[Dovecot] Fwd: Weird problem opening mbox in beta1/2
by Chris Wakelin 27 Jan '06

27 Jan '06

Hmm, this is peculiar! This mailbox has been unchanged on my test server since September. I've been using it to test each new version of Dovecot just after I've compiled it. When beta1 was released, I opened this mbox with no problems. However, when I upgraded to beta2, I got "file size unexpectedly shrinked in mbox file /export/mail/a/24/vis99003/INBOX (16895967 vs 16899267)". Reverting to beta1, it also failed with the same error! I've deleted indexes, restored the mbox from a backup made in October (no changes) and I still get the error. It *does* open OK in 1.0-stable. I've put it through mboxcrypt.pl, deleted the UW-IMAP pseudo-message (which wasn't converted properly by mboxcrypt) and it still fails to open with a similar error, so I've sent it to Timo (gzipped, of course!) I've e-mailed this to the list minus the attachment as sending unsolicited 1MB attachments is unfriendly! However, if anybody wants to look at it, please let me know. Best Wishes, Chris P.S. The past participle of "shrink" is "shrunk" not "shrinked" - it's yet another irregular English verb :) -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094 -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094

[Dovecot] Hang in 1.0.alpha4
by Mark Plaksin 26 Jan '06

26 Jan '06

My IMAP client hangs intermittently. When it does, Dovecot has prematurely stopped sending a response and entered the poll loop. My client is waiting for more data and Dovecot is waiting for an IMAP command. This problem seems to occur when I connect to the dovecot process over the network and when I run the imap binary directly via an SSH tunnel. Below is truss output from the imap process for one of the hangs. It is responding to a FETCH, gets EAGAIN, and then seems to give up sending the rest of the message and enters the poll loop. Below that is the log from my IMAP client to show its side of the story. Nothing shows up in the normal Dovecot log. I haven't caught it in the act recently when running with rawlog. But rawlog output from before I was running with truss shows that Dovecot does not think it has finished sending its response. truss output: 12951: stat64("/home/happy/Mail/banner-ss", 0xFFBFF200) = 0 12951: fstat64(12, 0xFFBFF388) = 0 12951: stat64("/home/happy/Mail/.imap/banner-ss/dovecot.index", 0xFFBFF2F0) = 0 12951: fstat64(18, 0xFFBFF388) = 0 12951: pread64(18, "\n F r o m b e v e r l".., 4096, 1592560) = 4096 12951: pread64(18, " S u n G a r d * S C".., 4094, 1596656) = 4094 12951: pread64(18, " M i c r o s o f t S a".., 4094, 1600750) = 4094 12951: pread64(18, " r g a r e t . d i l l a".., 4094, 1604844) = 3720 12951: pread64(18, 0x0025EEA2, 374, 1608564) = 0 12951: pread64(18, 0x0025EEA2, 374, 1608564) = 0 12951: pread64(18, " R e t u r n - P a t h :".., 4096, 1592616) = 4096 12951: write(1, " * 2 5 0 F E T C H ".., 4073) = 4073 12951: pread64(18, " a l v e r n , P A ".., 4095, 1596712) = 4095 12951: write(1, "\n W i l l i a m B .

[Dovecot] dovecot 1.0alpha5 not deleting messages from mbox
by Andrew Mendelsohn 26 Jan '06

26 Jan '06

Hi, I have had some problem with duplicate emails using dovecot1.0alpha5using the prebuilt testing binaries on a debian stable/testing 3.1system. I am running both pop3d and imap, but all users are just usingpop3d. I am using mbox format. Users are using Thunderbird 1.5 to access emails. Dotlocks are used,postfix is the email agent. Note that dovecot/[postfix are running in avserver. In debugging the dovecot log, it seems to me that dovecot thinks thatit is deleting the messages, but actually nothing is happening. here is a log of a user logging in and what happens after logging out: dovecot: 2006-01-20 21:41:04 Info: pop3-login: Login:user=<user2(a)example.org>, method=PLAIN, rip=10.8.0.6,lip=192.168.99.5, TLS dovecot: 2006-01-20 21:41:04 Error: pop3(user2(a)example.org): mbox sync:Expunged message reappeared in mailbox /home/vmail/user2(a)example.org(UID 5668 < 5691, seq=2, idx_msgs=0) dovecot: 2006-01-20 21:45:33 Info: pop3(user2(a)example.org): Logout.top=0/0, retr=20/ del=20/20, size=29362389 a quick check show that mbox size has not been changed -- none of the20/20 files have been deleted, even though dovecot states del=20/20 ! Mboxes grow quite large, sometime the problem resolves itself. Interestingly, if I stop dovecot and restart it, on the next access to pop3 all of the messages are deleted correctly and the mboxreturns to the default size. Any ideas?

[Dovecot] Dovecot using static uid gid
by Alexandru Ionescu 26 Jan '06

26 Jan '06

Hi All I have postfix deliver the mail in virtual maildirs using the UID of user dovecot. I authenticate users trying to access their mailboxes via IMAP through winbind. The authentication is successfull but dovecot logs imap(username): Date "Error: openidir (vmail/domain/username) failed: Permission denied. I tried to insert in dovecot.conf: static uid=97 gid=97 home=/vmail/domain but I get a report that parameters are missing. Does anybody know the the exact syntax for the static directive? Alexandru

[Dovecot] Making dovecot and postfix play together
by Anne Wilson 26 Jan '06

26 Jan '06

I am encountering 'transport problems' in postfix, and I can't tie them down. I'm beginning to wonder whether I have conflicting settings in the various parts of the mail server. I have been advised separately by a number of people, so it is entirely possible. I am, therefore, attempting to check every detail of my setup. I was advised to put 'MAIL=/home/$USER/MailDir:INBOX=/var/spool/mail/$USER' into /etc/profile 'because that's the way that dovecot likes it'. Is this correct? I'm using 0.99.14 on Fedora Core 4. Dovecot does appear to be working correctly. I can drag messages to the mailboxes. The problem appears to be in postfix. Fetchmail can download the messages, but they are sticking in postfix's queue. I'm still working on that, but would like confirmation that I was right to follow the advice given above. Anne

[Dovecot] Problem with folders, dovecot-0.99.13-3.FC3 and Eudora 7.0.1
by Davide Bolcioni 25 Jan '06

25 Jan '06

Greetings, the Eudora client is attempting to create a subfolder of an existing folder, using the "Make it a folder option" which creates a directory under /home/<user>/mail/<a few paths>. Eudora is seemingly stuck in attempting to create the directory, but there is nothing under /var/log which seems useful in diagnosing the problem. Thank you for your consideration, Davide Bolcioni -- There is no place like /home.

[Dovecot] Locking strategy?
by Gerhard Wiesinger 25 Jan '06

25 Jan '06

Hello! I run the following environment: UW imapd pine sendmail procmail mbox format I migrated from UW imapd to dovecot. It is pretty faster than UW imapd. To ensure a compatible environment I did the following configuration changes in /etc/dovecot.conf: protocols = imaps default_mail_env = mbox:~:INBOX=/var/mail/%u mail_full_filesystem_access = yes mbox_read_locks = fcntl mbox_write_locks = fcntl But I don't think that locking works well. In pine I get the following error messages: Unexpected changes to folder (try restarting) Also when I delete a file in the imap inbox I can't see that immediatly in pine (even when I restart pine the message is still there with a "Deleted" flag. With UW imapd locking worked perfectly but performance was very bad. What is the best configuration in a dovecot/pine/sendmail/procmail/mbox format environment. Thank you for the answer. Ciao, Gerhard

Hi darix, I'm reading it, but it says: "Software quotas Dovecot 1.0 supports quota using a quota plugin. It's currently discussed in Dovecot LDA page and it supports only very simple quota calculation which is suitable only for mboxes. Maildir++ quota support will come later." And in http://www.dovecot.org/patches/1.0/ there's the patch only, the link http://www.dovecot.org/patches/1.0/quota.tar.gz is broken. The page http://wiki.dovecot.org/LDA#head-de783575628d0e78c0e594931f173493fd8257d0 doesn't state if the plugin works for Maildir++ quotas (which is what I need). Thanks for your answer, Rodolfo.

[Dovecot] Date recieve vs date sent

Hi All, I have migrated a client from what I think was UW-IMAPD to Dovecot, using the tool imapsync (http://www.linux-france.org/prj/imapsync/) The client is using Outlook and Outlook Express as their mail client and now all of their emails have the date 20/01/2006 in the folder view. When the email is viewed directly, the date is the correct date for the email. I was wondering if any one has any suggestions on how to make the received date the same as the sent date, so that people can used their Inboxes effectively?

Yay. It works. SSL regenerated statement is gone. I was using alpha and upgraded to b1, b2 afterward. login directory is root:dovecot and when you create a brand new ssl-parameters.dat in freebsd, it inherited the gid (87) from the directory.

[Dovecot] Thanks
by ohp＠pyrenet.fr 22 Jan '06

22 Jan '06

Many thanks for helping me solving my problems After a few conf tweakings, dovecot works so well that I may put it on prod tomorrow. Many thanks to Timo!!! A few questions though: I had to raise the number of auth_process to 10 to avoid tons of messages "can't connect to socket 'default' is that ok? After tweaking my postgresql database to authenticate virtual users I notices that SQL userdb MUST have home AND mbox file. Not wanting virtual users to have anything but INBOX, I've set home dir in query to /tmp/%u. is that ok too? Best regards to all and many thanks again. -- Olivier PRENANT Tel: +33-5-61-50-97-00 (Work) 15, Chemin des Monges +33-5-61-50-97-01 (Fax) 31190 AUTERIVE +33-6-07-63-80-64 (GSM) FRANCE Email: ohp(a)pyrenet.fr ------------------------------------------------------------------------------ Make your life a dream, make your dream a reality.

Looking at the code, it should always complain in every possible situation where something might go wrong. So, first it should be figured out if the problem is in dovecot-auth or imap-login. Try adding some debugging first: diff -u -r1.16 auth-server-connection.c --- src/lib-auth/auth-server-connection.c 14 Jan 2006 18:47:23 -0000 1.16 +++ src/lib-auth/auth-server-connection.c 22 Jan 2006 13:08:19 -0000 @@ -164,6 +164,8 @@ conn->refcount++; while ((line = i_stream_next_line(conn->input)) != NULL) { + i_info("auth server: %s", line); + if (strncmp(line, "OK\t", 3) == 0) ret = auth_client_input_ok(conn, line + 3); else if (strncmp(line, "CONT\t", 5) == 0) It should be sending a MECH line with PLAIN parameter.

[Dovecot] dovecot-lda and vpopmail
by John Peacock 22 Jan '06

22 Jan '06

I'm setting up a new box with Dovecot 1.0 beta1 and vpopmail. Normal operations works like a charm, i.e. vpopmail virtual can log in sucessfully using TLS. However, when trying to test dovecot-lda out of CVS, it is not locating the user: > *** Starting dovecot-imapd service... > dovecot: Info: Dovecot v1.0.beta1 starting up > dovecot: Info: auth(default): master in: USER 1 postmaster(a)example.com service=deliver > dovecot: Info: auth(default): master out: USER 1 postmaster uid=89 gid=89 home=/home/vpopmail/domains/example.com/postmaster > dovecot: Error: auth(default): except that the "master out" line *has* the correct information, though I don't know what that "Error" line is trying to tell me. However, I am getting the mail bounced back with: > deliver: Fatal: mail setting not given which is this error in the src/deliver.c:607 /* MAIL comes from userdb, DEFAULT_MAIL_ENV from dovecot.conf */ mail_env = getenv("MAIL"); if (mail_env == NULL) mail_env = getenv("DEFAULT_MAIL_ENV"); if (mail_env == NULL) i_fatal_status(EX_CONFIG, "mail setting not given"); which would certainly suggest that the userdb access failed in deliver (though the log would see to seem to suggest otherwise). I even tried setting the DEFAULT_MAIL_ENV in dovecot.conf, but that didn't work either. Anyone have any ideas about what I am missing?

[Dovecot] 1.0 beta1 released
by Timo Sirainen 22 Jan '06

22 Jan '06

As promised, here it is finally. v1.0 is getting nearer and I want people to start looking at Dovecot's sources. Getting some more help with development would be nice, but I'd also like to hear if there are any hidden bugs in the code. So, one week from now I'll start offering 1000 EUR for the first person to point out a remotely exploitable security hole in Dovecot. See http://dovecot.org/security.html for more information. Changes since 1.0alpha5: UPGRADE WARNING: Unlike earlier Dovecot versions, 1.0 beta1 now requires Diffie-Hellman parameters to have been generated before SSL/TLS is used. These are generated when Dovecot is started for the first time and it may take several minutes. During this time SSL/TLS connections aren't working. (I decided to leave it this way at least for now. I don't think any new Dovecot admins will try to log in with SSL within the first 5 minutes of the installation?) Features: - DSA SSL connections provide now forward secrecy (which causes the DH parameter issue mentioned above) - Support for password protected SSL private keys - LDAP: Added authentication bind support. Patch by J.M. Maurer - LDAP: Added fast authentication binding. Patch by Geff <boing(a)boing.com> - PAM: Changed -session parameter to session=yes - kqueue support. Patch by Vaclav Haisman - dbox updates. Kind of works now, but not recommended for more than testing yet. There still are known bugs. - maildir_copy_with_hardlinks=yes works again - Sometimes Dovecot kept telling about keyword changes over and over again even if there weren't any. - Beginnings of fallbacking to in-memory indexes when write fails with "out of disk space" error. Not perfect yet, but helps in some cases. - When IDLEing, send a small notification every 2 minutes so that NATs/firewalls don't close the connection. - Added gdbhelper binary to help debugging Performance improvements: - Don't fdatasync() cache file. Not that important and gives better performance. - mmap_disable=yes mode doesn't keep rewriting index file now constantly, so it uses much less disk I/O. - Some other minor index file improvements Bugfixes: - UID STORE command wasn't returning UIDs in replies - Fixes for various problems with IDLE command. - THREAD command crashed if no search matches were found - Some fixes to handling LIST command with namespaces. Helps Pine. - Fixed a situation in mbox when it could get the process to infinite loop - Fixed one mbox assert crash - Use long line wrapping for X-IMAPbase, X-IMAP and X-Keywords headers for UW-IMAP compatibility - dovecot --exec-mail wasn't cleaning existing environment variables properly

Hi, http://plonk.de/sw/dovecot/dovecot.sqlite.4.diff It uses sqlite3 and is not heavily tested, but it works quite fine here. Have fun!
