[Dovecot] making IMAP quicker on LAN
by Andrew Von Cid 24 Jul '08

24 Jul '08

Hi all, I keep on hitting this problem when migrating new clients from POP or local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is hosted properly in a data center. People usually complain that it's slower and although they're getting a kick ass mail setup it doesn't look good from their point of view. I'm wondering if there is anything I could do to speed it up on their LAN's. What I mean is probably a caching IMAP proxy or some sort of replication to a local Dovecot server. Is this something Dovecot can do? I'd be really grateful for any opinions on how to tackle this problem. Many thanks, Andrew.

[Dovecot] how to store flags \Seen into read-only mailbox?
by seriv＠parkheights.dyndns.org 24 Jul '08

24 Jul '08

Hi, I'm trying to use dovecot for storing mailing lists and read-only access for users. The OS is Solaris, authentication for all readers of these lists are from Ldap through PAM, and one local user "listuser" will receive all mail and store them into it's folders (Maildirs). These maildirs are readable (read-only) for all others and they are shared by setting --- mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index --- Mail became readable because in each mail folder to be shared there is dovecot-shared with mode 064, and all users included into his group. But this is the problem: how to have flag \Seen stored in read-only mailbox? As recorded by rawlog, it is ignored now: --- bash-3.00# cat 20080724-103219-10616.in 3 namespace 4 lsub "" "*" 5 list "" "INBOX" 6 list "" "Trash" 7 create "Trash" 8 select "OmniTI.FreeLotto.Ops" 9 UID fetch 1:* (FLAGS) 10 uid store 1:3 +Flags (\Seen) 11 IDLE DONE 12 close 13 logout bash-3.00# cat 20080724-103219-10616.out * OK [RAWLOG TIMESTAMP] 2008-07-24 10:32:19 * NAMESPACE (("" "."))

Hmm. I don't necessarily see that as a desirable feature because in the case that something is actually wrong with the spam tagging you want to notice it isn't working right. If you really need that, just don't set an error when it happens and do nothing, allowing the move. johannes

Binc was set up like this : depot = "IMAPdir", /* Use Maildir++ style type = "Maildir", /* only Maildir path = "Maildir", /* default path */ auto create inbox = "yes", /* create INBOX in auto subscribe mailboxes = "INBOX", /* list mailboxes umask = "077" /* use this umask I have dovecot set up thusly : mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir namespace private { separator = / prefix = INBOX/ inbox = yes hidden = yes } The problem is, I'm not seeing any folders..

[Dovecot] v1.1.2 release candidate
by Timo Sirainen 24 Jul '08

24 Jul '08

I've finally read and answered most of the mails on this list. If you haven't received an answer to your question, resend it. There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems. There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two. So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz Largest changes since v1.1.1 are: + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed

[Dovecot] Problems with deliver and account resolving
by Andreas Podgurski 24 Jul '08

24 Jul '08

Hi! I'm currently setting up my first mailsystem based on dovecot. For a far way, working with dovecot was very convenient, but after I had to integrate deliver, it became massivly painful. My components are postfix as MTA, postgresql as user database and dovecot as IMAP server. When translating the mail adresse into the account name, something goes terribly wrong (Mail adresses modified to protect against spam, think about them in correct format): dovecot: Jul 22 01:48:13 Info: auth(default-listen): master in: USER 1 Andreas.Podgurski_at_MediaGUILD.de service=deliver dovecot: Jul 22 01:48:13 Info: auth(default-listen): prefetch(Andreas.Podgurski_at_MediaGUILD.de): passdb didn't return userdb entries, trying the next userdb dovecot: Jul 22 01:48:13 Info: auth(default-listen): sql(Andreas.Podgurski_at_MediaGUILD.de): SELECT 1011 AS uid,1011 AS gid,'/var/www/jade/mail/' || admin.username AS home,admin.username AS user FROM admin,email WHERE lower(email.local_address) = lower('Andreas.Podgurski') AND email.receiver = admin.id; dovecot: Jul 22 01:48:13 Info: auth(default-listen): auth(Andreas.Podgurski_at_MediaGUILD.de): username changed Andreas.Podgurski_at_MediaGUILD.de -> SunAdmin dovecot: Jul 22 01:48:13 Info: auth(default-listen): master out: USER 1 SunAdmin uid=1011 gid=1011 home=/var/www/jade/mail/SunAdmin deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Error: mkdir(/var/www/jade/mail/Andreas.Podgurski_at_MediaGUILD.de/cur) failed: Permission denied deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Info: msgid=<20080721234813.302260(a)gmx.net>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2008-07-22 01:48:13] As you can see, the account SunAdmin has an email adresse andreas.podgurski_at_mediaguild.de assigned. The database seems to reveil the username correctly, but after that, deliver continues to use the original mail adresse, not the account name returned by the auth master. Any idea, where my solution went the wrong way? The uid/gid belong to vmail:vmail, which is used for the auth-master, as well as for running deliver and to dispatch the postfix messages. Btw., I ask myself, how dovecot can assume to use prefetch in this case, as prefetch bases upon the password query, which has to fail in this case, as there is no password. Shouldn't it not even try to use the prefetch values there...? Thanks in advance, Andreas Podgurski -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

[Dovecot] cosmetic: "userdb" checkpassword
by Heiko Schlichting 24 Jul '08

24 Jul '08

Hi, $ dovecot --build-options Build options: ioloop=epoll notify=inotify Mail storages: maildir SQL drivers: Passdb: checkpassword Userdb: checkpassword prefetch Isn't "checkpassword" misplaced in the userdb list? For me it seems that USERDB_CHECKPASSWORD is only used in configure and for printing the build-options. Additionally checkpassword protocol does not makes any sense for a userdb. It could be used only for passdb plus prefetching userdb. Therefore I suggest to remove USERDB_CHECKPASSWORD to make this more obvious althought this is only cosmetic.

[Dovecot] Problem authenticating iPod Touch

[Dovecot] \HasNoChildren versus \Noinferiors in ACL plugin and no CREATE permission
by Heiko Schlichting 23 Jul '08

23 Jul '08

Hi, using ACL plugin with dovecot 1.1.1 I expected that a Maildir was listed as * LIST (\NoInferiors) "/" "Foldername" if "create" (k) permission is not set in ACLs and there doesn't exists any subfolders. But to my surprise, dovecot gives the following output: * LIST (\HasNoChildren) "/" "Foldername" Therefore the client (here: SquirrelMail) does not know about the inability to create subfolders and offers "Foldername" in the selection for the parent folder. If there are exists already subfolders of "Foldername", dovecot has to use \HasChildren and not \NoInferiors. But in other cases \NoInferiors should be the correct answer and not \HasNoChildren. Or am I totally wrong?

[Dovecot] Mailbox_module_context question
by Daniel Brosseau 23 Jul '08

23 Jul '08

Hi, I am new to the dovecot source and would like to know why the mailbox_module_context has a pointer to the mail_storage_module_register and not to a mailbox_module_register. From what I have understood, if a context is first added to the mailbox.module_contexts array using the mail_storage_module_register and then a context is added to the mail_storage.module_contexts and then a third context is again added to the mailbox.module_contexts the mail_storage_module_register.id will be 3 and the second element in the mailbox.module_context will be unused and the first and third elements of the mail_storage.module_contexts are unused. There might be something I am not understanding here so please forgive me if my question has an obvious answer. Daniel

[Dovecot] 1.1.1-1 gotcha with Fedora Rawhide package
by Kenneth Porter 23 Jul '08

23 Jul '08

I just installed the Rawhide package on my CentOS 5 system. The one item that bit me is that the config file defaults to using interface "[::]" so it only listens on IPv6. (This is from a patch in the package that changes the upstream default of "*", so it only affects those using the Fedora package.) For those wanting to track the issue, here's the Bugzilla: <https://bugzilla.redhat.com/show_bug.cgi?id=453054> I rebuilt the package from the source RPM, to make sure it was "tuned" to the C5 distro. I got the source RPM here, from the Portland State mirror: <http://mirrors.cat.pdx.edu/fedora/linux/development/source/SRPMS/dovecot-1.…> Here's a full list of Rawhide mirrors: <http://mirrors.fedoraproject.org/publiclist/Fedora/development/> If you'd like to see all Red Hat bugs associated with dovecot, here's a suitable query: <https://bugzilla.redhat.com/buglist.cgi?component=dovecot>

[Dovecot] Namespaces

Hi all, I'm working to convert from a bincIMAP setup to a Dovecot setup. I've tried messing around with namespaces to make the conversion transparent, but I'm getting nowhere. Are namespaces necessary? Or can I proceed by recursively renaming the folders on the server? A transparent solution would be wonderful, but I can't get it to work for me.. Any help would be appreciated. Thanks! -- Jason 'XenoPhage' Frisvold XenoPhage0(a)gmail.com http://blog.godshell.com

[Dovecot] Sieve plugin should recompile when symbolic link changes [patch]
by Frank Behrens 22 Jul '08

22 Jul '08

The sieve plugin compares the modification dates of sieve source and compiled script and compiles the script only if necessary. When the managesieve extension is used, it creates a symbolic link for the script. In order to switch between scripts managesieve changes the link only. Therefore the sieve plugin should include the modification date of an symlink in its decision about compilation. The attached patch adds this functionality.

[Dovecot] ACL in sub-folders (take two)
by Imobach González Sosa 22 Jul '08

22 Jul '08

Hi all, I've read this not on the v1.1.2 release candidate announce: > If you haven't received an answer to your question, resend it. So, I've sent this message some days ago and I've got no answer (that's fine, no problem). So, I'm posting my question again: I've set up some shared folders and I'm controlling the access to them with the ACL plugin. As far as I know, ACL rules are not applied to sub-folders, right? So, when a user adds a new sub-folder, I need to add a dovecot-acl file granting read permissions to others users, right? Does exists any way to implement it using some dovecot feature? Or must I find my way? Just to be sure :) Thank you in advance. -- Imobach González Sosa Banot.net http://www.banot.net/

[Dovecot] Dovecot LDA with Postfix - question?
by kbajwa 22 Jul '08

22 Jul '08

Hello: CentOS 5.2 Postfix 2.3.3 (part of CentOS install) Dovecot 1.0.7 (part of CentOS install) Dovecot 1.1.1 (Updated from www.atrpms.net) Postfix & Dovecot are working fine. While reading "Dovecot LDA with Postfix" document at http://wiki.dovecot.org/LDA/Postfix , I read the following statement: --------------------- Dovecot LDA with Postfix System users If you wish you use deliver for all system users on a single domain mail host you can do it by editing mailbox_command parameter in /etc/postfix/main.cf (postconf(5)): mailbox_command = /usr/local/libexec/dovecot/deliver # or mailbox_command = /usr/libexec/dovecot/deliver # or mailbox_command = /usr/lib/dovecot/deliver # or wherever it was installed in your system. Then run postfix reload and that is it. --------------------- Here is the problem; I do not find location of ".../dovecot/deliver" anywhere on the system! 1. Did I do any mistake during the Postfix and/or Dovecot install/configuration? 2. Next, I plan to install "Dovecot-Sieve". Do I need the "mailbox_command" for "Dovecot-Sieve" to work? Kirti

[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', ... At the top of the stack, I see this-- unfortunately I can't use gdb to view it-- it core dumps after about 50,000 frames.

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
