[Dovecot] 45second delays on log in
by Ben Marsh 14 Nov '06

14 Nov '06

Dear List Members, We have been running Dovecot as an IMAP server for web based access to email for our customers. At the moment, when the server is under load, some users are finding that it takes 45 seconds to log in. I was wondering if any of you guys would have any tips. I would love any information that would help solve or debug this issue. Background information: The server is Debian with kernel 2.4.31. We are running Dovecot 1.0rc6. I have reviewed the change logs and not found any changes pertinent to our situation from rc6 to rc14 (But maybe I am wrong). We have our own auth mechanism. This auth mechanism is the same used across our other products and we haven't had the same delays with the other products. From the information in the various log files the auth mechanism responds almost instantaneously but it still takes a long time for 1 OK Logged in. message to arrive on the screen when using telnet localhost 143 to login. All the mailboxes are stored over NFS. I have taken the step of moving the INDEXES from NFS to a local hard drive using default_mail_env = maildir:%h/mail:INDEX=/spare/%h in the config file. (/spare is a locally attached hard drive). We are using Maildir for our mailboxes so I am told that locking should not be a problem. A mailbox would never be accessed by two machines simultaneously due to the architecture of the system. In order to gain performance increases we also implemented an IMAP proxy between the webmail client and the imap server. This removes delays in all but the first attempt to access webmail. When logging into a user for which login has been verified to take about 45seconds deletion of the large numbers of messages seemed to speed up login for that particular mailbox indicating to me that it was other things that dovecot does after login and before the 1 OK Logged in. message is displayed that takes up all the time. Unfortunately this theory failed when I tried it with other users. I have also analysed the log files. of the 100,000 lines in the log file 49 were messages: Child 12040 (login) returned error 89 54 were messages: imap-login: Master sent reply with unknown tag 18 The actual number at the end of the message changes lots. The frequency of the extended logins would make it extremely unlikely that these messages are the problem. Any help is very much appreciated. Thanks, Ben Marsh

[Dovecot] Question regarding bounce messages on quota full.
by Mustafa A. Hashmi 14 Nov '06

14 Nov '06

Hi all, Using dovecot's LDA (debian backports package: 1.0rc2), users who have exceeded their quota when receiving messages see the message get bounced. This works fine for us, however, the sender is sent a message as follows: -- Start bounce text ERROR This is the Postfix program at host foo.domain.com I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <user(a)foo.domain.com>: Command died with status 11: "/usr/lib/dovecot/deliver" -- End bounce text Is it not possible to specify something a bit more civil for the sender? a "User is over quota" message works much better here. We're already running a script which notifies users when they approach a certain specified % that they're about to exceed quota, however, hoping they all comply is another thing entirely. Any assistance would be much appreciated. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com mh(a)stderr.net

[Dovecot] NTLM authentication from Outlook
by Lars Skovgaard 14 Nov '06

14 Nov '06

Hi all I've enabled ntlm authentication in dovecot, and use dovecot sasl in postfix as well. Authentication with ntlm works well from Mac OS X Mail.app, as well as from Outlook Express, but fails with Outlook. Strangely enough, ntml authentication works in Outlook when using smtp (via postfix), but neither from imap or pop3 (both dovecot). As dovecot sasl handles all authentication against a mysql userdb, this strikes me as very strange. I've instructed my clients with Outlook to fetch mail using a ssl- encrypted connection, and to send using ntlm-authentication. This works, but I would like to have ntlm available as an option to all my clients, without forcing them to change mail-clients. I've turned on auth_verbose, auth_debug and auth_debug_passwords, and compared the passwordstring with the one calculated using dovecotpw, and they match. The only odd thing is that the username is returned from Outlook as an all-caps string, so user(a)domain.tld becomes USER(a)DOMAIN.TLD. I don't know if it matters, but I don't think so, as changing the user-login to an all-caps version doesn't solve the problem. Any hints will be most welcome. /Lars

[Dovecot] MacOS X and quota-plugin
by Lars Skovgaard 13 Nov '06

13 Nov '06

Hi all, I've installed dovecot 1.0 rc12 on a MacOS X client system with only a handful of users – all virtual – and would like to enable quotas. I've tried searching the wiki for information on how to do this, but haven't been able to find anything – which is why I turn to the list in hope there's someone out there who can point me in the right direction. I've compiled dovecot without any other authentication than sql and pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix when I get around to it). The installation went smoothly, and dovecot is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the log, slightly altered to protect user-identities: Nov 8 23:05:09 SD-Server dovecot: imap-login: Login: user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with signal 11 Nov 8 23:05:09 SD-Server crashdump[22663]: imap crashed Nov 8 23:05:09 SD-Server crashdump[22663]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:12 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:13 SD-Server dovecot: child 22665 (imap) killed with signal 11 Nov 8 23:05:13 SD-Server crashdump[22666]: imap crashed Nov 8 23:05:13 SD-Server crashdump[22666]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:16 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:17 SD-Server dovecot: child 22670 (imap) killed with signal 11 Nov 8 23:05:17 SD-Server crashdump[22671]: imap crashed Nov 8 23:05:17 SD-Server crashdump[22671]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log This is what I have done in dovecot.conf to enable quota: protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap } plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs } As you might guess from the lines under "plugin", I've tried a lot of different combinations. If I enable ANY of the above lines under plugin, the child-processes die upon login. When all have been commented out, there's no more crashing – until I try to see how much space is available, then it crashes again. I've tried adding an extra "quota" field to my mysql userdb to handle quotas, but with the same result. mysql-query looks like this (as described in the wiki): user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS quota FROM users WHERE userid = '%u' As with the settings in dovecot.conf, Ive tried various combinations of dict, dirsize and so on, but without any luck. This is what the entries in my crashdump file looks like: Host Name: SD-Server Date/Time: 2006-11-09 00:06:17.151 +0100 OS Version: 10.4.7 (Build 8J135) Report Version: 4 Command: imap Path: /usr/local/libexec/dovecot/imap Parent: dovecot [8370] Version: ???

Procmail writes to the folders, but it uses dotlocks, and I don't have logs of it crashing, whereas I do have logs of dovecot crashing :) I'm confused as to what the last sentence says, do you mean that you were able to reproduce the crash?

http://dovecot.org/releases/dovecot-1.0.rc11.tar.gz http://dovecot.org/releases/dovecot-1.0.rc11.tar.gz.sig Hopefully the last RC release? As far as I know there are no major problems left now. If nothing big shows up, v1.0 should be out in a couple of weeks. * Renamed default_mail_env to mail_location. default_mail_env still works for backwards compatibility. * deliver: When sending rejects, don't include Content-Type in the rejected mail's headers. * LDAP changes: * If auth binds are used, bind back to the default dn before doing a search. Otherwise it could fail if a user gave an invalid password. * Initial binding at connect is now done asynchronously. * Use pass_attrs even with auth_bind=yes since it may contain useful non-password fields. + passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP environments to the checkpassword binary so we're UCSPI (and vchkpw) compatible. - mbox handling was a bit broken in rc10 - Using Dovecot via inetd kept crashing dovecot master - deliver: Don't crash with -f "". Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

We use Dovecot on a cluster (10'000 domains, 30'000 account) without any problem with pop/imap. We use Dovecot 1.0 RC10 Now we use virtual transport from postfix for mail delivery. We need the Dovecot LDA for sieve support. We test this solution on some domains with success. But if we change the configuration of all our domains, we have a lots of bounce with this error in postfix log: postfix/pipe[24573]: 4F6D7CF11: to=<info(a)XXXX.com>, relay=dovecot, delay=1200, status=bounced (Command time limit exceeded: "/usr/local/dovecot/libexec/dovecot/deliver") If I watch the deliver activity with ps/awk/watch, I see that if deliver duration time exceed some seconds, the deliver process stay in memory but do nothing.

One example is enough to see what I am referring to. I am using Postfix for my mail-server. If I change the permissions on the directory to '1777' the error goes away and everything seems normal. The problem is that I should not have to do that and I do not understand what the problem is. Has anyone else experienced this phenomena and come up with a solution? Thanks! -- Gerard "Off list mail from *.gmail.com is rejected/deleted unseen. Don't waste your time."

[Dovecot] Using Substring Width with Mailhome Variables
by Matthew Fisch 12 Nov '06

12 Nov '06

Hello All, I am currently running Dovecot v1.0.rc13 from dovecot-1.0-0_31.rc13.fc5.at.i386.rpm on Linux HOST 2.6.17-1.2157_FC5 #1 Tue Jul 11 22:55:46 EDT 2006 i686 i686 i386 GNU/Linux. I am trying to install Dovecot in a large mail hosting environment and running into troubles. I have specified my mail home in dovecot.conf as follows: default_mail_env = maildir:/mnt/fileserver/maildir/%0.1d/%1.1d/%d/%n I've also tried among other variations: default_mail_env = maildir:/mnt/fileserver/maildir/%0d/%1.1d/%d/%n The expected behavior here, is to resolve this to: /mnt/fileserver/maildir/a/b/abc.com/user However, Dovecot seems to resolve this to: /mnt/raidzone01/maildir/abc.com/bc.com/abc.com/user/ It appears to me using 'width' with a substring does not work as is advertised on http://wiki.dovecot.org/Variables. This page does describe I need to be using 1.0-tests, what is 1.0-tests? I've also tried the default FC5 package: 1.0-0.beta8.2.fc5. Did I misunderstand the syntax? Am I using the wrong version? I won't be able to use dovecot without support for this feature as I am hosting many thousands of domains and know not how else to resolve them all.

[Dovecot] RFC 2822 - message-id
by Tom Allison 10 Nov '06

10 Nov '06

I was porting some email from one imap server location to another and ran into a feature of something. One of them writes message-id as 'Message-Id' and the other writes it as 'Message-ID'. Because of this, all the messages are forever different. All mail is delivered from postfix and will be in the future. But I'm asking which of these syntaxes is correct or if there is a right/wrong way of writing the headers? RFC2822 doesn't come right out and say it, but all the examples therein are "Message-ID". RFC 822 says they are all the same. Both?

[Dovecot] 1.0.rc12 released
by Timo Sirainen 10 Nov '06

10 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc12.tar.gz http://dovecot.org/releases/dovecot-1.0.rc12.tar.gz.sig Since rc11 has problems compiling with BSDs, here's a new release. Just two changes: - rc11 didn't compile with some compilers - default_mail_env fallbacking was broken with --exec-mail Here's also again the rc11 changes: * Renamed default_mail_env to mail_location. default_mail_env still works for backwards compatibility. * deliver: When sending rejects, don't include Content-Type in the rejected mail's headers. * LDAP changes: * If auth binds are used, bind back to the default dn before doing a search. Otherwise it could fail if a user gave an invalid password. * Initial binding at connect is now done asynchronously. * Use pass_attrs even with auth_bind=yes since it may contain useful non-password fields. + passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP environments to the checkpassword binary so we're UCSPI (and vchkpw) compatible. - mbox handling was a bit broken in rc10 - Using Dovecot via inetd kept crashing dovecot master - deliver: Don't crash with -f "". Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

[Dovecot] Qpopper migration?
by Steve Goodman (lists) 09 Nov '06

09 Nov '06

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is primarily POP3, with a small number of heavy IMAP users causing the system grief. There are a large number of POP3 users who leave messages on the server. What I want to ensure doesn't happen is that they are forced to download them again. Do I need to add anything specific in the pop3_uidl_format or am I barking up the wrong tree? Kind Regards, Steve

[Dovecot] SSL-read error in logfile
by Egbert Jan van den Bussche 08 Nov '06

Now most things seem to work (rc12 on Mandriva 2007.0), I've been looking more thoroughly at the syslog file. I see a 'syscall failed' at the end of a normal timed poll from the client.

[Dovecot] Quota without dovecot LDA
by Riccardo Bini 08 Nov '06

08 Nov '06

Hi all, I use dovecot with maildir quota plugin + qmail + vpopmail but not dovecot LDA. My dovecot configuration: default_mail_env=maildir:~/Maildir:INDEX=/var/cache/dovecot/indexes/%h/%u:CONTROL=/var/cache/dovecot/control/%h If CONTROL env is set the maildirsize file is stored in /var/cache/dovecot/control/ but I use vpopmail as LDA. It's possible to add a setting in dovecot.conf to specify if dovecot LDA is active?? This is my pseudo-patch: src/plugins/quota/quota-maildir.c static const char *maildirsize_get_path(struct mail_storage *storage) { if (lda_enable) { return t_strconcat(mail_storage_get_mailbox_control_dir(storage, ""), } else { bool is_file; return t_strconcat(mail_storage_get_mailbox_path(storage, "", &is_file), "/"MAILDIRSIZE_FILENAME, NULL); } } dovecot.conf: lda_enable = no Ciao Rick

[Dovecot] How to give system and virtual users their own mail_location?
by Egbert Jan 08 Nov '06

08 Nov '06

Hi all. Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject). I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it? Thanks for any hints! Egbert Jan (NL)

[Dovecot] L4 probes..
by Jorgen Lundman 08 Nov '06

08 Nov '06

Probably a special case here, but everytime the L4 probes the port, a line as added to the log. This gets a bit noisy. If a random IP connects, I'd want to see it, but maybe it would be nice to have the option to silence the log entry from certain hosts. For now I patch it locally, but without any .conf finesse. For example: Nov 8 10:55:24 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=172.16.253.5, lip=172.16.253.128, TLS handshake Nov 8 10:58:00 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Aborted login: rip=172.16.253.5, lip=172.16.253.128 -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] deliver feature request (filter)
by Neal Becker 08 Nov '06

08 Nov '06

I'm using maildrop for delivery, because I want to filter through spamassassin before delivery. Maildrop makes that trivial. It seems deliver can pipe (one way) to a command, but what is needed is to pipe: deliver -> spamd -> deliver which is what the maildrop xfilter does.

[Dovecot] RC10 errors
by Eric Rostetter 07 Nov '06

07 Nov '06

I just installed a limited test of RC10 last night. So far, all is great except for errors being logged for one user (out of about 150 users total). This one user has not yet complained or anything, but the log file has repeated entries of the following format for him (host and username changed to protect the guilty/innocent): Oct 24 06:13:02 mail dovecot: IMAP(username): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Oct 24 06:13:02 mail1 dovecot: child 18235 (imap) killed with signal 6 I find it most interesting that only 1 out of 150+ users is getting this error... And again, no complaints from the user. Setup is: wu-imap mbox files in /var/spool/mail (exported via NFS, but local to the dovecot server). Mail in ~/mail/ (NFS mount, foreign to devecot server). Indexes in /var/dovecot/indexes (local to dovecot server with no NFS at all). -- Eric Rostetter The Department of Physics The University of Texas at Austin Go Longhorns!

[Dovecot] rc13 soon
by Timo Sirainen 07 Nov '06

07 Nov '06

I think I'll just start making new releases whenever I've fixed something important. You'll have a while to report more bugs and then I'll make rc13 release, maybe in about 5 hours or maybe tomorrow. I updated already the nightly snapshot if you want to test the upcoming rc13. Changes so far: + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying

[Dovecot] rc12 dovecot-auth core dump with ldap

Hi, I've got a core dump during initialisation when I use 1.0.rc12 and LDAP with authenticated binds in Solaris. It worked OK in 1.0.rc10.

[Dovecot] suspected bug in dovecot-ldap setup?
by Pedro Venda 07 Nov '06

07 Nov '06

Hi everyone, [first post: long and boring. beware!] I've been working on a virtual multidomain MX server with pop3 access. Accounting for users/domains is done via OpenLDAP with the Jamm[1] schema and dovecot is 1.0rc10 (dovecot-1.0-0_27.rc10.el4.at fetched as RPM from atrpms.net for CentOS 4.4). I intended to have authenticated binds but there was a problem with the user_filter directive being ignored: user_filter = (&(objectClass=JammMailAccount)(mail=%n@%d)(accountActive=TRUE) (delete=FALSE)) dovecot: Oct 26 16:20:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=<hidden> dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): bind search: base=o=hosting,dc=example,dc=com scope=subtree filter= **(&(objectClass=posixAccount(uid=dave(a)info.test))** dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): unknown user dovecot: Oct 26 16:20:59 Info: auth(default): client out: FAIL 1 user=dave(a)info.test dovecot: Oct 26 16:20:59 Info: imap-login: Disconnected: user=<dave(a)info.test>, method=PLAIN, rip=::ffff:192.168.0.69, lip=::ffff:192.168.0.5, TLS (nevermind the data, it's test only) As you can see from the info file, the search filter used was being (&(objectClass=posixAccount(uid=dave(a)info.test)) and not (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)). I sorted this out by trying to enable auth_bind_userdn: auth_bind_userdn = mail=%n@%d,jvd=%d,o=hosting,dc=example,dc=com Now, the login worked well and the debug info is as follows: dovecot: Oct 27 12:01:48 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=AGRhdmVAaW5mb y50ZXN0AFRlbXAuMTIz dovecot: Oct 27 12:01:48 Info: auth(default): client out: OK 1 user=dave(a)info.test dovecot: Oct 27 12:01:48 Info: auth(default): master in: REQUEST 1 10634 1 dovecot: Oct 27 12:01:48 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=JammMailAccount)(mail=dave(a)info.test) (accountActive=TRUE)(delete=FALSE)) fields=mailbox dovecot: Oct 27 12:01:48 Info: auth(default): master out: USER 1 dave(a)info.test mail=info.test/dave/ uid=5000 gid=5000 (nevermind the debug data, passwords, etc. it's test only) In this case, the search filter is ok: (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)) So aparently, the auth_bind_userdn directive that supposedly adds a performance gain by sparing one bind request, seems to interfere with the user_filter directive. I suspect this might be a bug, so here's my report. Is this a new issue? Thanks for surviving this far through this post, Best regards, Pedro Venda.

[Dovecot] Store outgoing mail in users mailbox
by Mark Ruys 07 Nov '06

07 Nov '06

This might be a MTA question, but because I use Dovecot as an LDA, maybe some can help me here. Our users would like that outgoing mail is automatically saved in some folder, say Sent. We use Postfix with virtual domains, Maildir and Dovecot+Sieve as LDA. Outgoing mail is relayed by our imap-server (with authentification of course, no open relay). Most people seem to advice Postfix sender_bcc_maps and Dovecot's deliver with the -m argument. But I can't get it work.

It looks like "dovecot-archive:" should be a real email address, not a transport (this give an idea of my Postfix knowledge ;). Then I tried: In sender_bcc_map: tester(a)ruijs.cc tester+archive(a)ruijs.cc But I don't think Dovecot's LDA supports plus addressing. So my question is, has anyone here done a similar thing in a similar setting. If so, how did you configure it.

[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Ivo Truxa 06 Nov '06

06 Nov '06

I have the same problem after upgrading to RC10. Did you find a solution? Should I update to RC11 or rather downgrade back to an earlier version? Thanks, Ivo Truxa >>>>>>> original message >>>>>>> Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

[Dovecot] v1.0 plans, rc11 tomorrow
by Timo Sirainen 06 Nov '06

06 Nov '06

As you can probably guess from my today's burst of activity, I'm no longer extremely busy. Actually it looks like for the next 3-4 weeks I don't have anything especially time consuming to do. So it's time to get Dovecot v1.0 released :) I've now read all the mails from this list again, and it looks like pretty much the only problems with rc10 was the mbox assert crash, which is now fixed. My TODO contains: v1.0 blocker: - inetd logins are broken? I should look more into this.. I only remembered this just now while writing this mail. New non-v1.0 blockers: - trash plugin is apparently broken? - mbox_min_index_size != 0 causes Invalid new transaction log sequence (4 >= 4) The old preferrably-fixed-for-v1.0 items are: - ldap auth is leaking memory? maybe not, maybe it's something else. - master leaks log fds with kqueue. I don't have a machine to test this on. Could someone give me an account in some BSD system for a while to test this? Anyway, I'll most likely release rc11 tomorrow, but it would be nice if you tested today's CVS snapshot already to see if I accidentally broke something. :) http://dovecot.org/nightly/dovecot-latest.tar.gz Oh and one thing that I wanted for Dovecot v1.0 was nice documentation. I think the current wiki is a bit chaotic. I started http://wiki.dovecot.org/NewIndex a long time ago. Maybe I should finish it finally and put it as the new main index..

[Dovecot] Auto-expire messages in a folder
by Mike Cisar 05 Nov '06

05 Nov '06

I have a Fedora 5 server running Dovecot (currently 1.0 rc10). The spam filter (amavis) automatically tags email (using plussed addressing) such that messages flagged as spam are sorted into a "spambox" folder by procmail. Seemed like a good idea at the time, but because of some legacy issues with filesystem quota also being in place, combined with most users connecting with POP3 rather than IMAP... spam doesn't stay in their inbox, they don't check their spambox and they are very quickly over quota. What I would like to do is stick with the "spambox" folder idea, but have any messages in that folder which are older than a certain number of days deleted automatically. Could this be done by Dovecot? If so how would dovecot know to visit all the user's mailboxes to do it... or would it only be able to do so when a user logged in via IMAP (as opposed to POP3)? If not, is anyone aware of a script that I could run in nightly maintenance to do a cleanup pass on all the mailboxes? I know there are any number of ways that this could be accomplished but I would like to do it as much within my existing framework as possible... sendmail/procmail/amavis on the delivery side, dovecot in the middle, horde/imp for webmail and whatever email client the end users have (likely Outlook/Outlook Express for the most part)... all pretty generic, standard mailbox formats... nothing fancy like data stored in mySQL or anything like that. As everyone encounters, the more parts you change, the more other parts you have to fix to be compatible with the changes :-) Obviously I would like the solution to also be as feature rich as I can at the same time (might as well wish for it all right :-). Maybe for the sake of the POP3 folks it would also be nice to generate a once-daily email with the names, subjects of the messages in the folder saying "here's what is in your spam folder, please log in to webmail to manage your spam" (and in a perfect world some sort of link to click on which could move the message from the spambox back into the inbox). Does anyone have any solutions they can share that run within a similar framework to what I have set up? The thing that I need in the immediate term is to purge the spam folder automatically, the mid-term goal is to evolve that into a sort of spam-processing center/solution for the users. Thanks for any suggestions! Cheers, >>>>> Mike <<<<<

[Dovecot] ~/.maildir preferable to %h/Maildir and ~/Maildir?
by Jeff Kowalczyk 05 Nov '06

05 Nov '06

I have a recently deployed dovecot server and am readying another. Upon updating to rc12, I note the following change in the default dovecot.conf file: -default_mail_env = mbox:/var/spool/mail/%u:INDEX=/var/dovecot/%u +mail_location = maildir:~/.maildir Integrating this change to my local dovecot.conf: # formerly used default_mail_env = maildir:%h/Maildir # dovecot default mail_location = maildir:~/.maildir mail_location = maildir:~/Maildir With unix users of the form: myuser:x:505:100:My User:/home/myuser:/sbin/nologin each having ~/Maildir, should I: 1) use the ~/.maildir form over ~/Maildir. 2) use the ~ instead of %h 3) do anything for dovecot's benefit (reindex, etc.) besides a per-user 'mv ~/Maildir ~/.maildir' if 1). I came straight from an ancient sendmail mbox setup to dovecot, so I want to do things the best-pracitce IMAP/dovecot way. Thanks.

[Dovecot] Sending email using IMAP
by Marc Perkel 05 Nov '06

05 Nov '06

This is something for after the 1.0 release but I think it's important and I'm going to try to figure out how to make it happen. I'd like to see some way to pass outgoing email from Thunderbird back to dovecot through some new command that we would have to make up. Email would be sent back over the IMAP connection and when Dovecot gets it dovecot would hand it off to an SMTP server that would deliver it. If a crude experimental spec can be written I'll try to find someone on the Thunderbird side to write some sort of module to talk to it. The reason for this is that I think that the elimination of SMTP from the client is a big step to control spam. The idea being that if IMAP can transfer outgoing mail the SMTP wouldn't be necessary for clients and we can block port 25 on windows machines and viruses can't send email. And the virus wouldn't have access to the IMAP password so viruses can't authenticate to send mail. So - the key question is - what would it take to create an outgoing spec for sending email over IMAP? Like to see something clean and simple.

[Dovecot] MySQL Configuration
by Gerard Seibert 04 Nov '06

04 Nov '06

Dovecot 1.0.rc10 FreeBSD 6.1 This is probably a dumb question; however, I have never let a little thing like that bother me in the past. In the 'dovecot.conf' file there are the follow two sections: # SQL database passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } I keep the 'users' and their respective 'passwords' in the same MySQL database. I am not sure why I wouldn't. Therefore, would it not make more sense to have just one MySQL configuration line in the 'dovecot.conf' file rather than two, or am I missing something here? -- Gerard Seibert gerard(a)seibercom.net Laws are like sausages.

[Dovecot] auth-req-handler.c adds spurious tab
by Chris Laif 04 Nov '06

04 Nov '06

If the auth backend (postgresql in my case) returns extra fields, and all of these extra_fields begin with 'userdb_', the auth_callback functions adds an unwanted extra tab at the end of the response: auth(default): client out: OK^I8^Iuser=foo@bar^I This extra tab at the end confuses exim's dovecot-auth handler (the exim-dovecot auth handler does not correctly count the number of returned fields then (side note: the code on exim's side should probably be cleaned up as well)). A quick fix is attached below.

I made a copy of the mbox file, and find that it's over a megabyte long. Checking the postfix maillog I find that only three messages arrived for that user in the hour preceding the start of this behavior (all SPAM). No other users are affected, and I can't see anything obviously wrong in the mbox file. Could a bad message cause this?

[Dovecot] Server-side mail archiving - possible dovecot lda feature?
by Charles Marcus 03 Nov '06

03 Nov '06

Hi Timo, I have a question on the feasibility of adding the capability directly in dovecot LDA (or maybe this wouldn't be the correct place?) to provide a server-side mail archiving feature. What I'd like is a simple way to define a maildir, ie: vmail/archive/$user/Inbox and vmail/archive/$user/Inbox.Sent And then have the dovecot LDA deliver a copy of all mail (incoming and outgoing) to this archive folder. Is the dovecot LDA the best place for this to go? Or would an entirely new plug-in be more appropriate? My boss may be willing to pay to have this capability added. I have investigated other third party solutions, but I would prefer something that is tightly integrated with dovecot. I look forward to your response... -- Best regards, Charles

[Dovecot] any idea why the mail downloading is slow?
by LeVA 03 Nov '06

03 Nov '06

Hi! I'm using rc10, but had this problem with previous releases too. Not sure if this is a dovecot problem, but I can not think of anything else. The mail downloading with pop3 is ~very slow, approx. 20 Kbyte / sec. no matter how many mails I've got in my mailbox, or how big are the mails. My ISP provides me a dedicated 100mbit line, and everything else works as fast as expected eg. http, ftp, scp... The OS is OpenBSD 3.9-stable and the system is not under heavy load at all. I've tried to turn off TLS but there was no change. Is the pop3 protocol this slow by design or there is something wrong with my setup? Thanks! Daniel -- LeVA

[Dovecot] CRAM-MD5 auth broken with postgresql passdb?
by Chris Laif 03 Nov '06

03 Nov '06

I'm currently experiencing a problem which has already been described by Jonathan in http://www.dovecot.org/list/dovecot/2006-August/015501.html If I use CRAM-MD5 auth with passwd-file as a backend (Thunderbird client) everything works fine (MD5-hashes have been shortened for readability): dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: f12c884ba3cc82.. dovecot: imap-login: Login: user=<bob(a)foo.bar>, method=CRAM-MD5, rip=10.0.0.123, lip=10.0.0.234 My passwd file contains a line like this: bob@foo.bar:{HMAC-MD5}f12c884ba3cc82.. If I change to postgresql-based passdb, PLAIN auth works (!) and CRAM-MD5 does not work: dovecot: auth(default): sql(bob(a)foo.bar,10.0.0.123): query: SELECT 'bob(a)foo.bar' AS user, '{HMAC-MD5}f12c884ba3cc82..' AS password dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: dovecot: auth(default): cram-md5(bob(a)foo.bar,10.0.0.123): password mismatch Please note the ultra-simple SELECT-statement (I've tried other combinations as well - no success). sql.conf setting is "default_pass_scheme = HMAC-MD5". Dovecot version 1.0.rc10. In the postgresql-based example the "Credentials:" variable is empty. I wonder if this is a bug in dovecot. Please let me know if you need any further information to resolve this issue. Thanks, Chris (As a side not I still do not understand how CRAM-MD5 auth is able to work without a plain text password, but that's another story. If it works with an HMAC-MD5 hash in a passwd-file backend it should work with the postgresql-db backend as well.)

Hello, I found this thread: http://www.dovecot.org/list/dovecot/2006- September/015955.html and have successfully compiled and installed cmusieve plugin. How does one test to make sure its being loaded? It's not parsing my sieve files in the users homes and I'd like to first check if the plugin is being loaded, since I am getting no errors about it. Thanks

[Dovecot] Postfix + Dovecot LDA Problem
by Steven F Siirila 03 Nov '06

03 Nov '06

I am having a problem setting up a server to handle e-mail in a way in which it had always done traditionally, but with Postfix+Dovecot LDA. Here's a rundown... Solaris 9 Postfix 2.3.3 Dovecot 1.0.rc10 Postfix non-defaults (postconf -n): alias_maps = dbm:/etc/mail/aliases command_directory = /opt/postfix/sbin config_directory = /etc/opt/postfix daemon_directory = /opt/postfix/libexec debug_peer_level = 2 html_directory = no inet_interfaces = $myhostname mail_owner = postfix mailbox_command = /opt/dovecot/libexec/dovecot/deliver -f "$SENDER" mailq_path = /opt/postfix/bin/mailq manpage_directory = /opt/postfix/man masquerade_domains = tc.umn.edu masquerade_exceptions = root mydestination = $myhostname mynetworks = 127.0.0.0/8, ... (omitted) myorigin = $mydomain newaliases_path = /opt/postfix/bin/newaliases queue_directory = /var/spool/postfix readme_directory = no relayhost = [omitted.tc.umn.edu] sample_directory = /etc/opt/postfix sendmail_path = /opt/postfix/sbin/sendmail setgid_group = postdrop smtpd_client_restrictions = permit_mynetworks, reject unknown_local_recipient_reject_code = 550 This works just like our old MTA, with one exception: sending e-mail to addresses within our domain (@tc.umn.edu) requires us to specify the @tc.umn.edu -- otherwise it is rejected with a message like alias(a)host.tc.umn.edu does not exist. I want such messages to be relayed to the relayhost. When I set mydestination to null, and luser_relay = $user@$domain the message goes into a black hole (I never get the message, nor do I get an NDN.) I am posting this to both the Dovecot and Postfix lists since I'm not sure where the fault lies, configuration- or software-wise. Thanks in advance for any helpful tips. -- Steven F.

[Dovecot] compiling dovecot-sieve

Our server is an CentOS4.4 box and we use the atrpms built RPMs for installing dovecot. I am wanting to use the sieve plug-in so I've followed the dovecot wiki instructions, downloaded the files from CVS, but I'm not sure what configure options to use. When I try without any options I get: dovecot-config not found from /usr/src/dovecot-sieve, use --with-dovecot=PATH to give path to compiled Dovecot sources I tried using "./configure --with-dovecot=/usr/libexec/dovecot" but get the same problem.

[Dovecot] making dovecot and exim write to one log
by Zbigniew Szalbot 02 Nov '06

02 Nov '06

Hello, I am looking for some advice. I am trying to force dovecot to run to the same log as exim does. In dovecot.conf I put the exim log path /var/log/exim/mainlog. I restarted dovecot and the process worked fine. However at midnight exim log file is rotated and since then dovecot stops logging to this log. In syslog.conf I put: mail.* /var/log/exim/mainlog And in newsyslog.conf I have: /var/log/exim/mainlog mailnull:mail 640 60 * @T00 Z I used to have an N flag next to Z but after reading the man I realized that its job is not to inform other processes about log creation. My qeustion is how do I set up things that dovecot and exim happily write to one log without having to restart dovecot at midnight? I am fairly new to FreeBSD which I use so I beg your patience with me. Thanks! -- Zbigniew Szalbot

Re: [Dovecot] deliver + quota failure
by Mark Ruijs 02 Nov '06

02 Nov '06

I investigated the deliver with quota's bug a little more (rc10, mysql, virtual domains, maildir). My log files reads: deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Info: sieve runtime error: Keep: Generic Error deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Error: open(ruijs.cc/test//.temp.in2sports2.vianetworks.nl.13210.72d247ac698d0019) failed: No such file or directory deliver(mark(a)ruijs.cc): Info: msgid=<dovecot-1162066721-407295-0(a)in2sports2.vianetworks.nl>: saved mail to Junk Dovecot tries to deliver, but notices quota exceeded. I don't think Sieve is playing a role here - I added Sieve before I encountered the problem. Two problems: 1) The .dovecot.lda-dupes can't be written (that's what the open...failed notice is about). 2) The Quota Exceed mail seem to contain mal-formed headers (that's why it the notice-mail ends in my junk-folder). Digging into deliver.c, I noticed that auth_client_put_user_env() changes the HOME environment from /var/mail (which is ok), to ruijs.cc/test/ (which is the maildir, relative to /var/mail). And then fopen fails (see the trace below). So I think that the code auth_socket = getenv("AUTH_SOCKET_PATH"); if (auth_socket == NULL) auth_socket = DEFAULT_AUTH_SOCKET_PATH; ret = auth_client_put_user_env(ioloop, auth_socket, destination, process_euid); if (ret != 0) return ret; home = getenv("HOME"); if (home != NULL) { /* If possible chdir to home directory so core file could be written. If it fails, don't worry. */ (void)chdir(home); is the key. Should the chdir be done *before* the call to auth_client_put_user_env()? I'm not familiar with the internal workings of the Dovecot LDA, so I won't suggest a proper fix. Who will. As for the mal-formed headers, I'll take a look at it later.

[Dovecot] INBOX un-subscribable (is that a word?)
by Jim Horner 02 Nov '06

02 Nov '06

I am trying to get open-xchange installed and working (which after two days might be futile). In doing this I noticed that no email client can subscribe to INBOX. I'm using rc10 and my namespaces are the following. 99% of the email clients ignore the inability to subscribe to INBOX and display all the folders underneath anyway which is why I've never noticed this issue... however, open-xchange is not in that camp and only displays messages in INBOX. All folders are in the subscriptions file including INBOX but all email clients always list INBOX as not subscribed to. COMPANY are ROOTMAIL are share folders with ACLs in /etc/dovecot/acl and those top folders are not subscribable either. namespace public { separator = . prefix = COMPANY. location = maildir:/home/services/mail/arinbe.com/arinbe/Maildir:CONTROL=%h/shared-set… hidden = no inbox = no } namespace public { separator = . prefix = ROOTMAIL. location = maildir:/home/services/mail/arinbe.com/rootmail/Maildir:CONTROL=%h/shared-s… hidden = no inbox = no } # default namespace namespace private { separator = . inbox = yes hidden = no prefix = INBOX. }

Hello all, I recently switched to dovecot on my FC4 server from UW-IMAP on my Mac OS X 10.3 machine and I was able to get my inbox and my trash box to be seen without any issues but all of my other mailboxes don't seem to show up. My mail directory is ~/mail and that is where I placed all of my mailboxes that I moved from my mac, but when I log into my new server using SSL/IMAP, only my trash and my inbox show up. My other mailboxes don't show up at all. Can anyone tell me how I can get my other mailboxes to show? As far as I know these mailboxes are standard unix mailbox files. Thanks

On our solaris systems we quite often sees dovecot coredump on exit when trying to free a null buffer. After including if (array->buffer == NULL) return; in array_free() in array.h these coredums have been avoided. hmk

[Dovecot] BUG in RC10 deliver using mbox format
by Steven F Siirila 02 Nov '06

02 Nov '06

After recently adding the -f parameter to the call to the deliver command which is called by Postfix, I found that e-mail with a null return path (MAIL FROM:<>) was causing Dovecot deliver to SEGFAULT. I verified this by making this patch to deliver.c (notice I fixed a typo here, too): *** deliver.c.orig Fri Oct 13 07:32:28 2006 --- deliver.c Fri Oct 27 21:26:08 2006 *************** *** 446,454 **** i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envleope argument"); } ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, --- 446,455 ---- i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envelope argument"); } ! if (*argv[i]) ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, While this fixed my SEGFAULT, it still leaves the "From_" line with the default "dovecot.deliver" as the return path, something I don't want. It should be "MAILER-DAEMON" or some-such just like all the other LDAs in the case of a NULL return path. Perhaps there needs to be a new parameter so one can specify what a NULL return path should be converted to when it is encountered... Also, note that the "Usage" message in deliver.c does not include the relatively new -f option either, so that should have been part of my above patch as well. -- Steven F.

[Dovecot] quota with sendmail and dovecot
by Antonio Casado Rodríguez 02 Nov '06

02 Nov '06

I have a problem with dovecot and quotas I don't want quota in INBOX with sendmail (mbox), it's work ok. Sendmail can put the new messages in INBOX although exceed the quota limit. I have two namespace in dovecot: namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/Public/Maildir/%n_mbox_indexes:INBOX=/var/mail/%n } namespace private { separator = / prefix = "" location = maildir:/Public/Maildir/%n } I have this quota: plugin { quota = maildir:storage=10240 } It's work ok, i have 10 MB in INBOX and i have 10 MB in maildir. My clients are Mozilla Thunderbird My problem: when Sendmail put one new message in INBOX, Thunderbird see it, but the quota don't change. I think that when dovecot do a full sync it must update the quota.

[Dovecot] mbox_sync_read_and_move failure
by Timothy Daly 02 Nov '06

02 Nov '06

Hi, I recently switched to using dovecot for my IMAP server. I'm running dovecot 1.0rc10 on redhat linux 7.3. The filesystem is ext2, not NFS. I'm using mbox for mail storage. It worked okay for a day or two, but now when I try to check my mail I get an error from evolution, my imap client, saying that the server unexpectedly disconnected. In the server logs I see: Nov 2 13:10:49 tenkan dovecot: imap-login: Login: user=<tim>, method=PLAIN, rip=192.132.92.15, lip=216.114.78.229, TLS Nov 2 13:10:58 tenkan dovecot: IMAP(tim): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Nov 2 13:10:58 tenkan dovecot: child 30315 (imap) killed with signal 6 I see that this came up on this list a little while ago, but it doesn't sound like it got resolved. For the moment, I'm unable to read my mail via IMAP. :/ Any ideas?

[Dovecot] Dovecot-auth stand alone
by Jorgen Lundman 02 Nov '06

02 Nov '06

Since you have to have a SASL implementation with Postfix, either Cyrus or Dovecot, would it be feasable to have autoconf options to build only those parts required? Currently I attempt to disable most things, except for LDAP which we want to use: ./configure --with-ldap --without-pop3d --without-passwd --without-passwd-file --without-shadow --without-pam --without-checkpassword --without-bsdauth --without-vpopmail --without-ssl --without-deliver --without-sql-drivers --with-storages= That still compiles, and installs, imap. No way to stop that. However, master process "dovecot" does not want to start with "protocols=" set to empty. This is somewhat understandable, but I really do not want any listening ports, just the Unix auth socket and dovecot-auth process. Bind localhost for now? I take it I should run dovecot-auth as stand-alone, setting the AUTH_1 environment variable as well as a few others.

[Dovecot] 1.0.rc10 status report
by David Lee 02 Nov '06

02 Nov '06

(Background: Relatively new to dovecot; looking to do transparent replacement of long-established UW-IMAP on cluster of Linux boxes which NFS-mount a shared "/var/spool/mail".) With rc8, where I had already increased "login_max_processes_count" from default 128 to 1024, we had still hit the issue of too many logins crashing dovecot, so that trial had only lasted a couple of hours. With rc10, I doubled this to try to avoid the problem (I didn't want to risk testing the new code that addressed the problem... sorry!). We ran for almost a full working day. Good! Because of a few issues (below) I then backed off. 1. "User unknown": We use NIS for our passwd information. On the earlier rc8 test we had had several occurences of "User unknown" (from "deliver") giving "dsn=5..." for perfectly valid users. So for this rc10 test I applied a local patch so these were reduced to "EX_TEMPFAIL" (dsn=4...). (This was triggered, as epected, a few times and subsequent delivery attemtps succeeded.) I strongly suspect that this is some sort of issue with FC5, probably "nscd" and nothing to do with dovecot. Hints would be nice, but from the dovecot perspective you may probably ignore this item. 2. For one particular user, the "deliver" consistently gave: Failed to create storage for '...' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB:INBOX=... I think this is ultimately due to something strange in the user ".forward" file. I'd be delighted to follow this up with anyone else who might have seen it. Although in one sense we may be drifting off-topic, in another sense I suspect that there is scope for adjusting "deliver" to handle this more gracefully. 3. There were several occurences of: IMAP(...): file ../../../../../src/lib-storage/index/mbox/mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) child 30842 (imap) killed with signal 6 This looks particularly awkward. Any thoughts? 4. There were two occurences of: IMAP(...): file ../../../src/lib-index/mail-index.c: line 1801 (mail_index_move_to_memory): assertion failed: (index->fd == -1) child 20493 (imap) killed with signal 6 Again, this looks particularly awkward. Any thoughts? For these last two items, note that the indexes are currently NFS-shared alongside the INBOX area. I'm still not clear on how to regard the concept of indexes, as applied to a small cluster of machines, and handling simultaneous updates to INBOXes (analogous to the vital importance of INBOX locking for such updates). If one imagines the IMAP daemon (and pop and deliver) as file-clients of the (NFS-shared) INBOXes on a fileserver, do the indexes belong very close to the INBOXes (fileserver) or the dovecot software (file client)? So should I have the indexes on the fileserver (one instance), or should they be on each cluster machine's private storage (possibly several instances; one per cluster machine)? I've got them on the server; would they be better on the cluster clients? (Might that be the cause and fix of these two problems?) -- : David Lee I.T.

[Dovecot] valid_chroot_dirs question
by Luca Corti 02 Nov '06

02 Nov '06

Hello, I've got a dovecot setup using PAM and real system users. In this setup I also use pure-ftpd to give local users ftp access to their $HOMEs. To have pure-ftpd chroot into the user home i replaced /home/user with /home/user/./ in /etc/passwd. Unfortunately this breaks Dovecot this way: Oct 23 18:18:20 localhost dovecot: Invalid chroot directory '/home/foo' (user foo) (see valid_chroot_dirs in config file) and dovecot.conf says # ':' separated list of directories under which chrooting is allowed for mail # processes (ie. /var/mail will allow chrooting to /var/mail/foo/bar too). # This setting doesn't affect login_chroot or auth_chroot variables. # WARNING: Never add directories here which local users can modify, that # may lead to root exploit. Usually this should be done only if you don't # allow shell access for users. See doc/configuration.txt for more information. #valid_chroot_dirs = Now if I set valid_chroot_dirs = /home everything works, but the WARNING pretty much scares me since user foo HAS shell access. Is this safe? Is there a way to avoid this? Why I can't chroot to /home/foo/./ if I can to /home/foo ? I'm on 1.0rc10 thanks

[Dovecot] Installation of Dovecot
by Steven F Siirila 02 Nov '06

When I configure Dovecot to conform to our directory hierarchy, it insists on adding 'dovecot/' to the prefixes I specify. Is there any way to inhibit this? My configure command is: ./configure --prefix=/opt/dovecot --sysconfdir=/etc/opt/dovecot \ --libexecdir=/opt/dovecot/libexec --localstatedir=/var/opt/dovecot \ --without-sql-drivers --with-ssl=openssl \ --with-ssldir=/etc/opt/dovecot My problem is with the resulting directories: /opt/dovecot/libexec/dovecot is used instead of /opt/dovecot/libexec /var/opt/dovecot/lib/dovecot is used instead of /var/opt/dovecot/lib /var/opt/dovecot/run/dovecot is used instead of /var/opt/dovecot/run It seems that Dovecot assumes that libexecdir and localstatedir refer to non-Dovecot-specific directories, and adds 'dovecot/' to the path. Is there any way to avoid this?

[Dovecot] imap process crashing with "file mail-cache-fields.c: line 26: unreached"
by JB Zimmerman 02 Nov '06

02 Nov '06

Hoping someone's seen this and/or can help...heh. I'm running the at rpm of dovecot, version dovecot-1.0-0_27.rc10.el4.at. I'm running it on RHEL4, up to date. We're using Maildir (we're upgraded from a Courier-IMAP installation) and things are working...but...we have a few users with very large mailboxes (not their inboxes) where they archive stuff (200k+ messages). When they try to read those mailboxes, the imap server instantly drops the connection, and I get the following in the log: --cut-- Oct 27 11:20:11 hostname dovecot: IMAP(user): file mail-cache-fields.c: line 26: unreached Oct 27 11:20:11 hostname dovecot: child 27514 (imap) killed with signal 6 --cut-- host and user names changed to protect the guilty. I have tried increasing the imap process size max to 512, as well as doubling the IMAP command size to 131072 (bytes)? Neither made a difference. *other* mailboxes on the same account work fine. The error happens *immediately*, not after a timeout, as soon as they select the mailbox in their client (we're using Evolution, and have tried pine as well...I'm working on trying other clients). The Maildir caching optimization settings in the conf are left to default. Any ideas? Many thanks. J.B. Zimmerman --

The reply will then take the highest > priority in the queue. Is your primary goal with this replication to add redundancy or to distribute load such as for shared mailboxes? I've thought about the redundancy side of this a lot, but not so much about load distribution. It sounds like you're going for load distribution, but... If the goal is redundancy, I'd suggest that mailbox state is less important than the mail data. Index files can be recreated from the data, and would not even be needed on the secondary server(s) unless the primary fails. So I'd put a higher priority on getting the mail content to the secondary servers. If the goal is to distribute load for shared mailboxes, then your prioritization makes sense. Also, if the goal is redundancy, this design can be simplified a lot by having one master and one or more slaves. All modify operations would go to the master, so that you do not need global locks. Different sets of users would belong to different namespaces, so that you can have multiple replication paths in your cluster. You'd also want an API for the replication process so that third-party applications that modify mailboxes can log those changes so that they are replicated. And in that case, the replication process could be made generic enough so that it can be used to replicate any set of files, with or without Dovecot. Bill

[Dovecot] CRASH: mail-cache-fields.c crash - new info, hacked 'solution'
by JB Zimmerman 01 Nov '06

01 Nov '06

I'm baaaaack. :-) I've managed to implement a suggestion from Hans Morten Kind from this list that seems to have stopped the crashing. However, my hack - commenting out a call to i_unreached() - makes me queasy because I have no idea of the ramifications of it (I don't habitually code, myself). So I wanted to lay it out for y'all in case this is a problem that you feel should be looked at. So, here's my situation. Using dovecot-1.0.rc10 downloaded from dovecot.org. Built an RPM locally on my machine (as opposed to prior attempts, which used the AT rpms), which is running RHEL 4AS with all updates. Did *not* configure in postgres, mysql, sqlite, ldap-auth. Other than that, stock (openssl included, eg) - some file locations taken from AT RPMs' spec (redhat specific file locs). No patches performed. SPEC available if y'all think it'd help; the RPM built with no complaints, installed same. Using Maildir format, upgraded from a Courier install, so .folder.subfolder structure. Error behavior: When a user attempted to open a folder containing large numbers of messages (roughly 100k+ messages, as far as we can tell) they immediately got an error saying the server has disconnected. On the server side, I got this in the log (hostname 'magneto' obviously) ---cut--- Nov 1 15:18:16 magneto dovecot: IMAP(joeuser): file mail-cache-fields.c: line 26: unreached Nov 1 15:18:16 magneto dovecot: child 17599 (imap) killed with signal 6 ---cut--- Now, the folder in question is a folder of CVS commit messages (hence the size). If I go into the folder ("/home/joeuser/Maildir/.GNOME CVS commits/") and do 'rm -f dovecot-*' and then have the user try again, then they can open the folder and get a message list. dovecot will rebuild the various index files. However, as soon as they click on an individual message, bam, the same error behavior - and from then on, they can't get into the folder again unless we remove their dovecot files again. We tried this using Evolution, mutt and pine as the clients. All exhibited identical behavior. This is coming over TLS. NOW THE FIX: I made a change to the source (gasp!) that honestly I have no idea the ramifications of, but it has...well, not *fixed*, but sorta fixed it. As per Hans Morten Kind, I commented out the i_unreached() call in field_has_fixed_size(). After this, the mail is readable as is the folder list, but now there is an error message in the log. First things first, here's the change I made to dovecot-1.0.rc10/src/lib-index/mail-cache-fields.c: ---cut--- @@ -23,7 +23,7 @@ return FALSE; } - i_unreached(); +/* i_unreached(); */ return FALSE; } ---cut--- ...and here's what now happens in the log, to the same mail folder as above: ---cut--- Nov 1 15:59:42 magneto dovecot: IMAP(joeuser): Corrupted index cache file /home/joeuser/Maildir/.GNOME CVS commits/dovecot.index.cache: field header names corrupted ---cut--- At that point, I deleted the cache files again, and the error goes away. I also notice that the index.cache file in that folder is much, much larger than it was, from which I posit that the above error was because the crashing imap process had left an incomplete index file. Removing it thus forced a rebuild with the new code which seems to have fixed the problem. Thank you all for your patience. I hand this willingly over to the list. jb -- ------------------------------------ J.B.

[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Dominic Lepiane 01 Nov '06

01 Nov '06

Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

[Dovecot] moving public folders to private Trash
by Mark Nienberg 01 Nov '06

01 Nov '06

Using Thunderbird 1.5.0.4 against dovecot beta9: If a user has Thunderbird configured to move deleted messages into a Trash folder, then the user cannot delete folders in a public namespace. There is no problem deleting messages. Thunderbird says: "The current command did not succeed. The mail server responded: Can't rename mailbox to another storage type." All mailboxes (public and private) are maildir format. Users can successfully delete folders from their own private areas, and the folders then appear as subfolders of the Trash folder. Also, users can reconfigure Thunderbird to delete messages immediately instead of moving them to trash and then successfully remove public folders. Also, users can move public folders within the public namespace. So I think the problem boils down to the inability to move a folder from a public namespace to a private one, which is what happens when Thunderbird is configured to move deleted messages to a Trash folder.

[Dovecot] IMAP Dovecot with ISPConfig and shared folders?

Fedora 5, postfix, dovecot, ISPConfig server all running well, (don't want to break it) LOL. But, I do not have IMAP shared folders. These instructions on dovecot tell of how to setup namespace to be able to get shared folders. http://wiki.dovecot.org/SharedFolders But given everything is relative in ISPConfig, not sure if this is possible or if I could really mess things up. What tells dovecot to look in the various different web# folders for email? Am I better off using Symlinking???

[Dovecot] Problem report
by leslie.polzer＠gmx.net 31 Oct '06

31 Oct '06

Hello guys, Dovecot is a great IMAP server, I really like it :) I recently found an annoying problem, however: To sync my mail, I use OfflineIMAP, which usually works very smoothly. A spam mail with the year set to 2038 produced the error message "Invalid internal date" when OfflineIMAP tried to upload it to the server. Only deleting the messag helped. The usual data: Dovecot 0.99.14-1sarge0 on Debian Sarge x86. It would be nice to remove this date-smartness (?)... Kind regards, Leslie -- gpg --keyserver pgp.mit.edu --recv-keys DD4EBF83 http://nic-nac-project.de/~skypher/

[Dovecot] Continuing problems with zombied dovecot-auth procs; mail-cache-fields.c IMAP procs crashing
by JB Zimmerman 31 Oct '06

31 Oct '06

Folks- Hans Morten Kind was kind enough to confirm the issue I'm having with large mailboxes and the mail-cache-fields.c file (line 26: unreached error in logs when the imap process crashes out on large Maildirs). Has anyone implemented a fix for this that is both tested and applicable without making manual code changes myself, since I don't trust myself slashing about in source files? Ideally, has this problem been noted for fixing in a newer version? Failing that, if I downgrade to the 0.99 version shipped with RHEL4, has anyone found that to be more reliable? I used the 1.0rc10 in order to gain access to the 'namespace' conf directives so that upgrading from our current Courier Maildir installations would be as seamless as possible, but at the moment, I'm looking at having to roll back to Courier in order to fix this (and the next) problem. Also, we have found that using 1.0rc10 on RHEL4, using pam-ldap for account info and pam-krb for auth, has resulted in the eventual inaccessability of mail due to many zombied and unresponsive dovecot-auth processes. Restarting dovecot the first few times it becomes unresponsive will fix the problem, presumably by instantiating new auth procs, but eventually this no longer works since the restart doesn't actually kill off the zombied auth procs and the socket stops responding. Has anyone run into this problem? Thanks, J.B. Zimmerman RHEL4AS, fully updated, using the AT rpms: dovecot-1.0-0_27.rc10.el4.at --

[Dovecot] Multiple certificates
by Phill Edwards 31 Oct '06

31 Oct '06

I have dovecot version 1.0 relese 0.beta8.2.fc5 installed on my FC5 linux box. It acts as an IMAP server to my home LAN. I connect to it from the home PCs over SSL and have installed a certificate in the domain imap.edwards.home to enable this. However, I also use a web site called www.xs2mail.com which retrieves the email from my IMAP server (which has a public DNS entry called XXX.homelinux.com) and displays them in a web interface. I used to run uw-imap and this all worked fine. But since I went to Dovecot I can't use that site any more because it gives me this message: Login failure: Certificate failure for XXX.homelinux.com: self signed certificate: /C=AU/ST=NSW/L=Sydney/O=Edwards/OU=IMAP server/CN=imap.edwards.home/emailAddress=philledwards(a)gmail.com I assume it's getting upset because the certificate is for imap.edwards.home but the domain it's connecting to is XXX.homelinux.com. Is there a way to resolve this? I read something about using virtual servers but all I could find is this in a post somewhere - I don't know which file it goes, where in that file etc: <snip> 1.0-tests support "virtual servers", where this is possible: server foo { listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer } server bar { listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer } </snip> Can anyone help me figure this out? (PS - I can't just set up my own IMAP web interface because I can't run anything on port 80 with my ISP and I can't get out of our company firewall on anything other than port 80). Thanks in advance, Phill

[Dovecot] dovecot auth + postifx: how to disable PLAIN and LOGIN without TLS?
by Lev Serebryakov 29 Oct '06

29 Oct '06

Hello dovecot, I want to have all authorization in one place and don't use Cyrus-SASL. I cobfigure postfix 2.3.3 to use dovecot-SASL. I have next lines in main.cf: smtpd_sasl_security_options = noplaintext,noanonymous smtpd_sasl_tls_security_options = noanonymous But PLAIN and LOGIN are advertised by postfix :( Is it bug of postfix or dovecot-auth? I don't want to disable these mechanisms in auth {} stanza of dovecot.conf, because they are Ok over SSL/TLS. It works for dovecot-pop3 and dovecot-imap, but not for postfix :( postfix 2.3.3, dovecot 1.0rc10. -- Best regards, Lev mailto:lev@serebryakov.spb.ru

[Dovecot] LSUB and namespaces - how to get rid of multible prefixes
by Henrik Ostergaard Madsen 28 Oct '06

28 Oct '06

I'm using dovecot 1.0.rc7 and Squirrelmain 1.4.8 using IMAP on a Debian 3.1 Testing system, and I'm having a problem. When Squirrelmail (or other IMAP clients) submits an LSUB "" "*%", dovecot responds with: Request: A004 LSUB "" "*%" Response: * LSUB () "/" "INBOX.Sent" * LSUB () "/" "INBOX.Trash" * LSUB () "/" "INBOX.Drafts" * LSUB () "/" "mail/Sent" * LSUB () "/" "mail/Trash" * LSUB () "/" "mail/Drafts" * LSUB () "/" ".mail/Sent" * LSUB () "/" ".mail/Trash" * LSUB () "/" ".mail/Drafts" * LSUB () "/" "Sent" * LSUB () "/" "Trash" * LSUB () "/" "Drafts" * LSUB () "/" "INBOXSent" * LSUB () "/" "INBOXTrash" * LSUB () "/" "INBOXDrafts" * LSUB () "/" "./INBOX.Sent" * LSUB () "/" "./INBOX.Trash" * LSUB () "/" "./INBOX.Drafts" * LSUB () "/" "Test" Lsub completed. This is in spite of that only INBOX.Sent, INBOX.Trash, INBOX.Drafts and Test actually exists. I have tried with no explicit namespaces, only one with no prefix or with prefix "/", and with that again and all the above prefixes marked as hidden, but with absolutely no change in the LSUB repons. Due to this, Squirrelmail shows up a whole bunch of folders, but only the correct ones (without prefixes) works.. This has been the same with a few prior versions of dovecot 1.0 , but not with dovecot 0.99. It is the same for Squirrelmail 1.4.7, but I do not think the client matters.. Is there a setting or way to deal with this - or is it a bug? Regards, Henrik

[Dovecot] "dovecot dead but subsys locked" problem
by Carla Tironi Farinati 27 Oct '06

27 Oct '06

Hi, Following the advice of someone really helpfull here, I just installed Postfix/Dovecot (from rpms). I'm running CentOs 4.4. I followed this guide: http://www.howtoforge.com/linux_postfix_virtual_hosting I've got two problems, a)my server is now listed as RCB, whatever that means, I suppose that's close to spamming. "0: Connection refused. Your IP address is blocked(Spamhaus XBL) - see http://www.spamhaus.org/query/bl?ip=216.32.68.90 " b)[root@server ssl]# /etc/init.d/dovecot restart Stopping Dovecot Imap: [FAILED] Starting Dovecot Imap: [ OK ] [root@server ssl]# /etc/init.d/dovecot status dovecot dead but subsys locked I deleted the sybsys file and tried to restart it. It crashes and show the error agsin. The logs don't show up anything unusual. I also see in the logs: Oct 25 22:50:07 server postfix/virtual[24712]: 48BA5904990: to=<carlatf(a)ithaki.net>, relay=virtual, delay=1, status=deferred (mailbox /var/spool/vmail/ithaki.net/carlatf: cannot open file: Is a directory) Of course it's a directory!. I created it following the guide! I reinstalled Dovecot with the latest sources and nothing. I also turn off SSL from dovecot's config file, nothing. Any ideas dovecot gurus!? Best regards, Carla

[Dovecot] Clustering (replication and proxying) plans for the future
by Timo Sirainen 27 Oct '06

27 Oct '06

I wrote this mostly so that I won't forget my thoughts. Most likely won't be implemented anytime soon. I haven't thought through all the locking issues. It would require a distributed lock manager in any case. I think there are already several existing ones, so one of them could probably be used for Dovecot. Each mail server would consult a master server for getting namespace configuration and location for shared/public mailboxes. If the data is stored in some central SQL server there could just as well be multiple master servers (or even each server be their own master). Whenever trying to open a shared mailbox that doesn't exist in the current server, the imap process would automatically create a new connection for the destination server and start proxying the data. The proxy would be a somewhat dummy proxy, which just forwards the client's commands to it and doesn't even try to understand the replies from the remote server. So admin will have to be careful to use only servers which have all the capabilities that were announced by the original server. So, then the replication. Each namespace could be configured to be available either by proxying or by replication: namespace public { prefix = example/ location = proxy:imap.example.com } namespace public { prefix = example/ replicated_to = host1.example.com host2.example.com # If multi-master, we'll need to use global locking. If not, the # replicated_to servers contain only slaves. multi_master = yes location = maildir:~/Maildir } The way this would work is that each imap process connects via UNIX socket to a replication process, which gets input from all the imap processes. The replication process keeps track of how much has been sent to each other server and also the acks it has received from them. So if the network dies temporarily it'll start writing the changes to the disk until it reaches some limit, after which a complete resync will be necessary. Dovecot already writes all the changes to a mailbox first to a transaction log file and and only afterwards it updates the actual mailbox. The contents of the new mails aren't stored there though. The replication could work simply by sending the transaction logs' contents to the replicatio process which passes it onto other servers, which finally sync their local mailboxes based on that data. Since Dovecot already is able to sync mailboxes based on the transaction log's contents this should be pretty easy to implement. Of course the new mails' contents also have to be sent. This could be prioritized lower than the transaction traffic, so that each server always has very up-to-date view of the mailbox metadata, but not necessarily the contents of all the mails. If the server finds itself in a situation that it doesn't have some specific mail, it'll send a request to the replication process to fetch it ASAP from another server. The reply will then take the highest priority in the queue. Normally when opening or reading the mailbox there's really no need to do any global locking. The server will show the mailbox's state to be what it has last received from the replication process. Whenever modifying the mailbox a global lock is required. Here's also the problem that if the network is down between two servers, they both think that they got the global lock. If they did any conflicting changes, they'll have to be resolved when both of them again see each others. Dovecot's transactions in general aren't order-dependent so most of the conflicts can be resolved by just having the replication master decide which way the transactions were done and then sending the transactions back to all of the servers in that order. Adding new messages is a problem however. UIDs must be always growing and they must be unique. I think Cyrus solved this by having 64bit global UIDs which really uniquely identify the messages (ie. first 32bits contain server-specific UID), and then the 32bit IMAP UIDs. If there are any conflicts with the IMAP UIDs, they're given new UIDs (which invalidates clients' cache for those messages, but that can't be helped). Resyncing works basically by requesting a list of all the mailboxes, opening each one of them and requesting new transactions from the log files with <UID validity>, <log file sequence>, <log file offset> triplet. If UID validity has changed or log file no longer exists, a full resync needs to be done. Also if the log file contains a lot of changes, it's probably faster to do a full resync. Full resync would then be just sending the whole dovecot.index file. Conflict resolving could also require a full resync if transaction logs were lost. That'd work again by the master receiving everyone's dovecot.index files, deciding what to do with them and sending the modified version back to everyone. Each server has different transaction logs, so the log file sequences can't be directly used between servers. So the replication process probably will have to keep track of every server's log seq/offset. Also when receiving full dovecot.index files they'll have to be updated in some way. Then there's the problem of how to implement the receiving side. If the user already has a process connected to the replication process it could be instructed to update the mailboxes. But since this doesn't happen all that often, there also needs to be some replication-writer process which writes all the received transactions to the mailboxes. Now, when exactly should these replication-writer processes be created then? If all users have the same UNIX user ID, then there could be a spool of processes always running and doing the writing. Although this worries me a bit since the same process is handling different users' data. More secure way, and the only way if users have different UNIX UIDs, is to launch a separate writer process for each user. It probably isn't a great idea to do that immediately when receiving data for a user, but to queue data for the user for a while and then once enough has been received or some timeout has occurred, the writer process would be executed. There probably should be some shared in-memory cache with a memory limit of some megabytes, after which data is written to disk up to a configurable amount. Only after that is full or timeout for the user is reached, the writer process is executed and the data is sent to it. All this replication stuff could also be used to implement a remote mail storage (ie. smarter proxying). The received indexes/transactions could simply be kept in memory, and all the mails that aren't already cached in memory could just be requested from the master whenever needed. I'm not sure if there's much point in doing this over dummy proxying though.

I found a plugin for dSPAM on this mailing list (http://thread.gmane.org/gmane.mail.imap.dovecot/4632/focus=4632) that was very useful to me. I just modified the code to work for SpamAssassin instead. The purpose of this plugin is to watch the mail that is in the user's spam folder. If the user manually moves a piece of mail into the spam folder then the mail must have been spam that was incorrectly classified. This plugin causes SpamAssassin to relearn that mail as spam. Anyone else who finds this functionality useful is welcome to follow the link below. . http://chad.parry.org/software/dovecot/ - Chad Parry

[Dovecot] mail_extra_groups and home directory permissions
by Joe Cooper 26 Oct '06

26 Oct '06

Hi all, I've got a virtual hosting environment, where each user lives in /home/domain/homes/user, and the mailbox is Maildir within that directory. I've been running into a permissions problem, because it seems Dovecot doesn't get the users group membership (which seems odd, but I'm not confident enough of my comprehension of Dovecot to call say it looks like a bug). In short, when Dovecot hits the /home/domain directory which is owned by domain:domain and set to 750 permissions, it gets a permission denied, despite the user having the needed group membership to traverse these directories. So, in an effort to work around this problem, I came upon the mail_extra_groups option, which seems to allow me to drop dovecot into additional groups. If I add the domain group to this list, dovecot is able to traverse to the correct directory and all works exactly as I want it to with the domain directories being set to 750 permissions. Hooray! My only question, since this is not the documented purpose of this option, is: Is it safe to do this? Am I opening up some other kind of security problem by setting this option to include all domain groups? Thanks for any thoughts anyone might have on this...

[Dovecot] "Real" users AND Virtual users
by Muhamad A. Martoprawiro 25 Oct '06

25 Oct '06

Dear all, How can I use dovecot for both "real" users and virtual users? I could configure dovecot for real users, by using these lines in /etc/dovecot.conf: default_mail_env = maildir:%h/Maildir auth default { passdb pam { } userdb passwd { } } To accept virtual users, I used these lines: default_mail_env = maildir:/usr/local/virtual/%u/ auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } But, again, how to accept both kind of users? I use Postfix as mail server, and use LDAP/PAM for real users that have home-directory on the system. My OS is Mandriva 2007, and I use dovecot that is bundled as an RPM package (dovecot 1.9 rc7) in the OS. The content of file /etc/pam.d/dovecot: #%PAM-1.0 auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth Thanks. Regards, Muhamad

[Dovecot] performance problems with rc10 and solaris 10

Hi, i have 2 dovecot imap server running on solaris 10 The primary server with dovecot 1.0.alpha4 is running with best performance on Sun Sparc E4k5 with 8x 450MHz The secondary with rc10 has ugly performanceproblems on Sun E450 wth 4x 450MHz. Every new imap process takes permanent 25% cpu usage List the folder and fetch message are both slowy! Both servers are configred with ldap backend preventive i deleted for rc10 the complet index and controlfiles, because the spooldir is a sync from the masterserver with dovecot alpha4. I thought its a little bit slowy because of my 30.000 mails. the indexfiles are created now, but the still ugly slow .... For debugging i compiled rc10 again --with-debug=yes and start dovecot with solaris truss truss tells nothing to explain this behavor logentrys from dovecot has this warnings: --> dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing pool 'storage' with: 1024 dovecot: Oct 18 14:51:47 Info: IMAP(saar): dirsize quota limit = 750000kB dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 32768 dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 65536 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing data stack with: 131072 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing pool 'uidlist record_pool' with: 32768 <-- also i compiled rc10 --with-notify=none, no result to ensure it isn´t the solaris system, i compiled alpha4.

[Dovecot] Unsolved : mbox-sync-rewrite.c : assertion failed
by Jakob Curdes 25 Oct '06

25 Oct '06

Some days ago I wrote about an inaccessible mailbox after an upgrade from 0.99.14 to 1.0rc10. Today I get this problem with another mailbox but it seems to be it is not only related to the upgrade : - user comes back from holiday, does not see his inbox : dovecot: Oct 24 18:51:09 Error: IMAP(abcd): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) (he accessed it last with the old dc version) Solution : moving account to other server, copy everything over to the old account and it worked. This is what I did and afterwards the mailbox was readable. Now the user goes back to his PC (I made my work from another machine) and opens his mailclient (with the still existing account) and BINGO dovecot crashes again on the mailbox as berfore. Once ist has crashed on it, it than crashes always, even if you make a new account or remove the index. So I suppose it has rather to do with cached information in the client than with the upgrade itself. But nothing the client sends should be able to crash the server ! Hoping for an idea, Jakob Curdes

[Dovecot] Status of Shared Folders?
by Charles Marcus 24 Oct '06

24 Oct '06

Hi Timo, I'm just curious... is the Wiki up to date regarding the status of Shared Folder support for Dovecot? Specifically, does Dovecot still have a problem with Read-only (for certain users) maildirs using Shared folders defined via namespaces? I'm about ready to start testing a rollout, but wanted to find out what to expect with regard to Shared Folders - we use them extensively right now (Courier-imap), so it is important for us. Having per-user read/unread flags will be a very nice bonus, but I don't see anything about support for those... -- Best regards, Charles Marcus I.T.

[Dovecot] converting from courier questions
by Aaron P. Martinez 24 Oct '06

24 Oct '06

I currently run postfix and courier on my mail servers with squirrelmail. The problem with courier is it seems to run so slow. The webmail takes forever to load if you have many mails. I have this set up in virtual domains with all longin and path info in an mysql database. I just joined the list and DID google before asking, hope this isn't a common question. With courier it looks for a "homedir" and then a "maildir".. I tried doing a query as such: user_query = SELECT Homedir and Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' to no avail, is my sql wrong or can you not cat the homedir and maildir fields together to create the complete path to home? . i got around the homedir problem by setting mail_chroot = /var/spool/postfix/virtuals (is this the general way, only way?) and then in my dovecot-mysql.conf i have user_query = SELECT Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' This almost worked but as i was watching the logs it was looking for /var/spool/postfix/virtuals/<somedomainname>/Maildir//Maildir In courier the "Maildir" is not implied, it has to be spicified in the database. I have a LOT of users and would love to avoid chaning every line in my database. or add another filed just for dovecot. I would also like the ability to switch back and forth for testing with courier.. Is there anyway that this can be done? Thanks in advance, Aaron

[Dovecot] Creating MySQL db
by Gerard Seibert 24 Oct '06

24 Oct '06

I was just wondering if anyone was using or aware of a program to create MySQL Data Bases for use with Dovecot. For Postfix, there is the 'Postfixadmin' application. I have not seen anything similar for Dovecot and was wondering if one existed. My system consists of all virtual users. -- Gerard Never attribute to malice what can adequately be explained by incompetence.

[Dovecot] problems with authentication
by Paul Aguirre 24 Oct '06

Hi, I have some problems I'm using fetchmail to get my mail from the server to a local server, but the problem is that my user name of the mail is "user@virtualdomain" and I can't make a system user with "@" on centos. So, I want to know how can I tell to dovecot the user "user@virtualdomain" is associate to a sistem user "user.virtualdoman". Or if any one knows another solution.

[Dovecot] Proxy using passd file
by Clayton Epp 23 Oct '06

23 Oct '06

I'm trying to create a proxy using passwd files. Can I use the existing passwd files created by the system (ie passwd and shadow) or do I have to create new passwd files for the email proxy users? How would the passwd and shadow files for a proxy using passwd files look? I've tried the example on the wiki but I'm not getting anywhere, pop and imap requests are not getting sent to the other server.

The problem appears only when the ldap connection breaks (e.g. remote ldap server restart). We don't use rootbinddn at all. Anyway I just checked the latest version of nss_ldap and now I see interesting new relevant options are available (e.g. nss_connect_policy persist/oneshot). I will give it a try and respond back in a few days. Definately nss_ldap's bad behaviour is not really a dovecot problem.

I was using dovecot ->getpwent -> nscd -> nss_ldap -> LDAP. I found out that whenever the ldap server got restarted, nscd did not restart properly and immediately its permanent ldap connection, and was giving 'user unknown' replies at least for a few minutes. Restarting nscd would fix the problem immediately. Running without nscd would also fix the problem. There was no problem with pam_ldap authentication. As a result, the system got ignorant of its uncached users for a few moments. My workaround was a crontab that kept /etc/passwd up-to-date as well as an entry in the /etc/resolv.conf 'passwd: ldap files' (cat /etc/passwd ; getent passwd ) |sort -u >/etc/passwd.tmp && mv /etc/passwd.tmp /etc/passwd > So should I have the indexes on the fileserver (one instance), or should they > be on each cluster machine's private storage (possibly several instances; > one per cluster machine)? The suggestion is that if you need to have mailboxes over NFS, use local disk for indexes. If you read the complete list archive you will find too many people that have had troubles with indexes over NFS. Local indexes have a performance penalty, only when you have access from different imap servers (especially concurrent) . apap

[Dovecot] mysql-5.0.26 stored procedure authorization, take 2
by Chaos Engine 22 Oct '06

22 Oct '06

Last time I came up with a problem with concernin MySQL authorization with stored procedures. Timo helped me get going by with modified client_flags (MULTISTATEMENT keyword). Now all it happened again but from another way. My stored proce for MySQL is causing fillowing error: "Oct 21 12:39:22 haos dovecot: auth-worker(default): sql(user,192.168.X.X): Password query fai led: Commands out of sync; you can't run this command now" Looks like it is partly mysql-5.0.26 thing because of this: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html On the other hand with my previous mysql installation (mysql-5.0.24-r1) this error is gone (I checked by downgrading). My dovecot-sql.conf: driver = mysql connect = host=/var/run/mysqld/mysqld.sock dbname=mailbase user=mailuser password=******** client_flags=65536 #655536 is equivalent of CLIENT_MULTI_STATEMENTS flag #yes, I still insist on using stored proc for authorization. This gives me few usefull features I like. password_query = call Authenticat('%u', '%n', '%d') With this config on mysq-5.0.26 I get "...Commands out of sync; you can't run this command now..." but not on mysql-5.0.24-r1. Personally I think mysql guys changed something; I can't tell what and why (changelog review?) Maybe you guys know what it was? -- Chaos greets U

[Dovecot] Using saslauthd with dovecot

[Dovecot] Virtual Users
by Gerard Seibert 20 Oct '06

20 Oct '06

Dovecot 1.0.rc7 Postfix 2.4-20061006 FreeBSD 6.1 STABLE I have dovecot up and running with postfix. I now want to switch over to a system using purely virtual users. I have gotten postfix configured to deliver the mail to virtual mailboxes correctly. The problem I am having is with dovecot. After configuring the dovecot.conf file, dovecot will POP mail from the virtual mailboxes. However, that is only for users who are in the /etc/password file. I will have a large number of users who are truly virtual and therefore not be in that file. I know I am dumb, but I do not know how to set up either a MySQL data base, or just a plain flat file with the required information. I tried Googling, but I cannot find the exact syntax to use. Perhaps someone could point me in the right direction or give me a brief example of how to go about this. Thanks! -- Gerard "It is not the OS's job to stop you from shooting your foot.

[Dovecot] Problem with indexes
by crs 20 Oct '06

20 Oct '06

Hello. Dovecot is really good software but I have one big problem with indexes. I have server with a lot of mailboxes - filesystem has quota enabled and I can't resign it from different reasons. When mailbox achieve quota size and user wants to pick mails via pop3, error "-ERR Mailbox is in inconsistent state, please relogin." is given. I know it's because dovecot can't write indexes. Is it possible to force dovecot to write indexes with definite owner/group f.e dovecot/dovecot and not owner/group of mailbox? I can set quotas for user dovecot to unlimited and problem would disappear. Thanks in advance for any answers.

[Dovecot] Subscription file
by Steven F Siirila 19 Oct '06

19 Oct '06

Background: We are a UW-IMAP shop, using mbox format. (!) We are in the process of upgrading to Dovecot, hopefully to 1.0 proper. :) One of the modifications we have been using in test versions of Dovecot involve the move of the user subscription file from: IMAP-root/.subscriptions to: $HOME/.mailboxlist Rather than having to make changes to Dovecot source code each time a new release comes out, it would seem to make sense to have a way to configure this from dovecot.conf. Something like: # Default (%i denotes IMAP root): #imap_subscription_file = %i/.subscriptions # UW-imap-style (%h denotes home directory): #imap_subscription_file = %h/.mailboxlist While it makes sense to me to have the subscription file where it is in Dovecot by default, it would be a substantial undertaking to determine where to move the .mailboxlist to in our environment for each user, since there is no easy way to determine what a user's IMAP root directory is set to in their client.

[Dovecot] Urgent - Inconsistent Inboxes
by Jakob Curdes 19 Oct '06

19 Oct '06

Hi, An urgent problem that I have : runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, nothing. For this machine we have a backup server rsyncing everything over. Now the main server went down and we started DC on the backup machine some day ago. Everything went well, besides one problem : people complained about missing mails that they had seen beforehand. When looking in the inbox, they were all there. After recreating the imap account (outlook express) or deleting the cache file (thunderbird .msf files) everything was well. But you can't really recreate all accounts after switching to the backup machine every time.... today we went back to the main server and in advance I deleted all .imap.index files hoping that they might have been the eventual cause of the problem, but no, same thing happens again. It now seems to me that this is a pure client issue, but nevertheless two questions : a) who knows a way to tell the client (OE or TB in this case) to disregard all local information and get everything fresh from the server ? b) Can this behavior be influenced from the server side? I know I'm behind with 0.99.14 but up to now there was no problem and "never change a running system". If upgrading could help, I would do it immediately. Any hints welcome, especially fast ones as tomorrow morning I have to get the clients running. Yours, Jakob Curdes

[Dovecot] Logging authentication failures?
by dri 19 Oct '06

19 Oct '06

I use a script that watches log files looking for failed ssh login attempts and adds firewall rules when there are enough login failures within a certain amount of time. I would like to apply this to Dovecot to automatically firewall attackers trying to brute-force an IMAP account. Is there a way to make Dovecot log authentication failures (I'm running 1.0.rc10)? In other words, can I configure Dovecot to put something in the log the instant "NO Authentication failed" is sent to the IMAP user? With "auth_verbose = yes" I can see individual authentication mechanisms fail, but I have multiple passdb sections so a failure in one mechanism doesn't mean a complete login failure. Thus, configuring the script to watch for individual mechanism failures may result in the firewalling of legitimate users. Thanks for any info!

[Dovecot] passdb checkpassword and lastauth
by Max A 18 Oct '06

18 Oct '06

Hi. If checkpassword interface is used for working with vpopmail, function vpopmail "Record time and ip of last auth attempt" (--enable-auth-logging option for configure) won't work - the file "lastauth" is created in Maildir, but does not contain ip-address. If I had correctly understood, dovecot woldn't have set a enviroment variable TCPREMOTEIP for vchkpw. If changes are made in auth/passdb-checkpassword.c (a patch in attachment), everything will work. Probably, the patch is incorrect and does not solve all problems, however the request is to pay attention to existence of the problem. Also it is possible, that a similar problem exists with other variables TCP UCSPI protocol (http://cr.yp.to/proto/ucspi-tcp.txt) P.S. If use the interface vpopmail instead of checkpassword, the file "lastauth" will not be created at all, that is a little bit inconvenient. ********************************** System: dovecot-1.0.rc10 vpopmail-5.4.17 ASP Linux Server II (RHEL3 clone) kernel 2.4.21-47.EL.aspsmp CPU architecture: x86 (IBM xSeries 336) Filesystem: ext3 ********************************** dovecot configuration: base_dir = /var/run/dovecot/ protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes login_greeting = Ready. first_valid_uid = 89 last_valid_uid = 89 first_valid_gid = 89 last_valid_gid = 89 protocol imap { listen = 81.26.136.8:144 mail_executable = /usr/local/libexec/dovecot/imap mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { listen = 81.26.136.8:112 login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = %f mail_plugins = quota mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb checkpassword { args = /var/qmail/vpopmail/bin/vchkpw } userdb prefetch { } user = root } dict { } plugin { quota = maildir } *************************************** dovecot configure options: ./configure \ --disable-ipv6 \ --prefix=/usr/local \ --sysconfdir=/etc/dovecot \ --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --with-checkpassword \ --with-vpopmail \ --without-static-userdb \ --with-prefetch-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --with-ssl=openssl \ --with-pop3d \ --without-deliver \ --with-storages=maildir \ --with-docs ***************************************** vpopmail configure options: ./configure \ --enable-auth-module=cdb \ --enable-logging=p \ --enable-md5-passwords \ --enable-make-seekable \ --enable-file-sync \ --enable-ip-alias-domains \ --enable-clear-passwd \ --disable-roaming-users \ --disable-learn-passwords \ --disable-passwd \ --enable-auth-logging diff -ur dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c dovecot-1.0.rc10/src/auth/passdb-checkpassword.c --- dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c 2006-08-22 06:37:56.000000000 +0400 +++ dovecot-1.0.rc10/src/auth/passdb-checkpassword.c 2006-10-17 16:47:09.000000000 +0400 @@ -226,6 +226,10 @@ env_put(t_strconcat("REMOTE_IP=", net_ip2addr(&request->remote_ip), NULL)); + env_put(t_strconcat("TCPREMOTEIP=", + net_ip2addr(&request->remote_ip), + NULL)); + } if (request->master_user != NULL) { env_put(t_strconcat("MASTER_USER=",

Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

[Dovecot] autoconf check for ldap not linking with -lber
by Jorgen Lundman 18 Oct '06

18 Oct '06

Maybe not a big deal, but generally you (used to?) link against both: configure:31276: checking for ldap_init in -lldap configure:31311: gcc -o conftest -std=gnu99 -I/usr/local/include -Wall -W -Wmiss ing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat =2 -Wbad-function-cast -I/usr/sfw/include -L/usr/local/lib conftest.c -lldap -lsocket -lnsl -lrt -lsendfile >&5 Undefined first referenced symbol in file ber_sockbuf_io_readahead /usr/local/lib/libldap.so ber_sockbuf_alloc /usr/local/lib/libldap.so ber_sockbuf_io_fd /usr/local/lib/libldap.so But could be special situation as my LDAP version is fixed, due to production environment using it. It also failed when OpenLDAP was linked against OpenSSL, since it does not try with the SSL libraries.

[Dovecot] Strange POP3 problem...
by Mike Cisar 18 Oct '06

18 Oct '06

I've been having this problem for a long time now. It started when I first began to use Dovecot (0.9x) and seems to have been occurring more and more frequently as we've progressed through the betas and now into RC7. I have been kind of chaulking it up to a "user issue" since the problem only seems to occur for one user (who has one machine at his office, and one at his weekend cabin... problem occurs with equal frequency on both of his machines). Lately it's been occurring about once every couple of days, but still nothing that I have been able to reproduce with any particular email or frequency. However as luck would have it the problem occurred today while I was onsite at the client's office so I was at least able to see that end of things at the same time. Essentially the user will have a number of messages in their mailbox (today for example 13) the download of mail will go just fine until one particular message and then the download will just stop, eventually returning an error message. Trying to receive mail again will retrieve messages 1-9 again and fail in the same spot. If you log in via IMAP and delete the following message (ie. the message after the one that was last received) you can then POP for mail again and the remaining messages in the mailbox will download. In the log all we see is the following (over and over)... Aug 28 16:14:51 mail dovecot: pop3-login: Login: user=<xxxxx>, method=PLAIN, rip=vvv.www.xxx.yyy, lip=vvv.www.xxx.yyy Aug 28 16:15:32 mail dovecot: POP3(xxxxx): Disconnected top=0/0, retr=9/170375, del=0/13, size=1349520 >From the client side I get the following in Outlook Express... "Your server has unexpectedly terminated the connection..." "...POP3, Server Response: '+OK 795 octets'..." Interestingly 795 bytes is the size of the "bad" email (the one that won't download). Any thoughts? Cheers, >>>>> Mike <<<<<

[Dovecot] Index files
by Steven F Siirila 17 Oct '06

17 Oct '06

I am doing some testing with Dovecot and wondered if it was normal for the deliver program to create index files for an Inbox (the test Inbox is over 7MB), but to not update the index files after the initial creation, even though messages continue to come into the mailbox. Note that during this testing, no IMAP or POP accesses are being made. Would it matter if a command-line program such as mutt were reading/updating the Inbox in question? Shouldn't Dovecot delivery be continually updating the index files as new messages arrive in the Inbox? -- Steven F.

[Dovecot] dovecot tpop3d UIDL mbox
by antencek＠volja.net 17 Oct '06

17 Oct '06

Hello All! I am new to this list so I hope I'm not in the wrong list with my question. First, I have to say that dovecot is (in my opinion) one of the best POP3/IMAP servers arround. I especialy like its' simplicity (configuration) and powerfullness (speed, auth mechs). In my production environment I would like to cange from tpop3d to dovecot, but I have only one little problem :). This is my situation: pop3 server: tpop3d mail fromat: mbox (/var/mail/username) UIDL: tpop3d UIDL format Since there are users who let mail on server, I need to keep UIDL. The problem is that the patch which gives dovecot the capability to replay with tpop3d UIDL format apparently works only on maildir mailboxes. Is there any resonable solution to my problem? TIA. Regards, Antencek

Hi. I want to use allow_nets in my configuration, but i have some troubles which i cant resolve. To use allow_nets i creates `allow_nets` text field in my mysql users table. My query is: from: dovecot/sql.conf: password_query = SELECT crypt as password, maildir as userdb_mail, 6 AS userdb_uid,6 AS userdb_gid, allow_nets FROM users WHERE id = '%u' from dovecot.conf: auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot/sql.conf } userdb prefetch { } user = root } To check this i added address 193.193.193.100/32 (which is not my address) and tried to connect from localhost (using telnet). And it allow me to connect! May be i did something wrong, but i cant explain this, so i`m asking for your help.

The alarming aspect of the corruption is when it occurs at the beginning of an email (i.e. ^@^@^@From:...). Emails can be lost/appended to the bottom of the previous email. I've seen this problem several times on our deployment and tracked it down to what appears to be NFS locking issues. Are you storing mails on an NFS mounted filesystem? If so check the following... http://wiki.dovecot.org/NFS We're running dovecot-1.0 beta5 (admittedly not an rc version but >beta4 which is mentioned in the NFS wiki section) so I'm not sure the mbox rewrite from v0.99.x has fixed the problem. We had several applications accessing the mbox (Dovecot and Pine mainly). Reconfiguring Pine to use IMAP (using Dovecot) rather than write to the mbox directly appears to have fixed the problem and we have had no corruption for several months now. So, my question is am I wrong to assume NFS locking/corruption? Does anyone know if this is really a Dovecot or NFS issue? Phil

[Dovecot] 1.0.rc9 released
by Timo Sirainen 17 Oct '06

17 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz.sig Most importantly this should fix the login process problems that people have been reporting. There were also some bugs in the proxying feature. Also note the 64bit change in dovecot.index.cache files. Unless you delete dovecot.index.cache files manually, you'll these kind of error messages into your logs: Error: Corrupted index cache file ...dovecot.index.cache: registered field date.sent size changed They'll get fixed automatically of course, but it might be a bit annoying to see them. * 64bit systems: dovecot.index.cache file will be rebuilt because some time fields have been changed from 64bit fields to 32bit fields. Now the same cache file can be used in both 32bit and 64bit systems without it being rebuilt. * Added libmysqlclient workaround to conflicting sha1_result symbol, which caused Dovecot to fail logging into MySQL. + dovecot.index.cache file opening is delayed until it's actually needed. This reduces disk accesses a bit with eg. STATUS commands. + auth_cache: Try to handle changing passwords automatically: If password verification fails, but the last one had succeeded, don't use the cache. This works only with plaintext auth. - dovecot.index.cache: We didn't properly detect if some fields were different length than we expected, which caused assert crashes - Lots of fixes to login/master process handling - mbox: Fixed a bug causing "X-IMAPbase uid-last unexpectedly lost in mbox file" errors, and possibly others.

[Dovecot] Separate auth for pop and imap
by Hr. Daniel Mikkelsen 17 Oct '06

17 Oct '06

Hi. Is it possible to set up separate authentication backends for POP and IMAP for a single Dovecot instance? Or does this require two separate dovecot instances with separate config files? Specifically, I want to have one database query for IMAP and one for POP so that I can let these be separate features that I can flag in a database. -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] MBox path
by Rick 17 Oct '06

17 Oct '06

Hi, I'm having great difficulty pointing Dovecot to my MBox files. They are all in /var/spool/mail/username as textfiles.. not directories. So my guess was: default_mail_env = /var/spool/mail/%u Since %u is user. If the user is "server" I would expect it to go to /var/spool/mail/server exactly what I want. But it doesn't /var/spool/mail///home/server. If I create the directory home in /var/spool/mail and make a symlink of the username pointing to /var/spool/mail it does work. But that's a very dirty workaround I rather not use, also because we have a lot of users.. a lot of symlinks. If I set default_mail_env = /var/spool/mail, it also searches for /var/spool/mail///home/server. I feel like I've tried everything. What am I doing wrong? I'm using version 1.0.beta8, included in Fedora Core 5. Thanks, Rick

[Dovecot] Dovecot still failing with RC10...
by Timothy Meader 16 Oct '06

16 Oct '06

Hello, I mentioned back with version RC8 that dovecot was having an issue with the first login working, but all subsequent attempts failing with the error message: "Error: Maximum number of mail processes exceeded" in the dovecot log file. This is with an unchanged working conf file from RC7 (which, aside from comments, nothing has changed config-wise in the conf from version RC7). Now, the max mail processes were already set at 1024 (and I'm the only person using this server while testing), but just for the heck of it, I tried bumping the number up to 4096 and giving it another shot. No such luck. You can login once, but any subsequent attempts come back with the error I mentioned. This is making all versions above RC7 unusable for me unfortunately. I was hoping to get buy-off on switching from QPopper/UWImap to an all Dovecot solution with the pending 1.0 final, but I doubt they'll go for allow and RC being run on the production side. Two notes that might help(?): -I'm running this on Solaris 9, not a Linux box -Dovecot is not running in daemon mode, it's running through xinetd Here are the xinetd.conf sections that are relevant: defaults { #The maximum number of requests a particular service may handle # at once. instances = UNLIMITED # The type of logging.

[Dovecot] indexes?
by David Lee 16 Oct '06

16 Oct '06

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.). So locking is an important consideration. Decent "noac,actimeo=0" seems to address this succcessfully. But indexes... What is the best place for the index files? Logically alongside the INBOX area on the shared-NFS area? Or within each UN*X machine? (Or something else?) And why? Is there documentation of what functionality the index files provide, and how, if at all, this interacts with the locking of INBOXes (and folders). Thanks. -- : David Lee I.T.

[Dovecot] quota dict (mysql)
by Peter Veerman 16 Oct '06

16 Oct '06

Hi, I have dovecot configured to make use of the dict (mysql) plugin in order to keep track of the used quota. First, as you can see in the mysql table output below it seems that values aren't stored correctly. Secondly I get all kinds of database related errors in my mail logs. The (relevant) sections of the configuration files are also included below. My question is, what am I doing wrong?

[Dovecot] System-wide sieve script?
by Ty! Boyack 16 Oct '06

16 Oct '06

In the dovecot LDA documentation, it mentions having sieve scripts located in ~/.dovecot.sieve, which works great for per-user sieve code. I was trying to find out if there was a system-wide sieve script (maybe /etc/dovecot.sieve?) that would hopefully be run first, followed by any per-user sieve code. Anyone know if this is already possible, or if not, if there are any plans to implement this? I'm assuming one could make a kludgey fix by having every .dovecot.sieve include a system-wide file, but that would allow a user to remove that "include" if they choose. I'd like to have a centrally controlled, immutable set of rules that all mail goes through. If I missed something in the wiki or archives, I offer my apologies in advance. Thanks! -Ty!

[Dovecot] LDAP Memory Leak
by Daniel 16 Oct '06

16 Oct '06

Hi Timo I use LDAP auth on a system with around 2000 email account. I use dual OpenLDAP servers. I haven't noticed a leak of memory. Is there any more information and I will have a look to see if I can see anything that might help. Is it only affecting certain machines or all? Regards Daniel Rowe Date: Mon, 16 Oct 2006 02:39:26 +0300 From: Timo Sirainen <tss(a)iki.fi> Subject: [Dovecot] 1.0.rc10 released To: dovecot-news(a)dovecot.org, dovecot(a)dovecot.org Message-ID: <1160955566.5448.126.camel@hurina> Content-Type: text/plain; charset="us-ascii" http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

[Dovecot] Apple Mail quota display
by Timothy Martin 16 Oct '06

16 Oct '06

I know this isn't necessarily a dovecot issue, but I was wondering if anyone has the quota displaying correctly in Apple Mail? I have it set up and working and displaying properly in thunderbird, roundcube (webmail), and squirrelmail. But for some reason Apple's Mail doesn't show the values or its nice thermometer bar. Are there additional configuration options for quota not documented on the wiki? .tim

[Dovecot] Duplicate mails
by Vegar Nilsen 16 Oct '06

16 Oct '06

Hi, one of our customers reported a problem after we moved her maildir to another disk. (Jail in FreeBSD 6, moved to another disk with rsync.) For some reason she's seeing duplicates of almost every message from November, 2005 until June, 2006 (the move happened in September, 2006.) It seems like these mails have been respooled somehow and been inserted into the maildir with the same date and time as the original: root#loc [</var/gopostal/maildirs/wow/lina/cur>] diff 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf -rw------- 1 mailnull mail 7755 Nov 24 2005 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac -rw------- 1 mailnull mail 7755 Nov 24 2005 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac As the diff command shows these mails are identical, except that one was created about 10 months after the other. 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac was written by Exim in November (we've configured Exim to add the size (",S=7755") to the file name), but I have no idea where the other file comes from. Could this be Dovecot that has recreated these mails for some reason? (Since the file names are different I doubt that this happened during the rsync, instead it must come from some program that conforms to the maildir standard of naming files. The mailserver had a different name back in November, mail9 was the old name, locusts is the new one.) Originally this file 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf was named 1158863410.P19488Q34M511758.locusts.copyleft.no:2,bf which, if I understand it correctly, means it's unread. (The customer has deleted it since reporting this problem.) root#loc [</var/gopostal/maildirs/wow/lina/cur>] uname -r ; dovecot --version ; exim -bV 6.1-RELEASE 1.0.beta3 Exim version 4.60 #0 (FreeBSD 6.0) built 22-Feb-2006 13:01:52 If anybody has an idea as to what caused this I would really appreciate any pointers or info.

[Dovecot] Authenticating dovecot against Active Directory using bsdauth and login_ldap
by Martin Croker 16 Oct '06

16 Oct '06

All, I'm working in a multi-platform environment where user accounts are already held in Active Directory. I'm been trying to setup dovecot to perform user authentication against Active Directory using ldap. My Environment is: Platform OpenBSD 3.9 Dovecot Version 1.0.rc7 Active Directory Windows 2003 The approach I've taken (being the only one I was able to make work) is to use login_ldap to perform bind authentication against Active Directory/LDAP and authenticate dovecot using bsdauth. As far as I can tell the dovecot ldap authentication module requires access to the encrypted password field to which Active Directory does not permit access. Simulated LDAP login fails and when debug is enabled writes the following to /var/log/maillog ==== /var/log/maillog ================ Oct 15 20:12:27 server dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=***********************== Oct 15 20:12:27 server dovecot: auth(default): bsdauth(mcrokerx,127.0.0.1): invalid password field Oct 15 20:12:28 server dovecot: auth(default): client out: FAIL 1 user=mcrokerx Oct 15 20:12:38 server dovecot: imap-login: Aborted login: user=<mcrokerx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured ======================================= It appears that the cause of these log messages are the following lines of code in src/auth/passdb-bsdauth.c ==== src/auth/passdb-bsdauth.c ======== 29 if (!IS_VALID_PASSWD(pw->pw_passwd)) { 30 auth_request_log_info(request, "bsdauth", 31 "invalid password field"); 32 callback(PASSDB_RESULT_USER_DISABLED, request); 33 return; 34 } ======================================= These lines seem to require that the pw structure contains the encrypted password in pw->pw_passwd. Where login_ldap is used against Active Directory the encrypted password is not available to bsdauth and instead pw->pw_passwd contains '*'. If auth_userokay is called independently it is however able to authenticate the user correctly, as such I wonder if the IS_VALID_PASSWD check is actually necessary. It could be that my entire approach is wrong in which case I'm happy to be put right; however it seems that lines 29-34 need modification to correctly support this behaviour of bsdauth. This is beyond my limited ability in c but temporarily removing these lines of code from passdb-bsdauth.c has enabled me to authenticate dovecot against login_ldap (and thereby against Active Directory). My config files are: ==== /etc/dovecot.conf ================ base_dir = /var/dovecot/ ssl_cert_file = /etc/ssl/certs/server.crt ssl_key_file = /etc/ssl/private/server.key disable_plaintext_auth = no login_dir = /var/dovecot/login login_user = _dovecot mmap_no_write = yes protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain passdb bsdauth { } userdb passwd-file { args = /etc/passwd } user = root } plugin { } ======================================= ==== /etc/login.conf (exert) ========== staff:\ :auth=-ldap:\ :x-ldap-server=10.0.0.23:\ :x-ldap-port=389:\ :x-ldap-noreferrals:\ :x-ldap-uscope=subtree:\ :x-ldap-basedn=dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-binddn=cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-bindpw=mypassword:\ :x-ldap-filter=(&(objectClass=user)(mail=%u)):\ :datasize-cur=512M:\ :datasize-max=infinity:\ :maxproc-max=256:\ :maxproc-cur=128:\ :requirehome@:\ :tc=default: ======================================= Note: for login_ldap to work it is necessary that the user information (minus password) is replicated on the localhost. I've done this using a relatively inelegant script which for completeness is below. I guess adding some error checking would be a good idea. ==== ldapsync.ksh ===================== #!/bin/ksh ldapsearch -h 10.0.0.23 \ -D cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -b cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -w mypassword \ -v \ -x "(objectClass=user)" | while read key value ; do if [ "$key" == name: ]; then ldap_name="$value" fi # User Mail field as Unix name - remove @my.domain.co.uk if necessary if [ "$key" == mail: ]; then ldap_mail=$( echo "$value" | sed 's/@.*//g' ) if ( id 2>/dev/null >/dev/null $ldap_mail ); then usermod -c "$ldap_name" -s osbin/nologin -g staff -L staff $ldap_mail else useradd -d /home/$ldap_mail -c "$ldap_name" -s /sbin/nologin -m -g staff -L staff $ldap_mail fi ldap_name="" ldap_mail="" fi done ======================================= Martin

[Dovecot] Messages not expunged
by Jackie Hunt 16 Oct '06

16 Oct '06

Hi all, I'm doing some testing between U of Washington IMAP server (which we currently run) and Dovecot on a IBM AIX system. I created a 50M mailbox, made up of 262 msgs. I'm using a Perl Script with the imap::client module to fetch each message and then flag it for deletion. At the end of the test, I run an expunge to delete all the messages. UofW imap server ran fine, messages gone. With dovecot I found the messages were not being expunged. The log indicated they were, but then said 262 messages existed at the end. After more checking, I found the file system I was using was low on disk space (<50M). As soon as I added more disk space, and reran the test with dovecot the messages were indeed expunged. Is this normal imap protocol behavior? I thought I would see an error message or something in the dovecot log. Does dovecot duplicate the mailbox before expunge? There wasn't room on our system to do that. Thanks much for any insights/info.

[Dovecot] Restricting Services (POP or IMAP)
by Odhiambo WASHINGTON 15 Oct '06

15 Oct '06

It would be great to have a HOWTO in the wiki, on how to restrict services by username in dovecot, so some users are allowed IMAP and others not allowed. As concerns restricting users by IP, I believe that is a bad idea. It's almost a useless idea, imnsho, because they can connect from another IP. It's easy to restrict services by IP using a firewall or by using inetd. -Wash http://www.netmeister.org/news/learn2quote.html DISCLAIMER: See http://www.wananchi.com/bms/terms.php -- +======================================================================+ |\ _,,,---,,_ | Odhiambo Washington <wash(a)wananchi.com> Zzz /,`.-'`' -. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +======================================================================+ Don't take life too seriously -- you'll never get out of it alive.

[Dovecot] Dovecot rc9 error (More information)
by Daniel 15 Oct '06

15 Oct '06

Hi This happens when email is copied/moved from the inbox to another folder on the same imap account. The mail client goes into a loop with the below errors logged. This is on a 64bit Linux machine using the Maildir storage format. After doing a 'rm dovecot*' from the Maildir folder of the account having the problem the client can log in again but if the client tries to copy again it gets the same error. RC9 appears to be broken on this box. I have tested connecting form a windows machine and I get the same with thunderbird. I have tried with different accounts and they get the same problem. I have down graded to RC8 and all is working OK so seems to be a problem introduced with RC9. I have a 32bit Linux server with RC9 installed which has around 2000 accounts on it and this has no problems so maybe not affecting 32bit machines. If I can give any more information please let me know. Am getting this error with Dovecot rc9 on a imap account.

[Dovecot] MySQL stored proc authorization
by Chaos Engine 14 Oct '06

14 Oct '06

On my Gentoo box until today I had dovecot-1.0_rc7 and used following entry in /etc/dovecot/dovecot-sql.conf password_query = call Authorize('%u', '%n', '%d') Simply put dovecot is calling my mysql stored routine which handles authorization. Until today, when I updated dovecot to dovecot-1.0_rc8 it worked flawlessly. With this version executing stored proc dies with: Password query failed: PROCEDURE mailsql.Authorize can't return a result set in the given context Replacing stored proc call with select .... statement does the thing, but it's stored procedures are ... generally better to do things on DB imvho :-) Downgrading to dovetot-1.0_rc7 fixes the problem immediately. Of course /etc/dovecot/dovecot.conf remains the same in either case. Is this a bug or change made on purpose? -- Chaos greets U

[Dovecot] child 29480 (auth) returned error 89, FC5, Postfix, MySql, mbox....arghhhh
by Kent Iverson 14 Oct '06

14 Oct '06

Hi all, I have been putting a small (simple?)dedicated email server together to (ultimately) host a couple of domains. I am currently getting the configuration to work with one domain w/local mbox users and then plan to extend it to virtual users and an additional domain. Dovecot has been a problem to integrate in the configuration. The basic pieces are FC5, Postfix, Dovecot, with Cyrus-sasl and MySql user/password databases. I have installed, configured, and verified Postfix, Cyrus-sasl, and MySql both separately and working together. All applications are standard Yum sourced FC5 binaries. Dovecot, however, stubbornly refuses to join the party. I have searched for clues on-line and have not found anything that has helped, thus this message. The problem seems to be tied tightly to using mySQL as an access mechanism for passdb/userdb information since if I remove that access mechanism Dovecot runs fine. The reason I am looking to use mySQL is that it seemed an easy way to have a common database for user name and domain identification with a single common FQDN login authentication format for current local users and future virtual users. As I understand it, the default PAM passwd doesn't support FQDN user names. The symptom: =========== Dovecot starts and immediately exits. Maillog shows the following immediately after executing /sbin/service dovecot start Oct 12 21:36:24 Playtime dovecot: Dovecot v1.0.beta8 starting up Oct 12 21:36:25 Playtime dovecot: child 29479 (auth) returned error 89 Oct 12 21:36:25 Playtime dovecot: child 29480 (auth) returned error 89 Oct 12 21:36:25 Playtime dovecot: Auth process died too early - shutting down Oct 12 21:36:25 Playtime dovecot: auth(default): net_connect_unix(/var/run/dovecot/auth-worker.29480) failed: Permission denied Oct 12 21:36:25 Playtime dovecot: auth(default): net_connect_unix(/var/run/dovecot/auth-worker.29479) failed: Permission denied It appears that the dovecot-auth process is immediately exiting with a non-specific error (89) and no collateral info. There are two sets of error 89's because the process count is set to 2 in dovecot.conf (see below). Looking at the messages log, you find a line reflecting the empty sockets as below: Oct 12 21:36:25 Playtime kernel: audit(1160714185.460:373): avc: denied { write } for pid=29479 comm="dovecot-auth" name="auth-worker.29479" dev=dm-0 ino=692358 scontext=user_u:system_r:dovecot_auth_t:s0 tcontext=user_u:object_r:dovecot_var_run_t:s0 tclass=sock_file There is nothing in the auth log other than happy noises from Postfix about its mySQL accesses. I am unaware of any other logs that might shed some light. Troubleshooting: ============= --- I have been using standard FC5 compiled binaries sourced through YUM for all applications. To the best of my knowledge, the package that Yum pulled for Dovecot is built --with-mysql and thus should support mysql access. I found this tidbit of info in the /usr/src/redhat/SPECS/dovecot.spec document. -- I have rolled back the dovecot.conf to remove the mysql passwd/userdb configuration leaving the default PAM configuration and found that Dovecot behaves correctly and joins the party. However, since Postfix is using mySQL data, the client FQDN login user names it uses don't match up with the simple UNIX user names that Dovecot's default PAM password mechanism is supporting (thus my attempt to get them both to use the mySql database.) So from this I know that the problem appears to be basic to startup of dovecot-auth and the mysql configuration. -- I have verified the location of the dovecot-sql.conf file as configured in dovecot.conf -- I have verified that the 'connect' parameters in the dovecot-sql.conf.work from a command line and the password_query syntax from inside mysql.

In looking into this further, I see what you're getting at. There are commands in postfix/master.cf which specify different flags depending on what external delivery program is used. However, I haven't touched that and none of the entries that came with the standard master.cf file reference Dovecot, so I'm not sure if any of those entries even apply. What I changed to cause Dovecot delivery to be initiated was simply the mailbox_command in postfix/main.cf: mailbox_command = /opt/dovecot/libexec/dovecot/deliver I have been unable to determine what, if any, changes are necessary in the master.cf file to customize what parameters are sent to Dovecot deliver.

[Dovecot] you got chocolate in my peanut butter?!
by Logan Shaw 13 Oct '06

13 Oct '06

Hey everyone, Ran into something positively perplexing today. A user came to me and said that this morning when they checked their mail, they got about 120 strange new messages. Upon further inspection, it seems the "new" messages are all addressed to a certain other different user and are all 3 or 4 months old. And looking in that other user's /var/mail/(username) mailbox, I see the same messages that arrived mistakenly. And they're not in the /var/mail mailbox of the user whose desktop computer they ended up on. So it would appear that, possibly, when this user connected to the server, they got someone else's messages! Messages that, in fact, came from an account they don't even have the password to! I'm really curious if anyone has seen something like this before. We're using dovecot-1.0.beta9, and have been since mid-June. I've never seen anything happen like this before. I'm perfectly willing to upgrade to the latest release candidate, but it's hard for me to "upgrade and see if that fixes it", because it happens so rarely and it won't be easy to know empirically. So what I'm really hoping for is confirmation that this is/was a known problem, if in fact it is. Of course, I don't know that this is a dovecot bug, but I could imagine that it might be (maybe a daemon forgets to switch users after one session is closed and another is opened?), so I thought I'd ask. I did see what looked like TLS fixes and login fixes in the changelogs, so it doesn't seem out of the question that such a bug could've existed. Some more information: I checked the user's settings on their desktop computer, where the unexpected messages appear, and sure enough, there is only one POP server account configured there, and it has the correct username. What's more, I asked them what time this happened, and they said probably at 7:00am or maybe a little earlier. Looking at my dovecot logs, I see this (where 'theuser' is the user who received the messages): Sep 28 06:59:49 myhostname dovecot: pop3-login: Disconnected: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: pop3-login: Login: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: POP3(theuser): Disconnected: Logged out top=0/0, retr=0/0, del=0/9, size=130585 So, it would seem that the user did login at the time they claimed and it was at that time (or close to it) that the weird messages appeared. Also, I checked the logs for logins from the person whose messages accidentally got downloaded, and it doesn't show them logging in until several hours later. Oh, and there are no log entries for either of the two users in question before that, at least not for over 12 hours before that. The user is running Outlook 2003, with POP3 + TLS access to the mailbox. My dovecot.conf has nothing fancy in it: base_dir = /var/run/dovecot/ ssl_cert_file = /etc/mail/certs/server.crt ssl_key_file = /etc/mail/certs/server.key protocols = imap imaps pop3 pop3s disable_plaintext_auth = no login_dir = /var/run/dovecot/login syslog_facility = local0 first_valid_uid = 100 protocol imap { } protocol pop3 { pop3_lock_session = yes pop3_uidl_format = %08Xv%08Xu } auth default { mechanisms = plain user = root passdb shadow { } userdb passwd { } } The accounts are all coming out of LDAP via nsswitch (and this is all happening on Slackware 10.2), but I'm fairly sure that's irrelevant since "getent passwd", etc. all show the right stuff. Thanks for any help anyone can give... - Logan

[Dovecot] Feature req: auth_cache_relookup
by Bill Boebel 13 Oct '06

13 Oct '06

With auth_cache_size set to a value greater than zero, when our users change passwords their accounts stop working for a few minutes, because they are trying to log in with their new password, but Dovecot is comparing that against the cached old password. It would be nice if an option could be added so that if the login password does not match the cached password, the cache value is dropped and dovecot-auth queries the userDB, but only if the previous login was successful (to avoid frequent queries for bad logins). Maybe this option could be called "auth_cache_relookup" Bill

[Dovecot] default_mail_env renaming
by Timo Sirainen 13 Oct '06

13 Oct '06

I was thinking about renaming default_mail_env to something that is more understandable. I'll keep it working for backwards compatibility anyway. How about: # Location for users' mailboxes. This is the same as the old default_mail_env # setting. The default is empty, which means that Dovecot tries to find the # mailboxes automatically. This won't work if the user doesn't have any mail # yet, so you should explicitly tell Dovecot the full location. # # If you're using mbox, giving a path to INBOX file (eg. /var/mail/%u) isn't # enough. You'll also need to tell Dovecot where the other mailboxes are and # where Dovecot can place its index files. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/variables.txt for full list. Some examples: # # mail_location = maildir:/var/mail/%1u/%u/Maildir # mail_location = mbox:~/mail/:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n # # http://wiki.dovecot.org/MailLocation # #mail_location =

[Dovecot] 1.0.rc8 released

13 Oct '06

I've still over 200 mails unread in the mailing list, and important things left in TODO. This release is an improvement over rc7 anyway, hopefully I'll have time to fix the rest soon. http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz.sig * GSSAPI: Changed POP3 service name to "pop", which is what the standard says * "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" + SHA1, LDAP-MD5, PLAIN-MD5, PLAIN-MD4: The password can be now either hex or base64 encoded. The encoding is detected automatically based on the password string length. + Allow running only Dovecot master and dovecot-auth processes with protocols=none setting + deliver: -f <envelope sender> parameter can be used to set mbox From_-line's sender address + deliver: Log all mail saves and failures + Tru64 SIA passdb support. Patch by Simon L Jackson. - INBOX was listed twice in mailbox list if namespace prefix was used - INBOX-prefixed namespaces were a bit broken - kqueue: Fix 100% CPU usage - deliver: Duplicate storage was a bit broken - dictionary code was broken (ie. dict quota) - SIGHUP caused crashes sometimes

[Dovecot] 1.0rc8: another problem? Possibly 64-bit index?
by David Lee 13 Oct '06

13 Oct '06

Yesterday I gave a status report about 10.rc8 in production, which mentioned a problem about "Login process died too early..." Timo suggested a patch for logging error messages. I've applied this. Others suggested increasing "login_max_processes_count". That was already way above our likely maximum, but I've doubled it anyway. Today, I've just repeated the trial, but with one significant difference and one significant new problem. The significant difference is that today's machine is not a 32-bit i686 but a 64-bit (and faster) x86_64. The new problem is lots of occurences of: [...]: IMAP([...]): file ../../../src/lib-index/mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) [...]: child 4365 (imap) killed with signal 6 and: [...]: IMAP([...]): file ../../../../src/lib-storage/index/index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) [...]: child 15009 (imap) killed with signal 6 Naturally, I've backed off quickly. Theoretically, this problem could be attributed to any of the three changes: logging, max processes, different (64-bit) machine. I suspect it's not the "login_max_processes_count" increase. Is it a side-effect of the better logging? (That is, was it always happening but the information simply not getting logged?) Note that our index files (and mail spool (INBOX, folder) areas) are on an NFS (NetApp) shared area accessed by all three classes of our machines: o existing UW-IMAP (which doesn't use the indexes) o yesterday-dovecot (32-bit) o today-dovecot (64-bit) My sneaky suspicion is that this is a subtle 64-bit-ism, either on its own, or in some sort of interaction with an indexes created from yesterday's 32-bit client. (Yes, theoretically, I could try another test to attempt to confirm or eliminate the 32/64 difference. But these issues didn't show up under testing, but only when we began trial service; I can't experiment on the users!) -- : David Lee I.T.

[Dovecot] Received dates problem in Outlook after migration
by James Wyper 13 Oct '06

13 Oct '06

Hello everyone, I've just started using 1.0-beta3 on Ubuntu Dapper, having migrated from an mbox / UW-IMAP combination to a Maildir / Dovecot one. For some reason the mb2md tool failed to recognise some of my mbox files as valid ones, so I migrated my email by running UW-IMAP, copying my folders to local storage in Evolution, then running Dovecot instead and copying the folders back. All seems OK, except that in Outlook 98 all the emails now have the date/time of their migration, not when they were received. This isn't a problem in Thunderbird or Evolution - but my wife uses Outlook and doesn't wish to switch. I've tried using touch to change the timestamps of the mails in my inbox (in ~/Maildir/cur) but this hasn't had any effect. I've also tried deleting ~/Maildir/dovecot.index and ~/Maildir/dovecot.index.cache but this hasn't made any difference either. Something else in dovecot must be being sent to Outlook as the date / time on these emails. Can anyone suggest what it would be and how I might go about changing it (to, for example, the Received: date on the email header?). Thanks in advance, James. ___________________________________________________________ Try the all-new Yahoo! Mail.

[Dovecot] Dovecot freeze - 1.0 rc7 - FreeBSD 6.1
by Floris van den Berg 13 Oct '06

13 Oct '06

Hi, One of my customers currently experiences a dovecot freeze on random accassions. Trying to figure out what's wrong with no luck. Dovecot is running fine, up until it suddenly stops responding. The log file says: dovecot: Oct 05 10:12:26 Info: pop3-login: Disconnected: Inactivity: rip=82.217.29.*, lip=85.17.42.165 dovecot: Oct 05 10:12:29 Info: pop3-login: Disconnected: Inactivity: rip=86.87.152.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:13:17 Info: pop3-login: Disconnected: Inactivity: rip=86.88.180.*, lip=85.17.42.165 No other errors are logged. When i restart dovecot it runs fine again for some time. Sometimes it works for a few days, sometimes just a few hours. There's always a point where it freezes again. Reinstalled dovecot. Fiddled a bit with the auth_worker_max_count and auth_process_size settings. No change in behavior was observed. There's no out of the ordinary cpu or memory use. Any ideas? Floris

Dovecot adds lots of spaces after X-Keywords which could just make it look like that. If it really is a blank line, then it's most likely something else than Dovecot that changes the spaces that way.

[Dovecot] Filtering Mails - how?
by Daniel Seichter 12 Oct '06

12 Oct '06

Hello, I've got some problems about understanding, how to filter my incoming mails. I am using dovecot 1.0.beta3 (ubuntu server) and want to implement a filter, where I can filter all my incoming messages (like the ones from the dovecot ml) to special folders within the mailbox of each user (for each user a special set of filters). Is there a chance to do this in dovecot or have I to use another program? My system works like: Fetchmail fetches mails from two mailservers and deliver them to the users inbox Procmail send them to spamassassin for checking about spam Dovecot provides access to the mailbox with IMAP Hope there is an easy way like module for webmin or something else. Thank you Daniel

[Dovecot] 1.0rc8 status report
by David Lee 12 Oct '06

12 Oct '06

A quick status report on how 1.0rc8 behaved in service for a few hours with several hundred simultaneous users, at a site very new to dovecot. Oh, and a question at the end. Summary: Reasonable for a first shot but one significant problem, requiring backing off. Background: We have a long-established UW-IMAP service for a user population of about 20,000 based on a few Linux (Redhat) machines running IMAP/POP and inbound delivery. We try to ensure, but cannot guarantee, that all activity for a given user takes place within one machine. Each machine mounts the INBOX area ("/var/spool/mail"; traditional UNIX mbox) via NFS with tight NFS arguments ("noac,actimeo=0", etc.) and similarly mounts the users' folder areas which are subdirs of their home directories. (We know that Mark Crispin recommends against NFS for UW-IMAP, but we seem to have been OK.) There is also some processing: .forward->"| procmail"->folder-or-inbox Each machine typically has several hundred simultaneous IMAP connections. This has basically worked well, but the UW-IMAP loading has been heavy. The plan: In an ideal world, I would like to restructure the above. But our world is not ideal, so we have to stay with the structure. But we are looking for a transparent (user perspective) migration to dovecot. The dovecot experience: Yesterday, I quietly adjusted a DNS entry to redirect one of the live email hostnames at an additional machine in the "farm", running dovecot 1.0rc8, including deliver/LDA (and taking into account some post-rc7 dovecot changes in this area). On an earlier, smaller-scale test, one problem had been some periods of "temporary authentication failures". Increasing "login_processes_count" and "login_max_processes_count" (each by a factor of 8) seems to have fixed this, and I'm not aware of any problems in that area yesterday. It basically went well. But just over two hours hours later I had to back off, because of a significant dovecot problem, namely that dovecot crashed, almost silently. The only traces of this event in the log file seem to be: Oct 10 16:26:12 [...] dovecot: child 24525 (login) returned error 89 Oct 10 16:26:14 [...] dovecot: Login process died too early - shutting down Any thoughts? Any fixes? If the problem needs debugging (or additional data/log collection) how might that be attempted in this environment? -- : David Lee I.T.

[Dovecot] Issues with Dovecot/Pam/nss_ldap
by Ejay Hire 12 Oct '06

12 Oct '06

Hello all. I have experienced an unusual behaviour from dovecot which I believe to be related to some interaction between dovecot and nss_ldap/Pam. Centos/Postfix/mbox(es)/Openldap/dovecot. The box is using PAM with ldap, and is also running BIND, SAMBA, and DHCPD. Dovecot 1.0rc2 from source. I left dovecot at the default, to use PAM for authentication and guess the mailbox. This worked well, except during peak times, dovecot would "hang", waiting an exceptionally long time after connecting before doing authentication. The users would report this as "Send/receive stuck on 64%" or something like that. During this time, I would note a number of <defunct> dovecot processes in ps. Increasing the number of idle login proceses in the pool to ridiculously high values (30) did not affect the symptom. Restarting dovecot would immediately resolve the issue. I believe this to be related somehow to dovecot's PAM interaction, because I was able to work around it by setting dovecot to talk directly to LDAP. Googling found isolated reports of similar behaviour in the Fedora Core 3 bug list at Redhat. It's rare I can help in project as important as dovecot, so I'm willing to spend some time tracking this down. What information can I provide to help? Thanks Ejay Hire
