replicator: Panic: data stack: Out of memory when allocating 268435496 bytes
by Gerben Wierda 06 Dec '23

06 Dec '23

One step further in my quest to create a replacement mail server. I now have my old mail server (2.3.19.1, macOS + MacPorts) and my new (2.3.20, Alpine Linux, Docker, apk package). When I turn on replication it works, but, after a while I see: Jan 06 00:50:31 replicator: Panic: data stack: Out of memory when allocating 268435496 bytes Jan 06 00:50:32 replicator: Fatal: master: service(replicator): child 133 killed with signal 6 (core dumped) Jan 06 00:50:32 lmtp(pid 195 user sysbh): Warning: replication(sysbh): Sync failure: Jan 06 00:50:32 lmtp(pid 195 user sysbh): Warning: replication(sysbh): Remote sent invalid input: - I've removed synchronous operation for now (found a message on the net suggesting that) but is this known and what does it mean?

bug report: lmtp fails on root-squashed NFS filesystem
by Anne Bennett 09 Oct '23

09 Oct '23

Hi, all. I'm trying to set up Postfix with dovecot LTMP delivery on a host where the user files (/var/spool/mail as well as home directories) are on NFS filesystems, which are exported root-squashed to the mail server. I definitely don't want to give the mail server root permissions on the user files. LMTP delivery fails with this logged message (e.g.): Nov 16 17:51:36 lust dovecot: lmtp(anne)<16830><mkkzEPg1lGG+QQAAs/mAJw>: msgid=<202111162229.1AGMTfAO024765(a)vindemiatrix.encs.concordia.ca>: save failed to INBOX: Read-only mbox I found this posting where someone else had a similar problem and traced it in some detail back in 2019: https://dovecot.org/list/dovecot/2019-February/114611.html but apparently no one answered the fellow. In order to check that this is indeed the same problem, I temporarily changed the INBOX definition to make it write into /var/tmp/ (on a local filesystem), and delivery worked. I then temporarily changed the INBOX definition to make it write into an NFS filesystem with root NOT squashed, and again it worked (after I chmodded the directory to 1777 to allow any user to create a file). I believe that the person who wrote the above posting is correct: at some point, file access is (incorrectly) checked as root instead of as the target user. This is a bit of a showstopper for me. Any plans to address this? I attach the output of "dovecot -n", fwiw, but I don't think that this is a configuration problem...

Compression: all or nothing?
by Alex King 03 Oct '23

03 Oct '23

Using 2.3.13 (89f716dc2) (debian package), with mdbox storage. I considering adding the zlib plugin. I understand that reading mail can cope with either compressed or uncompressed mailboxes. I'm wondering if I can leave the main storage uncompressed, while having the alternate storage compressed. There does not seem to be a way to configure this, from https://doc.dovecot.org/settings/plugin/zlib-plugin/ it seems compression (on saving emails) is an all-or-nothing option? Can I leave zlib_save unset in my main configuration, and have doveadm use some alternate configuration with zlib_save set? It doesn't look hopeful because I don't see the ability to use a different config at https://wiki.dovecot.org/Tools/Doveadm/Altmove. Perhaps I would need multiple copies of the daemon running? Or is it better just to compress everything? I plan to store older mails (perhaps 3months+) in the alternative storage, and was thinking it would be nice to have those compressed, while I don't need to compress the main store. Any feedback welcome. Thanks, Alex

ACL management from SQL
by cyril.leclerc＠mantiq.com 14 Sep '23

14 Sep '23

Hello, we are facing issue, we manage the shared folder from SQL table, but it was never working as we have to manage acl permission from the server itself, we want to manage permissions (read or write) from the same application we can share user mailbox but it is written in dovecot documentation that is not supported now, we tried to find a mail client that could manage it at least, but only thunderbird was able to do it (but in version 60) and not more today. We saw that roundcube could handle it but we use rainloop. 1. It is really not possible at all to manage acl permissions fron SQL like the shared box itself ? 2. I tried to set acl permissions from old version of thunderbird, when i made modification it tried to update the sharedbox table, i did not see the query executed but as we were working on a view, the update failed. Do you know what it tried to do ?

auth: Panic: file oauth2-request.c assertion failed
by Urban Loesch 05 Sep '23

05 Sep '23

Hi, I'm running a postfix smtp relay server on which users are getting authenticated trough sasl via the dovecot authentication service. This works without problems. Recently I extended my configuration to authenticate users with the PLAIN mechanism against Azure AD B2C with oauth2 in the future. Important to mention is that currently no users are stored in Azure B2C. I only prepared the hole configuration and authentiucation falls back to mysql database. Now sometimes I get the error below in my logs (not permanently): ...

Dovecot director and backend on same server
by Michael Cassaniti 29 Aug '23

29 Aug '23

Hi, I'm attempting to run both the director and the backend under the same configuration on the same server. When I run doveadm director map I don't get any output. I have a shared file system between servers and clients can access any server. I was running without a director in front and seeing index corruption so I'm now attempting to use a director.

Dovecot, mail_crypt, global keys, permissions
by David Mehler 28 Aug '23

28 Aug '23

Hello, I'm using Dovecot v2.3 with the mail_crypt plugin and global keys. I am seeing this error immediately after imap login then after this error imap logs out. I'm hoping this is a simple permissions problem and the key can not be read rather than an underlying configuration issue. I do not know what this UID 5395 refers to. 2023-08-11T04:14:14.539308-04:00 hostname dovecot: imap(username(a)domain.org)<492738><zO4WTKECnvRoDWll>: Error: Mailbox INBOX: UID=5395: read() failed: read(/var/mail/mailboxes/domain.org/username/mail/mailboxes/INBOX/dbox-Mail… failed: Private key not available: mailbox_attribute_get(INBOX, /priv/vendor/vendor.dovecot/pvt/crypt/privkeys/e9f195fe9fd1953d08e815ba6fda9b6c5ae1ed692c9adade2f958c322552cbb0) failed: Mailbox attributes not enabled (FETCH BODY[HEADER]) #ls -ld crypt drwxr-xr-x 2 root root 4096 Jul 25 08:52 crypt/ # cd crypt #ls -l * -r-------- 1 root root 241 Jul 25 15:43 master.key -rw-r--r-- 1 root root 178 Jul 25 15:43 master.pub Thanks.

Bug - doveadm backup out-of-memory kill/crash when no separators set
by James Harrison 26 Aug '23

26 Aug '23

Hi, I hit a fun issue with doveadm when migrating from dovecot 2.2.36 (1f10bfa63) to 2.3.19.1 (9b53102964) (CentOS 7 to Debian 12). When running doveadm -v -D backup -R -u "user@name" tcp:localhost:1234, I found that the first sync would always work, but subsequent runs of the command would cause doveadm to reach a subfolder (Archives/2008 in the example below) and then silently mmap() increasing powers of 2 before the OOM killer finally got it. Deleting the source folder caused it to remain stuck on the same folder, but for the deletion event. I switched memory overcommit off to force a crash, and got a gdb backtrace: #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 #1 0x00007ffff786bd9f in __pthread_kill_internal (signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:78 #2 0x00007ffff781cf32 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #3 0x00007ffff7807472 in __GI_abort () at ./stdlib/abort.c:79 #4 0x00007ffff7b4ffae in default_fatal_finish (status=0, type=LOG_TYPE_PANIC) at ../lib/failures.c:465 #5 fatal_handler_real (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:477 #6 0x00007ffff7bfa081 in default_fatal_handler (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:485 #7 0x00007ffff7b5017c in i_panic (format=0x7ffff7c5d748 "data stack: Out of memory when allocating %zu bytes") at ../lib/failures.c:530 #8 0x00007ffff7b4f67f in mem_block_alloc (min_size=min_size@entry=16) at ../lib/data-stack.c:386 #9 0x00007ffff7bf8b60 in t_malloc_real (size=<optimized out>, permanent=<optimized out>) at ../lib/data-stack.c:492 #10 0x00007ffff7c348f1 in t_strdup_until (start=start@entry=0x55555565f440, end=end@entry=0x55555565f448) at ../lib/strfuncs.c:270 #11 0x00005555555adc62 in convert_name_to_remote_sep (name=0x55555565f440 "Archives/2008", tree=0x55555564e188) at dsync/dsync-mailbox-tree.c:270 #12 dsync_mailbox_tree_build_name128_remotesep_hash (tree=0x55555564e188) at dsync/dsync-mailbox-tree.c:315 #13 dsync_mailbox_tree_find_delete (tree=0x55555564e188, del=0x5555556469f0) at dsync/dsync-mailbox-tree.c:405 #14 0x00005555555a4195 in dsync_brain_mailbox_tree_add_delete (tree=0x55555564e188, other_tree=0x55555564f5f8, other_del=0x5555556469f0, node_r=0x7fffffffe350, status_r=0x7fffffffe348) at dsync/dsync-brain-mailbox-tree.c:504 #15 0x00005555555a44cd in dsync_brain_recv_mailbox_tree_deletes (brain=0x55555564b2d8) at dsync/dsync-brain-mailbox-tree.c:590 #16 0x00005555555a5365 in dsync_brain_run_real (brain=brain@entry=0x55555564b2d8, changed_r=changed_r@entry=0x7fffffffe453) at dsync/dsync-brain.c:709 #17 0x00005555555a59f9 in dsync_brain_run (changed_r=0x7fffffffe453, brain=0x55555564b2d8) at dsync/dsync-brain.c:752 #18 dsync_brain_run (changed_r=0x7fffffffe453, brain=0x55555564b2d8) at dsync/dsync-brain.c:740 #19 dsync_brain_run_io (context=<optimized out>) at dsync/dsync-brain.c:113 #20 dsync_brain_run_io (context=0x55555564b2d8) at dsync/dsync-brain.c:100 #21 0x00005555555b23df in dsync_ibc_stream_input (ibc=0x555555646720) at dsync/dsync-ibc-stream.c:232 #22 0x00007ffff7c11cd9 in io_loop_call_io (io=0x5555556418f0) at ../lib/ioloop.c:737 #23 0x00007ffff7c13aa2 in io_loop_handler_run_internal (ioloop=ioloop@entry=0x55555560bf40) at ../lib/ioloop-epoll.c:222 #24 0x00007ffff7c13b50 in io_loop_handler_run (ioloop=ioloop@entry=0x55555560bf40) at ../lib/ioloop.c:789 #25 0x00007ffff7c13d10 in io_loop_run (ioloop=0x55555560bf40) at ../lib/ioloop.c:762 #26 0x000055555558b22e in cmd_dsync_run_remote (user=0x555555637248) at ./src/doveadm/doveadm-dsync.c:543 #27 cmd_dsync_run (_ctx=0x55555561f288, user=0x555555637248) at ./src/doveadm/doveadm-dsync.c:750 #28 0x000055555558bd12 in doveadm_mail_next_user (ctx=0x55555561f288, error_r=0x7fffffffe818) at ./src/doveadm/doveadm-mail.c:464 #29 0x000055555558cf45 in doveadm_mail_cmd_exec (wildcard_user=0x0, ctx=0x55555561f288) at ./src/doveadm/doveadm-mail.c:659 #30 doveadm_cmd_ver2_to_mail_cmd_wrapper (cctx=0x7fffffffe970) at ./src/doveadm/doveadm-mail.c:988 #31 0x0000555555597622 in doveadm_cmd_run_ver2 (argc=5, argv=0x55555560ba38, cctx=cctx@entry=0x7fffffffe970) at ./src/doveadm/doveadm-cmd.c:465 #32 0x0000555555597697 in doveadm_cmd_try_run_ver2 (cmd_name=<optimized out>, argc=<optimized out>, argv=<optimized out>, cctx=0x7fffffffe970) at ./src/doveadm/doveadm-cmd.c:363 #33 0x000055555557919a in main (argc=<optimized out>, argv=<optimized out>) at ./src/doveadm/doveadm.c:361 Neither server had a separator set in the inbox namespace. Having identified the convert_name_to_remote_sep function as the likely trigger point I set the separator to / on both ends, and doveadm backup now runs without issue. Can provide config if helpful but I think probably irrelevant to this one - the namespace config is the default other than the separator item. May be worth mentioning that having the separator set can avoid this condition in the doveadm backup docs - this took me a while to figure out! -- Cheers, James Harrison
