Crash in dovecot snippet when using imapc
by John van der Kamp 03 Sep '25

03 Sep '25

Hello, I've found a crash in a very specific setup. A dovecot server with imapc connection needs to receive an email with no body contents for the intent of generating a preview/snippet. It crashes somewhere deep in the jungle of istream and snapshots. I've included a script which sets up the systems to reproduce the crash. I've tested this with several versions. 2.3.16 doesn't seem to be affected, but 2.3.20 and 2.3.21 are affect. For me it produces a traceback like this, using the ubuntu version from here: https://packages.ubuntu.com/noble/dovecot-core (gdb) bt #0 __pthread_kill_implementation (no_tid=0, signo=6, threadid=140530132887360) at ./nptl/pthread_kill.c:44 #1 __pthread_kill_internal (signo=6, threadid=140530132887360) at ./nptl/pthread_kill.c:78 #2 __GI___pthread_kill (threadid=140530132887360, signo=signo@entry=6) at ./nptl/pthread_kill.c:89 #3 0x00007fcfb8842476 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #4 0x00007fcfb88287f3 in __GI_abort () at ./stdlib/abort.c:79 #5 0x00007fcfb8b37fe5 in default_fatal_finish (status=0, type=LOG_TYPE_PANIC) at ../lib/failures.c:465 #6 fatal_handler_real (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:477 #7 0x00007fcfb8be50d7 in i_internal_fatal_handler (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:879 #8 0x00007fcfb8b37eea in i_panic (format=0x7fcfb8c29020 "file %s: line %d (%s): assertion failed: (%s)") at ../lib/failures.c:530 #9 0x00007fcfb8b3387b in i_stream_header_filter_snapshot_free (_snapshot=<optimized out>) at ../lib-mail/istream-header-filter.c:663 #10 i_stream_header_filter_snapshot_free (_snapshot=0x55dabe297a60) at ../lib-mail/istream-header-filter.c:655 #11 0x00007fcfb8bf25ac in i_stream_snapshot_free (_snapshot=_snapshot@entry=0x55dabe29b0d0) at ../lib/istream.c:253 #12 0x00007fcfb8bf2654 in i_stream_unref (stream=0x7ffc16cc7fa0) at ../lib/istream.c:66 #13 0x00007fcfb8d96baa in index_mail_write_body_snippet (mail=0x55dabe292058) at index/index-mail.c:1151 #14 0x00007fcfb8d97e48 in index_mail_parse_bodystructure (mail=0x55dabe292058, field=MAIL_CACHE_BODY_SNIPPET) at index/index-mail.c:1551 #15 0x00007fcfb8d97fe2 in index_mail_fetch_body_snippet (value_r=0x7ffc16cc8050, mail=0x55dabe292058) at index/index-mail.c:1602 #16 index_mail_get_special (_mail=0x55dabe292058, field=<optimized out>, value_r=0x7ffc16cc8050) at index/index-mail.c:1730 #17 0x00007fcfb8d16ffe in mail_get_special (mail=mail@entry=0x55dabe292058, field=field@entry=MAIL_FETCH_BODY_SNIPPET, value_r=value_r@entry=0x7ffc16cc8050) at /home/ubuntu/dovecot/new/dovecot-2.3.21+dfsg1/src/lib-storage/mail.c:418 #18 0x000055dabc52645c in fetch_snippet (ctx=0x55dabe26e050, mail=0x55dabe292058, preview=0x55dabe28f1f8) at ./src/imap/imap-fetch-body.c:615 #19 0x000055dabc52b5cc in imap_fetch_more_int (ctx=0x55dabe26e050, cancel=false) at ./src/imap/imap-fetch.c:562 #20 0x000055dabc52b8ad in imap_fetch_more (ctx=0x55dabe26e050, cmd=0x55dabe26de98) at ./src/imap/imap-fetch.c:617 #21 0x000055dabc51fd07 in cmd_fetch (cmd=0x55dabe26de98) at ./src/imap/cmd-fetch.c:382 #22 0x000055dabc528af4 in command_exec (cmd=0x55dabe26de98) at ./src/imap/imap-commands.c:201 #23 0x000055dabc52e9e2 in client_command_input (cmd=<optimized out>) at ./src/imap/imap-client.c:1237 #24 0x000055dabc52ea96 in client_command_input (cmd=<optimized out>) at ./src/imap/imap-client.c:1307 #25 0x000055dabc52eeed in client_handle_next_command (remove_io_r=<synthetic pointer>, client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1349 #26 client_handle_input (client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1363 #27 0x000055dabc52f2c4 in client_input (client=0x55dabe26d2c8) at ./src/imap/imap-client.c:1407 #28 0x00007fcfb8bfe27d in io_loop_call_io (io=0x55dabe26e660) at ../lib/ioloop.c:737 #29 0x00007fcfb8bff81a in io_loop_handler_run_internal (ioloop=0x55dabe243fd0) at ../lib/ioloop-epoll.c:222 #30 0x00007fcfb8bff8d4 in io_loop_handler_run (ioloop=0x55dabe243fd0) at ../lib/ioloop.c:789 #31 0x00007fcfb8bffa90 in io_loop_run (ioloop=0x55dabe243fd0) at ../lib/ioloop.c:762 #32 0x00007fcfb8b6ce57 in master_service_run (service=0x55dabe243e20, callback=callback@entry=0x55dabc533210 <client_connected>) at ../lib-master/master-service.c:878 #33 0x000055dabc51ad37 in main (argc=<optimized out>, argv=<optimized out>) at ./src/imap/main.c:575 John Hello, I've found a crash in a very specific setup.

Missing IMAP METADATA Plugin
by Adam Miller 23 Aug '25

23 Aug '25

OS: Ubuntu 22.04.1 Dovecot: 2.3.16 (7e2e900c1a) When trying to enable the “imap_metadata” plugin, I get the following error: Plugin 'imap_metadata' not found from directory /usr/lib/dovecot/modules I have searched high and low via Google, StackOverflow and even ChatGPT (haha) but I cannot seem to find the package that provides the plugin. Does Dovecot have to be built from source for this plugin to be included? Any help is appreciated. Thank you!

Quota wrongfully reported as exceeded on shared mailbox
by adminkram＠tripelspark.de 07 May '25

07 May '25

Hi, I've been scratching my head without luck with the following problem: I've shared a mailbox from one user "COMPANY" to another user "JOE". Both users have quotas and both quotas are less than 50% used. When the user JOE tries to post a message into the shared folder, dovecot complains that the user would be over quota: bash# /usr/lib/dovecot/imap -u JOE 1 append shared/COMPANY/Sent/JOE {10} a NO [OVERQUOTA] Quota exceeded (mailbox for user is full) (0.057 + 0.000 + 0.057 secs). However, nobody is over quota: bash# doveadm quota get -u COMPANY Quota name Type Value Limit % User quota STORAGE 4754996 10485760 45 User quota MESSAGE 33695 - 0 bash# doveadm quota get -u JOE Quota name Type Value Limit % User quota STORAGE 14 1048576 0 User quota MESSAGE 3 - 0 Some more infos: 1. Dovecot-2.3.21 (+Debian updates) 2.3.21 (47349e2482) (NOTE: dovecot.org/mailing-lists says: Use dovecot –version to get it. The command is dovecot --version, though!) 2. I've performed "doveadm quota recalc" on both users, no change. 3. I've checked sharing ACL permissions, if I give just "l" permission, the response will be "NO [NOPERM] Permission denied". It does not seem to be an ACL permission reported wrongly. 4. I've tried increasing the quota size beyond reason (100 Gbytes for JOE), no change. 5. I've restarted dovecot after each change. 6. When trying to move a message into the shared Sent/joe folder in Thunderbird, same problem happens, Thunderbird displays the over quota message. Thunderbird cannot display the quota info for the shared folder, though. 7. I tried to enable rawlog (rawlog_dir in protocol imap). It does nothing helpful. It logs the manual commands from my pre-auth sessions (imap -u JOE) but it will stubbornly not log any commands issued by Thunderbird. ?! Any idea how to further debug this or what could be wrong? Thank you, Wolfgang

Stats-writer permission denied
by Ken Wright 15 Apr '25

15 Apr '25

I've got a new Dovecot error (well, new to me, at least)! I ran tail /var/log/mail.err and got the following: net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission denied I checked the file, and it's owned by www-data and the www-data group, with read and write permissions for owner and group... just like I have specified in /etc/dovecot/conf.d/10-master.conf. I can't understand why permission is denied when the file permissions appear to be correct. Can anyone shed any light on this for me? Ubuntu 20.04 Dovecot 2.3.7.2 Ken

Bug: Logout counters reset after recreating hibernated process
by Eirik Rye 12 Mar '25

12 Mar '25

Hello, # dovecot --version 2.3.20 (80a5ac675d) When using hibernation (`imap_hibernate_timeout = 10s`), counters such as deleted/expunged messages, appear to be reset after the user process is recreated. Steps to reproduce: 1. Configure IMAP hibernation 2. Login with IMAP client 3. Delete+expunge a message 4. IDLE, and wait 10s for process to be hibernated 5. Unhibernate process (`DONE`), and log out 6. Observe the logged line: 2023-09-05T17:36:26+0200 imap(<redacted>)<776933><jA2nYJ4EPdcqAVtAAADwAAutur4AAAAB>: Info: Disconnected: Logged out in=9 out=88 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 The expected output is "deleted=1 expunged=1", not "deleted=0 expunged=0". If you follow the steps above, but skip the IDLE/hibernate step, the output is as expected. Interestingly, if the client is disconnected during hibernation (without recreating the process), the output from `imap-hibernate` is still as expected: 2023-09-05T17:45:15+0200 imap-hibernate(<redacted>)<770540><0qE0gJ4Emt8qAVtAAADwAAutur4AAAAB>: Info: Disconnected: Connection closed in=97 out=1020 deleted=1 expunged=1 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 This leads me to believe the counters are lost during process recreation, not during hibernation. This is an issue as customers will often come to us asking why messages have disappeared in their inbox, or asking for help to identify which client is expunging messages. Right now, this information is lost if hibernation is used and the client is hibernated after expunging. Best regards, Eirik Rye
