[Dovecot] imaptest10 and stalled messages
by Mike Brudenell 01 Apr '07

01 Apr '07

Greetings - I've now got as far as playing with the imaptest10 test utility to see if I can stress-test our development server. imaptest10 is built against dovecot-1.0rc28 It may just be that I'm excessively heavy handed, but when I let imaptest10 rip with the command... ./imaptest10 user=test%03d host=testserver.imap.york.ac.uk clients=50 mbox=./dovecot.mbox msgs=1000 secs=30 logout=10 ...after 15 seconds or so I started getting output along the lines of: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 10% 30% 5% 2 0 1 1 1 0 0 0 0 0 0 50/ 50 2 0 0 1 1 0 0 0 0 0 0 50/ 50 0 0 2 2 0 1 1 1 1 1 0 50/ 50 2 0 2 2 0 1 1 1 1 1 2 50/ 50 0 0 1 1 0 0 0 0 0 0 0 50/ 50 - 16. stalled for 16 secs in LOGIN - 17. stalled for 16 secs in LOGIN - 18. stalled for 16 secs in LOGIN 2 1 1 2 1 0 0 0 0 0 0 50/ 50 - 17. stalled for 17 secs in LOGIN - 18. stalled for 17 secs in LOGIN - 22. stalled for 16 secs in LOGIN - 23. stalled for 16 secs in LOGIN - 24. stalled for 16 secs in LOGIN 1 0 1 1 0 0 0 0 0 0 0 50/ 50 - 17. stalled for 18 secs in LOGIN - 18. stalled for 18 secs in LOGIN - 22. stalled for 17 secs in LOGIN - 23. stalled for 17 secs in LOGIN - 24. stalled for 17 secs in LOGIN - 28. stalled for 16 secs in LOGIN - 29. stalled for 16 secs in LOGIN - 30. stalled for 16 secs in LOGIN - 31. stalled for 16 secs in LOGIN - 32. stalled for 16 secs in LOGIN The "stalled" log lines continue until the test completes. I'm assuming it's just that I'm pushing our hardware beyond its reasonable limits: it is only an oldish development box... Sun v120 with 1 650MHz SPARC processor and 1Gbyte RAM Dovecot is using shadow password file authentication. The mail folders are in Maildirs, NFS-mounted from a NetApp filer, and each account's INBOX has around 1000 messages in it. Control and Index files are on local disk. By the end of the 30 second test run load average has climbed to around 11 I don't know how "active" the imaptest10 utility is when it's running, but do you think I should be concerned by the "stalled" messages? That is, do you think I have something configured amiss? Or is it likely just to be I'm expecting too much of our hardware? (The real system will have beefier Suns with Opteron-based CPUs, more memory, etc) With thanks, Mike B-) PS. I forgot to say: despite all this activity there's not a single error logged by Dovecot in the (admittedly short at this stage) test runs. -- The Computing Service, University of York, Heslington, York Yo10 5DD, UK Tel:+44-1904-433811 FAX:+44-1904-433740 * Unsolicited commercial e-mail is NOT welcome at this e-mail address. *

[Dovecot] locking question
by Stewart Dean 01 Apr '07

01 Apr '07

There are three applications that have their mitts on files on my mail server, which is running AIXV5.3 and UWIMAP and mbox format. The mail folders and INBOXES are native to that machine, but also are NFS exported to a login server and a mailing list server. All three machines are running the lockd daemon. Everybody wants to lock differently 1) procmail (delivering for sendmail), which seems to want to use dotlocking, fcntl and lockf locking; for whatever reasons, the compile time tests seem to disallow flock. 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: mbox_read_locks = flock mbox_write_locks = dotlock flock 3) I want to run dovecot in the same environment as I switch over, for which the locking strategy is supposed to be (according to http://wiki.dovecot.org/MboxLocking) mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl Since that same page in the wiki says. "*It's important that all software that's reading or writing to mboxes use the same locking settings.",* I had recompiled procmail so it only usedotlocking and fcntl (thus removing lockf in addition to the disallowed flock)...but now I bumped into the Migration/UW page and there looks to be a conflict. I want to be able to run dovecot (for testing) and UWIMAP (for all users/production) at the same time (but never at the same time with the same mailbox), but UWIMAP is doc'ed to use flock and Dovecot doesn't It's conceivable that the different locking strategies of UWIMAP and Dovecot don't matter because they would never be going after the same mail files (right?) but there is procmail, which has to interact with both. It appears to not use flock OK, even though the docs say it should since UWIMAP expects it, and I've disabled lockf as well. But will there be a conflict with procmail and dovecot's use of fcntl, which UWIMAP doesn't use?

[Dovecot] who owns dovecot files and dirs?
by Stewart Dean 01 Apr '07

01 Apr '07

...and what permissions should they have. I am thinking of /var/run/dovecot and the index directory. What ownership, group and permissions should they be? Are there any other files/dirs created for dovecot alone (not the mail folders and INBOXes); if so, how should they be owned and permed? I had thought they were to be owned by dovecot, but it turns out that they should not -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] 1.0rc29: Corrupted index cache file
by Jeff Rice 01 Apr '07

01 Apr '07

Hi, I have recently migrated from Courier to Dovecot, and I noticed a problem in one of my spam scripts. Here's the setup: Spam that needs to be retrained by the filter is placed in a maildir from the IMAP client. A cron job scans that maildir and if it finds a message, feeds it to the spam filter and removes it from the training maildir. Depending on whether or not the message was a spam or ham, it is either deleted or delivered to Inbox. It appears I am getting an error when the script deletes a mail message. I haven't checked if this message only occurs when a client is connected -- it's possible. Log excerpt: Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Maildir /home/vmail/XXXXXXX(a)finity.org/.Spam.Unsure sync: UID inserted in the middle of mailbox (8 > 3, file = msg.FHoB:2,) Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Disconnected: Mailbox is in inconsistent state, please relogin.

[Dovecot] convert plugin failing
by Adrian Bridgett 31 Mar '07

31 Mar '07

I'm struggling to get the convert plugin working using the Debian etch packages. When starting dovecot it was trying to create files in /.temp.hostname... convert-plugin.c looks like it has a couple of typos in it - it checks "mail" three times for NULL rather than mail, user, home. I changed this but it's getting called when these three items are set to: "maildir:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/Maildir" "dump-capability" "" I must be missing something - shouldn't the mailboxes only be converted when a user logs in? Should the conversion be skipped for the dump-capability user (whatever that is!) Thanks, Adrian -- Adrian Bridgett - adrian(a)smop.co.uk GPG key available on public key servers

[Dovecot] Version Numbering and releases
by Peter Lindgren 31 Mar '07

31 Mar '07

Hi all, Merging the two large recent threads, my recommendation is as follows: * The Release Candidates for 1.0 should be bug fixes only. * Each new Feature, or a Feature Set, goes in a separate branch. * That branch is tested by those who need/want that feature. * When testing is completed, the branch is merged into the main trunk. This way, we will have fairly well tested features/feature sets in the main trunk which people can fairly safe download and test and deploy, if their own tests succeeds. When the feature code is merged into the main trunk, the minor version is incremented by one (1.0.x --> 1.1.0). Bug fixes increment the revision (1.1.0 --> 1.1.1). Easy to follow, easy to package for package maintainers. Also, it's easy to write Readme's and other documentation on what's changed. (And for those who think that odd versions are for development (unstable), well, they will just wait until sufficient features have been added before they think it is stable... ) Timo's new features he sees for future versions, plan them for a 2.0 or a 1.1 or whatever version number, just don't call it 1.0.2rc1 :-) Another suggestion, is to create a Bugzilla (or similar) site for dovecot. That gives us all a chance to track changes and bug fixes. /Peter, building rc29 as I write this

[Dovecot] rc28 : can't set quotas with userdb + passwd file
by David Anderson 30 Mar '07

30 Mar '07

I'm using dovecot 1.0 rc28 - great software! I have a virtual hosting setup, with passdb and userdb both using a passwd file. I cannot get per-user quotas put in the relevant field of the userdb to work. They appear to be completely ignored; only the setting from /etc/dovecot.conf is applied. Can anyone confirm that this is working for them? If it is, can you post the relevant bits of your configuration, please? Many thanks. Kind regards, David

[Dovecot] Security hole #3: zlib plugin allows opening any gziped mboxes
by Timo Sirainen 30 Mar '07

30 Mar '07

zlib plugin allows opening gzipped mboxes as read-only mailboxes. However when using it, the mailbox name checks are bypassed so it's possible to open for example "../otheruser/somefile.gz". Only valid gzipped mbox files can be opened, and only if their name ends with ".gz". You can fix this by upgrading to v1.0.rc29 (available soon) or with this patch: http://dovecot.org/list/dovecot-cvs/2007-March/008488.html I don't think this matters much though. zlib plugin is rarely used, and those who do use it are probably using Dovecot with systems users (per-user UIDs), so the imap process wouldn't have access to other users' mbox files anyway. I found this problem when I was cleaning up the code in CVS HEAD.

[Dovecot] uiddir mailbox format with benchmarks
by Timo Sirainen 30 Mar '07

30 Mar '07

I cleaned up the lib-storage code a bit so that it's easier to write support for new mailbox formats. It could still use a bit of cleaning up. Anyway, I thought I'd try how easy it would be to implement Cyrus-like mail store which would consist of only Dovecot's index files and "<uid>." message files. Flags and everything else is kept only in Dovecot's index files (so it might not be the best idea to use it in production just yet). Several hours later I ended up having it working. The code contains: ~/cvs/m/dovecot-head/src/lib-storage/index/uiddir% wc *[ch] 144 329 3552 uiddir-mail.c 240 565 6206 uiddir-save.c 532 1367 13628 uiddir-storage.c 55 126 1712 uiddir-storage.h 169 404 4057 uiddir-sync.c 21 48 573 uiddir-sync.h 103 258 2762 uiddir-transaction.c 1264 3097 32490 total uiddir-storage.c is still a bit too bloaty with lots of copy&pasted code. The same with maildir and mbox: maildir: 6022 18232 165605 total mbox: 7859 23283 213686 total Benchmarks show that with small mailboxes it's a lot faster than maildir, and with larger mailboxes it's a bit faster. I also tested it against Cyrus. I found out that fetching ENVELOPE vs. specific headers gives quite a huge performance difference. Cyrus is optimized for ENVELOPE while Dovecot is optimized for specific headers. With larger mailboxes + ENVELOPE Cyrus is faster than Dovecot, while with specific headers Dovecot is always faster. Maybe I'll some day make Dovecot optimize for ENVELOPE also if it sees that client only wants to use it. BTW. Does anyone have better naming ideas than "uiddir"? I'll commit it to CVS HEAD once I'm sure about the name. :) u: Dovecot CVS HEAD + uiddir m: Dovecot CVS HEAD + Maildir c: Cyrus IMAP 2.2.13 ./imaptest list=0 seed=1 secs=60 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 23486 11822 23481 23476 33426 11659 8038 23472 11922 46952 m: 19367 9734 19367 19356 27453 9687 6287 19347 7983 38709 c: 5124 2553 5121 5105 7080 2559 1877 5104 3271 10228 ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5291 2704 5289 5278 7448 2706 1048 1061 5283 10563 m: 4162 2103 4162 4153 5977 2124 762 853 4153 8304 c: 4302 2157 4301 4289 6021 2072 806 879 4292 8584 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3211 1637 3206 3195 4639 1537 287 302 3202 6402 m: 2957 1508 2955 2944 4173 1440 279 306 2948 5894 c: 3933 1929 3933 3920 5604 2020 380 379 3923 7846 ------ ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1529 745 1529 1528 2184 819 136 162 1528 3056 c: 1579 813 1579 1578 2257 811 171 148 1578 3156 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3098 1552 3093 3085 4432 1520 293 334 3089 6173 c: 3664 1765 3659 3596 5106 1802 365 364 3614 7228 ====== FETCH BODY.PEEK[HEADER.FIELDS(from to cc subject)] instead of ENVELOPE: ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5777 2933 5777 5767 8215 2901 1133 1191 5767 11531 c: 3636 1794 3635 3623 5196 1843 682 722 3627 7254 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3869 1959 3868 3861 5452 1943 364 394 3859 7717 c: 3191 1620 3189 3184 4501 1598 315 327 3181 6362 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1912 966 1912 1910 2783 940 184 197 1911 3820 c: 1342 696 1342 1341 1888 682 109 126 1341 2682 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 4618 2320 4610 4604 6558 2266 452 455 4605 9205 c: 2960 1472 2956 2941 4134 1425 281 312 2910 5820

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by Scott Peron 30 Mar '07

30 Mar '07

Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott -- Scott Peron, Webmaster, Infolytica Corp. webmaster(a)infolytica.com Tel: (514) 849-8752 x269 Fax: (514) 849-4239 http://www.infolytica.com Place du Parc, 300 Leo-Pariseau, Suite 2222, Montreal, QC, Canada, H2X 4B3

[Dovecot] Version numbering
by Timo Sirainen 30 Mar '07

30 Mar '07

After v1.0 is released, I can finally get back to sane version numbers. But any comments on which one is better: a) Postfix-style: "1.1.UNSTABLE.YYYYMMDD" -> 1.1.0 (stable) b) Odd-even numbering: 1.1.x (unstable) -> 1.2.0 (stable) With a) style the releases could be done by simply copying a nightly snapshot to releases/ directory and announcing the changes since the last release. I'm not sure if that's good or bad.

Have the RC's released new features as well as fixed bugs? I've been hesitant to upgrade to an RC because they seem to be released so frequently and I have no idea if one is more or less stable than another. This uncertainty is a big show-stopper to upgrading. It would help if, for a given RC, we knew exactly what known issues that RC had. (Is that in the wiki?) I'd suggest that a "version" be assigned only to something that should get spread around. A nightly snapshot should get the version it was based from and a timestamp suffix of when it was extracted from CVS. (Were this Subversion, I'd append the repository revision, instead.) The snapshot is not a "version" but a convenient download from CVS. It should be exactly what you get with the same timestamp used in a checkout command. Apache's versioning scheme (posted by John Peacock) looks good to me: <http://apr.apache.org/versioning.html>

[Dovecot] Forbidding folder delete
by Kenneth Porter 30 Mar '07

30 Mar '07

Is there some way I can forbid the deleting of folders? I have a Thunderbird user who twice now has accidentally deleted a folder, forcing me to go fetch it from the nightly backup. I'd like to prevent this from happening again, and the easiest way to me is to block folder deletion. I'd rather do that "manually" from the shell than leave it available from the client GUI.

[Dovecot] Copy to sent mail timeouts
by Jeff Tucker 29 Mar '07

29 Mar '07

Hi. I'm running the dovecot IMAP that comes with Ubuntu Edgy, which is 1.0rc2. I realize this is old, but I'll ask my question in case anyone knows about this problem and how to fix it, or knows that a later version definitely fixes it. What I'm seeing is that the IMAP server works perfectly, except for occasional timeouts when the user sends an email with attachments, causing that email then to be copied to their sent mail folder. The behavior seen is that Thunderbird, for instance, will say it is copying to the sent mail and the progress goes up to 100%, but then stops and Thunderbird eventually says the action timed out. I don't see anything in any dovecot logging and the file does not appear in the sent mail. I don't have any other kind of timeout issues. I can move mails around folders, read large emails, or whatever. The problem seems worse with large emails, but some times it will copy 15 MB emails and some times it won't. I can't find that any particular email always fails. Any ideas? As a last resort, I'll build the latest rc from scratch, but I like the automatic installation, notification of security problems, etc. I get with the distro packages. Thanks Jeff

[Dovecot] chroot and raw logging
by Michal Soltys 29 Mar '07

29 Mar '07

I'm not sure if it's even intended to work in this particular case, but there's a problem when chroot is explicitely defined and rawlogging is used. Rawlog respects chroot point, without being actually chrooted. Consider configurtion as below, with two cases (dovecot.rawlog dir is of course created earlier, with appropriate uid/gid). 1) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: ktrace will show: 18206 rawlog CALL sigprocmask(0x3,0) 18206 rawlog RET sigprocmask -65793/0xfffefeff 18206 rawlog CALL lstat(0x81fbe028,0xcfbcc980) 18206 rawlog NAMI "/dovecot.rawlog" 18206 rawlog RET lstat -1 errno 2 No such file or directory 18206 rawlog CALL sigprocmask(0x1,0xffffffff) 2) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/./test::userdb_mail=maildir:~/Maildir: 1116 rawlog CALL lstat(0x85768028,0xcfbc1d20) 1116 rawlog NAMI "test/dovecot.rawlog" 1116 rawlog RET lstat -1 errno 2 No such file or directory 1116 rawlog CALL sigprocmask(0x1,0xffffffff) 1116 rawlog RET sigprocmask 0 I also noticed something else (not rawlog related). If I do a silly (blame my curiosity ;) thing like: valid_chroot_dirs: / and set chroot point as /./home/vmail/test.tld/test/ in passwd-file Dovecot will try to stat home/vmail/test.tld/test/ (and fail w/o beginning /), then chdir to /tmp, start pop3 or imap process, and recreate home/vmail/test.tld/test under /tmp. 17027 dovecot CALL chdir(0x87a4b29c) 17027 dovecot NAMI "home/vmail/test.tld/test/" 17027 dovecot RET chdir -1 errno 2 No such file or directory 17027 dovecot CALL setitimer(0,0xcfbe7020,0xcfbe7010) 17027 dovecot RET setitimer 0 17027 dovecot CALL seteuid(0) 17027 dovecot RET seteuid 0 17027 dovecot CALL chdir(0x3c001b72) 17027 dovecot NAMI "/tmp" 17027 dovecot RET chdir 0 ... 17027 dovecot CALL sigprocmask(0x3,0) 17027 dovecot RET sigprocmask -65793/0xfffefeff 17027 dovecot CALL execve(0x87a4bc38,0x87a4bc70,0x84fdb900) 17027 dovecot NAMI "/usr/local/libexec/dovecot/pop3" ... 17027 pop3 CALL mkdir(0x85f5a2b0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test//Maildir" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a2e0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test/" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a328,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a348,0x1ff) ... and so on, then it creates all the home/vmail/... dirs Configuration: openbsd 3.9, i386, dovecot 1.0-rc28 dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: dovecot.passdb: test:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

i'm running RHEL v 5 and 1.0-1.2.rc15 of dovecot and 2.3.3-2 of postfix. users can send mail to outside hosts, but can not receive them. i find no errors in the maillog -- i used a page from the redhat docs to configure postfix and dovecot so that they used the same mail directory... i think... any ideas on how to debug and/or fix this would be greatly appreciated. thanks, steve

[Dovecot] New mail not appearing consistently in Outlook 2003
by Karl von Randow 29 Mar '07

29 Mar '07

Hi all, I have continuously experienced a new mail not appearing problem in Outlook 2003 on Windows XP. Using Dovecot 0.99.14 on Debian Sarge and now in 1.0rc26 and rc27. The problem exhibits itself as: Some new mail is randomly(?) not shown in my mailbox. More new mail does appear, so it's difficult to know when a message has been missed. If I restart Outlook the missed new messages will appear as unread in the order where they should have been received in my inbox. I use secure imap. I get email through my inbox (receipts from a website we're testing, at its peak maybe 2-3 a minute) that are moved into another mailbox using a rule in Outlook. These are often the messages that are missed as above, but it often includes other email as well. The mail box format is mbox on the server. The mail delivery is by exim4 from Debian Sarge. I wondered if there was a locking problem between exim4 and dovecot? My transport in exim4 for delivering the mail is: mail_spool_home: debug_print = "T: appendfile for $local_part@$domain" driver = appendfile file = /home/vmail/$domain/$local_part/INBOX delivery_date_add envelope_to_add return_path_add group = mail mode = 0660 mode_fail_narrower = false The problem is reproducable in that I see the problem occur everyday. I am about to compile and install rc28 to see if that improves matters. I'd appreciate any help resolving the problem!

[Dovecot] Bug-report for rc28: Mailbox isn't a valid mbox file
by Erik van Oosten 29 Mar '07

29 Mar '07

Hi, When I try to open the attached mbox file I get the following warning in Thunderbird 1.5.0.10: 'The current command failed. The e-mail server responded: Mailbox isn't a valid mbox file'. I also tried this with squirrelmail, with the same result. The Dovecot version is dovecot-1.0.rc28, compiled from source. The attached mbox was correctly read from, and written to in earlier versions (either rc15 or rc22, I am not sure). The initial import was done (a long time ago) by copying a file from my Thunderbird profile directory. OS: SuSE 10.0, x86 Filesystem: ext3, (no NFS) Output of dovecot -n: ------------------------------------ # /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u auth default: passdb: driver: pam userdb: driver: passwd ------------------------------------- Can I somehow recover the data in this mbox?

[Dovecot] odd behavior with Dovecot LDA
by Steven F Siirila 29 Mar '07

29 Mar '07

Okay, to convince myself that quota handling was working okay with Dovecot 1.0-rc27 on Solaris 10, I tested sending a message to an account that was purposely over-quota. The account in question had a vacation message set up. For the first test, there was no $HOME/.imap directory at all. I received the vacation message, but the message which was supposed to be delivered locally queued in Postfix (temporary failure). For the second test, I created $HOME/.imap and $HOME/.imap/INBOX directories with the owner and group set to that of the user (just to make sure the code handled things the same). Again, I received the vacation message, but the message which was supposed to be delivered locally bounced back to me after Dovecot LDA crashed: <syst0005(a)peridot.tc.umn.edu>: Command died with status 139: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"". Command output: Segmentation Fault It appears that Dovecot LDA assumes that if .imap/FOLDERNAME exists that the index files must also exist.. I wonder what other assumptions might cause segfaults. -- Steven F.

I am a dovecot newbie and I am setting up a machine that already has dovecot installed.

Is there a command I can issue or a file I can examine to determine the release version of my installation? -- Randy

[Dovecot] transfer files from Plesk qmail to Dovecot and Postfix
by Frank Church 29 Mar '07

29 Mar '07

I have some files I want to transfer from Plesk qmail to Postfix with virtual mailboxes, MySQL, Maildir etc. I can add the accounts to the database manually as there are only a few of them. In the case of the mail folders, is it merely a matter of copying the mail files over, or are there some adjustments to be made to the files? I have noticed the thread about the Courier to Dovecot script and I wonder whether it may have a role in this process.

[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10..

By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.

Hi all, Does anyone have an idea how can I remove(delete) my virtual mail users' maildir? I have Dovecot + LDAP and I would like to do something like this: When I remove an user entry in my ldap server, it should remove my user directory information. Does anyone has this implemented? Or have an idea? I can remove users entry in my ldap server remotely, is there some way in dovecot? I'm asking this, cause I'm very familiar with Cyrus and I can do this with it.

[Dovecot] Deliverm, vpopmail, and valias
by John Peacock 28 Mar '07

28 Mar '07

I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock. One option of current vpopmail is to store all aliases in a valias table, that looks like this: +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+ where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example). I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do. Thoughts? John 1) inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue. -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] ignoring some subfolders [potential wishlist]
by Arkadiusz Miskiewicz 28 Mar '07

28 Mar '07

Hello I'm looking at migration path from my current setup (tpop3d/courier-imap) and I seem to miss one feature - ability to ignore some subfolders for pop3. tpop3d allows me to say: maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible (would be stupid to fetch own sent-mail via pop3 again 8-) In recent tpop3d cvs version I can also use regexps like maildir-ignore-folders: ^IMAP-Only.*$. Is it possible to ignore some subfolders in dovecot per protocol (like for pop3 only and not imap) ? If not then please consider this as wishlist, maybe in form of location negation like: mail_location = \ maildir:/var/mail/%Lu:!maildir:/var/mail/%Lu/.Something (which doesn't look sane) or with separate config directive like in tpop3d -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] problem with POP3 mail location when using namespaces
by Lutz Preßler 28 Mar '07

28 Mar '07

Hello, I have a problem (at least with 1.0rc28 and 1.0rc27) when using the following namespace definitions: namespace private { separator = "/" inbox = yes location = mbox:~/Mail:INBOX=/var/spool/mail/%u } namespace public { separator = / prefix = 0-LISTS/ location = mbox:/var/mail/lists:INDEX=~/.sharedMail/lists/index } namespace private { separator = "/" prefix = "0-MAILDIR-FOLDERS/" location = maildir:~/Maildir } IMAP access is working as expected, but when connecting with POP3(s), the (mostly empty in our case) ~/Maildir is used as mail location when it has been created (including index files) by IMAP access. If ~/Maildir does not exist/has been deleted again, POP3 uses /var/spool/mail/%u. This is independent of the private namespace section order and also an explicit "inbox = no" in 0-MAILDIR-FOLDERS namespace. Any idea if this is an configuration issue I don't understand yet or a bug?

[Dovecot] proxy host specified as fqdn in userdb
by Apostolos Papayanakis 28 Mar '07

28 Mar '07

Abstract from http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy > > host=s: The destination server's *IP address*. This field is required. > Note that currently it's required to use an IP address since no DNS > resolving is done. > Hello Timo, Here goes one more item for the v2.0 wishlist: Will it become possible to do dovecot imap proxying based on a "host" userdb attribute that is an FQDN (instead of a numeric IP as it is now)? It would simplify things for large smtp clusters that already do LDAP mail routing, based on per user "mailHost" attribute containg mail server FQDNs (according to "IETF Internet Draft LDAP Schema for Intranet Mail Routing", http://www.sendmail.org/m4/laser.txt) It is kinda redundunt to keep an extra LDAP attribute for "host" that contains essentially the same information as "mailHost" attribute, but in numeric form. I know the proposed change is not that important for many people, so don't really bother unless it is trivial to implement. apap

[Dovecot] rc2x seems to break Pegasus Mail
by Rick Romero 28 Mar '07

28 Mar '07

Hi guys, I upgraded from rc7 to rc24 a couple weeks ago, and noticed today that Pegasus Mail's IMAP no longer connects. So I put rc27 in, and it worked, but only for a little while... I'm not sure what the problem might be, the logs look fine, and I can still use Horde and Evolution without a problem. Pegasus Mail's error is unfortunately not helpful. Restarting rc27 didn't 'bring it back' for Pegasus.

[Dovecot] rc29 and documentation changes
by Timo Sirainen 28 Mar '07

28 Mar '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Any comments about the doc/wiki/ contents? doc/documentation.txt? dovecot-example.conf's doc/wiki/ pointers? ./autogen.sh now updates the wiki from http://www.dovecot.org/tmp/wiki-export.tar.gz (updated each night) if doc/wiki/Authentication.txt doesn't exist. I guess I'll release rc29 tomorrow. The current changes are: + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes

[Dovecot] MANAGESIEVE patch v3 for dovecot 1.0.rc28
by Stephan Bosch 28 Mar '07

28 Mar '07

Hello dovecot users, I have updated the MANAGESIEVE patch to apply and compile against dovecot 1.0.rc28. Not much has changed with respect to the functionality of the previous version however: ChangeLog vs v2 - Updated source to compile with dovecot 1.0.rc28, tested with rc27 (debian package) - Daemon now uses the same location for .dovecot.sieve as dovecot-lda This is typically ~/.dovecot.sieve. - If .dovecot.sieve is a regular file, it is now moved into the script storage as dovecot.orig.sieve, preventing deletion of (important) active scripts upon managesieve installation. Otherwise, it would simply be replaced by a symlink to the new active script. - Changed error handling to yield a BYE message when the managesieve daemon exits unexpectedly (upon login) before any commands are entered. Horde-ingo would wait indefinitely for a response. This patch still includes (yet another) instance of the CMU Sieve source, as explained in my previous mail (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v3.diff.gz Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] gssapi auth issue...
by Dan Price 28 Mar '07

28 Mar '07

Hi all-- been away from the list for a few weeks so forgive me if this problem has been reported-- with the help of some of our Kerberos engineers, we tracked down why we can't authenticate our Solaris kerberos clients to Dovecot. Here's the deal: Our IT organization issued us kerberos tickets of the form imap(a)foobar.sfbay.sun.com Which I presume is their standard-- and probably not negotiable. However, the hostname of the machine is: "foobar", not foobar.sfbay.sun.com (as reported by gethostname(3c)). So when dovecot does this: mech-gssapi.c: principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); ---> str_append(principal_name, my_hostname); We wind up asking kerberos to look for a ticket for imap@foobar, instead of imap(a)foobar.sfbay.sun.com. Obviously we can patch the source, but I was wondering if we could have a gssapi_hostname setting in the config file? Or perhaps we could have a knob letting us globally override my_hostname? Although I don't know what side effects that could have. We have some new cores I also need to report-- I'll get on that. Thanks in advance, -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Custom Mail Directory for some users
by Patrick Kranz 27 Mar '07

27 Mar '07

Hi list, I'm new on this mailing list and I'm kind of stucked at the moment. I managed to get Postfix and Dovecot working together with Amavis, OpenLDAP und SASL on Ubuntu Linux Release "Dapper Drake". The Dovecot version shipped with Dapper is 1.0-beta3 (at least, that's what the package database tells me), I also tried this with a Debian Backport of version 1.0-rc15. And here is my problem: A customer of mine needs usernames different from the mail address for his third party software to work. In other words, I need the ability to login with the username foo to get access to the mailbox bar(a)example.com. So I tried to override the mail_location property for this user with a separate mailDirectory attribute in my LDAP tree. Speaking in dovecot.conf words: mail_location = maildir:/var/spool/dovecot/mail/%d/%n auth default { machanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb static { args = uid=vmail gid=vmail user = dovecot } and dovecot-ldap.conf: hosts = localhost dn = cn=admin,dc=ekits,dc=de dnpass = secret auth_bind = yes ldap_version = 3 base = ou=mailsystem,dc=ekits,dc=de scope = subtree user_attrs = mailDirectory=mail user_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) user_global_uid = vmail user_global_gid = vmail a typical ldap entry looks something like this: dn: cn=Patrick Kranz,o=EK IT-Solutions,ou=mailsystem,dc=ekits,dc=de ekitsMailDestination: patrick(a)ekits.de objectClass: ekitsMailAccount objectClass: top cn: Patrick Kranz structuralObjectClass: ekitsMailAccount entryUUID: b4ebb9e8-6d8d-102b-9dc9-9edb870845a4 creatorsName: cn=admin,dc=ekits,dc=de createTimestamp: 20070323132526Z userPassword:: YVBhc3M= mailDirectory: maildir:/var/spool/dovecot/mail/ekits.de/blubb uid: patrick As far as I can interpret the log of slapd, dovecot doesn't even ask for the attribute "mailDirectory". I also tried this with userdb prefetch. With this it did actually ask for the attribute but it still had no effect. With this configuration dovecot creates the directory /var/spool/spool/dovecot/mail/patrick if I login with the uid patrick but I wanted access to /var/spool/dovecot/mail/ekits.de/blubb If anybody has any clue what I did wrong or if I have a conceptional misunderstanding, I would appreciate every help. Thanks in advance. Greetings, Patrick

[Dovecot] recent master-settings.c and main.c changes breaks dovecot on my system
by Daniel 27 Mar '07

27 Mar '07

Hi! Compiled the latest cvs today, and noticed the changes in src/master/main.c and master-settings.c. With the versions 1.80.2.19 and 1.125.2.28 (respectively) I can not start dovecot, because it says: Fatal: dup2(stdin) failed: Bad file descriptor Error: imap dump-capability process returned 89 After reverting the patch: http://www.dovecot.org/list/dovecot-cvs/2007-March/008371.html everything is back to normal. My system is OpenBSD 4.0 and dovecot is recent cvs. Daniel

[Dovecot] Coredump in dovecot-auth on gss auth
by Dan Price 27 Mar '07

27 Mar '07

I've enabled the GSS code in dovecot, but our Kerberos nerds are complaining that it doesn't work :) I probably have the thing totally misconfigured (so don't worry about that part for now), but I do have a crash: Info: imap-login: Disconnected: rip=XXX.YYY.229.8, lip= XXX.YYY.17.59, TLS handshake Error: auth(default): gssapi(?,XXX.YYY.229.8): While acquiring service credentials: No credentials were supplied, or the credentials were unavailable or inaccessible Error: auth(default): gssapi(?,XXX.YYY.229.8): While acquiring service credentials: No principal in keytab matches desired name Info: imap-login: Disconnected: method=GSSAPI, rip=129.146.229.8, lip=XXX.YYY.17.59 Error: child 188558 (auth) killed with signal 11 Info: imap-login: Disconnected: method=PLAIN, rip=129.146.229.8, lip=XXX.YYY.17.59 The dovecot auth process SIGSEGV's and dies at login time (I think).

[Dovecot] Sync of read message status between squirrelmail and outlook express
by Mohd Ikhwan Abdullah 27 Mar '07

27 Mar '07

Hi, We have a Linux email server running CentOS 4.4. I have a scenario here. The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days. 1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express. 2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'. Any suggestions is very much appreciated. Thanks in advance.

System error: No such file or directory Error: imap dump-capability process returned 89 When i check the /usr/local/lib/dovecot/imap/lib10_quota_plugin.so i see that it is a link which is pointing /usr/local/lib/dovecot/lib10_quota_plugin.so .
