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

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.

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] ```

I have a user failing to get mail , using TBird client is this due to his TBird email client backlevel TLS support ? I'm trying to find out his TBird version, might be an older TBird # dovecot --version 2.3.15 (0503334ab1) # egrep "ssl_protocols|ssl_min_protocol" /etc/dovecot/conf.d/10-ssl.conf #ssl_min_protocol = TLSv1.2 Jun 29 14:23:27 pop3-login: Info: Disconnected: Connection closed: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol (no auth attempts in 1 secs): user=<>, rip= 111.222.333.555, lip=ser.ver.ip.add, TLS handshaking: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol, session=<kZ6p99/FW9iTMgHi> Jun 29 14:23:54 pop3-login: Info: Disconnected: Connection closed: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol (no auth attempts in 1 secs): user=<>, rip= 111.222.333.555, lip=ser.ver.ip.add, TLS handshaking: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol, session=<Gq5G+d/Fu1STMgHi>

Increase FTS timeouts for slow(er) machines

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
