[Dovecot] dovecot -CVS and epoll and cvs not building
by Reuben Farrelly 22 Dec '05

22 Dec '05

Hi, After reviewing my dovecot ./configure options I thought I'd give --with-ioloop=epoll a go again (as opposed to just using =poll) but I'm seeing some errors appearing in the maillog that aren't there with standard poll: Dec 23 02:34:47 tornado dovecot: imap-login: Login: user=<reuben>, auth-method=plain, remote=220.237.24.149, TLS Dec 23 02:34:48 tornado dovecot: imap-login: io_loop_handle_add: epoll_ctl(3, 9): No such file or directory Dec 23 02:34:48 tornado dovecot: child 16524 (login) returned error 89 They're appearing fairly frequently, ie within a few mins of starting up and then the message won't go away until the client is restarted. So it's easy to reproduce but I'm not sure how to go about debugging it. Can anyone help with this? It's a very recent Linux-2.6 system so epoll support should not be an issue. Additionally -CVS won't compile for me right now, it bails out when compiling the 'quota' plugin. Workaround is to manually edit the dovecot/src/plugins/Makefile and not build this plugin.. Timo - is there a file/commit missing from -CVS at the moment for this plugin? I see no other reference anywhere for dqb_curblocks in the code. gcc -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../../src/lib -I../../../src/lib-dict -I../../../src/lib-mail -I../../../src/lib-storage -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/usr/kerberos/include -MT quota-fs.lo -MD -MP -MF .deps/quota-fs.Tpo -c quota-fs.c -fPIC -DPIC -o .libs/quota-fs.o quota-fs.c: In function 'fs_quota_get_resource': quota-fs.c:208: error: 'struct dqblk' has no member named 'dqb_curblocks' make[1]: *** [quota-fs.lo] Error 1 reuben

[Dovecot] Migrating from mbox to maildir, which converter is compatible with dovecot
by Oliver Schulze L. 22 Dec '05

22 Dec '05

Hi, I'm testing/debuging the migration from mbox to maildir in a mailserver running Dovecot 1.0alpha5. I migrated all 472715 emails(in a test server) and later noted that dovecot could not get the same flags/status of the emails as in the mbox. I was using perfect_maildir.pl and I think its not dovecot fault. Seems to me that perfect_maildir.pl convert the emails in a way that dovecot could not understand completelly. So, my cuestion is, which mbox to maildir converter can I use that is compatible with dovecot 1.0alpha5 ? Thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] mailbox from ldap and indexes
by Stian Jordet 21 Dec '05

21 Dec '05

Hi, because of quota, I would like to have indexes on another filesystem then user's maildir. This I can do with "default_mail_env= maildir:/% h/Maildir:INDEX=/var/indexes/%u" or something. But when I get the users mailbox location from ldap, there is no way to set the index? I guess I can make the ldap entry contain the INDEX as well, but I would like to use the ldap entry in the exim conf as well, to tell exim where to write the mails... Is there a way I haven't thought of yet? I have this in dovecot-ldap.conf now: user_attrs = uid,homeDirectory,mailbox,uid,uidNumber,gidNumber If I could do something like: user_attrs = uid,..,"maildir:" . mailbox . ":INDEX=var/indexes/%u",... that would have been awesome. Best regards, Stian

[Dovecot] Another "Too many files open" post
by Andy Cravens 21 Dec '05

21 Dec '05

I'm running Solaris 9 Sparc with Dovecot alpha 5 and using maildir format.. I noticed in the log file the following error: dovecot: Dec 20 15:54:18 Error: imap(xxxxxxxx): open(/export/home/xxxxxxxx/mail/.Sent Messages/cur/1135013649.002916.mbox:2,Sab) failed: Too many open files I called the guy and asked him what he was doing... synching his folders. It hung for a while but finally finished. I searched the archives and found some related info from Jeff Ballard: >Actually on Solaris 9 you want to put something like this in >/etc/system: > >set rlim_fd_cur = 32768 >set rlim_fd_max = 65536 > >That sets the current fd's to 32k and max to 64k. Unfortunately, to >take effect you'll need to reboot. After the reboot, ulimit -a should >show that nofiles(descriptors) is 32768. > >-Jeff And I found this from Jeff Earickson: >I ran into this problem with alpha4 on Solaris 9. I doubled the >following dovecot settings: > >login_max_processes_count = 256 (was 128) >login_max_logging_users = 512 (was 256) > >and the problem went away. I carried these numbers forward intoalpha5, >and it has been working fine. I changed my /etc/system file but have not rebooted yet. Also, on Jeff Earickson's post, I looked at my dovecot.conf settings and they're basically default which means everything in the "Login processes" section is commented out. I have 10 users on this system and will hold off migrating any more until I can resolve this problem. By the way, my "ulimit -a" shows "open files" at 256 which seems low. # ulimit -a core file size (blocks) 0 data seg size (kbytes) unlimited file size (blocks) unlimited open files 256 pipe size (512 bytes) 10 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 29995 virtual memory (kbytes) unlimited Any advice would be appreciated. I can't reboot for a few more days.

[Dovecot] 1.0 alpha5: Plugin woes: quota/trash
by Jan-Piet Mens 21 Dec '05

21 Dec '05

Hello, I'm running Dovecot v1.0.alpha5 and I'm trying to get the quota plugins to work. I've enabled modules in dovecot.conf, but when the IMAP connection is opened, the log shows undefined symbols. : Loading modules from directory: /usr/local/lib/dovecot/imap : dlopen(/usr/local/lib/dovecot/imap/libtrash_plugin.so) failed: /usr/local/lib/dovecot/imap/libtrash_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libimap_quota_plugin.so) failed: /usr/local/lib/dovecot/imap/libimap_quota_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libquota_plugin.so) failed: /usr/local/lib/dovecot/imap/libquota_plugin.so: undefined symbol: dict_transaction_commit The source shows that the modules are read by reading the module directory and loading each of the found .so files. Supposing that the ordering of the files in the directory is wrong, I've even recreated the module directory manually, copying the libs into it in different orders; no change. It seems to me as though there are cross-dependencies in the shared libs that cannot be resolved. Has anybody found it to work or could anyone give me a hint on how to get it working? Thanks & regards, -JP

[Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 20 Dec '05

20 Dec '05

Hi, I'm having trouble as of about noon today. I noticed I wasn't getting any new messages in Thunderbird. I restarted it and still nothing. I looked at the log, and found nothing from dovecot for a long time (since perhaps noon today). I restarted dovecot, but still it didn't get me new mail. I finally removed dovecot.* in my Maildir folder and restarted dovecot. I'm using 1.0alpha4. Now I'm still not able to get the new mail, and I get the following messages: Nov 20 20:49:59 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=plain, rip=172.17.128.191, lip=10.7.3.11 Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): Effective uid=501, gid=20 Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): maildir: data=/Users/frohro/Maildir Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): maildir: root=/Users/frohro/Maildir, index=/Users/frohro/Maildir, control=, inbox= Nov 20 20:50:00 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2578 > 2566) Nov 20 20:50:00 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2578 > 2566) Nov 20 20:50:08 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:25 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=plain, rip=172.17.128.191, lip=10.7.3.11 Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Effective uid=501, gid=20 Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): maildir: data=/Users/frohro/Maildir Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): maildir: root=/Users/frohro/Maildir, index=/Users/frohro/Maildir, control=, inbox= Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:26 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) I guess I won't be able to read any answers to this in my mailbox, but I should be able to read the archive on the web.

[Dovecot] Auto-expunge
by John Newman 20 Dec '05

20 Dec '05

Hi, For some time we've been intermittently experiencing a problem whereby dovecot often automatically expunges "deleted" messages. This has happened across several mailboxes. The problem is proving difficult to isolate as it's seemingly non-deterministic in nature. One commonality, however, is that the "auto-expunge" seems to occur with greater frequency on mailboxes with a larger of deleted messages. First off, does this sound any alarm bells for anybody else? Perhaps others have encountered this in the past? I've trolled the mailing list (and web) but cannot find any references to this occurring elsewhere. Additional Information: We have experienced this "bug" in 1.0-alpha3 and alpha4. Underlying dovecot we have a maildir, populated via Perl's Mail::Box::Maildir module. Many thanks for any assistance that can be offered. John.

If its too hard for them to setup the pop3 catch all, we can probably put some mapping in place to smtp froward mail to their server. This is more complex on our part so would prefer not to do it that way, but its an option and will require not setup on their part other than make sure their server does not accept mail for anyone other than our server. dovecot-request(a)dovecot.org wrote: > Send dovecot mailing list submissions to > dovecot(a)dovecot.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://dovecot.org/cgi-bin/mailman/listinfo/dovecot > or, via email, send a message with subject or body 'help' to > dovecot-request(a)dovecot.org > > You can reach the person managing the list at > dovecot-owner(a)dovecot.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of dovecot digest..." > > > Today's Topics: > > 1.

[Dovecot] Two-phase delete/expunge ?
by Jan-Piet Mens 16 Dec '05

16 Dec '05

Is it possible to have messages which have been marked for deletion or which are to be expunged, moved into a "secret" directory on the IMAP server? The IMAP client would consider the message as deleted, but an administrator could easily restore single messages (without having to retrieve tapes) by moving the message back into inbox. I understand there are patches floating around somewhere enabling that for Cyrus, but I'd love to see Dovecot do that as well. Is anyone aware of such functionality? Thanks, -JP

[Dovecot] strange connection NG
by Yi Xuan 16 Dec '05

16 Dec '05

Dear all, I have a devocot server based on fedora core 3 in Japan. When my users are in Japan, there is no any problem reported.Devocot works very well. But when my users are in China, sometimes the following problem occured. Sometimes the user can not download mails, after that all connections attempt to server(e.g http/ssh) failed. the user has to close OutLook, and wait for about 10 minutes, then access the webmail to read mail. Maybe the POP NG is due to the network , but what is the possible reason of 10-minute other connection NG? Is there any solution? Because users in China share the same outside IP, when one user occures POP NG, all users occures server access NG, that is a big puzzle. Thanks in advance. Best regards,

[Dovecot] 1.0alpha5 released
by Timo Sirainen 16 Dec '05

16 Dec '05

We have now some new big features: - Beginnings of dbox mailbox format. It should work, but if you happen to delete/break index files, the mails aren't found again. So really not a good idea to use it for more than testing. - GSSAPI (Kerberos 5) support by Jelmer Vernooij with some fixes by pod(a)herald.ox.ac.uk - Added dictionary API to Dovecot, similar to what Postfix has. It can be used for getting/setting key=value pairs, which can be useful for many different purposes. For example it could be used to store mailbox metadata for ANNOTATEMORE extension. Implemented SQL backend for it. In future there should be berkeley DB backend at least. Also there could be some kind of proxy backend which would use UNIX socket to connect to dictionary server doing the actual work. This way each imap/lda process wouldn't have to connect to SQL server themself. - Quota plugin is now included. We also have now dictionary based quota support, which means the quota limits and values can be stored in SQL. However I haven't actually tested these changes yet, so there's a good chance the quota plugin doesn't actually work at all. - Created a new trash plugin which works only together with quota plugin. The point of it is to expunge mails from a list of configurable mailboxes whenever saving new mails would cause the account to go over quota. The oldest mails are expunged first, and only as many mails are expunged as is needed to save the new mail. For configuration it first looks up for ~/.dovecot.trash.conf, and then fallbacks to /etc/dovecot-trash.conf. The file format is "<priority> <mailbox name>". It's possible to have multiple mailboxes with same priority. Lower number = higher priority. This plugin is also currently untested. The plugins are currently installed as shared libraries to plugin directory. At some point I'll add a configure option to select which plugins to compile directly into binaries. Possibly even do it by default for some plugins (quota). And smaller new features: - If LDAP lookup fails because connection gets closed, try retrying it again after reconnect. This is however untested, hopefully didn't break LDAP code completely.. - %w variable in dovecot-auth contains password. Can be used to do eg.: password_query = select null as password from users where userid = '%u' and password = password('%w') - syslog_facility setting And fixes: - auth_cache was quite broken - adding keywords caused sometimes assert-crash - If login_greeting_capability = yes we could have sent the capability before dovecot-auth returned what auth mechanisms were available, forcing clients to use plaintext authentication - Lots of mbox fixes again.. - userdb prefetch wasn't supposed to be uncommented in dovecot-example.conf in alpha4. Comment it out if you don't need it. - Don't crash with "out of memory" in 64bit systems - IDLE command might have crashed when finishing itself if there were lots of external changes - pop3_reuse_xuidl setting wasn't actually working

I've seen this was mentioned before but remains unsolved. I upgraded Dovecot from 0.99 to v1.0.alpha4 yesterday and it rendered my inbox inaccessible: Dec 15 00:09:07 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/.imap/INBOX/dovecot.index: messages_count too large (1121 > 1115) I've since moved that inbox away so I can view my new mail again. The error has moved with the mbox file: Dec 15 00:27:41 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/old-inbox/.imap/200407-200512/dovecot.index: messages_count too large (1121 > 1115) Dec 15 00:27:41 sand dovecot: child 83886 (imap) killed with signal 11 This is on FreeBSD 4.8 (yes, yes ... but: "up 687 days" which is quite nice) all running on local disk. So earlier suspicions about NFS or MacOS X are out of the window. One day I'll move move from mbox to dir format and the problem will go away, in the meanwhile, I thought it would be good to resolve this issue. Let me know how I can help to get to the bottom of this. - mo

[Dovecot] Best way to upgrade from 1.0a4 to 1.0a5
by Cliff Hayes 16 Dec '05

16 Dec '05

Hello all, I have 1.0 Alpha 4. Is it better to shut down sendmail, uninstall dovecot 1.0a4 then install 1.0a5, or just install 1.0a5 over the top of 1.0a4? Thanks, Cliff

[Dovecot] Variable '%r' doesn't transfomr in Postgres query
by Sebastjan Trepca 15 Dec '05

Hi, i'm using postgres for authorization. When I switched from a4 to a5 authorization stoped working. Query in conf file for postgres looks like this: password_query = select password from auth('%u','%r'); But in logs, the transformed query looks like this: Performing query: select password from auth('test','%r'); Looks like you don't transform that remote IP parameter?

[Dovecot] writing an MDA, help me avoid corrupted indexes
by Lee Howard 15 Dec '05

15 Dec '05

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes the mail off to SpamAssassin. From there I need an MDA to dump any mails detected as spam into a common spam folder, discard any mails with viruses (antivir) and send a notification to me, and then drop good mail into the appropriate maildir directory for the virtual users to get via both POP3 and IMAP. I could conceivably use procmail to do that MDA, and I've done similar things with procmail in the past, but my growing experience with procmail indicates that procmail is too ferocious for what simple work I need done, and too difficult to make work right in a virtual-user environment. So I've written my own little MDA with a few lines of shell that will take the mail from Postfix+SpamAssassin and ultimately deposit mails in the maildirs. So far so good, except that I keep seeing corrupt indexes... probably because I'm not touching the indexes at all with the MDA. My guess is that in order for the MDA to properly deal with maildir it needs to adjust the indexes after depositing new mail. Okay. So can someone either give me a pointer to the proper documentation on this, including the index file formats, or perhaps just explain it to me? Maybe I'm missing a larger picture of maildir handling? I've glanced through http://www.dovecot.org/doc/index.txt but I notice that the index files are not ASCII, so I'm not sure where to start at understanding that documentation. Any and all help would be appreciated. Thanks, Lee.

[Dovecot] assertion failed: (conn->refcount > 1)
by David Schweikert 15 Dec '05

Hi, Sometimes (happens maybe twice in a day), I have the following errors: Dec 15 16:10:17 dovecot: auth(default): file auth-client-connection.c: line 33 (auth_client_send): assertion failed: (conn->refcount > 1) Dec 15 16:10:17 dovecot: child 17152 (auth) killed with signal 6 Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dovecot seems to recover though, because afterwards it still works. I did however notice that the logging-in seemed to hang for a while (some seconds).
