Hi, when I check "doveadm log errors" I found some fatal error repeated many times by around the same users - Panic: file message-part-data.c May 31 21:03:46 pop08 dovecot: imap(user1(a)email.com) session=<tON64qTDu8OXFBVM>: Error: Mailbox INBOX: UID=3454: imap_bodystructure_parse() failed: message_part lines doesn't match lines in BODYSTRUCTURE May 31 21:03:46 pop08 dovecot: imap(user1(a)email.com) session=<tON64qTDu8OXFBVM>: Error: Mailbox INBOX: UID=3454: imap_bodystructure_parse() failed: message_part lines doesn't match lines in BODYSTRUCTURE May 31 21:03:46 pop08 dovecot: imap(user1(a)email.com) session=<tON64qTDu8OXFBVM>: Panic: file message-part-data.c: line 579 (message_part_is_attachment): assertion failed: (data != NULL) May 31 21:03:46 pop08 dovecot: imap(user1(a)email.com) session=<tON64qTDu8OXFBVM>: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f294d7fdac2] -> /usr/lib64/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f294d7fdbce] -> /usr/lib64/dovecot/libdovecot.so.0(+0xf3cde) [0x7f294d80acde] -> /usr/lib64/dovecot/libdovecot.so.0(+0xf3d81) [0x7f294d80ad81] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f294d75c25a] -> /usr/lib64/dovecot/libdovecot.so.0(+0xd377d) [0x7f294d7ea77d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x3ecbc) [0x7f294db0ccbc] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x3eca4) [0x7f294db0cca4] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_set_attachment_keywords+0xe7) [0x7f294db0dd17] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xc15a4) [0x7f294db8f5a4] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0xc190e) [0x7f294db8f90e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x332) [0x7f294db8fd32] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x77428) [0x7f294db45428] -> /usr/lib64/dovecot/libdovecot-storage.soindex-mail-headers.c.0(mail_get_hdr_stream_because+0x5b) [0x7f294db0d6ab] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_get_header_stream+0x18a) [0x7f294db8d68a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_get_header_stream+0x53) [0x7f294db0d493] -> /usr/lib64/dovecot/libdovecot-storage.so.0(imap_msgpart_open+0x5aa) [0x7f294dbd20aa] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](+0x235ae) [0x5568ba7fd5ae] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](+0x210ac) [0x5568ba7fb0ac] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](imap_fetch_more+0x35) [0x5568ba7fc6e5] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](cmd_fetch+0x34d) [0x5568ba7ec7ed] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](command_exec+0x64) [0x5568ba7f9614] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](+0x1d502) [0x5568ba7f7502] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](+0x1d591) [0x5568ba7f7591] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](+0x1d759) [0x5568ba7f7759] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](client_handle_input+0x205) [0x5568ba7f7a15] -> dovecot/imap [user1(a)email.com 18.123.45.76 UID FETCH](client_input+0x79) [0x5568ba7f7ff9] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x65) [0x7f294d822f45] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x12b) [0x7f294d8248fb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x59) [0x7f294d823049] May 31 21:03:46 pop08 dovecot: imap(user1(a)email.com) session=<tON64qTDu8OXFBVM>: Fatal: master: service(imap): child 21483 killed with signal 6 (core dumps disabled -

maildirfolder file created in maildir root during auto-creation with 2.3.4.1 but not 2.2.27
by Christian Balzer 02 Sep '21

02 Sep '21

Hello, as the tin says. I have several servers running 2.2.27 (Debian stretch) and am adding new ones with 2.3.4.1 (Debian buster). The configs were upgraded where needed but neither 10-mail.conf nor 15-mailboxes.conf were changed. 15-mailboxes is all commented out (I guess the default is auto-create, which isn't documented anywhere I could find) and the only non-comments in 10-mail.conf are --- mail_location = maildir:%h mail_privileged_group = mail --- So yes, no namespaces are explicitly defined/declared. The 2.3.4.1 version wrongly creates a maildirfolder file in the home directory (maildir root), preventing exim from correctly creating/using maildirsize. a) Is this expected behavior and can it be changed? b) How can I disable inbox auto-creation if a) doesn't pan out? Thanks, Christian -- Christian Balzer Network/Systems Engineer chibi(a)gol.com Rakuten Mobile Inc.

BUG REPORT: MAIL-CRYPT plugin: doveadm mailbox cryptokey -O option
by ean365 17 Aug '21

17 Aug '21

Aki: I have identified a bug in the "*-O*" option of "*doveadm mailbox cryptokey password*" plugin command -- it is expecting an argument, but it is supposed to be a boolean option. I have also identified the (simple) fix to the source on github... /I am a dovecot community noob, so please forgive me if this has already been identified... (if so, I hope it gets fixed soon)... / The "-O" option in *struct doveadm_cmd_mcp_key_password* is set to expect a *STR* parameter, but it should be *BOOL*. See line 1027 in plugins/mail-crypt/doveadm-mail-crypt.c of master branch... Currently: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_STR, **0**) *Should be: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_BOOL, **0**)* Workaround is to specify *-O* last on command line with a dummy argument, like this: *doveadm mailbox cryptokey password -N -O ""* Also, a quick question and suggestion -- Why does the *doveadm mailbox cryptokey password* command not ask for a new password twice, with a check that both entries must match before the password is changed? The last thing we would want is to type something wrong accidentally, and change the new password to something unknown -- rendering encrypted email unrecoverable. I would like to suggest that the code in *cmd_mcp_key_password_run* be amended to include verifying password entry twice. (I am writing a simple addition to postfixadmin that changes the user's mail-crypt password whenever they use postfixadmin to change their login password. It calls *doveadm* to change the keys. I came across this bug while working through this.) Thanks for all your help! Eric **

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

LMTP with hardlinks ?
by Vladislav Kurz 16 Jun '21

16 Jun '21

Hello, I'm looking for deduplication of mails via hardlinks during delivery. I.e. a mail that is sent to multiple recipients (to, cc, bcc) should be stored only once. I did some search and found only some non-complete information. dovecot-lda has a "-p path" option that does the delivery using symlinks if possible (i.e. same uid/gid and same filesystem). This is working by hand, but could not find any hints how to use this with postfix. Found only suggestion of a wrapper, that was probably never implemented - in this thread: https://dovecot.org/pipermail/dovecot/2008-June/031158.html In this message: https://dovecot.org/list/dovecot/2013-February/088540.html there is statement that: LMTP always delivers the mail to the first user. Then it tries to copy the first mail to the second user, because in some setups this can be done using hard links. I was not able to get this in my setup, and I'd like to know if this statement is really true. I have all mail in /var/vmail, all owned by vmail user, but still mail delivered to multiple users is duplicated. If this is really supposed to make hardlinks (which would be great), is there any way to debug it? E.g. see if the hardlink was attempted but failed for some reason, or if the message was delivered in the same LMTP session ? -- Best Regards Vladislav Kurz

Dovecot Subfolder Always Uses dot separator with mdbox
by Steven Smith 09 Jun '21

09 Jun '21

I’m trying to configure dovecot to use mailbox subfolders that look like both foo/bar on the IMAP client and the filesystem. But the subfolders created all look like foo.bar, not foo/bar with a proper nesting structure. This also happens when the folder ‘bar’ is moved into the folder ‘foo’—A new folder `foo.bar’ is created. I believe that i’m following the configuration rules at https://wiki.dovecot.org/MailboxFormat/Maildir#Maildir_and_filesystems and https://wiki.dovecot.org/MailLocation/Maildir. This issue happens whether I set separator to its default, ‘.’, or ‘/’: > mail_location = mdbox:/private/var/mail/tld.hostname.mail/%Ln/mdbox:LAYOUT=fs > namespace inbox { > … > separator = / > … > } The IMAP client is macOS Mail.app version 14.0. I’d greatly appreciate any help or pointers to fix this configuration issue. dovecot -n > # 2.3.13 (): /opt/local/etc/dovecot/dovecot.conf > # Pigeonhole version 0.5.13 () > # OS: Darwin 20.4.0 x86_64 apfs > #

Panic on indexer-worker and Dovecot stop to search on Solr
by Alessio Cecchi 03 Jun '21

03 Jun '21

Hi, I have setup on a (little busy) Dovecot server FTS with Solr and Virtual folder to enable "search in all folders" for users. All works fine until for some users the indexer-worker process crash. After this crash Dovecot stop to query Solr for new search in BODY, returning SERVERBUG, for all users on the server and only with a dovecot restart users can search in BODY again. Before the dovecot restart I can see that on Solr server no query from dovecot arriving anymore (for SEARCH BODY because SEARCH in FROM/TO/SUBJECT still works fine) Dovecot version is 2.3.14 (from RPM) and Apache Solr si 7.7.3. Here is the error found in the log: May 31 14:58:13 Panic: indexer-worker(user(a)email.com) session=<VA0oxZ/DXtG5Ydlx:0KzOIkLdtGDSawAAxbYlJw>: file http-client-request.c: line 1240 (http_client_request_send_more): assertion failed: (req->payload_input != NULL) May 31 14:58:13 Error: indexer-worker(user(a)email.com) session=<VA0oxZ/DXtG5Ydlx:0KzOIkLdtGDSawAAxbYlJw>: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f3d91b2cac2] -> /usr/lib64/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f3d91b2cbce] -> /usr/lib64/dovecot/libdovecot.so.0(+0xf3cde) [0x7f3d91b39cde] -> /usr/lib64/dovecot/libdovecot.so.0(+0xf3d81) [0x7f3d91b39d81] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3d91a8b25a] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_request_send_more+0x3dd) [0x7f3d91ad39ad] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_connection_output+0xf1) [0x7f3d91ad8101] -> /usr/lib64/dovecot/libdovecot.so.0(+0x11d2b0) [0x7f3d91b632b0] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x65) [0x7f3d91b51f45] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x12b) [0x7f3d91b538fb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x59) [0x7f3d91b52049] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f3d91b52288] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_wait+0xcd) [0x7f3d91ae120d] -> /usr/lib64/dovecot/lib21_fts_solr_plugin.so(solr_connection_select+0xe4) [0x7f3d8fca1174] -> /usr/lib64/dovecot/lib21_fts_solr_plugin.so(+0x45d4) [0x7f3d8fc9d5d4] -> /usr/lib64/dovecot/lib20_fts_plugin.so(fts_backend_get_last_uid+0x6e) [0x7f3d90e103fe] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0xf952) [0x7f3d90e16952] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0x10ef6) [0x7f3d90e17ef6] -> /usr/lib64/dovecot/lib20_virtual_plugin.so(+0x966a) [0x7f3d90bfc66a] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0x10ba6) [0x7f3d90e17ba6] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_precache+0x2e) [0x7f3d91e3cb0e] -> dovecot/indexer-worker [user(a)email.com Virtual/All - 5300/20832](+0x2924) [0x5648464be924] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x65) [0x7f3d91b51f45] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x12b) [0x7f3d91b538fb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x59) [0x7f3d91b52049] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f3d91b52288] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f3d91abcbb3] -> dovecot/indexer-worker [user(a)email.com Virtual/All - 5300/20832](main+0xd7) [0x5648464be1f7] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f3d9169a555] -> dovecot/indexer-worker [user(a)email.com Virtual/All - 5300/20832](+0x22ba) [0x5648464be2ba] May 31 14:58:13 Fatal: indexer-worker(user(a)email.com) session=<VA0oxZ/DXtG5Ydlx:0KzOIkLdtGDSawAAxbYlJw>: master: service(indexer-worker): child 27602 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) on Solr side I found this error log: org.apache.solr.common.SolrException: Early EOF at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:190) at org.apache.solr.handler.UpdateRequestHandler$1.load(UpdateRequestHandler.java:97) at org.apache.solr.handler.ContentStreamHandlerBase.handleRequestBody(ContentStreamHandlerBase.java:68) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:199) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2551) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:733) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:531) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:395) [...] and [com.ctc.wstx.exc.WstxLazyException] com.ctc.wstx.exc.WstxIOException: Early EOF at com.ctc.wstx.exc.WstxLazyException.throwLazily(WstxLazyException.java:45) at com.ctc.wstx.sr.StreamScanner.throwLazyError(StreamScanner.java:728) at com.ctc.wstx.sr.BasicStreamReader.safeFinishToken(BasicStreamReader.java:3678) at com.ctc.wstx.sr.BasicStreamReader.getText(BasicStreamReader.java:860) at org.apache.solr.handler.loader.XMLLoader.readDoc(XMLLoader.java:419) at org.apache.solr.handler.loader.XMLLoader.processUpdate(XMLLoader.java:260) at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:188) at org.apache.solr.handler.UpdateRequestHandler$1.load(UpdateRequestHandler.java:97) This is the relevant part of dovecot configuration: plugin { fts = solr fts_autoindex = yes fts_decoder = decode2text fts_enforced = body fts_index_timeout = 5s fts_solr = url=http://10.0.1.3:8983/solr/dovecot/ [...] } Is this an already know bug?

Dovecot Stats for Logwatch
by Plutocrat 03 Jun '21

03 Jun '21

Hi all, I run logwatch on a few servers and the script on there which parses the dovecot logs provides waaaaaay too much detail, and contains a bunch of stuff I'm not interested in. There's not much point in having a log summary if its 100Kb long! The one for exim is also terrible, but I've replaced that with eximstats, and a bit of bash scripting and have something I can work with. I might at some point look at replacing that too. Now to my question. I haven't found anything in the dovecot family which compares to eximstats. I was wondering if there possibly is a report tool, or a way of extracting stats from doveadm just for key metrics such as 'number of POP logins in the last 24 hours', number of failed passwords, etc. Things that might be interesting on a logwatch report. Or maybe someone has written a script already that can be used in logwatch in perl, python, bash, whatever. Any pointers, suggestions, or ideas for useful summary metrics to pull out of the logfiles are appreciated. I suspect I might end up writing one myself anyway, but I'm just keen to see what already exists, get the benefit of anyone else's experiences in this matter before I start. P.

debugging file permissions wrong
by Laura Steynes 02 Jun '21

02 Jun '21

Hi, In trying to debug a strange error where client can't login, I enabled all the usual debug settings, this is all good, it works for imap and pop3 fine, but the problem is when used with dovecot's LDA there is a nasty issue. the file created by debug_log_path in this case /var/log/dovecot/debug.log , this file created as root, again this is fine for nice logging of imap and pop3, but this causes postfix not to deliver mail, for write permission denied, LDA runs as vmail, all my sub sections like *_listener also = vmail and all my uid/gid settings are also to user/group vmail obviously you wont main log files to not be owned by vmail for case of security, so is there a way to set the ownership of the debug file - apart from the obvious of remembering 40 minutes later when you get alert of high mailq level to chown the file :) If there is no way, may the developers take this as a feature request please. Thanks Loz
