prohibit subfolders under INBOX
by dentar＠fnsheppard.com 20 May '25

20 May '25

I know this is a n00b question but I've done my diligence... Is there a way (Maildir not MBOX) to ONLY prohibit creation of folders under INBOX e.g. no INBOX.Fred allowed, but the user MAY create subfolders under other folders, e.g. Fred.Barney? We've discovered that when people create INBOX.anything it causes Outlook to go insane.

bug report: "Corrupted transaction log file" PLUS request for improvement of the documentation about mmap_disable
by Patrick Cernko 20 May '25

20 May '25

Hello Dovecot developers, hello list, since more than two years we had occasional log messages like this: Error: Mailbox INBOX: Corrupted transaction log file /IMAP/mail/mailboxes/USER/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log seq 45532: Unexpected garbage at EOF (sync_offset=4856) Mostly I had to repair the affected mailbox manually after such events. Luckily I could prevent any data corruptions by using the healthy mailbox from the replication partner. Those errors occurred rather seldom (once a month) but started get more often. At the end of last year, they occurred about once a week for 800 users with up to 200 folders. The reporting process was always different, like the indexer, imapd, lmtpd, replicator or doveadm (on cmdline). It was obviously some sort of race-condition between the different processes accessing the index. I did not see any hints how to reproduce it. At the beginning of this year I started to debug this issue by adding debugging log output to our productive system, mostly in lib-index. I was hoping to find the cause of the issue and maybe even provide a patch to fix this. But about 5 weeks ago, I discovered, that the error can be simply avoided by setting mmap_disable=yes. Since this change, the error did not occur again even with specific tests, that previously likely triggered the bug. That's where I stopped to debug further. We are running Dovecot in master-master mode using replication plugin behind a Dovecot director setup. The storage on the backends is provided by local disks on Linux with newest ZFS filesystem. We use mdbox storage and FTS. While testing I also checked ext4 instead of ZFS and different FTS backends without success. I can provide more information for the developers if you are interested! --------------------------------- About mmap_disable: The documentation only mentions, that you should set this to "yes" for SHARED filesystems (I don't think local ZFS or ext4 qualify for that). https://doc.dovecot.org/2.3/settings/core/#core_setting-mmap_disable On another page (https://doc.dovecot.org/2.3/admin_manual/mailbox_formats/#memory-mapping) it is mentioned, that "If mmap() is supported by your filesystem, it’s still not certain that it gives better performance. Try benchmarking to make sure." I also found an old mail from Timo (https://dovecot.org/list/dovecot/2011-December/079975.html) which lists 3 cases, where mmap_disable=yes is required or at least suggested. In only one case, he wrote "With local filesystems mmap_disable=no _should_ be faster." I did not do extensive benchmarks but I did not see any performance issues since we disabled mmap on our IMAP backends. So, I wonder, if it would not be better to switch the default for mmap_disable to YES: 1. There are configurations, where the current default might cause data corruption! 2. There are configurations, where disabling mmap is suggested. 3. Even on local storage, the performance benefits are unsure. 4. According to my observations, even on local storage, enabling mmap can cause data corruption. Changing the default to NO would protect users from accidental data corruption. Users that aim for maximum performance can still enable mmap and test if it improves performance. IMHO the documentation should mention, that even for local disks, mmap CAN cause data corruption (until the above mentioned bug is found and fixed).

Change the way folders are displayed via IMAP protocol

Hi. How can I patch the source code so that the server forces the list of all folders to be displayed in quotes? Or add the corresponding parameter to the configuration file? -- Best regards, Lafiel mailto:lafiel@elven.pw

Dovecot 3.21.1 -> 2.4.0 SegFault
by Cata S 19 May '25

19 May '25

Hi guys, There seems to be some issue with Dovecot deployed on alpine. More specifically, the dovecot.config file is not properly read. I have run some debugging and the SegFault is returned in the function below: #0 0x000055555556779b in config_parsed_get_setting () No symbol table info available. #1 0x0000555555563708 in config_dump_full () No symbol table info available. #2 0x000055555555c814 in main () No symbol table info available. This was also addressed by alpine here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/17050 Any idea what could be causing this? Thanks for looking into it, Cata

Users losing mail from their mailboxes
by Nikolaos Milas 18 May '25

18 May '25

Hello, We are on Dovecot 2.3.18. Some users are occasionally complaining that all mail vanishes from their inbox. However, we cannot find any indication of deletions or expunge in the log. One explanation could be that mail files are deleted externally (at the file system level), but I can't imagine what could cause such deletions. How would you suggest us to troubleshoot this further? We could enable "mail_debug = yes", but this would flood the logs and cause performance drop, and the issue is happening rarely. Any other ideas to troubleshoot these cases in the past (through logs) or monitor (whatever) for the future? (The config is listed at the end.) Thanks in advance.

Problem with Dovecot on a FIPS enabled system

For additional modules, the mail_plugin_dir parameter is ignored
by Lafiel 14 May '25

14 May '25

Hi. The NixOS distribution for Dovecot uses a patch that hardcodes the path to the plugins in `/etc/dovecot/modules`. The modules themselves are located at `/nix/store/z9kf4ri8sq9f3r510qsm59g1n6kfc7q6-dovecot-2.3.21.1/lib/dovecot`, the script creates symlinks in the `/etc/dovecot/modules` directory. The additional modules are loaded normally. Now I want to remove the patch. I added the parameter `“--with-moduledir=$(out)/etc/dovecot/modules”`, and the modules are located at path `/nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules`. In the configuration I added the parameter `mail_plugin_dir = /etc/dovecot/modules`. The main modules load fine, but the optional modules don't want to load: ``` Error: Plugin 'imap_sieve' not found from directory /nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules ``` For additional modules, the mail_plugin_dir parameter is ignored. Temporary solution - in src/config/config-parser.h file I replaced the line ``` #define CONFIG_MODULE_DIR MODULEDIR"/settings” ``` by ``` #define CONFIG_MODULE_DIR “/etc/dovecot/modules/settings” ``` -- Best regards, Lafiel mailto:lafiel@elven.pw
