Dovecot 2.3.15 compilation fails
by Andreas M. Kirchwitz 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.
