Hi Anyone can help on those memory leaks since 2.3.17 ? These came after adding the fts_mail_user_init(user, FALSE, &error) and fts_mail_user_deinit(user) function calls to avoid breaking due to change in the API Thank you for help doveadm: Warning: Event 0x5563f3f2b740 leaked (parent=0x5563f3f2b330): mail-user.c:78 doveadm: Warning: Event 0x5563f3f2b330 leaked (parent=(nil)): mail-storage-service.c:1359 doveadm: Warning: Event 0x5563f4009ef0 leaked (parent=0x5563f3f4cf80): mail-index.c:67 doveadm: Warning: Event 0x5563f40096c0 leaked (parent=0x5563f3f4cf80): fs-api.c:32 doveadm: Warning: Event 0x5563f40092b0 leaked (parent=0x5563f3f4cf80): mail-storage.c:430 doveadm: Warning: Event 0x5563f3f4cf80 leaked (parent=0x5563f3f21f00): mail-user.c:78 doveadm: Warning: Event 0x5563f3f21f00 leaked (parent=(nil)): mail-storage-service.c:1359 doveadm: Warning: Event 0x5563f3f2d080 leaked (parent=0x5563f3f234f0): mail-index.c:67 doveadm: Warning: Event 0x5563f3f2c820 leaked (parent=0x5563f3f234f0): fs-api.c:32 doveadm: Warning: Event 0x5563f3f2c300 leaked (parent=0x5563f3f234f0): mail-storage.c:430 doveadm: Warning: Event 0x5563f3f234f0 leaked (parent=0x5563f3f4e1d0): mail-user.c:78 doveadm: Warning: Event 0x5563f3f4e1d0 leaked (parent=(nil)): mail-storage-service.c:1359 doveadm: Warning: Event 0x5563f3f24d20 leaked (parent=0x5563f3fd58b0): mail-index.c:67 doveadm: Warning: Event 0x5563f3f24620 leaked (parent=0x5563f3fd58b0): fs-api.c:32 doveadm: Warning: Event 0x5563f3f23e30 leaked (parent=0x5563f3fd58b0): mail-storage.c:430 doveadm: Warning: Event 0x5563f3fd58b0 leaked (parent=0x5563f3fd54a0): mail-user.c:78 doveadm: Warning: Event 0x5563f3fd54a0 leaked (parent=(nil)): mail-storage-service.c:1359 doveadm: Warning: Event 0x5563f3fd6df0 leaked (parent=0x5563f3fcc8a0): mail-index.c:67 doveadm: Warning: Event 0x5563f3fd65c0 leaked (parent=0x5563f3fcc8a0): fs-api.c:32 doveadm: Warning: Event 0x5563f3fd5dd0 leaked (parent=0x5563f3fcc8a0): mail-storage.c:430 doveadm: Warning: Event 0x5563f3fcc8a0 leaked (parent=0x5563f3f1c990): mail-user.c:78 doveadm: Warning: Event 0x5563f3f1c990 leaked (parent=(nil)): mail-storage-service.c:1359 doveadm: Warning: Event 0x5563f3f16a20 leaked (parent=0x5563f3fbb710): mail-index.c:67

Dovecot v2.3.17 released
by Aki Tuomi 04 Nov '21

04 Nov '21

We are pleased to release v2.3.17 of Dovecot. Please note that 2.3.17 release will be the last one to support Debian/Stretch since Bullseye is now supported. https://dovecot.org/releases/2.3/dovecot-2.3.17.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.17.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Regards Aki Tuomi Open-Xchange oy --- * Dovecot now logs a warning if time seems to jump forward at least 100 milliseconds. * dict: Lines logged by the dict process now contain the dict name as the prefix. * lib-index: mail_cache_fields, mail_always_cache_fields and mail_never_cache_fields now verifies that the listed header names are valid. Especially the UTF8 "–" character has sometimes been wrongly used instead of the ASCII "-". + *-login: Added login_proxy_rawlog_dir setting to capture rawlogs between proxy and backend. + dict: The server process now keeps the last 10 idle dict backends cached for maximum of 30 seconds. Practically this acts as a connection pool for dict-redis and dict-ldap. Note that this doesn't affect dict-sql, because it already had its own internal cache. + doveadm: New stats add/remove commands added to support changing the metrics configuration on runtime. + lazy_expunge: Added lazy_expunge_exclude settings to disable lazy_expunge for specific folders. \Special-use flags can be used as folder names. + lib-lua: Added a new helper function dovecot.restrict_global_variables() to disable or enable defining new global variables. - LAYOUT=index List index rebuild was missing. - LAYOUT=index: Duplicate GUIDs were not detected. - acl: When using acl_ignore_namespace Dovecot attempted to access or create dovecot-acl-list even when the namespace should have been ignored. For virtual namespaces this could have yielded errors about "Read-only file system" or "Permission denied". - auth: Setting the "master" passdb field to empty value would cause proxying to fail with an authentication error. Now an empty "master" field is ignored. - doveadm-server: Duplicate error lines were sent for failed commands. This didn't normally cause visible problems, except when using wildcards in usernames or -A parameter to go through multiple users. - doveadm-server: Logs written by doveadm-server were often missing log prefixes, especially mail_log_prefix for mail commands. Logs sent to doveadm TCP client were also missing log prefixes. - doveadm: v2.3 regression: batch command always crashes. - doveadm: v2.3.11 regression: Commands failed if ssl_cert or ssl_key files weren't readable by the user running doveadm, even though doveadm didn't actually use these settings - imap-hibernate: Process may crash at deinit: Panic: file ioloop.c: line 928 (io_loop_destroy): assertion failed: (ioloop->cur_ctx == NULL). - imap: Using imap_fetch_failure=no-after can cause assert-crash with some IMAP commands if reading the mail fails (e.g. wrong cached mail size). Fixes: Panic: file index-mail-headers.c: line 198 (index_mail_parse_header_init): assertion failed: (!mail->data.header_parser_initialized) - imap: v2.3.10 regression: When using INDEXPVT to enable private \Seen flags (for shared or public namespaces) the STORE command did not send untagged replies for the \Seen flag changes. - imap: v2.3.15 regression: If PREVIEW/SNIPPET is not the final FETCH option in the command, the IMAP FETCH response is broken. - imap: v2.3.15 regression: MOVE command leaks mailbox if it can't be opened and crashes at deinit: Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed: ((*user)->refcount == 1). - imapc: Copying nonexistent mail via imapc could have crashed. Fixes: Panic: file mail-storage.c: line 2385 (mailbox_transaction_commit_get_changes): assertion failed: (ret < 0 || seq_range_count(&changes_r->saved_uids) == save_count || array_count(&changes_r->saved_uids) == 0). - indexer: v2.3.15 regression: Process crashes if indexer-client disconnects while it's waiting for command reply. This happened for example if IMAP SEARCH triggered long fts indexing and the IMAP client disconnected while waiting for the reply. - indexer: v2.3.15 regression: Process may have crashed in some situations. - indexer: v2.3.15 regression: indexer-worker processes may not have reached the process_limit in some situations, possibly even using just one indexer-worker process even though there were many indexing requests queued. - lib-compression: Reading lz4 compressed mdbox mails may crash. Fixes: Panic: file istream.c: line 345 (i_stream_read_memarea): assertion failed: (!stream->blocking). - lib-compression: bench-compress crashes due to xz being read-only. - lib-lua: Fix linking libdict_lua for non-GNU linkers when Lua support is disabled. - lib-mail: There was no limit on how large an email header name could be. Processable header names are now limited to 1000 bytes. - lib-oauth2: Dovecot disallowed JWT tokens if their validity time was older than token creation time (nbf < iat). - lib-storage: Reduce memory footprint of certain storage operations. - lib-storage: When listing mailboxes with storage name escape characters (^ or .) as part of the mailbox name, the listing could show corrupted mailbox names. Due to an issue in handling escaped parent folders, the listing of other mailbox names would become corrupted by prepending parts of the previously listed mailboxes parent folder as prefix to the actual mailbox names. The corruption can occur when using LAYOUT=INDEX and maildir or obox, or when using the listescape plugin. - mail-crypt: Fix "-O" argument for "doveadm mailbox cryptokey password" command to be a boolean, and not expect a string. - submission-login: Add support for not authenticating to next hop in submission proxying. - submission-login: EHLO was not sent again after XCLIENT when doing submission proxying. - virtual: Mailboxes do not correctly detect underlying mailboxes getting re-created even though they have a different UIDVALIDITY or GUID.

disable sieve replication with dsync
by David Mandelberg 04 Nov '21

04 Nov '21

Hi, I think I got dsync working for mail, but I'm getting these errors: Error: sieve: file storage: mkdir_parents_chgrp(/usr/local/etc/mail/mandelberg.org/david/sieve/tmp) failed: Read-only file system I'm managing sieve files externally, and I don't want any part of dovecot writing to them. Is there any way to configure dsync to not replicate them? I looked at doveadm-sync(1) to see about adding a flag to replication_dsync_parameters, but the closest thing I see is -x for excluding mailboxes. Or maybe -o? Is there a way to specify a nested setting to -o, so I could do something like `plugin { sieve = }` for dsync?

Is there some info on what to expect how big these indexes can get (% mailbox)? Is there any differences between solr / xapian storage use? https://github.com/slusarz/dovecot-fts-flatcurve/

I was not having the exit trap and the sleep+kill, I don't really get why it is necessary to have these. Looks a bit inefficient to me having a sleep and to kill your own process.

Auth-Trouble

Hi, I've installed Dovecot on a freshly installed machine running Freebsd 13.4. Configuration was copied from an earlier installation, which worked perfectly, until I screwed an update. AFAICS things are working, except replication. I see tons of Errors on the remote and the local machine Oct 31 16:15:30 freebsd dovecot[3248]: doveadm(xxx(a)xx.de): Fatal: connect(213.239.197.36:54321) failed: Interrupted system call and some Oct 31 16:47:33 freebsd dovecot[5509]: auth: cram-md5(xxx(a)xx.de,176.199.241.57,<xSyR+afPn9ywx/E5>): Password mismatch Oct 31 16:47:28 freebsd dovecot[5509]: doveadm(xxx(a)yy.de): Fatal: connect(213.239.197.36:54321) failed: Connection refused and we also get Oct 31 18:17:17 freebsd dovecot[934]: imap(xxx(a)wxxx.de)<1649><lWFvO6nPDeewx/E5>: Panic: file array.c: line 10 (array_idx_modifiable_i): assertion failed: (idx < array->buffer->used / array->element_size) Oct 31 18:17:17 freebsd dovecot[934]: imap(xxx(a)wxxx.de)<1649><lWFvO6nPDeewx/E5>: Fatal: master: service(imap): child 1649 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set service imap { drop_priv_before_exec=yes }) not to forget Oct 31 18:18:33 freebsd dovecot[934]: doveadm(xxx@xxx): Fatal: connect(213.239.197.36:54321) failed: Connection refused Users are authenticating with ldap.

Shared folders - dovecot.index.pvt view is inconsistent
by Felix Ingram 03 Nov '21

03 Nov '21

Hello all, As part of the system I'm cobbling together, I have a need for sharing folders between users. I've followed the various pieces of documentation and seem to have something working but have encountered an odd issue. When user1 shares a folder with user2, then on first access user2 gets a "permission denied" error when trying to access the folder. If I immediately try to access the folder again, then everything is okay. The logs talk about the index.pvt files being inconsistent, which seems to result in the error the first time but allows access the second. I've searched the mailing lists and it seems that this was seen a few years ago and is due to the index files being empty but there didn't seem to be a resolution. At the moment, I am filing messages into folders under INBOX, which means that the INBOX itself is empty (though I've seen the same behaviour if I put some messages in there as well). Can anyone suggest a fix/workaround? I've included my config and some log entries below. In the logs, the "tester@..." user is trying to access the folder "INBOX/tester2" shared by "foo123@...". (Bonus question: can anyone suggest a mail client that allows easy access to shared folders? For the life of me I can't see how to do it in Thunderbird, so I'm using a python script at the moment.) Thanks in advance, Felix # 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.2 () # OS: Linux 5.10.16.3-microsoft-standard-WSL2 x86_64 Ubuntu 20.04.3 LTS overlay # Hostname:
