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?

same account imap and pop3
by James 02 Mar '19

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. The workaround I’ve setup was to remove password protection from the ssl_key file. All tests with ssl_key_password parameter failled (direct password, <path-file-with-password) searching I’ve found a message reporting a problem with that parameter and Stephan said it was tracked internally as DOP-851 Hope this will help.
