[Dovecot] Support of M-IMAP?
by Peter Hessler 16 Feb '06

16 Feb '06

I was looking at some new mobile phones, and apparently there is a form of IMAP that is optimized for mobiles called M-IMAP. Its not a rush (since I'm not even sure the phones will be out before Q2), but it'd be a cool thing to have. The spec is in the following PDF. http://www.3gpp2.org/Public_html/specs/X.S0016-311_v1.0_022404.pdf -- Klein bottle for sale ... inquire within.

[Dovecot] maildir and stat
by David Spidley 16 Feb '06

16 Feb '06

Hi. I plan to use dovecot on nfs with maildir. Does dovecot need to stat each file in a maildir, or does it just read a list of files in the directory? i.e. does it do the equivalent of an ls -f, or an ls -l? HYCH

[Dovecot] ugly hack to make maildir quotas work
by Joshua Goodall 16 Feb '06

16 Feb '06

Timo encouraged me to forward this to the list. Basically it pokes the right value into the right place to make quota deltas work properly when saving mail to Maildirs. It's a nasty hack workaround, so don't rely on it without understanding that it should be superseded in future. Without this, saving to a maildir doesn't increment quota. --- src/lib-storage/index/maildir/maildir-save.c 14 Jan 2006 18:47:50 -0000 1.64 +++ src/lib-storage/index/maildir/maildir-save.c 16 Feb 2006 04:32:49 -0000 @@ -9,6 +9,7 @@ #include "str.h" #include "maildir-storage.h" #include "maildir-uidlist.h" +#include "index-mail.h" #include <stdio.h> #include <stdlib.h> @@ -233,6 +234,7 @@ struct utimbuf buf; const char *path; int output_errno; + struct stat st; if (ctx->failed && ctx->fd == -1) { /* tmp file creation failed */ @@ -264,6 +266,9 @@ "fsync(%s) failed: %m", path); ctx->failed = TRUE; } + if (fstat(ctx->fd, &st) < 0) { + ctx->failed = TRUE; + } if (close(ctx->fd) < 0) { mail_storage_set_critical(STORAGE(ctx->mbox->storage), "close(%s) failed: %m", path); @@ -297,6 +302,8 @@ if (mail_set_seq(dest_mail, ctx->seq) < 0) return -1; + + ((struct index_mail *)dest_mail)->data.physical_size = st.st_size; } t_pop(); /k -- Josh "Koshua" Goodall "as modern as tomorrow afternoon" joshua(a)roughtrade.net - FW109

[Dovecot] Question regarding 'dovecot-auth'
by Paul E Virgo 16 Feb '06

16 Feb '06

Hello Timo, I am compiling dovecot-1.0.beta3, and I get the following message when the dovecot-auth module is being compiled: Undefined symbol sql_drivers_register_all first referenced in main.o Now I had run 'configure' with the '--without-sql-drivers' since I neither have MySQL or PostgresSQL installed on my server. Does this mean I DO have to get either package, install, and run it '--with-sql-drivers'? Or is it that the '--without...' feature doesn't work as intended? Am I making ANY sense? Thanks.

[Dovecot] NFS Stale File Handles on Indexes
by Tony Kay 15 Feb '06

15 Feb '06

The configuration files has settings that seem to address the issues of using indexes on NFS (i.e. locking and mmap fixes), but we are using Dovecot on NFS, and when the load gets high we start to see a lot of NFS stale file handle errors, particularly with MS clients like Outlook. I see the discussion about these errors from last year. Any updates on the state of the code? Should we be using in-memory or local indexes instead for now? - Dovecot 1.0b3 - four physical IMAP servers - mbox format accounts on NFS netapps - currently allowing NFS indexes w/mmap disabled, and using dotlocks -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Perfection uncanned Like a beautiful redhead Fresh from her trailer from Spam-Ku : Tranquil Reflections on Luncheon Loaf by John Cho

[Dovecot] imap_capability setting
by Bill Boebel 15 Feb '06

15 Feb '06

In src/master/master-settings.c, there is a config variable "imap_capability" that is read in from the conf file... but in the rest of the code it looks like that variable is never used. I assume this is there for future use, but just wanted to confirm that the code not using it was intentional. Since we are using Dovecot as an IMAP proxy for a Courier backend (for now), we need to advertise a different capability string than the Dovecot default. I have changed the hardcoded value in the ./configure script (@ 31015) for now. Bill

[Dovecot] Dovecot RFC non-compliance: Mailbox names
by Tony Kay 15 Feb '06

15 Feb '06

Hi, I think I already know the answer to this and I agree with it, but I have a question about "invalid" mailbox naming decisions in dovecot. Technically, RFC3501 (Section 5.1, pg. 18, client consideration 3) says that * and % are legal in mailbox names, though it implicitly discourages their use. We just migrated to dovecot, and unfortunately have a few users who used * in their mailbox naming (which worked on our old IMAP server). I looked in the mailing list and source comments, but I could not find any discussion. Was there any discussion about the imap/commands-util.c:48? 46: /* make sure it even looks valid */ 47: sep = mail_storage_get_hierarchy_sep(storage); 48: if (*mailbox == '\0' || strspn(mailbox, "\r\n*%?") != 0) { 49: client_send_tagline(cmd, "NO Invalid mailbox name."); which is technically not RFC-compliant? I have a feeling it fixes much more important things than it breaks (i.e. LIST/LSUB), but then again we never had complaints from people using those characters in names until they stopped being supported. -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Sanity is a cozy lie.

[Dovecot] dovecot-LDA and fromwho-argument
by Björn Ketelaars 15 Feb '06

15 Feb '06

Hello, Im using dspam 3.6.3 in combination with Dovecot, procmail and Sendmail. Everything works fine but I want to replace procmail by dovecot-LDA. A few changes to dspam.conf results in a takeover by dovecot-LDA. Unfortunately this is where it goes awry; besides the d argument (user), dspam also supplies the f argument (fromwhom). The use of the f argument results in an error because dovecot-LDA does not know what to do with it. Is there an option to ignore the passing of 'fromwhom' from dspam? -- In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule.

[Dovecot] Message index corruption when using Thunderbird and Dovecot
by Reuben Pearse 14 Feb '06

14 Feb '06

Hi all, I have recently upgraded from UW-IMAP to Dovecot 1.0.beta3 on Redhat9. I migrated my mailbox to from Mbox to Maildir using the mb2md perl script, and created a procmail recipe file to get email arriving in the Maildir directories. However, when accessing my mailbox from Thunderbird (version 1.5), it occasionally mixes up the email header with the email content. I also occasionally get errors like this when clicking on old messages (ones that got converted as part of the mb2md script). The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' in '<16384.-15744>' However, if I click on the email item again, Thunderbird is then able to retrieve the message correctly. Can anyone provide some help with these problem.

[Dovecot] Re: Mail.app help
by Roger Weeks 14 Feb '06

14 Feb '06

I'm wondering if this is a version issue with Mail.app? Are you on OS X 10.3 or 10.4? The reason I ask is that we also migrated from Courier IMAP to Dovecot 1.0alpha5 and then beta3, and we did not have this problem with Mail.app that either of you are describing. I did have to remove the "INBOX." prefix from my Mail.app configurations. I also renamed all of the existing folders in my Maildir from INBOX.foldername to .foldername, because after removing the "INBOX." prefix Mail.app could not see them. Before I renamed all of the existing folders and changed the prefix in Mail.app, I had also tried setting up alternate namespaces as described in the wiki documentation for converting from Courier, but that did not seem to work. Mail.app and Thunderbird clients could not see their IMAP folders with the courier-style namespace configuration. -- Roger J.

[Dovecot] Dovecot-1.0.beta1: New mail sometimes fails to appear
by Tom Alsberg 14 Feb '06

14 Feb '06

Hi there... Having updated to 1.0.beta1, I for a while thought a bad bug with IDLE handling that caused new mail in INBOX not to appear when using Mozilla Thunderbird has been solved. Although I can not reproduce one kind of problem anymore, after a short while it again appears that one does not always see one's new mail with Thunderbird. I can not consistently reproduce the bug, but from some network captures it indeed appears that sometimes Thunderbird has (in one of its connections to the server) INBOX SELECTed and IDLE on it, new mail arrives, but 10 minutes afterwards it was still not sent an EXISTS message. Initially the symptoms appeared to suggest that something really bad happened to the index files, but I tried INDEX=MEMORY and that did not help much. Thunderbird using multiple connections to the server does of course only make debugging more difficult. But it appears that without multiple connections, one has to constantly cycle around SELECTing to get notified on more than one mailbox, so that may justified. I am a bit lost on this now, and would appreciate some ideas. Although there were several related bugs I noticed in Thunderbird 1.0, it appears that they are gone in 1.5, and yet now it really seems Dovecot is doing something wrong here. Attached is the configuration file I use for the testing installation of Dovecot 1.0.beta1 (somebody tell me if you see something wrong there). The mailbox arrangement is as follows, right now (until we have a better way): * INBOX in /var/mail/%u * most mailboxes in ~/imap.maildir/... as maildirs. * mboxes in ~/imap.mbox/... accessible as #imap.mbox/... * the mbox:~/mail/ is for when namespaces are not used - now there are so it should not be relevant Except for myself, and one test account I have, I have two guinea-pigs using it (who are well aware that it is still under development and that it will break once in a while) and reporting problems to me. Vaguely (since I can't figure the exact reasons), the symptom can be described as follows: When using Mozilla Thunderbird to access mail, new mail arrives to INBOX (mbox:/var/mail/%u), but is sometimes not seen for a long while after it arrives. Sometimes the first (or first few) message arriving appears, but then no new messages appear, and sometimes everything works right and immediately new mail is seen. However whenever (according to Thunderbird) something changes in the mailbox, the mailbox is seen up-to-date as it really was at that time.

[Dovecot] Mail.app help
by Mike Garfias 14 Feb '06

14 Feb '06

I'm having a problem with Mail.app and imap folders. I've got a new install of dovecot 1.0beta2, and am only experiencing this problem with Mail. Mutt works as expected, as well as thunderbird. When I create a folder using Mail.app, it is written to ~/Maildir/.INBOX.newfolder, which would be fine, if I wasn't telling everything that I wanted no prefixes. If I move that folder to ~/Maildir/.newfolder, Mail.app can no longer see it, but mutt and thunderbird can. Thunderbird _CAN_ see the folders created as .INBOX.Folder, and even shows it as a subfolder of my inbox, but Mutt completely refuses to see it. Any ideas what I'm doing wrong here?

[Dovecot] nologin

I need to be able to setup a nologin system for users on my mail server on a per user basis. We are going to do some maintenance on each user (individually) and would like it if they could not login to dovecot while we do this. I was curious if dovecot implemented anything like this. We are currently using standard pam authentication (nothing db related) and I was hoping to be able to touch a "nologin" file on a per user basis in their home directory. I think I could do this with some pam magic, but was curious if dovecot had something in it that would allow for this. Note: I understand I will have to forcibly kill active connections. --Robert

[Dovecot] Problems with POP3 UIDL when migrating from MBOX to Maildir
by Jonas Olsson 14 Feb '06

14 Feb '06

Hello, I am in the process of migrating a hosting setup from UW-IMAP to Dovecot. The protocols available to mail clients are IMAP and POP3 both before and after migration. I also wanted to change the mail storage format from MBOX to Maildir. However, at this point I hit a major snag with Dovecot and POP3 UIDL (unique identification listing for POP3 mailboxes). Several of the customers connecting to the mailserver in question are using POP3 clients and leave their e-mails on the server. To avoid downloading all messages every time the clients connect they use the UIDL command in the POP3 specification to determine if any new messages have arrived since last time they checked. In order for this to work the unique identifier of each message must be static and can never change. If the identifiers change, every client will download all messages again, mixing old messages with new, in the belief that all messages are new since their identifiers changed.

[Dovecot] IMAP timeout
by Eugeny N Dzhurinsky 14 Feb '06

14 Feb '06

Hi there! Is it possible to set timeout for IMAP connection somehow? The problem is when I'm using mutt to access IMAP mailbox, everything works fine, but after some idle time mutt tells mailbox is closed and next connection crashes it. With courier mutt works just fine, so I think may be dovecot have some timeout which need to be adjusted? I checked manuals and configuration, but no luck... In both cases (dovecot/courier) I'm using IMAP over SSL -- Eugene N Dzhurinsky

[Dovecot] locking problems with RHEL 3 and dovecot
by Dan Bongert 13 Feb '06

13 Feb '06

I just migrated from a FreeBSD/Sendmail/UW-IMAP setup to RHEL 3/Postfix/Dovecot (1.0a5 currently). Both systems used Procmail as the final delivery agent (into inboxes or . Since the changeover, things have *mostly* been going ok, but I've been having some problems that I think are locking-related. I'm getting reports from users about IMAP hangs (mostly from Thunderbird). Sometimes I see this in the Dovecot logs: ovecot: Feb 06 11:30:45 Error: imap(dbongert): fcntl() failed with mbox file /home/d/dbongert/mail/worklists/tech-partners: Resource temporarily unavailable Now, I have read that one should have everything that touches a mailbox use the same sort of locking, but that's the thing--these mailboxes are only accessed via dovecot. I'm sure a few users use procmail to filter their mail, but they're in the strict minority here. As as experiment, I changed these lines to flock rather than fcntl: mbox_read_locks = flock mbox_write_locks = dotlock flock But all that seems to have done is removed the fcntl errors from the log file. These errors seem to be Thunderbird only (1.07-1.5, Linux and Windows clients), but I'm not sure what that means. I've enabled the only thunderbird-specific IMAP workaround I know of: tb-extra-mailbox-sep, but I doubt that has anything to do with this problem. -- Dan Bongert dbongert(a)ssc.wisc.edu SSCC Unix System Administrator

[Dovecot] Maximum Folder Size/Number of Messages
by Ropetin 13 Feb '06

13 Feb '06

I hope I'm asking this question in the right place, I don't want to offend. I've recently put together a proof of concept Dovecot IMAP server, and I'm very happy with its performance up to this point. I'm looking into using it to replace our existing POP3 server, allowing users to store email on the server rather than on their local machine, hopefully avoiding loss of data. The big question I have is, is there a realistic maximum realistic folder size, either in reference to number of messages or total file size with Dovecot? I'm using Maildir and running it on Debian Linux x86. Right now the filesystem is Ext3, although once the system goes live I'd be looking at something a little more fault tolerant and able to handle the large amount of data. Any recommendations you may have on Filesystem choice are appreciated too! Thanks, Ropetin.

[Dovecot] LDAP mailLocation weirdness
by Udo Rader 12 Feb '06

12 Feb '06

Hi, I've reported this some month ago before (without response), but still I have no clue what is going wrong. Our installation is LDAP based (for virtual hosting) and up to I think alpha2 or 3 everything was working as expected. The trouble I have is that dovecot does not correctly use the information it gets about mailLocation. This is what is stored in the MailMessageStore attribute for a user "f.someone": mbox:/virtual/oeush.at/var/mail/f.someone:INBOX=/virtual/oeush.at/var/mail/f.someone now despite of this setting, this user is unable to fetch any mail, because dovecot partially ignores this setting: ---------CUT--------- dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): Effective uid=200, gid=4000 dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/var/mail/f.someone.oeush.at dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): mbox: root=/virtual/oeush.at/home/f.someone/mail, index=/virtual/oeush.at/home/f.someone/mail, inbox=/var/mail/f.someone.oeush.at ---------CUT--------- As you can see, dovecot uses /virtual/oeush.at/... both for data and index but not for inbox, where it uses /var/mail/... My LDAP configuration for the mailLocation settings looks like this: ---------CUT--------- # User attributes in order: # Virtual user name (user@domain) # Home directory # MAIL environment # System user name (for getting user's groups from /etc/group) # - For virtual users you don't want to use this, so this defaults to none. # System UID # System GID user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber ---------CUT--------- So where am I wrong?

[Dovecot] Simulating UW Snarf...
by Todd Piket 10 Feb '06

10 Feb '06

I already wrote to Timo, but I thought some others on this list may have had a similar situation. So here goes: The scenario at Michigan Technological University stems from long standing traditions and policies that probably won't change. That said, two of the policies are 1.)we don't bounce mail and 2.)we guarantee delivery when we accept a piece of mail. The UW IMAP "snarf" capability was nice because it allowed us to introduce file system, per user quotas w/o worrying about the "INBOX" in an over quota situation. This is because the user could still read mail. The delivered mail would get "snarfed" from /var/mail/user when the user went back under quota. In our test cases with switching to Maildir with Dovecot, we deliver directly to the user's INBOX instead of /var/mail/user so what do we do when the user is over quota because we can't bounce the mail? After many lengthy discussions our thought was this. Could we symbolically link the user's "Maildir/new" to a non-quota file system such that the move from "new" to "cur" would fail if the user is over quota? What will Dovecot do in that failure situation? Do you have other suggestions? I would be more than willing to develop a patch that makes this an option in the config file. Probably similar to allowing the indexes and control files be on a non-quota file system. Again, it would only allow "Maildir/new" to be on a separate file system, not the whole "INBOX". I hope this conveys the idea well enough. Any thoughts or ideas the list provides would be greatly appreciated. -- Regards, ------------------------------------------------------------ | Todd Piket | Email: todd(a)mtu.edu | | Programmer/Analyst | Phone: (906) 487-1720 | | Distributed Computing Services | | | Michigan Technological University | | ------------------------------------------------------------

[Dovecot] In-memory Index file bug

Hi, I am getting intermittent error messages in the log when my mail client tries to create/open a folder named ".imhoprefs". Some accounts seem to able to do it, but I have at least one that gives the log error: Feb 7 09:29:54 acad-cl1 dovecot: imap(tkay): close() failed with index file (in-memory index): Bad file descriptor I traced through the code, and it seems to be coming from mail_index_close() (line 1527 of mail-index.c), which seems to be attempting to close a file descriptor for an index. The funny thing is that since I am using in-memory indexes, I believe that there shouldn't be any file descriptor to close, which would explain why the close is failing... Environment information: - Dovecot 1.0b2 - mbox - Environment setting: default_mail_env = mbox:%h:INBOX=%h/.mail:INDEX=MEMORY - Attempting to create/use a folder called mail/.imhoprefs At first, I though the folder itself might be corrupted, so I removed it.

[Dovecot] Maildir, imap and newness of messages
by Anand Buddhdev 10 Feb '06

10 Feb '06

I'm using the standard Dovecot 0.99.14 on Fedora Core 4, with a Maildir++ mailbox. I've noticed what I think is an oddity in the way dovecot handles messages: According to the Maildir specification, a message in Maildir/new is a truly new message, which has not yet been touched by any reader. From an IMAP viewpoint, such a message should have the flag RECENT. However, if a message exists in Maildir/cur, then it means that the message is no longer new (because some other reader has opened the Maildir, and moved the message from new to cur). From an IMAP viewpoint, such a message should NOT have the RECENT flag. However, dovecot seems to get this wrong. For example, if I have a message in Maildir/new, and I use mutt (a console-based maildir-aware mail client) to open the Maildir, then mutt moves the messages from Maildir/new to Maildir/cur (note here that I haven't actually read the message yet, just opened the Maildir with mutt). I expect that when I now open this Maildir with dovecot imap, and do a "select inbox", it should report "1 EXISTS" and "0 RECENT". However, dovecot reports this as "1 EXISTS" and "1 RECENT". In my opinion, this is a bug in Dovecot. Would any of the developers like to comment? Anand

[Dovecot] Dovecot stops logging of imap logins after logrotation
by Gerhard Hofmann 10 Feb '06

10 Feb '06

Hi list, on my Debian box there is a logrotation cron job that will gzip existing /var/log/mail.log file and create a new mail.log. It seems that after running logrotation dovecot stops logging successful POP or IMAP logins to /var/log/mail.log (nevertheless, it still works to login with POP or SMTP). This is bad because pop-before-smtp mechanisms also stop working. I have deactivated logrotation cron job and will monitor mail.log file. Maybe I should just run /etc/init.d/dovecot restart after logrotation script. What do you think? TIA Gerhard

[Dovecot] Programming Help
by Neal Katz 10 Feb '06

10 Feb '06

Hi, I was hoping you could provide me with some pointers on how to get started adding some features to dovecot. What I am trying to do is add an optional publish mechanism, that would publish a list of events as they occur, so that an external program could read these events and do "something". These events would be "Add", "Delete", "Move" - these would be posted every time a new message is added, deleted or moved. "CreateDir", "DeleteDir" would be published when a user creates a subf-folder or removes one. A simple example would be to configure the system to publish 'Add Message' events, and then an external program would read these, and send a notification event to web based users who are currently logged in. The publish feature would be controlled by the config file, and would be disabled by default The config setting would allow an administrator to specify what events to publish, the mechanism to use, and optional arguments for the mechanism For mechanisms I plan on developing a file based system, one file per event, written into a directory, the subscriber/reader would delete the file Other mechanisms could include TCP/IP based (connect to port XX, and send some data); or even connect to a commercial Message Queue product. Ex. Publish=ADD+DELETE+MOVE:file:/var/spool/imapevents Or Publish=ADD+DELETE+MOVE:tcpip:localhost:9999 It would help me a lot if you could just provide me with a few pointers as to the best place to add my features into the dovecot code, I took a quick look at the code and decided to contact you first before going ahead and putting things in the WRONG place. I did see the code for supporting inotify and similar mechanisms, but I don't see the big picture ? How does dovecot use inotify ?, what features are enabled that you don't get without inotify. If you have a code-roadmap, or architectural diagrams (or doodles) that would be helpful too. In terms of inotify, I don't think this will work for me, since I would like to have the user, Message-Id and Imap UIDL sent in the event message I hope this makes sense, if not just send me an email asking for clarification. All of the changes I make I will submit back to you, and hopefully they will be made part of the base product. Thanks, Neal Katz p.s. I chose Dovecot because I was very impressed with the ease of installation and migration (from courier), my early tests have shown it to be twice as fast when traverse all messages in a large mailbox ( 100K message ).

[Dovecot] Mixed IMAP/POP3 environment, a success
by Denis Sbragion 10 Feb '06

10 Feb '06

Hello everybody, I just want to inform the Dovecot developers and users that I completely migrated the first mailbox (my own one) from Eudora/UW to SquirrelMail/Dovecot. I'm using it since a couple of days and after a bit of tuning (mostly SquirrelMail related) it works like a charm. I even performed some heavy operations, like moving thousands of messages between different mailboxes or searching within a 1 Gb folder, and performances are indeed great. My sincere greatest compliments to the Dovecot developers and my biggest thanks to the people who helped me. No wonder that Fedora/RedHat has decided to adopt Dovecot as the default IMAP server for future releases. It looks like the perfect balance between security, performances, flexibility, standards conformance and ease of use.

[Dovecot] Dovecot 1.0b2 now in pkgsrc packaging system
by Todd Vierling 10 Feb '06

10 Feb '06

After months of testing in the "work in progress" pkgsrc-wip playground, dovecot-1.0b2 is now in the main pkgsrc mainline and will be tracked up through the 1.0 release and beyond. This means it's now much easier to get Dovecot 1.0 up and running on NetBSD and any other platform supported by pkgsrc (see www.pkgsrc.org) prior to this, 0.99.x was the newest available. Binary packages for NetBSD and some other systems should start appearing within a week or two of this message. As before, dovecot-nightly is still available in the pkgsrc-wip package tree, for those who like to live on the edge. -- -- Todd Vierling <tv(a)duh.org> <tv(a)pobox.com> <todd(a)vierling.name>

[Dovecot] Openwebmail with Dovecot
by ftnx＠ksbase.com 10 Feb '06

10 Feb '06

So far I've managed to get Dovecot to work fine for regular POP users and Squirrelmail. Even though it seems dead slow and obsolete, a few users would like to use Openwebmail. All users are virtual, and there are/will be no system accounts. Anyone have a working example for Dovecot/Openwebmail for virtual user setup?

[Dovecot] epoll error when running as proxy

I am running dovecot 1.0 beta3 as a front-end proxy, and getting the following error when using epoll. The error goes away if I switch to poll.

[Dovecot] trouble compiling today's CVS in Solaris 9
by Glenn Leavell 09 Feb '06

09 Feb '06

I've recently been able to compile the CVS code in Solaris 9, but I'm now getting a few errors. First, I receive this error during the autogen process: src/plugins/Makefile.am:5: required directory src/plugins/convert does not exist configure.in:1717: required file `src/plugins/convert/Makefile.in' not found I can workaround that by removing the reference to src/plugins/convert in configure.in. I then get this error: src/plugins/Makefile.am:5: required directory src/plugins/convert does not exist I can workaround that by removing the reference to the convert plugin from src/plugins/Makefile.am. After that, the autogen process completes and I get the previously discussed shell error when running make: if [ "" != "" ]; then \ for i in ; do \ echo "extern struct sql_db driver_${i}_db;" >>sql-drivers-register.c ; \ done \ fi /bin/bash: -c: line 1: syntax error near unexpected token `;' /bin/bash: -c: line 1: `if [ "" != "" ]; then for i in ; do echo "extern struct sql_db driver_${i}_db;" >>sql-drivers-register.c ; done fi' I can workaround that by simply running make from /bin/sh. I then get this error: Making all in auth make[3]: Entering directory `/home/glenn/dovecot/src/auth' /bin/bash ../../libtool --mode=link --tag=CC gcc -std=gnu99 -g -O2 -Wall ... <snip> userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o -L/usr/local/ssl/lib libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lcrypt -lpam -lldap -ldl -lsocket -lnsl -lrt -lsendfile Undefined first referenced symbol in file sql_drivers_register_all main.o ld: fatal: Symbol referencing errors.

[Dovecot] configuring lda
by Lenny 09 Feb '06

09 Feb '06

after coping lda stanza into the config file, I get "unknown protocol name" error. adding lda to the list of protocols doesn't seem to do the trick. lda was built during compile and the binary is present, piping into it manually spits error messages about missing config, so how do I go about the problem above ? It is my undertanding that using dovecot-lda would help maintain the indexes in proper state ( as opposed to using procmail and having to rebuild indexes from scratch upon delivery of large amounts of mail ) ? mucho gracias to you all. protocol lda { # If you wish to use plugins you need to specify plugin directory # For example quota enforcing is implemented by plugin #module_dir = /usr/local/lib/dovecot/lda # Address from LDA should send MDNs like out of quota postmaster_address = postmaster(a)your.dom # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = # UNIX socket path to master authentication server to find users. auth_socket_path = /var/run/dovecot-auth-master }

[Dovecot] Broken NSS Implementation
by Campbell McKilligan 08 Feb '06

08 Feb '06

We're getting this error when IMAP clients attempt to authenticate using their aliases rather than their actual username: Feb ... dovecot: auth(default): BROKEN NSS IMPLEMENTATION: getpwnam() lookup returned different user than was requested (campbellmckilligan != campbell.mckilligan). Feb ... dovecot: imap-login: Internal login failure: user=<campbell.mckilligan>, method=plain, rip=82.148.120.110, lip=172.20.2.2, TLS Feb ... dovecot: child 27345 (auth) returned error 89 For historic reasons, there is no consistency with which username in individuals mail client. NSS correctly returns the name that dovecot should use for the purposes of accessing mailboxes etc. Dovecot-0.99.14 worked fine in this regard - but since upgrading to 1.0beta3 we have this problem. It's running on a Fedora Core 4 server. It compiled fine with selinux enabled. Is there a switch to control the response to this NSS behaviour? Any help appreciated. Campbell

I don't think that UW-IMAP was expunging messages because I could open up the mbox with pine and see all of the messages flagged as "Deleted" but not yet expunged. And when I try a similar test with Fastmail.fm (delete the message in Mail, then check using the web interface) the mail is marked as deleted in the web interface and does not show up in Mail.app but the messages are re-numbered appropriately. Granted, I have no idea how Mail.app does its numbering (especially since Thunderbird doesn't have message numbering), but is it possible that there's more information that the IMAP server should be sending back that Dovecot isn't? I've attached a screenshot from my Mail.app that shows the numbering issue. The gaps in the message sequence are where a deleted (but not expunged) message was. jcn

[Dovecot] Mac mail copy/delete problems w/1.0b2

Hi, Mac mail (a horribly mis-behaved client, it seems), has a horribly hard time deleting/copying large blocks of messages from one folder to another. The basic symptom is: 1. Select a bunch of messages 2. Click on delete 3. Wait for a _very_ long time. It also seems very slow on copying, so it may be the "trash folder copy on delete" that is really slowing it down. Anybody else seen this? -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 The best way to have a good idea is to have a lot of ideas.

[Dovecot] Dovecot does not access /var/mail when using Maildir
by mirko＠mirkonet.nl 08 Feb '06

08 Feb '06

Hello, I'm running debain on my machine with postfix, squirrelmail and dovecot installed. Everything works fine and I'm able to access my mail via squirrelmail and via Outlook with imap. However I want to create subfolders what is not possible. After reading I discovered that I use mbox and that maildir is needed in order to be able to use subfolders. I have created a Maildir folder with the maildirmake.dovecot command in my /home/mirko directory and corrected the owner. Now dovecot uses the Maildir and I can create subfolers. However my problem is that I don't receive Emails in my Inbox. Incoming mails are delivered to /var/mail/mirko, but when dovecot uses Maildir it doesn't access this. I have played with the default_mail_env settings in dovecot.conf which does influence the use of mbox or Maildir. However the problem remains: As soon as Maildir is used, the Inbox is empty and I don't receive Email. Is there a way when Maildir is used to point dovecot to /var/mail/ for the incoming Email? Or do I something else wrong? Your help is appreciated. Greetings, Mirko

[Dovecot] How to have a "public" readonly folder?
by Villalovos, John L 08 Feb '06

08 Feb '06

I searched the website and the mailing list and had difficulty finding an answer. I have my email users who are using dovecot-1.0.beta2. I also have setup a dummy account to get the Linux Kernel Mailing List (LKML) traffic. I would like to have it so that my IMAP users (maybe POP3 but don't need that) be able to read the LKML mailing list from that email account. I can put the email into an mbox or a maildir for the LKML mail. I have played around with the namespace and public option and I can't get it to work :( I tried this: namespace public { separator = / prefix = Public/ location = maildir:/home/virtemail/lkml/ } In my email client (Mozilla Thunderbird 1.5), I am unable to view the Public folder. If I select subscribe, I can see the Public folder but it is grayed out. Any ideas? Thanks, John

[Dovecot] Re: MySQL client out of memory error
by Roger Weeks 07 Feb '06

07 Feb '06

Alexander - We had this exact same issue with MySQL authentication. We resolved it by changing this entry in the auth section of the dovecot.conf: # Number of authentication processes to create #count = 1 We set count=20, and then through testing lowered it to count=10. This starts 10 auth-worker processes and to this point we have not had problems with the out of memory condition. -- Roger J.

[Dovecot] Mixed IMAP/POP3 environment: further informations
by Denis Sbragion 07 Feb '06

07 Feb '06

Hello All, some further information. While waiting for some info I'm rolling back to UW and I discovered that if I delete the user "~/Maildir" automatically created by Dovecot, so including any index, the POP3 server works as expected. So it isn't the "Status" flag stored in the mbox file that prevents the download but some status information stored in the IMAP indexes created by Dovecot. I've retried this a couple of times to be sure. Does this helps? Bye, -- Denis Sbragion InfoTecna Tel: +39 0362 805396, Fax: +39 0362 805404 URL: http://www.infotecna.it

[Dovecot] Dovecot index issues (Solaris/Thunderbird)
by Mario Nigrovic-rvvk40 07 Feb '06

07 Feb '06

Folks - My setup is that my mail is filed (by procmail) in ~/.mail/Maildir, an NFS filesystem. But I'm running Dovecot (1.0alpha5) on my local machine (as myself on port 2143), just to serve this mail to my browser (Thunderbird 1.0.2). The NFS data is on a netapp which seems to be creating .nfs files LIKE CRAZY. I expect these are the remnants of lock files, so I'm trying to move my indexes onto local disk. To that end, I've created /var/tmp/mario/dovecot and put the following into my dovecot.conf: default_mail_env = maildir:%h/.mail/Maildir:INDEX=/var/tmp/mario/dovecot Dovecot happily makes index files, but then fails to serve some of my subscribed folders! Thunderbird is less than helpful in telling me what's going wrong, but dtmail shows that dovecot is reporting "out of sync" and a couple other errors (UID out of sequence), then closing the connection (for those folders). This may happen only after Thunderbird has tried to open the folder that I see these errors with dtmail: Dovecot ready. [UNSEEN 227] First unseen. [UIDNEXT 341] Predicted next UID IMAP connection broken (server response) No-op dead stream [CLOSED] No-op dead stream I've turned mmap off and set locking to fcntl. As a last resort, I've turned indexes off default_mail_env = maildir:%h/.mail/Maildir:INDEX=MEMORY but this makes thunderbird reload all headers every time I open a folder, which takes a very long time. Any suggestions? How do I debug this further? Mario

[Dovecot] passwd-userdb with args
by Thomas Wouters 07 Feb '06

07 Feb '06

I'm not sure why the 'passwd' userdb didn't allow args, but it meant (for instance) that the quota plugins weren't usable. I spent quite a bit of time trying to get my new quota-rquotad plugin to work, only to find out that it was my 'quota=rquotad:<filesystem list>' argument that wasn't being passed to the imap child :) The attached patch implements arguments for the 'passwd' userdb, just like it exists for the 'static' userdb (in fact, mostly copy-pasted from 'static'.) It doesn't try to avoid clashing with the values found in the passwd-struct, but I suspect it ends up overwriting them. That could probably be a feature ;) I don't use the passwd-file userdb, but that one would probably also enjoy being argified. -- Thomas Wouters <thomas(a)xs4all.net> Hi!

[Dovecot] dovecot rpms, .subscriptions file, mbox to maildir
by Saurabh Barve 07 Feb '06

07 Feb '06

Hi, I am running dovecot 0.99-14 on a Fedora Core 2 machine. I had a few questions: 1) I wanted to upgrade to the dovecot-1.0 release. However, I am not sure if that's really required. dovecot-0.99-14 has been running very well for me for quite some time. Is there a real advantage to switching to the latest release. The reason I'm asking this is because: i) I don't have too many users to server - around 15 only. ii) My mail server is a pretty fast machine (~1 GHz, 1 GB RAM) machine, so hardware isn't too much of an issue. iii) I like to install software from rpm's. It's not that I can't install from source, but installing from rpm's makes it much easier for me. Just a personal preference. The version of dovecot that I am running was obtained from Dag Wieers web site. I haven't seen a newer version there. I've googled for rpm's for newer versions, and they are available, but I don't want to install it from some third party source that I don't know/trust. iv) I am also planning to support web mail for my users (probably through Squirrelmail). Are there any advantages/disadvantages to upgrading dovecot for that? v) People use Mozilla Mail, Mail.app, Thunderbird, Outlook, and Opera. Does the 1.0 version provide better integration with different mail clients (even though I understand that sometimes it's a problem with the client implementation). So, are there newer version of dovecot (1.0-stable) available in rpm formats which are guaranteed to be safe and un-trojaned? And is there any really good reason why I should upgrade to 1.0-stable? 2) My second question is about creating the .subscriptions (or subscriptions in 1.0) file. When I moved people over from using pine to using a mail client like Evolution/Thunderbird, I had to create .subscriptions/.mailboxlist file for them so that they could see the folders that they had created in pine. However, people still sometimes access e-mail using pine. They then create new folders in pine, which they are unable to see in their mail client. Is there a way around it? This occurs especially when people check their mail at the start of the month, and pine asks about saving/deleting old sent-mail folders, Trash folders. Is there a way to add these folders automagically to the .subscriptions file? 3) Would I be able to support web mail using mailboxes in mbox format, as I have them now? Or do I have to go for Maildir format? Since our university introduced web mail, they have had two sets of folders - one with capitalization (Sent, Deleted Messages, etc.) and one without (sent-mail, etc. - these were from our pine days). Is this due to web mail? Also, if I do need to convert from mbox to Maildir, what is the standard tool for doing that? I saw at least three different tools/scripts for doing that (mbox2maildir,mb2d,mb2md-2,mb2md.pl, .. ). Which tool (and from where) should I use to convert mailboxes without problems? Any help is greatly appreciated. Thanks in advance, Saurabh. ----- sa(a)atmos.colostate.edu

There was a patch posted to fix dotfile folder names in this mail: http://www.dovecot.org/list/dovecot/2005-July/008127.html I have a web mail client (which stores preferences in a dot-file/folder through IMAP) and pine users (address book is a dot-folder in IMAP) that this affects. I can certainly hand-apply the patch, but I'd feel a lot more comfortable if this had some future in the real source. -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 I have earned my disillusionment.

[Dovecot] Newbie question

Hi, Finally I managed to build (as ordinary user in my home dir) 1.0b2. (remember, I had problems with db-ldap.h disappeared after compile) What is the (simplest and) safest way to shut down dovecot on the live server and replace the running 0.99.14? I run OpenBSD 3.7 on Sparc. The last step would be 'make install', of course. To shutdown dovecot the last time I resorted to kill processes but I felt I had missed something... the install page (http://wiki.dovecot.org/BasicInstall) says to kill it, it feels a little crude; no nicer signals to send?

[Dovecot] Panic: key not found from hash

[Dovecot] Mixed IMAP/POP3 environment and message status flags
by Denis Sbragion 06 Feb '06

06 Feb '06

Hello All, I'm trying to migrate from UW Imap to Dovecot (latest 1.0 beta 2). The target is to go from the actual environment (Eudora + POP3) to a web based IMAP environment (IMAP + SquirrelMail). While migrating we will need to keep both environments for some time, with users having both the ability to use Eudora through POP3 while in the office and also the ability to check e-mail using the web based interface from time to time when they are out of office. Everything seems to work pretty well except for one little quirk. Whenever new mail messages are checked on-line through IMAP they are marked with "Status: O" or "Status: RO" in the main INBOX file (which is kept in the old mbox format now, and is one of the many reasons for the Dovecort choice). This is correct following the RFC standards but after that the POP3 server seems to completely ignore any message marked as "O" or "RO", making it impossible to download previously seen/read messages through Eudora. I've checked any available Eudora and Dovecot setting, including the pop3_no_flag_updates flag, but so far nothing worked. Looking at mailing list archives it looks like this behaviour is intentional and has been introduced to work around some problems with Eudora when the "Leave mail on server" option is enabled. Nevertheless it seems there's still something wrong. UW Imap seems to get this right, it lets Eudora download the already read message, which are correctly downloaded already marked as read. I haven't been able to identify the source of the problem, i.e. if it is either an Eudora problem which UW circumvent in some way or a real Dovecot problem. I'd really like to move to Dovecot, which provides many feature which are really useful for our situation, expecially maildir folders, which are fast and much more "differential backup" friendly than single file mailboxes. Unfortunately this IMAP/POP3 interaction problem would be a major showstopper because it will prevent a smooth migration from the old environment to the new one. Any hint about this issue? Anybody faced a similar problem so far? Thanks in advance for any help, and my compliments for the excellent job performed so far. Dovecot seems to be the right tool to fill the gap between the simpler UW and the Cyrus monster. Keep on going! :) Bye, -- Denis Sbragion InfoTecna Tel: +39 0362 805396, Fax: +39 0362 805404 URL: http://www.infotecna.it

[Dovecot] vpopmail authentification broken in dovecot 1.0beta
by daniel petre 05 Feb '06

hello, i got * net-mail/dovecot Latest version available: 1.0_beta2 Latest version installed: 1.0_beta2 Size of files: 1,309 kB Homepage: http://dovecot.org/ Description: An IMAP and POP3 server written with security primarily in mind License: LGPL-2.1 and since dovecot-0.99.14-r1 authentification doesnt work no more. i posted something similar with dovecot-1.0_alpha5 but all the answers i got were like "it isnt dovecot's fault, its vpopmails". bummer, my vpopmail did not changed , but dovecot versions yes. so i think dovecot is broken with vpopmail auth. i edited dovecot.conf and enabled all the parts related to vpopmail correctly like in old dovecot.conf here's what i receive in the log: dovecot: Jan 31 14:51:28 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=81.18.x.x rip=81.18.x.x resp= dovecot: Jan 31 14:51:28 Info: auth(default): client out: CONT 1 dovecot: Jan 31 14:51:28 Info: auth(default): client in: CONT 1 AGRhbmlAbGlgudXhzb2x1fdGlvbnMucmh8AcG9jcG9j dovecot: Jan 31 14:51:28 Error: auth(default): vmysql: sql error[3]: MySQL server has gone away dovecot: Jan 31 14:51:28 Info: auth(default): vpopmail(dani(a)domain.ro,81.18.x.x): unknown user dovecot: Jan 31 14:51:29 Info: auth(default): client out: FAIL 1 user=dani(a)domain.ro dovecot: Jan 31 14:51:29 Info: auth(default): client in: AUTH 2 PLAIN service=POP3 lip=81.18.x.x rip=81.18.x.x resp=AGRhbmlAbGlgudXhzb2x1fdGlvbnMucmh8AcG9jcG9j dovecot: Jan 31 14:51:29 Error: auth(default): vmysql: sql error[3]: MySQL server has gone away dovecot: Jan 31 14:51:29 Info: auth(default): vpopmail(dani(a)domain.ro,81.18.x.x): unknown user dovecot: Jan 31 14:51:31 Info: auth(default): client out: FAIL 2 user=dani(a)domain.ro i tried compiling dovecot with and without mysql support and the log is the same. vpopmail support is compiled in. so i use only vpopmail auth, no passdb, no mysql, no ssl. anyone can help with this error? coz dovecot seems such a nice imap/pop3 daemon but so much broken since last 0.9 version which is a shame.. thank you. -- Daniel Petre System Administrator Tech Support Coordinator .............................................................................

[Dovecot] default_mail_env auto-detect woes for maildir users
by David Friedlander 05 Feb '06

05 Feb '06

Hello-- I am a fairly new dovecot user and have run into a problem. I am running dovecot 1.0alpha5 (built from source) on a Fedora Core 1 machine. The system has about 400 users with over 80 IMAP users, and we have just transitioned from UW-IMAP. Thus all users are currently still mbox users. I would like to transition them to maildir users (this was the main point for me switching servers), and I chose dovecot because it could simultaneously support both formats. My dovecot.conf uses auto_detect (no default_mail_env defined, by choice). Auto-detect is working fine for mbox users, as shown by this (edited) log snippet: dovecot: imap(janeuser): maildir: couldn't find root dir dovecot: imap(janeuser): mbox: root exists (/Home/janeuser/mail) dovecot: imap(janeuser): mbox: INBOX exists (/var/mail/janeuser) dovecot: imap(janeuser): mbox: root=/Home/janeuser/mail, index=/Home/janeuser/mail, inbox=/var/mail/janeuser However, for another user who already has ~/Maildir and a proper maildir-format spool location ( /var/mail/joeuser/{cur|new|tmp} ) the log shows: dovecot: imap(joeuser): maildir: root exists (/Home/joeuser/Maildir) dovecot: imap(joeuser): maildir: root=/Home/joeuser/Maildir, index=/Home/joeuser/Maildir, control=, inbox= (Mail clients show no messages, but one can see them from the UNIX shell and with mutt on the server.) If I set default_mail_env = maildir:~/Maildir:INBOX=/var/spool/mail/%u then everything works fine for 'joeuser'. However, I need auto-detect during this transition phase. My questions, please: * How do I get INBOX ("inbox=") to be properly defined/detected? * Must I do this with namespaces, and how does that affect the fact that there will be a transition period where some users use mbox and others use maildir? * Other advice? I have been unable to track this down so far, between reading the Dovecot documentation and Googling the dovecot mailing list archives. Thanks in advance, David

[Dovecot] Support for Kmail maildir format
by Graham Cobb 04 Feb '06

04 Feb '06

Has anyone looked into providing support in dovecot for Kmail folders? I would like to make my Kmail folders (on my main desktop system) available to my other systems (including over a VPN when I am travelling). Kmail is my main mail program and I have a lot of mail in a lot of folders, so I don't want to set up a separate IMAP service and move all the mail and folders. Kmail's use of maildir seems to folow the basic maildir approach except that sub-folders are handled differently. If you create a folder (say it is called ABC) in Kmail and start putting mail in it, Kmail creates a directory on the disk called ABC (not .ABC) and creates the cur, new and tmp folders within it to contain the email. If you then create a subfolder of ABC (say it is called DEF, contained within the ABC folder), Kmail creates a directory on the disk called .ABC.directory and creates the DEF directory within that. In other words, maildir directories are given the same name as the mail folder (with no leading dot) but sub-folders are contained in disk directories called .<folder-name>.directory. I have taken a quick look at the dovecot code and am fairly sure this could be handled by a variant on the existing maildir code (e.g. by changes to maildir_fill_readdir and other routines). Has anyone tried this? Graham

[Dovecot] rquotad (NFS) quota plugin
by Thomas Wouters 03 Feb '06

03 Feb '06

The attached patch is an updated version of my quota-rquotad patch for the quota plugin. Like quota-fs, it only does quota reporting, not enforcing or changing. It also only works on FreeBSD, and possibly other *BSD's. It lacks any and all configure-time tests to see if RPC is even supported, and hardcodes the (Free)BSD way of getting at the NFS server of an NFS mount. I'm mostly mailing it around to avoid duplicate work, in case anyone is looking for it. I do intend to generalize the plugin-patch, and add proper configure checks, I just haven't gotten around to testing it on other BSD systems. Linux support would be nice, but getting at the NFS server of an NFS mount is apparently quite a hassle, as it means reading /etc/mtab or /proc/self/mounts. Yuck. -- Thomas Wouters <thomas(a)xs4all.net> Hi! I'm a .signature virus! copy me into your .signature file to help me spread!

[Dovecot] mbox to maildir conversion on a user-by-user basis!
by Tony Kay 03 Feb '06

03 Feb '06

In the midst of evaluating Dovecot for use in solving some mbox locking issues (while also waiting for our eventual migration to maildir), I had an epiphany. It looks like Dovecot's auto-detection of mail formats would allow us to migrate from mbox to maildir on a user-by-user basis! I was thinking: 1. Let dovecot autodetect mail storage 2. Use some procmail trickery to detect which format to deliver into (I am researching how to do the detection on a user-by-user basis) 3. Manually convert users as you want by: - Temporarily disable mail delivery for that user (at least make it look like the inbox is locked) - Run conversion on mbox files -> maildir format - Put in the procmail hack for them - Re-enable delivery Way cool. I am still working out the details, but I was wondering if anyone sees a problem with this??? -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Sanity is a cozy lie.

[Dovecot] not creating homedirs when using maildir format
by Ben Halicki 03 Feb '06

03 Feb '06

Hi all, I'm in the process of setting up dovecot, but for some reason, it's not creating home directories if they don't already exist. I have the following line in dovecot.conf: default_mail_env = maildir:~/mail:INBOX=/var/mail/%u I have set permissions on /home to allow everyone full access, so creating directories in /home by dovecot non-root processes shouldn't be a problem. If I instruct dovecot to use mbox format, directories are created without a problem. The problem only seems to exist with maildir. Any help would be greatly appreciated!

Never done this, ISTR there is a PAM module that is supposed to do this (create the directory). It would require you to use PAM, obviously. -- Matthias Andree Thanks for the reply Matthias. Only problem with PAM and pam_mkhomedir, is that Dovecot doesn't seem to open a session, so pam isn't called and pam_mkhomedir doesn't get the chanceto create a home directory.

I could _not_ make dovecot misbehave on NFS w/two physical servers accessing the same mailbox.

UW uses a "kiss of death" signal for collaborative locking...the mtime changes are all assumed to be appends as far as I know. The problem (which I can reproduce) comes with a situation like this: - IMAP host A and B access INBOX for the same user from different physical servers which share the inbox via NFS - Neither sees the other (because UW imap assumes lingering opens come from c-client apps, and it uses signals/flock/tmp to sync them, which are not available when A and B are on separate hosts). - Delete and expunge a message on B - 'A' can still read the expunged message. - Mark two messages for delete on A, including the one previously expunged by B - New message delivered to inbox (possibly by yet another host) - Expunge on A - New message is lost My theory is that the two IMAPs are both holding a fd open, and this causes one of the copies to become stale (in the sense it no longer has a filesystem name). The new mail is delivered to the non-stale box, and then the expunge on 'A' causes the stale open file to be "rewritten" over the top of the non-stale one. Result: mail loss. We also see things like message flags that magically reset themselves, etc. I did some testing w/dovecot 0.99 earlier in this same config, and it seems like it has some issues. For example a delete/expunge on IMAP A was "sort-of" seen by the B (fetch complained that the UIDs had changed, and would not work until a NOOP was done...this is technically OK), but B magically restored the deleted message with a new UID (which is not so good, since a client that caches stuff may now have a strange view of the world...I need to examine the set of "update" notices that went along with these events to better understand the implications). This also worries me because the "magic" reappearance indicates a copy from a stale fd, which could exhibit the same mail loss I produced w/UW IMAP. I am planning on updating to your latest source tree tomorrow (I am out of time today), and see if I can make it "lose" new mail. Opinions??? Thanks! Tony

[Dovecot] extremely slow delete/move operations?
by Gregory K. Ruiz-Ade 01 Feb '06

01 Feb '06

I've been working to migrate several hundered users on to our new mail servers, which run dovecot 0.99.11 (RHEL4). The problem I'm seeing is that deleting or moving a message seems to take a very long time. It's not uncommon for Thundirbird (1.0.7) to have delays of 5-10 seconds to delete a single message from my Inbox (<500k) and place it in my Trash folder (~100MB right now). The systems are Dell PowerEdge 1850 (dual 3.6GHz Xeon) with two 300GB SCSI drives in a hardware mirror. Filesystems are ext3 on LVM. Inboxes are on /var/spool/mail (/export/mail, symlinked into /var). User mail folders are in their home directories (/export/homes1/<user>, automounted to /home/<user>; some home directories are NFS automounted from a NetApp). Both the mail spool and home directories are available over NFS for compatibility reasons with the former setup. What's really bugging me is that I've used the same software (RHEL4 and dovecot 0.9x.x) at my last workplace, and the performance was outstanding; it beat UWIMAPd hands-down, especially with large mailboxes. Here, the opposite seems to be true. The primary difference seems to be that we're using NFS here, but I wasn't using NFS at my last job. I'm getting a lot of grief over the delays when users delete mail or move mail from their inbox to one of their mail folders. Enough so that they're now resisting moving to the new server. Where do I look to find out what's causing the slowness? What can I do to make it faster? Mailbox formats are mbox. Using these options in /etc/dovecot.conf: ----- protocols = imaps pop3s imap_listen = [::] pop3_listen = [::] ssl_cert_file = /usr/share/ssl/certs/csefast.ucsd.edu_cert.pem ssl_key_file = /usr/share/ssl/private/csefast.ucsd.edu_key.pem login_dir = /var/run/dovecot-login login = imap login = pop3 verbose_proctitle = yes first_valid_uid = 100 default_mail_env = mbox:~/:INBOX=/var/mail/%u mail_full_filesystem_access = yes mbox_locks = dotlock fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root ----- Thanks in advance, Gregory -- Gregory K.

I.e. how would one dovecot IMAP on server A detect that dovecot on server B had rewritten something like flags on the mailbox they are both accessing? I'm sure it doesn't leave the dot lock sitting around, since that would block mail delivery. It just checks if mbox's mtime has changed. If it has, it checks if there are new mails or if it needs to do some other synchronization (mbox_dirty_syncs / mbox_very_dirty_syncs causes it to delay it as long as possible). UW-IMAP also checks if mtime has changed, but instead of trying to figure out what changed it just disconnects the client with an "unexpected mbox change" error.

[Dovecot] Immutable Maildir (or: "I know drag&drop")
by Michael Renner 31 Jan '06

31 Jan '06

Hi, I'm 'constantly' (every odd month) faced with users happily dragging around or (un)subscribing folders in our shared IMAP account. Is there a "clean" way to prevent users from doing that when having a Maildir? Unix permissions probably won't cut the slack since setting any Maildir (sub)directory to readonly (immutable or chmod u-w ) will probably cause dovecot to hit a wall at high speed sooner or later (lock files, rotated cache/log files) Got any other ideas? best regards, Michael Renner

[Dovecot] Question about Dovecot and NFS
by Tony Kay 31 Jan '06

31 Jan '06

Hi, We are using mbox and UW IMAP, and are having issues because UW IMAP does not support multiple client access when you use NFS for the mail files. I've done some research (see the comments after my 2 questions below), and most of the other major IMAP servers simply don't support it (courier is about the only one that has a positive comment). How much testing have you done w/NFS-mounted mail in mbox format? Have you found a reliable way to handle NFS mbox files? The UW IMAP docs say that multiple client access to mail spools that are NFS mounted is not safe, and the source has comments like this about NFS mail spools: /* Make fcntl() locking of NFS files be a no-op the way it is with flock() * on BSD. This is because the rpc.statd/rpc.lockd daemons don't work very * well and cause cluster-wide hangs if you exercise them at all. The * result of this is that you lose the ability to detect shared mail_open() * on NFS-mounted files. If you are wise, you'll use IMAP instead of NFS * for mail files. * * Sun alleges that it doesn't matter, because they say they have fixed all * the rpc.statd/rpc.lockd bugs. This is absolutely not true; huge amounts * of user and support time have been wasted in cluster-wide hangs. */ Cyrus' FAQ says this about NFS mail spools: (http://asg.web.cmu.edu/cyrus/imapd/install-FAQ.html#nfs) NFS (don't) Q: Weird things are happening. The mailspool is mounted over NFS, and... A: Don't mount the mail spool over NFS. Due to locking problems with NFS, this doesn't work (and for various other reasons, probably isn't worth the bother; IMAP appears to be I/O bound, not CPU bound, and scaling in this way is not a good idea). More specifically, if you use NFS and it looks to work, you may have locking problems in the future which will result in silently lost mail. If you use NFS and things go berzerk, it's because mmap(2) apparently has different semantics on local disk than it has on NFS. You can get the above behavior (silently lost mail) if you work at it. Courier is the only one that seems friendly (excerpt from their web site): Courier-IMAP is popular on Qmail/Exim/Postfix sites that are configured to use maildirs. The primary advantage of maildirs is that multiple applications can access the same Maildir simultaneously without requiring any kind of locking whatsoever. Maildir is a faster and more efficient way to store mail. It works particularly well over NFS, which has a long history of locking-related woes. -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 When they discover the center of the universe, a lot of people will be disappointed to discover they are not it.

[Dovecot] worth a few Euros?
by -- -- 31 Jan '06

Yo Timo, did you say that login processes "just don't crash"? Found these while doing load/malformed data tests. Got the kernel patch allow_setid_cores working. Don't have time to check if they're exploitable. Probably time to get a gamma version out for people, eh? Cheers, Jared :) =========================================================================================== Note: Running dovecot-1.0.beta2 with simple (no funniness) config Note: Running on Intel (in VmWare) with RH9. Note: I'm using shadow authentication, but tried with PAM and it still dumped. Note: For this first core, I see the server responding with: "*OK Waiting for authentication process to respond.." Note: Not sure, but I think these problems are timing related. Be sure to check if a pointer is valid and that will get rid of most of these. Note: I have plenty of sample cores if you need one to fix. -Jared DeMott [root@server dovecot]# gdb ./dovecot-auth -c core.22753 GNU gdb Red Hat Linux (5.3post-0.20021129.18rh) Copyright 2003 Free Software Foundation, Inc.
