Thanks for 2.3.5 - it fixed a lot of stuff :) I see this Panic in my Director logs now, randomly and rarely: Mar 07 11:01:29 pop3-login: Panic: file iostream-openssl.c: line 586 (openssl_iostream_handle_error): assertion failed: (errno != 0) Mar 07 11:01:29 auth: Warning: auth client 13625 disconnected with 19 pending requests: EOF Mar 07 11:01:29 pop3-login: Fatal: master: service(pop3-login): child 13625 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set /proc/sys/fs/suid_dumpable to 2) Hoping the above is enough to debug -- Tom

Probleme with replication and shared mailbox
by Laurent BRAULT (OSILOG) 06 Mar '19

06 Mar '19

Hi Folks ! I finaly resolve my problem ! 😊 First of all I had to modify namespaces : ####################################################### namespace inbox { inbox = yes location = mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = INBOX/ separator = / subscriptions = yes type = private } namespace partage { list = children location = maildir:/mnt/mail/vmail/%%d/%%n:INDEXPVT=/mnt/mail/vmail/%d/%n/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } ####################################################### Also change the « replication_dsync_parameters » in aim to syncronize only the Private namespace : ==> replication_dsync_parameters = -d -n inbox -l 30 -U I change the sharing command from « acl set » to « acl add » AND THE MOST IMPORTANT ==> RUN THE COMMAND ON THE 2 SERVER because of active/active réplication… ==> doveadm acl add -u user2(a)exemple.fr INBOX user=user1(a)exemple.fr admin create delete expunge insert lookup post read write write-deleted write-seen Hope this may help if someone is faced to the same problem Best regards Laurent

“Message cannot be displayed because of the way it is formatted” iOS
by James Brown 06 Mar '19

06 Mar '19

Have updated our mail server and are now running Dovecot 2.3.4. Things are mostly working OK, but occasionally I have users on latest iOS getting this message: “this message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. multipart/alternative” The email seems to open OK on the macOS version of Mail.app. Also getting “Loading...” displayed in body section of the app with content never displayed. Most emails are fine, but just get this strange ones occasionally. Our previous mail server was much older, with older version of Dovecot, etc. This server never used to have these issues. Just wondering if anyone has any ideas or suggestions? Can’t see anything in the logs. Thanks, James.

getrandom() before forking daemon is blocking init system
by Axel Burri 05 Mar '19

05 Mar '19

Hello When booting from a slow machine, I can observe dovecot blocking the whole boot process. I traced it down to the getrandom() system call in lib/randgen.c, which blocks until the random number generator is initialized (dmesg "random: crng init done"). This can take up to three minutes (!) on my machine, as there is not much entropy available (no hardware RNG, network VPN is also waiting for random). Unfortunately dovecot calls getrandom() before forking a daemon, which as a consequence blocks the whole init process (OpenRC on Gentoo Linux). I believe this behavior has changed in kernel 4.14: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… Quoting getrandom(2): "If the urandom source has not yet been initialized, then getrandom() will block, unless GRND_NONBLOCK is specified in flags." Dovecot: 2.3.4.1 (f79e8e7e4) Linux: 4.19.26-gentoo #2 SMP Thu Feb 28 20:30:23 CET 2019 x86_64 AMD G-T40E Processor AuthenticAMD GNU/Linux Regards, Axel

Pigeonhole v0.5.5 released
by Aki Tuomi 05 Mar '19

05 Mar '19

Hi! We are happy to release pigeonhole v0.5.5 for dovecot v2.3.5. Please find sources at https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.5.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.5.ta… (Please note that the signing key has been changed for 0.5.5, see https://pigeonhole.dovecot.org/download.html for details.) You can find precompiled binaries at https://repo.dovecot.org/ NEWS: + IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which causes messages discarded by an IMAPSieve script to be expunged immediately, rather than only being marked as "\Deleted" (which is still the default behavior). - IMAPSieve: Fix panic crash occurring when a COPY command copies messages from a virtual mailbox where the source messages originate from more than a single real mailbox. - imap4flags extension: Fix deleting all keywords. When the action resulted in all keywords being removed, no changes were actually applied. - variables extension: Fix truncation of UTF-8 variable content. The maximum size of Sieve variables was enforced by truncating the variable string content bluntly at the limit, but this does not consider UTF-8 code point boundaries. This resulted in broken UTF-8 strings. This problem also surfaced for variable modifiers, such as the ":encodeurl" modifier provided by the Sieve "enotify" extension. In that case, the resulting URI escaping could also be truncated inappropriately. - IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that modify the message, stored the message a second time, rather than replacing the originally stored unmodified message. - Fix segmentation fault occurring when both the sieve_extprograms plugin (for the Sieve interpreter) and the imap_filter_sieve plugin (for IMAP) are loaded at the same time. A symbol was defined by both plugins, causing a clash when both were loaded. --- Aki Tuomi Open-Xchange Oy

two lots of dovecot files
by mick crane 04 Mar '19

04 Mar '19

hello is debian buster I have 2 sets of dovecot files, I don't know why. one in /etc/dovecot and one in /usr/share/dovecot they are not links they are actual files. if I rename /etc/dovecot and restart service then I get connection refused when use roundcube. Some time ago my roundcube installation stopped working properly for the web configuration options. Should I have these 2 directories or just want the one ? If want only one it's likely then that I configure wrong file with same name when I thought my ssl certificate has expired. Is OK to delete /etc/dovecot and check configuration in /usr/share/dovecot ? -- Key ID C7D6E24C

Pigeonhome Sieve: check existence of a folder?
by AvV 03 Mar '19

03 Mar '19

Dear All, Thanks ofr the great job so far. I have crawled the doc & web, and did not find oh to check for the presence of a folder ina a mailbox? I know about "fileinto :create" of course, but the purpose is slightly different: I want to automate the move into a folder based on some rules but *only if* an associated folder is present (which name is based on the rule), otherwise I will do a form of catch-all. Example: - INBOX +- abc +- def - Rule detects "aaa" in someheader field: folder "aaa" not present" -> continue; - Rule detect "def" in some header field: "def exists" -> fileinto "def" ; stop; Any help appreciated. Cheers, A/

Unexpected behavior with sieve_vacation_to_header_ignore_envelope = yes
by Matthias Petermann 03 Mar '19

03 Mar '19

Hello, we face an issue with the vacation extension of pigeonhole. Our upstream mail server (from which we pull our E-Mails with POP3) uses SPF and performs a SRS re-write of the Return Path. Once the mail is processed via our local postfix, it is delivered via dovecot deliver (using the lda). When the recipient has a vacation rule enabled in sieve, the out-of-office note cannot be sent, as pigeonhole tries to use the Return-Path (which is not accepted as sender by the mail server). We are using the following dovecot / pigeonhole versions: dovecot-2.3.2.1 dovecot-pigeonhole-0.5.2 As of my understanding, the problem was addressed in pigeonhole version v0.4.21 by introducing the sieve_vacation_to_header_ignore_envelope setting. Anyway - even when this is set to "yes" pigeonhole still uses the Return-Path instead of the "From:" header which I had expected: Feb 27 13:22:26 mail dovecot: lda(customer)<48383><3o+yOQGBdlz/vAAAZU03Dg>: Error: sieve: msgid=<e081d2ba-21d5-c32b-3750-69fe0c8a76d2(a)petermann-it.de>: failed to send vacation response to SRS0=gwGXg6ad=RC=petermann-it.de=matthias(a)example.com: <Sendmail program returned error> (temporary error) Are my expectations wrong or did I miss some precondition?

I have an imap and pop3 for the same account. When I delete a message from imap and then fetch the mail from the pop3 account, it retrieves the deleted message. I am using thunderbird for the MTA. Does anyone know why it happens? It could be a timing issue.

Dovecot Logging and Shell Script Hang
by Asai 28 Feb '19

28 Feb '19

Greetings, We have a PHP based shell script that runs a doveadm backup routine. This script was running just fine, and then we turned on more logging for Dovecot (enabled the mail_log plugin). For some reason, once this was done, the shell script would run for a few minutes and then hang, as it added more log messages to the dsync STDOUT. Once the mail_log plugin was disabled, it ran without hanging. Is there any way to run doveadm and temporarily suspend the mail_log plugin? Or is there a better way to do this? Thanks for the insights. Asai

performance issue with UID SEARCH
by Ben Burke 27 Feb '19

27 Feb '19

Hi, I'm running dovecot 2.2.x and I'm having an issue where I see many dovecot processes use all the available IO on a server. According to iotop the worst offenders seem to be in this state (NOTE: I swapped in phony username & IP info): dovecot/imap [someusername 123.456.789.012 UID SEARCH] The server in question is running with Maildirs on top of an XFS filesystem. Is there anything I can do to optimize "UID SEARCH" or find out why it's being a problem? I've read https://wiki2.dovecot.org/PerformanceTuning and the linked pages. By "being a problem" I mean iostat -xmt 1 /dev/diskdevice shows 100% utilization for long periods and in some cases io service times are taking many seconds... which causes thunderbird to timeout when doing things like appending messages to user "Sent" mailboxes. Any ideas? Thanks, Ben Burke

Removing a mailbox from a dovecot cluster
by Francis 26 Feb '19

26 Feb '19

Hello, How should I remove a mailbox from a dovecot cluster? I have two dovecot in a cluster. I tried to remove one user's mailbox with theses commands I found with a little google search: doveadm flags add -u user(a)domain.tld "\\Deleted" ALL doveadm expunge -u user(a)domain.tld mailbox "*" DELETED doveadm purge -u user(a)domain.tld rm -fr /var/vmail/domains/domain.tld/user If I do theses commands in a script (so one command after one, very quick), the data just keep coming back from the other server in the cluster (I suppose this is what's happening). If I do theses commands manually, so more slowly, the mailbox is created again but empty this time. If I connect from an IMAP client, I see an empty mailbox. Same thing if I connect an IMAP client to the second server from the cluster. But I still see the data in the storage (mdbox) of the second server (the "m.#" files are still there an they waste space on disks). I tried to do a "doveadm purge" on the second server, but it did nothing more, the data is still keep on the disks. I'm running dovecot 2.2.33.2 on ubuntu 18.04 on both servers. Thanks! -- Francis

Virus scan + removal on a mdbox mail storage
by Christoph Haas 26 Feb '19

26 Feb '19

Hi, I need advice on how virus scan and removal can be done on a _mdbox_ mail storage? On a maildir storage the virus scanner (e.g. clamav etc.) can detect and remove a email that is infected, since every email and attachment are stored in separate files. But in mdbox the emails and attachments are compressed together in one ore more mdbox-files ... I am anxious to convert my mail storage for virus scanning into maildir format, since I don't know if a virus or crypto trojan con be activated with this converting action =:-o Cheers Christoph. -- Christoph Haas

Linking mailboxes

Hi, I am new to Dovecot and I am trying to link an email account folder to another Maildir(its a backup of the older email). I want the email account to be able to access the older emails. I am assuming this is done by creating a symlink? Currently reading instructions on this page:- https://wiki.dovecot.org/SharedMailboxes/Symlinks At the moment I have the folder:- /var/mail/vhosts/example.com/email1/Maildir/.INBOX.newfolder Inside the folder:- drwx------. 2 vmail vmail 4096 Feb 23 13:39 cur -rw-------. 1 vmail vmail 232 Feb 23 13:43 dovecot.index.log -rw-------. 1 vmail vmail 51 Feb 23 13:43 dovecot-uidlist -rw-------. 1 vmail vmail 0 Feb 23 13:39 maildirfolder drwx------. 2 vmail vmail 4096 Feb 23 13:39 new lrwxrwxrwx. 1 root root 45 Feb 23 13:46 Other -> /run/media/computer/Storage/Email/mail/Other drwx------. 2 vmail vmail 4096 Feb 23 13:39 tmp lrwxrwxrwx. 1 root root 5 Feb 23 13:46 Users -> Users I am not able to access the folders in the Other folder structure(inside other there are other email inboxes ie(email1@example.com,email2@example.com,etc.). I want to get access to all the email subfolders. Could someone here advise how to do this or point me to some tutorials for this. Sincere apologies for this and many thanks in advance for helping...

Corrupted transaction log and redownloading
by azurit＠pobox.sk 25 Feb '19

25 Feb '19

Hi, today we had to hard-reboot one of our dovecot proxy backends and after boot up, lot's of accounts were showing this error and appeard empty: Error: Corrupted transaction log file ... After deleting the indexes (not uid file, problem wasn't in deleting indexes, i'm doing this often), e-mails showed up ok but e-mail clinets started to download them again. Why this happened and how to prevent it (other than 'not hard-rebooting')? I know that reboot could cause corruption of uid files in some cases but this time it looks like this was caused by corrupted indexes - how index corruption can cause redownloading and why? Thanks for any info. azur

password protected ssl key seems unsupported after update to 2.3.4.1
by admin＠f-hamelin.fr 25 Feb '19

25 Feb '19

Hi, On a debian server after an update to dovecot to 2.3.4.1 imaps mail client stop working. I’ve applied necessary migration for ssl_dh (cf https://wiki.dovecot.org/Upgrading/2.3 <https://wiki.dovecot.org/Upgrading/2.3> ) but that was not enough.

permission denied errors with INDEX=MEMORY and trees plugin
by John McKay 24 Feb '19

24 Feb '19

I am using the trees[1] plugin to encrypt the mail on my disk. Because I don't want it to store any metadata in plaintext, I've also set INDEX=MEMORY in my mail_location configuration. However, whenever I get new mail I get errors like the following showing up in the journal: lmtp(john(a)octet.space)<21780><QDkrBqTXclwUVQAAQHGRUQ>: Error: Mailbox INBOX: Saving mail: read(/var/vmail/octet.space/john/Maildir/tmp/1551030180.M508113P21780.toaster.octet.space) failed: Permission denied (read reason=header Subject (Cache file is unusable)) It's like it's trying to read the message after it's been delivered, but is not able to because it's been encrypted. I seem to be able to get email just fine despite the error message. This happens both if I deliver mail using dovecot-lda or lmtp. Is there any way to fix this or at the very least suppress the error message? I have included my dovecot configuration below.

LMTP and public mailboxes?
by Eric Abrahamsen 22 Feb '19

22 Feb '19

Hi, I've been using postfix and dovecot for a few years, and have been doing public mailboxes with dovecot-lda, using a postfix transport that looks like (line wrapped for the mailer): my-public-transport unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -u <me> -e \ /usr/lib/dovecot/dovecot-lda -f ${sender} -d <me> -m public/${user} So messages first passed to spamassassin, using my own personal config for bayes rules, then to dovecot-lda, using my user for auth, and finally delivering to a public/* mailbox, with acl rules for access. I'm moving spamassassin to a mimedefang milter, so that's out of the equation; and LDA to LMTP, so the postfix config simply becomes: virtual_transport = lmtp:unix:private/dovecot-lmtp That's much nicer, but I'm not sure how to handle the public mailbox using LMTP. How are people doing this? While Googling I saw a recommendation to create a virtual user for the public mailboxes, and then presumably Postfix would map "info(a)mydomain.com" to "publicuser+info(a)mydomain.com" and I would go from there. But that seems a little weird: I don't want anyone to be able to log in as publicuser, nor to send mail as that user (Postfix uses Dovecot for auth). Yet I don't seem to be able to pass other arguments to lmtp, that might indicate which user to use for auth. Does anyone have a clean solution for this? Thanks in advance, Eric

Sieve vnd.dovecot.filter hanging issue
by Scott M. 22 Feb '19

22 Feb '19

I am trying to add a signature to all messages and it should be possible via vnd.dovecot.filter, the problem is that any script I try to filter through just hangs. I am running on FreeBSD 11.2 and I tried with dovecot 2.2.32 & pigeonhole 0.4.19 and with dovecot 2.3.2 && pigeonhole 0.5.2. In both cases, the output from dovecot is the same: Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: sieve: action filter: running program: append Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: Mailbox stdin: Opened mail UID=1 because: mail stream Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: waiting for program `/usr/local/gtech/sieve/append' to finish after 3 msecs Feb 19 18:25:22 mx13 dovecot: lda(user1): Debug: program `/usr/local/gtech/sieve/append'(55055) execution timed out after 60000 milliseconds: sending TERM signal Feb 19 18:25:27 mx13 dovecot: lda(user1): Debug: program `/usr/local/gtech/sieve/append' (55055) did not die after 5000 milliseconds: sending KILL signal at first I tried using my actual script but since it was failing I switched to a simple shell script: #!/bin/sh cat /dev/null echo "hey" exit 0 I got that idea after reading: http://dovecot.2317879.n4.nabble.com/execute-sieve-command-fails-to-notice-… (http://dovecot.2317879.n4.nabble.com/execute-sieve-command-fails-to-notice-…) The result is unfortunately the same. From what I can gather ( ran it inside strace/truss too), dovecot-lda hangs on the output. Is this accurate ? How can I get this to work ?

Using SHA256/512 for SQL based password
by Robert Moskowitz 21 Feb '19

21 Feb '19

I have trying to find how to set the dovecot-sql.conf for using SHA256/512. I am going to start clean with the stronger format, not migrate from the old MD5. It seems all I need is: driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=$Postfix_Database_Password default_pass_scheme = SHAxxx-CRYPT # following should all be on one line. password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 101 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' # following should all be on one line user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 101 AS uid, 12 AS gid, CONCAT('*:messages=30000:bytes=', quota) as quota_rule FROM mailbox WHERE username = '%u' AND active = '1' where xxx is either 256 or 512. All the rest I have been finding in my searches concern converting the format and are not needed for a clean start? thanks

sieve filter not working
by subin ks 20 Feb '19

20 Feb '19

I've Dovecot and dovecot-sieve v 2.2.27 installed on a Debian 9.6. I'm trying to set a Sieve filter which will redirect all emails from `info` (i.e. .info) TLD to another email. This is the filter: require ["regex"]; # rule:[test] if header :regex "from" "info$" { redirect "subbs(a)domain.com"; } It's not being honored; all emails from .info TLD ends up in the inbox and none are redirected. Let me know what I'm doing wrong. Thanks.

Need to authenticate Outlook and NTLM
by Mark Foley 20 Feb '19

20 Feb '19

I've posted questions on this before, but now I really, really need a solution. Using Dovecot 2.2.33.2 We've been using Dovecot as IMAP server for several years on a Linux host which is also the Active Directory / Domain Controller. We have both Thunderbird and Outlook clients. The Thunderbird clients authenticate w/o problem with AD credentials using Kerberos/GSSAPI. I've never been able to get the Outlook clients to authenticate using domain credentials, so I've also hard-coded user and password into /etc/passwd and let the Dovecot authenticate via PLAIN LOGIN. Now, however, I am mandated to switch all users to Outlook, so I need an AD credential solution. I found https://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm and followed those instructions. The first problem I ran into was in Step 3 where it said to put the following line in the config: auth_ntlm_use_winbind = yes This gave me an error when I restarted Dovecot: Restarting Dovecotdoveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-auth.conf line 84: Unknown setting: auth_ntlm_use_winbind googling this error indicated that this was a version 1.x directive and 2.x used only auth_use_winbind. I removed the auth_ntlm_use_winbind and Dovecot restart. If this is true, the wiki should be updated since it purports to be a version 2.x wiki. I followed the rest of the instructions on that wiki and my modified config is: $ doveconf -n # 2.2.33.2 (d6601f4ec): /usr/local/etc/dovecot/dovecot.conf # OS: Linux 4.4.157 x86_64 Slackware 14.2 auth_debug = yes auth_debug_passwords = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi ntlm auth_use_winbind = yes auth_username_format = %n auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/2016-08-10/54e789087d419b6e.crt ssl_key = # hidden, use -P to show it userdb { driver = passwd } verbose_ssl = yes New additions to my pre-ntlm conf is only the 'ntlm' added the the auth_mechanism and: auth_winbind_helper_path = /usr/bin/ntlm_auth which interestingly doesn't show into the 'doveconf -n' output, above. Is it a default? I then attempted to connect from Outlook and got the error: auth: Info: ntlm(?,192.168.0.58,<qd9nulmB4sLAqAA6>): ntlm_auth reports broken helper: NT_STATUS_UNSUCCESSFUL After more searching I came across this post, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774263 which, in summary, said that ntlm_auth had to run as root. So, I added the following to my dovecot config per that post's suggestion: service auth { user = root } After restarting and trying again to connect from Outlook I got the message: auth: Info: ntlm(?,192.168.0.58,<SCINjFqBKcXAqAA6>): user not authenticated: NT_STATUS_NO_MEMORY At this point I've been unable to find a solution to this error. I've listed the entire dovecot log output for this last attempt to connect from Outlook below. Has anyone in the Universe successfully connected from Outlook using active domain credentials? If so, what's the secret? What am I not doing correctly?

Virtual mailbox shows mails that are too old
by Stefan Hagen 19 Feb '19

19 Feb '19

Hello, I'm using dovecot on my personal / private email server. I have set up virtual mailboxes in my inbox namespace like this: namespace inbox { inbox = yes prefix = "Virtual/" separator = / location = "virtual:~/.emails_virtual:LAYOUT=fs:INDEX=dovecot.virtual.index:LISTINDEX=dovecot.virtual.list.index" list = yes subscriptions = yes mailbox { auto = subscribe } } I had quite some trouble with it at first with UIDs changing all the time, but after adding INDEX and LISTINDEX it started to work just fine. I've created dovecot_virtual files like this one: $ cat ~/.emails_virtual/2-LastDay/dovecot-virtual * -Trash -Sent -Drafts -Spam -Virtual -Virtual/* all younger 86400 After stopping dovecot and deleting the index files and restarting dovecot, the virtual mailbox shows all mail from the last day - as expected. But after one day, it shows mail from two days. After three, it shows mails from three days. It looks like dovecot selects emails from the last day, but never cleans out emails that are older, once they have been selected. My full dovecot -n can be found here: https://codevoid.de/?q=/0/p/dovecot-n.txt Any ideas about what could be wrong?

dovecot/lmtp dumps core when proxying to multiple recipients via protocol=smtp
by Piper Andreas 19 Feb '19

19 Feb '19

Hello, when trying to set up a migration scenario from my old mailbox-servers to my new dovecot-cluster, I get a coredump from dovecot/lmtp when proxying mail-delivery to more than one recipient on the old mailbox-server. My setup: 3 director-hosts (Debian stretch) are proxying to a pair of replicator-hosts and during migration also to the old mailbox-server. For migration the not-migrated user-addresses are included via a passwd-file with entries like: grtest1@hrz.uni-marburg.de:::::::director_tag=hrz protocol=smtp user=grtest1 grtest2@hrz.uni-marburg.de:::::::director_tag=hrz protocol=smtp user=grtest2 ... The director_tag points to the old mailbox-server, with 'protocol=smtp' SMTP is used for delivery, as the old machine is not capable of LMTP. The setup works fine for imap-proxying and for mail-delivery to single recipients. But if a mail is addressed to more than one recipient, lmtp produces a coredump after delivering to all recipients. The error-message in the log is: Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Connect from 127.0.0.1 Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (1/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (2/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Fatal: master: service(lmtp): child 64663 killed with signal 11 (core dumped) The backtrace from the coredump is: Reading symbols from /usr/lib/dovecot/lmtp...(no debugging symbols found)...done.

Migrate mail data from Dovecot to Dovecot
by Odhiambo Washington 19 Feb '19

19 Feb '19

I have built a new server (FreeBSD-12) running dovecot-2.3.4. My old server (FreeBSD-9.3) is running dovecot-2.3.4 as well. The configurations are 1:1 identical. The are about 250 users on this server, all virtual. They are mostly POP3 users, but they do "leave a copy of message on the server" for set various number of days. Now, to migrate the mail data, can I simply rsync the mail directories between the old and the new server? Would that create a pitfall?? What is the recommended method? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)

Error configuring unix_listener stats-writer
by Peter Nabbefeld 18 Feb '19

18 Feb '19

Hello, I've got a very strange problem: When I try to configure the stats-writer socket, I'm told the configuration is a duplicate, though none exists in the configuration files. So I'd guess the configuration is set either built-in or implicitly. I've put the following into conf.d/10-master.conf: service auth { unix_listener auth-userdb { } unix_listener stats-writer { user = vmail group = vmail mode = 0666 } } BTW, using imap for mail traffic. Is there any tool displaying an "effective" config tree (i.e., a tool displaying the resulting configuration from every file, displaying the original file and line number)? "dovecot -a" only displays all configurations, but without source reference, so it's impossible to find out about the details. :-( Kind regards Peter

Dsync and network issues
by Danilo G. Baio 18 Feb '19

18 Feb '19

Hi. Our scenario: dovecot-2.3.4.1 Two FreeBSD servers, A (master) and B (slave). replication_max_conns = 10 doveadm_port = 60025 All mails are received on server A and replicated to server B. Sometimes we get these messages on server B: Feb 18 08:27:35 dsync-server(XX@XX): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:28:00 dsync-server(XZ@XZ): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:33:14 dsync-server(XY@XY): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:44:07 dsync-server(XW@XW): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer It happens sometimes (usually early morning) when users are syncing their mailboxes. Is there a way to debug this and find what is happening? Thanks for your time. -- Danilo G. Baio
