybody. I use the version of dovecot 2.3.0.1 and postfix 3.3.0 on my test computer. Postfix pass incoming messages to Dovecot via the LMTP protocol. I want to understand how to fine tune the "reject" action in sieve-scripts. The task: in my installation I use the translation of a set of aliases into the (hidden) target email address inside postfix (postfix directives: canonical_classes = envelope_recipient; canonical_maps = hash://etc/postfix/canonical), so in dovecot the mails fall into one mailbox; However, the original headers (for example, the alias of the recipient) can be extracted with sieve scripts (the "Received" header). In my case, when I use the "reject" action in the sieve script, dovecot generates a message to the sender with the text: "Your message to <hidden(a)domain.tld> was automatically rejected ..", but this behavior opens the address to the sender of what is hidden behind the alias. Is it possible to redefine the text of the reject message using the extracting values from the "Received" header so that the email address hidden behind the alias does not appear there? Or some other way to customize the reject-message? Thank you.

Shared mailboxes, index files and 'per-user-seen' flags
by Thomas Robers 07 Jun '18

07 Jun '18

Hello, i have a dovecot server version 2.3.1 under CentOS 6.9 and we're using shared mailboxes with index files shared. With this configuration I can see a lot of error messages like: Jun 6 13:20:31 mail dovecot: Error: imap(userA(a)tutech.de)<4513> <onjjWPdtDuLAqG3R>: /export/home/imap/userA(a)tutech.de/shared /userB(a)tutech.de/folder/dovecot.index.pvt view is inconsistent In 10-mail.conf the location setting is: location = maildir:%%h/Maildir:INDEXPVT=%h/shared/%%u I thought setting the index files to "not shared" might help to get rid of the errors, so I changed the setting to: location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:INDEXPVT=%h /shared/%%u like it's mentioned in the Dovecot wiki. But that doesn't work as I expected, because the 'per-user-seen' flags do not work correctly anymore, i think. If UserA, who has UserB as shared mailbox, changes the seen flags of UserBs INBOX, UserBs seen flags are also changed. The other way, if UserB changes seen flags in his INBOX they are not changed in the shared view of UserA. Is this the supposed way to work or do i have an error in the configuration? Any help is appreciated. Thanks, Thomas.

Header DATE field not returned when placed after MIME section
by Xavier Guerin 06 Jun '18

06 Jun '18

Hello, I am using Dovecot 2.2.34p0 on OpenBSD 6.3 stable. I am writting an application using the vmime (http://www.vmime.org) library (x-ref issue: https://github.com/kisli/vmime/issues/199) I noticed through testing over my own e-mail server that in some situations the DATE field is not returned upon ENVELOPE or HEADER.FIELDS request. The e-mails at fault happen to have the DATE field at the very end of the header, after the MIME section. Example 1: Delivered-To: Received: Return-Path: Delivered-To: DKIM-Signature: From: To: Message-ID: Subject: MIME-Version: 1.0 Content-Type: text/html;charset=UTF-8 Content-Transfer-Encoding: 7bit Date: Fri, 01 Jun 2018 17:44:44 -0400 Example 2: Return-Path: Delivered-To: Received: Delivered-To: DKIM-Signature: From: Reply-To: To: Subject: MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_338_1573405959.1527768044781" X-Mailer: EMail_2.0 Date: Fri, 01 Jun 2018 17:36:01 -0400 Thanks in advance for the insight,

offtopic: Solr compatible IMAP client
by Andy Smith 04 Jun '18

04 Jun '18

Hi, not sure if I'm allowed to go this off topic on here, sorry if not! I've just installed Solr FTS for Dovecot and its great, as is Dovecot! ;) It works perfectly for fast searches using Roundcube, but can anyone suggest any Windows and/or Linux mail clients that work well with IMAP searches rather than doing their own searches on local copies of mails? I've had a look at Thunderbird and you can use IMAP search, buy you have to manually select it from an advanced search dialogue and it seems you cannot make this the default behaviour. I also tried OperaMail but it doesn't appear to work at all (only header is searchable without downloading local copies). I'm pretty sure Outlook will only use its own search engine on its local copy of data. thanks a lot, Andy. PS this guide was really helpful for setting up Solr FTS with a recent release of Solr (I'm using 6.5), might be worth including a link somewhere on the Dovecot wiki?: http://mor-pah.net/2016/08/15/dovecot-2-2-with-solr-6-or-5

Struggling with sieve, fileinto and variables.
by Barry Pearce 31 May '18

31 May '18

Hi, Im on Manjaro linux fully up to date running dovecot 2.3.1-2 pigeonhole 0.5.1-2 All is running well except I am having problems with fileinto - it refuses to use variables, and mailboxexists is also failing for me. Im just dealing with plus addressing - should be simple but the behaviour Im experiencing isnt right. require ["variables", "envelope", "fileinto", "subaddress", "mailbox"]; if envelope :matches :detail "to" "*" { set :lower "name" "${1}"; } fileinto :create "folder3"; This works, but changing the last line to: fileinto :create "${name}"; fails and files into inbox. As does: fileinto :create "${1}"; It makes no difference if the fileinto is placed inside the if statement or otherwise. Using sieve-test suggests the basic script it should work and traces show the right action. On a related matter the script Im actually trying to get to work is: require ["variables", "envelope", "fileinto", "subaddress", "mailbox"]; if envelope :matches :detail "to" "*" { set :lower "name" "${1}"; } if mailboxexists "${name}" { fileinto :create "${name}"; } But fails and files in the inbox. Modifying the script to: require ["variables", "envelope", "fileinto", "subaddress", "mailbox"]; if envelope :matches :detail "to" "*" { set :lower "name" "${1}"; } if mailboxexists "${name}" { fileinto :create "folder7"; } else { fileinto :create "folder8"; } Files into folder8. So the mailboxexists is failing. ## Started executing script 'plus-addressing' 3: envelope test 3: starting `:matches' match with `i;ascii-casemap' comparator: 3: getting `to' part from message envelope 3: extracting `detail' part from address <test+folder4(a)test.net> 3: matching value `folder4' 3: with key `*' => 1 3: finishing match with result: matched 3: jump if result is false 3: not jumping 4: set command 7: modify :lower "folder4" => "folder4" 7: assign `name' [0] = "folder4" 7: mailboxexists test 7: mailbox `folder4' cannot be opened 7: some mailboxes are unavailable 7: jump if result is false 7: jumping to line 9 10: fileinto action 10: store message in mailbox `folder8' ## Finished executing script 'plus-addressing' Here folder4 actually does exist - so the sieve-test confirms that issue. Im at a loss as to whats going on. Im particularly perplexed by the difference in behaviour between sieve-test and the result under the live server. Any ideas?

Setting up postfix/dovecot on a clean FreeBSD cloud server, and have discovered a strange problem resulting from the interaction of Mac OS X Mail and dovecot (using the Maildir file structure). Essentially, under very specific circumstances, Mail somehow tells dovecot that a new incoming message is trash, dovecot marks it as such, and the message effectively vanishes. The specific circumstance is as follows: 1. A message is sent to a server running postfix. It is placed in the Maildir mail structure in the “new” directory. 2. OS X Mail is used to retrieve mail via IMAP, and dovecot transfers the message from “new” to “cur”. 3. OS X Mail has a rule that seeks to transfer an incoming message to a subfolder if the message sender belongs to a group created in the Contacts app (IOW the sender is matched against an OS-internal contacts database). 4. IF the sender is the user, AND the user is in the group against which the rule is compared, the message is marked as trash (suffix “T”) and is never loaded into the mail client, either in the inbox or in the trash folder. For all intents and purposes, it disappears. The connection log shows the following line: "WROTE May 30 23:38:11.960 [kCFStreamSocketSecurityLevelTLSv1_2] -- host:cloud.helical.com -- port:993 -- socket:0x6080004b6c80 -- thread:0x604000678e40 12.3 UID STORE 125 +FLAGS.SILENT (\Deleted)” which appears to be the client instructing dovecot to mark the message as deleted. I have the log files from the connection on both sides, and the console log from the Mac, but can’t understand 1. how Mail decides that the message should be deleted, and 2. why Mail “loses” the message (doesn’t appear in the Trash mailbox or anywhere else). _____ Robb Aley Allan

imapsieve: mailbox Trash: FLAG event
by Peter Schiffer 30 May '18

30 May '18

Hi all, after upgrade from Dovecot 2.2 to 2.3 I started to see that emails from Trash folder are automatically deleted after ~7 days. Email clients are not configured to automatically expunge or empty trash on log out (I see this behavior for multiple mailboxes, with different clients). With mail_debug enabled, I see this log message for every email that gets deleted from Trash: May 29 08:02:17 hostname dovecot: imap(some@mail)<7725><xxb6+VFtL+JT0CE 8>: Debug: imapsieve: mailbox Trash: FLAG event (changed flags: \Deleted) I have Dovecot 2.3.1 (8e2f634) and Pigeonhole 0.5.1 for sieve. My configuration can be found here: https://github.com/pschiffe/mailcow-dockerized/tree/master/data/conf/dovecot There is enabled support for sieve config in sql, but all sieve tables are empty, and there are no sieve filters for Trash flagging. Do you know how to find the source of that Trash flag event? I need to disable it or to configure it so it deletes emails at least couple of months old. Thanks all, peter

Second rule isn't apply when first rule matches
by daniel_1983＠protonmail.com 30 May '18

30 May '18

Dear list, I want to define two concurrent rules : 1. I want to flag an e-mail containing the word "cloud" in the body 2. I want to move mail sent explicitly to me (as opposed to mail sent to an alias I am part of) going to "INOBX.I must answere this" If I put rule (1) first, everything works as expected. If put rule (2) first, only that rule applies. Here's a small test case you should be able to reproduce on your setup. Let's work on this fake test e-mail : $ cat testmail.eml Date: Mon, 28 May 2018 12:41:53 +0100 From: friend(a)otherdomain.tld To: me(a)mydomain.tld Subject: dur dur la vie mon frère, le cloud c'est le top du top Here's the first, broken version of the script $ cat test.sieve require ["body","fileinto","imap4flags","vacation"]; # rule:[Mail about me] if anyof (header :contains "to" "me(a)mydomain.tld", body :text :contains "ahmed") { fileinto "INBOX.I must answere this"; } # rule:[Mail about the Cloud] if body :text :contains "cloud" { addflag "\\Flagged"; } Let's test it out, the two rules should be applied : $ sieve-test test.sieve testmail.eml Performed actions: * store message in folder: INBOX.I must answere Implicit keep: (none) sieve-test(root): Info: final result: success $ Notice that the last rule isn't applied although it matches. Now we invert the order of the rules and apply the script on the same test e-mail : $ cat test.sieve require ["body","fileinto","imap4flags","vacation"]; # rule:[Mail about the Cloud] if body :text :contains "cloud" { addflag "\\Flagged"; } # rule:[Mail about me] if anyof (header :contains "to" "me(a)mydomain.tld", body :text :contains "ahmed") { fileinto "INBOX.I must answere this"; } Running the test again : $ sieve-test test.sieve testmail.eml Performed actions: * store message in folder: INBOX.I must answere + add IMAP flags: \flagged Implicit keep: (none) sieve-test(root): Info: final result: success $ The IMAP flag was set ! Any ideas ?

Problem in Pigeonhole sievec
by Thorsten Hater 30 May '18

30 May '18

Dear all, I stumbled upon the following behaviour of Pigeonhole, which I consider to be problematic. A user deployed a Sieve script similar to the following snippet if not anyof (address :is ["from","cc"] ["...", ..., "...@... GARBAGE", ...] { fileinto "inbox.Trash"; stop; } Note the extra line break before GARBAGE. This script is obviously broken, but gets accepted by sievec and only fails later, at runtime with line X: error: found stray carriage-return (CR) character in quoted string started at line X. So, the question is whether line breaks in strings are allowed in general and the runtime error is unavoidable, or should sievec return an error? Best regards, Thorsten

OAUTH2 + proxying [host=??]
by DevOps 30 May '18

30 May '18

All, We currently use a proxy configuration with an sql query to authenticate and discover which backend server an address belongs to and proxy the connection to that host to authenticate and retrieve mail. We are looking to move to OAUTH2 for authentication and am just trying to figure how how to get that extra host information as part of the passdb query when using this mechanism. Looking at doco if we were running a director setup (which we are not) that process seems to be able to poke that info into response but is there any other way of doing this ? Should we be getting or can we get OAUTH2 to return extra fields and configure the pass_attrs to be host=%{passdb:proxyToHost} or something like that ? Any information/thoughts would be good to hear. rgds Matt

Bug: Dovecot index loosing sync with FTS despite "fts_autoindex = yes"
by kfx 29 May '18

29 May '18

dovecot 2.2.34 solr 7.2 I only see new messages after typing on the server "doveadm fts rescan -u username" though I've followed the wiki and added "fts_autoindex = yes" in 90-plugin.conf . Subsequent search for the same pattern always gives the same result, ignoring new emails with that particular pattern. Solr is working correctly and the correct search results comes immediately (whatever the searched word) after a "doveadm fts rescan" # doveconf | grep fts mail_plugins = " quota stats fts fts_solr" fts = solr fts_autoindex = yes fts_solr = url=http://localhost:8983/solr/dovecot/ [POP] mail_plugins = " quota stats fts fts_solr sieve virtual" [IMAP] mail_plugins = " quota stats fts fts_solr imap_quota virtual imap_stats"

Search problem
by Federico Bartolucci 28 May '18

28 May '18

Hello, when doing a simple search through the lucene indexes in some mailboxes (with actually many subfolders) the search terminates after a few seconds with no result and the dovecot log shows this error: Fatal: master: service(imap): child 15433 killed with signal 6 (core not dumped) Any clue about the reasons? the lucene indexes have been already rebuilt and look OK.

You can use value '2' for enabling encryption. DO NOT USE 1. Also I tried the SQL based thing, and if you had EMPTY mail_crypt_private_password, try these to change the password.

lda / postfix / dovecot -- bounced messages not working
by Scott Ruckh 25 May '18

25 May '18

I saw another thread about this topic, but I did not understand the solution. . . I recently discovered my bounced messages were not getting delivered. Obviously since I was not getting any messages, I thought everything was fine. Anyway, my maillog has entries similar to below for bounced messages: Mar 29 10:48:09 firewall postfix/pipe[9089]: 19565807: to=<myuser(a)my.domain>, relay=dovecot, delay=0.11, delays=0.02/0.01/0/0.08, dsn=5.3.0, status=bounced (command line usage error. Command output: lda: Fatal: Invalid -f parameter: Missing domain ) In the previous thread discussing this issue it mentioned that this was a dovecot error and possibly due to a dovecot 2.3.0 upgrade. I am running dovecot-2.3.0-1.1 on a CentOS 7 server. The solution from the other thread simply stated that the original poster is instead using lmtp instead of lda, or at least that it was I got from the thread. If using lmtp instead of lda is the correct solution, could I get an example of what configuration changes need to be made to make that happen? Otherwise, has anyone else seen this error and know the solution to make it work. My current dovecot configuration for postfix (master.cf) is using the de-facto standard from many web docs: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient} This is the same configuration that was originally setup and has worked for years; until the bounced message problem was recently discovered. If anyone has seen this error and knows the solution, I would appreciate the help. Thank You. Scott

last login tracking error

Hello, I'm running dovecot 2.2 and trying to do last login tracking. I am using a MySQL database. When a user logs in I get this in the log: 2018-04-07 16:55:14 imap(user(a)example.com)<54415><BmevY0hpMN5/AAAB>: Error: last_login_dict: Failed to write value for user user(a)example.com: dict-server returned failure: sql dict: commit failed: Field 'name' doesn't have a default value (reply took 0.018 secs (0.000 in dict wait, 0.009 in other ioloops, 0.001 in locks, async-id reply 0.000 secs ago, started on dict-server 0.006 secs ago, took 0.006 secs)) Here's an excerpt from my dovecot-dict-sql.conf.ext file: map { pattern = shared/last-login/$user table = accounts value_field = last_login value_type = uint fields { username = $user } } The username does have a value. Can anyone see what I've got wrong? Thanks.
