How to use xapian with non-text attachments
by André Rodier 03 Jul '21

03 Jul '21

Hello, I am developing a hosting platform on Debian Bullseye, with Dovecot amongst other tools. I am trying to use the xapian full test search plugin, but I can see the attachments are skipped: This is what I have in the logs when running the indexing in verbose mode: ----------------------------------------------------------------------- doveadm(camille): Info: FTS Xapian: fts_backend_xapian_check_access doveadm(camille): Info: FTS Xapian: Memory stats : Used = 56 MB, Free = 66 MB doveadm(camille): Info: FTS Xapian: fts_backend_xapian_index_hdr doveadm(camille): Info: FTS Xapian: fts_backend_xapian_query doveadm(camille): Info: FTS Xapian: Query= uid:"44" doveadm(camille): Info: FTS Xapian: Ngram(S) -> 63 items (total 0 KB) doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_unset_build_key doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Message- Id,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_build_more doveadm(camille): Info: FTS Xapian: fts_backend_xapian_check_access doveadm(camille): Info: FTS Xapian: Memory stats : Used = 56 MB, Free = 66 MB doveadm(camille): Info: FTS Xapian: fts_backend_xapian_index_hdr doveadm(camille): Info: FTS Xapian: fts_backend_xapian_query doveadm(camille): Info: FTS Xapian: Query= uid:"44" doveadm(camille): Info: FTS Xapian: Ngram(XMID) -> 4 items (total 0 KB) doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_unset_build_key doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=X- Mailer,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'xmailer' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=MIME- Version,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'mimeversion' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content- Type,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contenttype' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Authentication- Results,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'authenticationresults' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=X-AV- Checked,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'xavchecked' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content- Type,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contenttype' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=(null),Type=text/plain,Disposition=(null)) doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_build_more doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_unset_build_key doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content- Type,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contenttype' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content- Description,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contentdescription' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content- Disposition,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contentdisposition' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=Content-Transfer- Encoding,Type=(null),Disposition=(null)) doveadm(camille): Info: FTS Xapian: Unknown header (indexing) 'contenttransferencoding' doveadm(camille): Info: FTS Xapian: fts_backend_xapian_update_set_build_key doveadm(camille): Info: FTS Xapian: New part (Header=(null),Type=text/csv,Disposition=attachment;

Thanks a lot for your help! André

How can I prevent sieve filter from being applied to some mail users?
by yuryb 02 Jul '21

02 Jul '21

We have an emarket(a)example.com mailbox that receives orders from customers. Postfix redirects such emails to the email addresses of our sales managers, as well as to the special address parser(a)example.com, which is used by some analytical software. For this, a file named "Virtual" has been created in the Postfix folder with the following contents:emarket@example.com manager1@example.com,manager2@example.com,manager3@example.com,parser@example.comIn addition, Dovecot places all such emails in the Orders folder of each sales manager. For this, a Sieve filter rule has been created: require ["fileinto", "envelope"]; if envelope: is "to" "emarket(a)example.com" { fileinto "Orders"; stop; } But the problem is that the analytics software that uses the parser(a)example.com mailbox is subscribed only to the default Inbox folder. And it doesn't know how to work with the Orders folder. So I need to somehow prevent the filter from being applied to the parser(a)example.com mailbox. How can I do this using Dovecot or Sieve?

Bug: empty prefix value in userdb lookup defaults to "yes"?
by Dan Malm 02 Jul '21

02 Jul '21

Hi, I'm trying to migrate some users into our system from another one that also run dovecot but with different prefix and separator settings than we do. I've setup userdb to return these values for a test user to match the other systems separator/prefix setup: { "home": "/customers/b/5/3/cdeadbeef/mail/m0123456789abcdef/", "namespace/inbox/separator": "/", "uid": 10000001, "namespace/inbox/prefix": "", "gid": 10000001 } But the empty value for prefix seems to get converted to some default value of "yes" as when I log in with that user dovecot throws this error: Error: namespace configuration error: list=yes requires prefix=yes to end with separator / Dovecot version: 2.3.13 OS: Ubuntu 20.04.2 -- BR/Mvh.

Pigeonhole bug: corrupted redirected emails
by Peter Williams 01 Jul '21

01 Jul '21

Hello, (Please CC me on any replies since I'm not subscribed to this mailing list.) I'm writing to report a bug that I just ran into, involving Sieve/Pigeonhole message redirections. I recently added a rule involving redirections and the redirected messages were getting corrupted. I traced the issue down to the fact that an Mbox-style "From " header line was getting intermixed with the message headers -- note the entry between the two "Received:" headers in this example, which shows the text being delivered to the MTA on stdin: X-Sieve: Pigeonhole Sieve 0.4.24 (124e06aa) X-Sieve-Redirected-From: peter Delivered-To: peter Received: from dovecot by newton.cx with LMTP id xxx for <peter>; Thu, 01 Jul 2021 04:32:50 +0000 From peter(a)newton.cx Thu Jul 01 04:32:50 2021 Received: from xxx by newton.cx with esmtpsa xxx (Exim 4.94.2) (envelope-from <peter(a)newton.cx>) id xxxx for peter(a)newton.cx; Thu, 01 Jul 2021 04:32:50 +0000 Message-ID: <xxx> Subject: qqtestqq This was happening with trivial test messages, and trivial Sieve rules, but I can provide specifics if they would be helpful. Versions: CentOS 7.9.2009; Dovecot 2.2.36; Pigeonhole 0.4.24; Exim 4.92.2. Below I've added the output of `dovecot -n`. My `sendmail_path` setting was empty before, but as a workaround I've set it to a wrapper script that strips out everything before the `From `, "solving" the problem. Thanks so much for building Dovecot, I've been using it with great success for more than a decade!

Dovecot sync broke after upgrade to OpenBSD 6.9
by William Orr 01 Jul '21

01 Jul '21

Hey, I have two mailservers running OpenBSD 6.9, and I use bidirectional syncing of my maildirs through doveadm. After the upgrade, I noticed that the sync process was failing. OpenBSD 6.8 shipped with Dovecot 2.3.13, 6.9 ships with 2.3.14. Here's the output of the dovecot --build-options: kefka|~|03:01:50|89$ dovecot --build-options Build options: ioloop=kqueue notify=kqueue openssl io_block_size=8192 SQL driver plugins: mysql postgresql sqlite Passdb: bsdauth checkpassword ldap passwd passwd-file sql Userdb: checkpassword ldap(plugin) passwd prefetch passwd-file sql I did not compile this manually, this is from packages. More info about configure options passed are available here, in the Makefile from ports https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/mail/dovecot/Makefile?rev=1… Here's a sample run of the sync: kefka|~|02:57:05|0$ doas doveadm sync -u worr(a)worrbase.com remote:sabin.worrbase.com doveadm(VERSION dsync 3 5): Error: User doesn't exist dsync-local(worr)<FNQIMvI9omB4VwEADTvxNg>: Error: read(sabin.worrbase.com) failed: EOF (version not received) dsync-local(worr)<FNQIMvI9omB4VwEADTvxNg>: Error: Remote command returned error 67: /usr/bin/ssh -i /root/.ssh/id_ed25519.dsync sabin.worrbase.com /usr/local/bin/dsync-in-wrapper.sh kefka|~|02:57:08|75$ cat /usr/local/bin/dsync-in-wrapper.sh #!/bin/ksh read username /usr/local/bin/doveadm dsync-server -u "$username" I ktraced the process, and noticed that in the communication with the remote mail server, that a bunch of doveadm plugins fail to load. It's worth noting that these are plugins that are dlopen(3)ed in response to certain commands sent over the wire, so they don't show up in ldd(1) output. kefka|~|03:00:08|0$ doas kdump | grep symbol

Pigeonhole - Auto create default per user script
by dovecot＠ptld.com 01 Jul '21

01 Jul '21

Is there a way to have a per-user default sieve script get auto created if it doesn't exist? Or created on first time use like when the directory set by plugin{sieve=file:~/} gets created? Not global scripts.

Pigeonhole sieve_user_log
by dovecot＠ptld.com 01 Jul '21

01 Jul '21

https://doc.dovecot.org/configuration_manual/sieve/configuration/ Pigeonhole creates logs separate from main dovecot logs. I see sieve_user_log allows you to change log location and it says if you don't set it logs are still made by default. I can not find anything about log rotation of these pigeonhole logs or if there is a way to disable this logging. Do i need to worry about this log growing out of control? Is there a way to disable it? Does it prune/purge itself? Any practical reason to keep these logs?

Feature/patch request
by Bucher, Dr. Damian 30 Jun '21

Hi, we ran into a problem, while using filesystem snapshots on a GPFS-filesystem. With this we want to give the users the opportunity to restore Mailboxes from this snapshots in case they deleted mail by accident. For each snapshot we create a namespace via a postlogin skript (with INDEX=MEMORY to avoid writing index files to a ro filesystem). The snapshot are of course read only. When accessing the mailboxes in the namespaces, dovecot generates an error (ro filesystem): Error: Mailbox #backup20/Mail/deleted-messages: open() failed with mbox: Read-only file system We tracked that down to a problem in src/lib-storage/index/mbox/mbox-file.c (yes, we are still using mbox ;) ) fd = open(mailbox_get_path(&mbox->box), mbox_is_backend_readonly(mbox) ? O_RDONLY : O_RDWR); if (fd == -1 && errno == EACCES && !mbox->backend_readonly) { mbox->backend_readonly = TRUE; fd = open(mailbox_get_path(&mbox->box), O_RDONLY); } Here the mailbox is opened and it is checked wether the file is ro or rw. Since the snapshot contains the original file permissions, the file is of course rw, but the filesystem is ro. Unfortunately the code only checks for file permissions (errno == EACCES), which doesn’t catch our error condition (FS ro). We think that exchanging this to (errno == EACCESS || errno == EROFS) would catch the file system ro error correctly and set the readonly flag correctly and open the mailbox ro. (this probably hast to be done for other mailbox formats in the corresponding files too) What do you think? Is there a chance to implement that in an upcoming release?

oauth2
by Andrea Gabellini 30 Jun '21

30 Jun '21

Hello, Dovecot 2.3.15 installed from repository on CentOS 7.9 I would like to try the oauth2 mechanism to autenticate my users. I have installed a working demo of KeyCloak and I have a working installation of Dovecot 2.3.15 with LDAP backend and plain authentication. My Thunderbird client always says "that the server doesn't manage the authentication method", but with a "openssl s_client -connect" command I get: * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=OAUTHBEARER AUTH=XOAUTH2] IMAP ready. Putting Dovecot in debug I can't see any error or warning on oauth2 authentication. I'm following the offical guide: auth_mechanisms = plain oauthbearer xoauth2 passdb { driver = oauth2 mechanisms = xoauth2 oauthbearer args = /etc/dovecot/dovecot-oauth2.conf.ext } /etc/dovecot/dovecot-oauth2.conf.ext: tokeninfo_url = https://www.googleapis.com/oauth2/v3/tokeninfo?access_token= introspection_url = https://www.googleapis.com/oauth2/v2/userinfo #force_introspection = yes username_attribute = email tls_ca_cert_file = /etc/ssl/certs/ca-certificates.crt I'm using an explicit wrong configuration to thrown some errors and verify that Dovecot is really using the OAUTH2 mechanism, but I don't get any errors... What I'm doing wrong? Thanks, Andrea -- __________________________ Okay, okay, I'll take it back ... UNfuck you ! __________________________ TIM San Marino S.p.A.

Panic indexer-worker on Dovecot 2.3.15

Hi, after the upgrade to dovecot 2.3.15 the Panic: indexer-worker error is still present. I don't know if is related to searching in a Virtual folder (look for my previous email on list with subject "Panic on indexer-worker and Dovecot stop to search on Solr" for more details).

Dovecot 2.3.15 compilation fails
by Andreas M. Kirchwitz 29 Jun '21

29 Jun '21

Hello Dovecot users and developers! Up to Dovecot 2.3.14.1 manual compilation of Dovecot sources was fine, I have an old 32-bit Linux server with GCC 4.4.7 where I compile almost all things manually. Works fine, never had problems with GCC versions. env LDFLAGS="-Wl,--no-as-needed" ./configure --prefix=/usr/local/dovecot --with-ssl=openssl --with-ssldir=/usr/local/dovecot/etc/dovecot/certs make Unfortunately, Dovecot 2.3.15 fails to compile at test-smtp-params.c (works with a recent GCC 11.1.1 on my desktop, but servers usually come with older stuff). I know a little bit of programming but that's above my head what goes wrong here and how I could fix it to continue (so I don't know if that's the only problem or if there will be more). See below (at the end) for the exact error message. I assume this compilation issue was not an intentional change/requirement between 2.3.14(.1) and 2.3.15, it just happened. I don't think that the problem is in "test-smtp-params.c" itself but some declarations somewhere else are missing, but I'm no expert here. There were too many changes in the src/lib-smtp source tree to understand what may have caused this (or maybe it's even somewhere else). Any help is highly appreciated. I'd be happy to help and try out any ideas or patches. I'd like to see that Dovecot can be compiled on as many platforms as possible, as long as there are no fundamental requirements making this impossible. Thanks a lot in advance and keep up the good work, Andreas [last lines of compilation process when error happens] gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -I../../src/lib-settings -I../../src/lib-master -I../../src/lib-sasl -I../../src/lib-ssl-iostream -I../../src/lib-dns -I../../src/lib-program-client -I../../src/lib-mail -DTEST_BIN_DIR=\"/usr/local/src/dovecot-2.3.15/src/lib-smtp/test-bin\" -std=gnu99 -g -O2 -fstack-protector -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/OpenSSL-1.1.1/include -MT test-smtp-params.o -MD -MP -MF .deps/test-smtp-params.Tpo -c -o test-smtp-params.o test-smtp-params.c test-smtp-params.c:29: error: unknown field ‘data’ specified in initializer test-smtp-params.c:29: warning: missing braces around initializer test-smtp-params.c:29: warning: (near initialization for ‘test_params_buffer1.<anonymous>’) test-smtp-params.c:30: warning: missing initializer test-smtp-params.c:30: warning: (near initialization for ‘test_params_buffer1.<anonymous>.<anonymous>.used’) test-smtp-params.c:30: error: unknown field ‘used’ specified in initializer test-smtp-params.c:31: warning: excess elements in struct initializer test-smtp-params.c:31: warning: (near initialization for ‘test_params_buffer1’) test-smtp-params.c:33: error: unknown field ‘data’ specified in initializer test-smtp-params.c:33: warning: missing braces around initializer test-smtp-params.c:33: warning: (near initialization for ‘test_params_buffer2.<anonymous>’) test-smtp-params.c:34: warning: missing initializer test-smtp-params.c:34: warning: (near initialization for ‘test_params_buffer2.<anonymous>.<anonymous>.used’) test-smtp-params.c:34: error: unknown field ‘used’ specified in initializer test-smtp-params.c:35: warning: excess elements in struct initializer test-smtp-params.c:35: warning: (near initialization for ‘test_params_buffer2’) make[3]: *** [test-smtp-params.o] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot-2.3.15/src/lib-smtp' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/src/dovecot-2.3.15/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/dovecot-2.3.15' make: *** [all] Error 2

acl_ignore_namespace & dovecot-acl-list files
by Vincent Brillault 29 Jun '21

29 Jun '21

Hi! After updating to 2.3.15, I was hoping to be able to get rid of some of the work-around I had in place when configuring shared folders in cluster mode in 2.3.14. Unfortunately it seems that I still need one. Running on CentOS7 with both a 'virtual' and 'shared' namespace, whenever I update the global vfile, I'm getting the following warning: ``` Error: open(/etc/dovecot/virtual/.temp.....8536.f1a78823779ee98d) failed: Read-only file system Error: dovecot-acl-list creation failed: safe_mkstemp(/etc/dovecot/virtual/.temp.....8536.) failed: Read-only file system Error: unlink(/etc/dovecot/virtual/dovecot-acl-list) failed: Read-only file system (in acl-backend-vfile-acllist.c:339) ``` I found it weird, as I'm using acl_ignore_namespace to ignore the virtual filesystem, but still dovecot seems to be trying to create a dovecot-acl-list file there. After digging into it and generating a backtrace where that error message is triggered, I believe I've trace it down to `acl_lookup_dict_rebuild`, which doesn't filter out "ignored" namespaces. The attached patch seems to solve the problem for me, but I must admit I didn't test it in depth so I'm not sure if I'm breaking something else... Let me know if I'm missing something, Thanks, Vincent PS: Some details: - Relevant configuration (let me know if I'm missing something): ``` mail_plugins = acl zlib virtual fts fts_solr namespace Virtual { prefix = Virtual/ separator = / hidden = yes list = no subscriptions = no location = virtual:/etc/dovecot/virtual:INDEX=~/virtual } namespace shared { type = shared prefix = shared/%%u/ list = children subscriptions = no location = imapc:~/shared/%%u } plugin { # ACLs acl = vfile:/etc/dovecot/dovecot-acl acl_ignore_namespace = Virtual/ acl_ignore_namespace2 = shared/* acl_shared_dict = proxy::acl } ``` - Backtrace generated manually (adding `backtrace_get(&backtrace)` & printing the result under the `dovecot-acl-list creation failed` error): ``` Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7ff99d364862] -> /usr/lib64/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7ff99d36496e] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xb071) [0x7ff99ca9f071] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_acllist_rebuild+0x1d) [0x7ff99ca9f3ed] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_acllist_refresh+0x250) [0x7ff99ca9f6b0] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_nonowner_iter_init+0x9) [0x7ff99ca9f849] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_lookup_dict_rebuild+0x13e) [0x7ff99caa179e] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xb245) [0x7ff99ca9f245] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_acllist_rebuild+0x1d) [0x7ff99ca9f3ed] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xa9ad) [0x7ff99ca9e9ad] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0x6e4c) [0x7ff99ca9ae4c] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_object_get_my_rights+0x75) [0x7ff99ca9af35] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xe44e) [0x7ff99caa244e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_exists+0x6e) [0x7ff99d6845fe] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_list_mailbox+0x226) [0x7ff99d694ff6] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_list_iter_init_namespaces+0x282) [0x7ff99d6eecf2] -> dovecot/imap [vbrillau XXXXX LIST](cmd_list_full+0x55b) [0x563f9bb004bb] -> dovecot/imap [vbrillau XXXXX LIST](command_exec+0x64) [0x563f9bb0ab04] -> dovecot/imap [vbrillau XXXXX LIST](+0x1d9e2) [0x563f9bb089e2] -> dovecot/imap [vbrillau XXXXX LIST](+0x1da71) [0x563f9bb08a71] -> dovecot/imap [vbrillau XXXXX LIST](client_handle_input+0x205) [0x563f9bb08ef5] -> dovecot/imap [vbrillau XXXXX LIST](client_input+0x79) [0x563f9bb094d9] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x65) [0x7ff99d38a425] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x12b) [0x7ff99d38bdab] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x59) [0x7ff99d38a529] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7ff99d38a768] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7ff99d2f43c3] -> dovecot/imap [vbrillau XXXXX LIST](main+0x342) [0x563f9bafa2f2] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7ff99ced1555] -> dovecot/imap [vbrillau XXXXX LIST](+0xf4f5) [0x563f9bafa4f5] ```

Increase FTS timeouts for slow(er) machines
by Bojan Čekrlić 29 Jun '21

29 Jun '21

Hello list, I have a question which doesn’t seem to be answered by the documentation. I’m running Dovecot on a Raspberry PI-like computer. I’ve enabled full-text search (FTS) and installed Solr and Tika. Now, Dovecot will timeout Tika after 60 seconds and some emails will not get indexed as there’s simply not enough processing power on the device to work so fast. I don’t mind the slowness, so the question here is — how do I increase this timeout? Looking at the commits it seems that this option is hardcoded in the code and cannot be increased via configuration change? Thanks, B

Dovecot mailing list and DKIM
by Kevin N. 28 Jun '21

28 Jun '21

Hello everybody, Going through my mail logs I noticed that a couple of messages from the Dovecot mailing list failed DKIM validation. For example, this one has failed: https://markmail.org/message/te7tycmpiutw4kia 'opendkim-testkey' shows that the key is OK. The messages in the example comes from yahoo.com, however other messages from yahoo.com, ones that are not sent through the mailing list, are properly validated. The failure is not specific to yahoo.com since a couple of other messages from other domains, sent though the mailing list, also failed DKIM validation. However, the vast majority of the messages from the list properly pass DKIM validation. From what I have read, mailing lists in general do not play very well with DKIM or SPF and the Dovecot mailing list also had some issues with this in the past. With the Dovecot mailing list, I am a bit curious about why the vast majority of the messages from the list pass DKIM validation while a couple of them fail. Does the Dovecot mailing list software alter the message in a way that causes the failure? Or is there something else going on? Any thoughts? Cheers.

ZLIB/ZSTD Compressed MBOX in Maildir++ layout
by Pedro Ribeiro 28 Jun '21

28 Jun '21

Hello everyone! Our archive namespace is kept in MBOX format with Maildir++ layout due to: * Need to have the email from all users/folders self contained (our base namespace uses MDBOX with single instance storage of attachments) * MBOX/FS layout isn't supported because some folders have messages and subfolders. I'm trying to compress that namespace using zstd/gzip following the informations from Dovecot documentation about the zlib plugin but when the (MBOX/Maildir++) compress and become with .zst/.zstd/.gz suffix (both tested) the system can't read the mailboxes and incorrectly reports the suffix (.zstd/.gz) as a subfolder name (following the Maildir++ file structure). Is there any way to make the MBOX/Maildir++ compatible with the zlib compression? Using Dovecot 2.3.14 on Debian10 Regards. -- Best regards, =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Pedro Ribeiro Politécnico de Lisboa, Serviços da Presidência Departamento de Sistemas de Informação e Comunicações Phone: +351 210 464 700 (general) / VoIP: 80100 Helpdesk: helpdesk(a)net.ipl.pt / https://www.net.ipl.pt =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

[BUG] doveadm / mail-crypt: Error when setting new password for a user key
by Kevin N. 28 Jun '21

28 Jun '21

Dovecot version: 2.3.14 When setting a new password for a user key you have the option to prompt the user for the old and the new password, instead of providing them as parameters (using -N and -O instead of -n and -o). However, running: doveadm mailbox cryptokey password -u user@domain -N -O produces an error instead of prompting the user for the old and the new password. The error is: password: option requires an argument -- 'O' You can work around this by providing a dummy input for -O which seems to be properly ignored in the end, but it would be nice to not throw any errors since -O should not expect an argument. Regards.

Support client_id variable expansion
by Eirik Rye 28 Jun '21

28 Jun '21

Hello, We are using imap_id_log='*' (and imap_id_retain=yes) to log user client information to the dovecot logs, and this information is aggregated to give us extra debugging information for customer support. However, as some clients send the ID information pre-login and others send it post-login, the aggregation logic is needlessly complex as we need to correlate the session IDs of the pre-login ID messages in order to determine the correct user. Hoping to simplify this, I wanted to log the client_id variable on logout, in imap_logout_format: imap_logout_format = in=%i out=%o deleted=%{deleted} expunged=%{expunged} trashed=%{trashed} hdr_count=%{fetch_hdr_count} hdr_bytes=%{fetch_hdr_bytes} body_count=%{fetch_body_count} body_bytes=%{fetch_body_bytes} client_id="%{client_id}" However, this only results in the following log being printed: client_id="UNSUPPORTED_VARIABLE_client_id" While examining the source code (login-common/client-common.c), it seems like this could be trivially supported by adding `client_id` to the `login_var_expand_empty_tab` struct, and adding the relevant code to populate this variable to `get_var_expand_table(struct client *client)`. I am willing to write a pull request for this, unless I am missing some obvious reason why expansion of the client's `client_id` field is not supported in the first place? - Eirik
