[Dovecot] A couple of dovecot issues I've noted recently...
by Dan Price 21 Jul '08

21 Jul '08

Timo et al., I haven't been reading the list in a while, but wanted to report back that we've transitioned to dovecot 1.0.15 and things look to be working very nicely. The platform is Solaris "Nevada" running on x86. I have been saving up a couple of issues to bring to your attention. On our server, we gather all core files, and so we get a good taste of the different things which are causing crashes. One problem which we see on an occasional basis is a crash in which the internal fatal error handling code goes horribly wrong. Here is an example. The complete stack trace is hugely long-- it appears that we recurse until we run totally out of stack. In gdb this looks like repeated calls like this: ... #14507 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b95d8 "\020") at failures.c:410 #14508 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14509 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14510 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14511 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14512 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14513 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14514 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b96d8 "\020") at failures.c:383 #14515 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b96d8 "\020") at failures.c:410 #14516 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14517 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14518 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14519 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14520 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14521 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14522 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b97d8 "\020") at failures.c:383 #14523 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b97d8 "\020") at failures.c:410 #14524 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14525 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14526 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14527 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14528 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14529 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14530 0x080b21f3 in internal_handler (log_type=70 'F', format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes", args=0x76b98d8 "\020") at failures.c:383 #14531 0x080b22b6 in i_internal_fatal_handler (status=83, fmt=0x0, args=0x76b98d8 "\020") at failures.c:410 #14532 0x080b1e1e in i_fatal_status (status=83, format=0x80cdd64 "mem_block_alloc(): Out of memory when allocating %u bytes") at failures.c:201 #14533 0x080b1652 in mem_block_alloc (min_size=0) at data-stack.c:192 #14534 0x080b1811 in t_malloc_real (size=16, permanent=true) at data-stack.c:244 #14535 0x080b1890 in t_malloc0 (size=16) at data-stack.c:279 #14536 0x080b8715 in pool_datastack_create () at mempool-datastack.c:51 #14537 0x080bda2b in t_str_new (initial_size=512) at str.c:17 #14538 0x080b21f3 in internal_handler (log_type=70 'F', ...

It seems like once we fall into i_internal_fatal_handler(), dovecot should really try hard to avoid further dynamic memory allocation, as heap corruption seems to make that a bit of a disaster. As for the crash in mbox_list_next, we see that one too with some frequency. A final problem, and this one affects me personally, is that we see some errors like this: dovecot: Jul 09 11:52:10 Error: IMAP(dp): FETCH for mailbox mail/tmp-inbox UID 92086 got too little data: 6054 vs 6057 dovecot: Jul 09 11:52:10 Info: IMAP(dp): Disconnected: Disconnected This is frustrating because I wind up with "poisonous" messages in my inbox which cause dovecot to disconnect me when I try to read them. Across all of our users, we see this happen about 1000 times per month. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Deliver mail as 'read'?
by Peter Collinson 21 Jul '08

21 Jul '08

I'd like to be able to deliver certain mail as 'read' from procmail. My procmail rules call deliver with -m to directly to inject filtered mail to maildir based directories. I like to keep copies of mail I've sent by cc'ing it to myself and using procmail to filter and store copies in the appropriate directory. I cannot seem to find a way of delivering cc'd mail from me to me as 'read'. I'm running dovecot-1.0.7-2.el5 on a CentOS 5 distribution. Any hints on how I may achieve this are welcomed. Happy to upgrade if needs be. Thanks. _____________________________________________ Peter Collinson

[Dovecot] The case of the disappearing INBOX's - upgrade to 1.1.1 from 1.0.7 and based on Email client type
by Jack Stewart 21 Jul '08

21 Jul '08

Hi, I apologize if this has already been answered. I looked for an identical message but had no luck. I'm also not convinced this is a bug or if it is a bug that I want it fixed. The problem gives me a great reason to change our configuration to something more modern. Here is the situation. Our 1.0.7 configuration has the following, and only, namespace definition. namespace private { separator = . prefix = Mail. inbox = yes } This configuration was implemented years ago in order to simplify the upgrade from mail spool to IMAP for people who use mutt and pine. The interesting part is that after upgrading to 1.1.1, the INBOX would disappear from Thunderbird after clicking on a different folder. Now mutt worked just fine, which was even worse. Changing the configuration so that the INBOX appeared on Thunderbird caused the INBOX to disappear (or be unreachable) on mutt. After trying multiple configurations with every permutation, and making several wall dents with my forehead, I finally found this configuration. namespace private { separator = . prefix = INBOX. inbox = yes hidden = no list = yes } namespace private { separator = . prefix = Mail. hidden = yes list = no } For the most part, this works just fine. INBOX appears for every client I've tested and the migration is largely transparent. The only time I found issues is when the Trash, Sent, etc. folders were manually specified in a GUI client such as Thunderbird. Still the real question remains. Is this supposed to happen? If so, what are some of the reasons? Naturally my management would prefer that the original configuration works the same so that things are transparent. Personally, the second configuration feels better to me especially on a going forward basis. Thanks in advance for any answers or hints. ---Jack -- Jack Stewart jstewart(a)caltech.edu http://www.imss.caltech.edu

Re: [Dovecot] litte problems upgrade from 1.0.x to 1.1.1

I can recreate it with dovecot 1.1.1 running on my machine. I create completly new mbox, write to it and when i view mbox in console i see just this mail. After deleting (pop3) this mail with our webmailer or OutLook Express etc. I see this internal message with current date. I do not belive in Clients that put internal mesages by pop3-protocol, but what should it be else? pop/imapserver is dovecot 1.1.1 And why this case just happens by updateing from 1.0.x to 1.1.1 and not during further updates from 1.0.x to 1.0.x+1 ? If you say this is not dovecot related i have to accept this but i am a little bit doubtful... Unfortunately i have now a more annoying error in imap processing. Sometimes it happens that dovecot seems to be out of sync.

[Dovecot] recursive acl problem
by Robert Schetterer 21 Jul '08

21 Jul '08

Hi, i ve got a problem with recursive acl, using not a vfile global backend. ( no default acl) In my understanding every folder(directory) needs a seperate dovecot-acl files with permissions. This works fine, but my tests showed using a shared namespace like i.e. namespace shared { separator = / prefix = "users/%d/" location = dbox:/usr/local/virtual/%d/ inbox = no list = yes subscriptions = yes hidden = no } and have dovecot-acl in usr/local/virtual/%d/ with authenticated l which means lookup, leads that all folders and subfolders of /usr/local/virtual/%d/%u/ are imap browseable, which means its recursive somekind. ( people will not like seeing folder names of their mailboxes until they dont gave permissions explicit to others) In my meaning this shouldnt be so only names of ( names of directories) at /usr/local/virtual/%d/%u/ should be shown , subfolders in them should only be imap browseable if there is another dovecot-acl in them which permits lookup i may fail here , anyone which has some enlightment for me outside? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Mails "invisible" (index corrupted?)
by Patrick Nagel 21 Jul '08

21 Jul '08

Hi, I got a complaint from a user today, that a few mails "disappeared" from her Inbox, both when accessing via IMAP with Thunderbird and in the IMAP Webmail client (RoundCube Webmail, caching deactivated). Searching (in Subject or From header) within the Inbox turned up the missing messages though. After checking all relevant client settings (filter rules etc.), restarting Thunderbird multiple times, etc., I tried deleting her dovecot.index.cache file, restarting Thunderbird again, but that didn't change anything. Only after deleting dovecot.index.*, everything went back to normal. I can't find anything useful in the log. Setup: x86, CentOS Linux, dovecot 1.1.1 (current stable binary from ATrpms), maildir storage, mail_debug is turned on Any hints on what could have caused this? Where to look? I backed up dovecot.index, dovecot.index.cache and dovecot.index.log before I deleted them, but they probably contain sensitive information, so I won't post them to the list. Thanks, Patrick. -- STAR Software (Shanghai) Co., Ltd. http://www.star-group.net/ Phone: +86 (21) 3462 7688 x 826 Fax: +86 (21) 3462 7779 PGP key: https://stshacom1.star-china.net/keys/patrick_nagel.asc Fingerprint: E09A D65E 855F B334 E5C3 5386 EF23 20FC E883 A005

[Dovecot] Multiple quota roots with quota-fs backend
by Ralf Becker 21 Jul '08

21 Jul '08

Today I've tried to configure multiple filesystem quotas, with some strange results. These are my two filesystems; both using quotas: * /dev/mail mounted to /var/spool/mail using AIX quotas for all users. Mailbox format is 'mbox' and they are named '/var/spool/mail/<logname>' * filer0:/vol/home mounted to /home/f0 via nfs using netapp quotas for all users. Mailboxes are all 'mbox' and located in '~<logname>/Mail' I've configured _two_ quota roots as described here: http://wiki.dovecot.org/Quota/FS?highlight=(two%20filesystems) plugin { quota = fs:Home:mount=/home/f0 quota2 = fs:Spool:mount=/var/spool/mail } This works like a charm, but when testing the configuration, the result was just surprising: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. You see, that _always_ both quota roots are reported, whether the references mailbox is actually placed on this filesystem or not. However reading RFC2087 confirms me in the idea, that just the _related_ quota roots should be listed: -------------------------------8<----------------------------------------- 4.3. GETQUOTAROOT Command Arguments: mailbox name Data: untagged responses: QUOTAROOT, QUOTA Result: OK - getquota completed NO - getquota error: no such mailbox, permission denied BAD - command unknown or arguments invalid The GETQUOTAROOT command takes the name of a mailbox and returns the list of quota roots for the mailbox in an untagged QUOTAROOT response. For each listed quota root, it also returns the quota root's resource usage and limits in an untagged QUOTA response. Example: C: A003 GETQUOTAROOT INBOX S: * QUOTAROOT INBOX "" S: * QUOTA "" (STORAGE 10 512) S: A003 OK Getquota completed ------------------------------->8----------------------------------------- So in my opinion correctly reported quota roots should look like this: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Spool" * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" * QUOTA "Home" (STORAGE 310360 1048576) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. Now I known what I want... but how to get it :-) While I see no way to use namespaces and/or quota rules to configure this behavior, patching quota.c, quota-fs.c and quota-private.h seems to be an option. A downside of this is, that I've to extend the quota plugin interface (quota_backend_vfuncs) defined in quota-private.h by adding an new callback function. Since all other quota backends don't have this new function, they have to initialize it with NULL. So there are side effects to other quota backends. This is the reason why I want to discuss the above described problem (and solution) before posting my patch :-) Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] v1.1.1: Some files not created with dovecot-shared permissions
by Eduardo M KALINOWSKI 21 Jul '08

21 Jul '08

Hi, I use dovecot-shared to add read permissions to the group in my mail server, which uses virtual users. This is only to ease backups. However, a few files are not created with the permissions in dovecot-shared. I've seen this happen to 'subscriptions', 'maildirfolder' (when dovecot-shared exists; the change to correctly create maildirfolder in this case is very recent), and possibly 'maildirsize' (I'm not sure about this one, it might be exim that is creating it with wrong permissions.) This has been tested in recent snapshot package, from the Debian repository listed at http://wiki.dovecot.org/PrebuiltBinaries. Here's dovecot -n for reference: # 1.1.1: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: username_format=%n /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir
