[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

Hi all, I have instaled dovecot 1.0.rc10, and my configuration works fine if I get the mail with Evolution mail client, bu if I try to use outlook to get mails the authentication fail and I can't pass through the logon window. The maillog appear this message: dovecot: pop3-login: Disconnected: rip=192.168.0.22, lip=192.168.0.1 My dovecot configuration is: protocols = pop3 ssl_disable = yes mail_extra_groups = mail protocol imap { } protocol pop3 { pop3_uidl_format = %v.%u } protocol lda { postmaster_address = postmaster(a)example.com } auth_username_translation = "@." auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } any idea to solve. thanks Paul

Hi, in an installation of Dovecot I need to know when each user made his/her last POP3 connection in a maildir environment. The date of which of the index files maintained by Dovecot can I use to get this information? Thanks. Ciao, luigi -- / +--[Luigi Rosa]-- \ Left-Handers have rights too.

[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.)

.. maybe a silly one, but how does the user get notified when he is over quota? Did not find anything in the docs. Is there a general IMAP way to do this or what else ? Yours JC

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

02 Nov '06

I use Dovecot's deliver as the LDA for Postfix in a virtual user setting. My maillog reads: Oct 22 00:17:51 mail dovecot: auth(default): master in: USER 1 mark.ruys(a)in2sports.net service=deliver Oct 22 00:17:51 mail dovecot: auth-worker(default): sql(mark.ruys(a)in2sports.net): SELECT maildir AS home, 5000 AS uid, 5000 AS gid, CONCAT('dirsize:storage=', round(quota/1000)) AS quota FROM mailbox WHERE username = 'mark.ruys(a)in2sports.net' AND active = 1 Oct 22 00:17:51 mail dovecot: auth(default): master out: USER 1 mark.ruys(a)in2sports.net home=in2sports.net/mark.ruys/ uid=5000 gid=5000 quota=dirsize:storage=10240 Oct 22 00:17:51 mail deliver(mark.ruys(a)in2sports.net): msgid=<00c801c6f55e$af416fb0$8801a8c0@Moskou>: save failed to INBOX Oct 22 00:17:51 mail deliver(mark.ruys(a)in2sports.net): open(in2sports.net/mark.ruys//.temp.mail.in2sports.net.12777.5c70c02bb158bd1 a) failed: No such file or directory The reason is, I'm out of quota. I expected some kind of bounce, but the message is killed by Amavis because of a bad header: Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: 8bit Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Quota exceeded --12684/mail.in2sports.net Content-Type: message/disposition-notification Reporting-UA: mail.in2sports.net; Dovecot Mail Delivery Agent Final-Recipient: rfc822; mark.ruys(a)in2sports.net The problem is, there is no recipient (header is missing). Anyone a clue how to fix it? Thanks for some directions.

[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
