[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.

[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.)

[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] 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. }

[Dovecot] FC4 and Dovecot 1.0 not displaying all migrated mailboxes
by Lovell Mcilwain 02 Nov '06

02 Nov '06

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

[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

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? In our environment )we use: /opt/XXX Optional software XXX /etc/opt/XXX Configuration for optional software XXX /var/opt/XXX Variable data for optional software XXX (Which makes for easier upgrades) -- Steven F.

[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

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

The NFS clients w/Dovecot are currently running Linux 2.6.16 with Trond Myklebust's Linux-2.6.16-NFS_ALL.dif applied (see http://client.linux-nfs.org/) This combo has been stable for months. And yes, we use fcntl locking, and mount noac,actimeo=0. JG

[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?
by Perry 31 Oct '06

31 Oct '06

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??? Thanks much for all comments and direction. ____________________________________________________________________________________ Cheap Talk? Check out Yahoo!

What have other people used? > Do we have other options? I recommend a pair of NetApp filers (e.g. 2 x 3020c) exporting NFS from shared disk shelves in their high-availability mode. This is a hybrid of the two options, except a) it's a fully supported and stable NetApp configuration, b) they're sharing disk storage, c) you're not hog-tied to GFS, d) it's the best NFS implementation in the world (you can even trust the fcntl locking), e) it's really fast, f) NetApp's onboard snapshots and other funky software bits will make you wonder how you lived without them, g) the HA actually works. I have a six-digit userbase with mailboxes in this configuration. JG

[Dovecot] auth both system and virtual users

[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
