Fwd: [Dovecot] Very slow select() command on large mailboxes
by Sebastjan Trepca 22 Jul '05

22 Jul '05

Maildir, its easier to export and can support hardlinks. What kind of optimizations did you have in mind? What's the downside of mbox? Problem is that version 1.0 is only test release for now.

[Dovecot] configuration of user_global_uid and user_global_gid
by KATOH Yasufumi 22 Jul '05

22 Jul '05

Hi. I'm configuring LDAP auth with dovecot (cvs trunk at 14, July) as follows: /etc/dovecot/dovecot.conf: passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } /etc/dovecot/dovecot-ldap.conf: user_attrs = mail,homeDirectory,mailbox,,, user_global_uid = 10000 user_global_gid = 1000 But "user_global_uid" and "user_global_gid" definition does not work. dovecot: Jul 14 11:50:36 Error: auth(default): ldap(test(a)example.jp,127.0.0.1): ui d not in user_attrs and no default given in user_global_uid dovecot: Jul 14 11:50:36 Error: auth(default): ldap(test(a)example.jp,127.0.0.1): gi d not in user_attrs and no default given in user_global_gid How do I configure to enable "user_global_uid" and "user_global_gid"? Does my configuration have any problem? -- karma(a)jazz.email.ne.jp / KATOH Yasufumi

[Dovecot] Changing port?
by Matt Juszczak 22 Jul '05

22 Jul '05

Hi all, Trying to setup a test copy of dovecot on my box before I "really" use it. I have it installed into a test dir (/usr/local/dovecot instead of /usr/local), and I've got a config file with valid dirs, etc. Only thing is ... I can't find a way to set the port in the protocol pop3 {} section. Its documented in the "listen" directive area at the top of the config file that says its possible, but no other mention of it is ever made. How can I make my test copy listen on port 111? :) Regards, Matt

[Dovecot] Can't connect to auth server
by Todd Burroughs 22 Jul '05

22 Jul '05

I've been seeing these errors intermittently for a while now. Here's an example from the logs: dovecot: Jul 12 15:59:05 Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable The error is EAGAIN. Sometimes it will resolve itself after a few minutes and sometimes it needs to be restarted (it may fix itself, I usually get a phone call if it goes on for very long). I've looked while the problem is occuring and dovecot and dovecot-auth don't have an excessive number of file descriptors open, maybe 10 or 20. Any ideas or anything else to look at? The system is SuSE Linux 9.2 running kernel 2.6.x. We have seen some odd things happen with these systems, so it is possible that it is not dovecot. The kernel doesn't log anything unusual and other processes seem happy. Todd

[Dovecot] test76-77 dies at SIGHUP
by Johan Fredin 22 Jul '05

22 Jul '05

Hello people This is on OpenBSD/sparc64. After chickening along with 0.99 for a while, I finally upgraded to 1.0-test. I started out with test73, which worked fine. With the upgrade to test76, I lost the ability to SIGHUP dovecot when I rotated it's logfile. Dovecot would just die abruptly, not a trace in the log. I just upgraded to test77, but the problem is still there. I've put up my logfile and the last bit of a ktrace here: http://legonet.org/~griffin/tmp/dovecot/ The ktrace is partitial mostly because it contains usernames, I can edit those out and upload the hole shebang if that'll help. I'd appreciate any tips/pointers on this one! /Johan

[Dovecot] test77, yahoo & fetchmail
by Chris Spiegel 22 Jul '05

22 Jul '05

I've run into a rather narrowly scoped problem .. On test77 and test78, mails from Yahoo's webmail are seen, by fetchmail using imaps, to have a 0-length body. When fetching, it claims "0 body octets". Other mail clients (mutt, kmail) can view the messages fine. pop3s retrieval works as well. Every other email I've received so far works fine. It's just those sent by Yahoo's webmail service that have the problem. imaps retrieval does, however, work fine with test76. Let me know if there's anything I can do to help track this down. Thanks, Chris

[Dovecot] linux 2.4 vs 2.6 kernel
by vmstech 20 Jul '05

20 Jul '05

hi I read ( I think in dovecot wiki) that ext2 or ext3 fs on a 2.4 kernel can get slow due to the number of files in a directory. Does anyone know if kernel 2.6 has similar limitation? I'm not at that point now, but before the box goes live, I'm wondering if I should resolve that. Glenn

[Dovecot] Debian has moved to 1.0stable
by Jaldhar H. Vyas 20 Jul '05

20 Jul '05

Now that sarge has been released, I have as requested moved Debians' Dovecot packages to the 1.0stable branch. Most of the work was actually done by Fabio Tranchitella who is joining me as co-maintainer. The new packages should be available in sid later today. A backport to sarge will also be provided as soon as I can get around to it. Please report all problems to the Debian bug tracking system (see http://bugs.debian.org for instructions or use the reportbug package) not to me directly so that Fabio can also see. -- Jaldhar H.

Re: [Dovecot] linux 2.4 vs 2.6 kernel
by Paul Vatta 20 Jul '05

20 Jul '05

> > >> ------------------------------------------------------------------------ > We were posed with the same dilemma, but it was due to the need to stick with RHEL supplied packages (ReiserFS does not come with RHEL) that we stayed with ext3. Our old production mail server, running our in-house flavour of Linux, was based on the 2.4 kernel with ReiserFS. We load tested Dovecot with maildir under RHEL3 (2.4 kernel) using ext3 and found it was unable to standup to our requirements. In part this was due to an inordinate imap-login / pop-login processes being created and hanging around under RHEL3. Using RHEL4 (2.6 kernel), we found we were able to handle the required load - this is the configuration we went live with. Processes ended cleanly too (result of the improved schedular and how it interacted with our IBM x445 and its NUMA architecture?) and the I/O issues seemed to have been resolved - ext3 was fine. >> Subject: >> Re: [Dovecot] linux 2.4 vs 2.6 kernel >> From: >> Marc Perkel <marc(a)perkel.com> >> Date: >> Mon, 18 Jul 2005 18:33:54 -0700 >> >> CC: >> dovecot(a)dovecot.org >> >> >> >> >> Curtis Maloney wrote: >> >>> Marc Perkel wrote: >>> >>>> Actually - yes.

[Dovecot] Compiling under Fedora Core 4 - Problem
by Marc Perkel 19 Jul '05

19 Jul '05

OK - trying to migrate to dovecot and I like what I see so far, but having a hard time getting it to work. I decided to go with the 1.0 version because I need to get away from the ~/Mail namespace. I'm trying to port from a Linuxconf virtual WU-IMAP type config. So - I compiled but then decided I wanted mysql so I tried to reconfigure and now getting compile errors.

Re: [Dovecot] linux 2.4 vs 2.6 kernel
by Brian Bartholomew 19 Jul '05

19 Jul '05

I can heartily recommend reiserfs on kernel 2.4 for Intel and Sparc. My spam filtering setup currently has 27K files in a quarantine dir, and it works just fine. In a year and a half over 50 machines I've had three corrupted reiserfs filesystems, none of them on production machines, at least one of which I can blame on a bad disk. I would not be surprised to learn they were all bad disks, because the disks are five+ years old. For the last one I moved the bad dir aside where it sat peacefully for a week, and when I fsck'ed it the more aggressive mode of fsck coredumped partway through and it became unaccessable. I then restored it from the tar I had made prior. Brian

[Dovecot] IMAP: Get rid of non-existent folders below INBOX
by André Wendt 19 Jul '05

19 Jul '05

Hi, I am using Debian Sarge w/ dovecot-imapd package 0.99.14-1. Squirrelmail created three folders below INBOX, Drafts/Sent/Trash, that I already had elsewhere. Thus, I deleted them (through SqM). However, both Thunderbird and Squirrelmail still show these folders anyway. When I select them, I keep getting "Mailbox does not exist" errors. I already tried to move all .imap.index* files in .INBOX/ out of the way -- dovecot created new ones but the folders still appear. I am stuck. How can I prevent dovecot from advertising those non-existent folders? Is this an index-structure problem? I'd appreciate any suggestions. Thanks, -- André

[Dovecot] dovecot(pam_unix)[13823]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost
by Donald Gunn 18 Jul '05

18 Jul '05

I installed Dovecot on our FC3 sendmail server and get this from our Dallas office. dovecot(pam_unix)[13823]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost Only one user can get mail (pop3 or imap). All local users work fine. I ended upgoing back to UW and all works fine. What should I look for? Thanks

[Dovecot] issues/workarounds to build dovecot on OSX
by OpenMacNews 17 Jul '05

17 Jul '05

hi all, a few notes/issues re: building dovecot on OSX. first, after DL of cvs-head, % autogen.sh reports: autogen.sh: line 2: libtoolize: command not found o OSX, 'libtoolize' has been sed'd to glibtoolize. couple of ways to deal with this: (a) edit in autogen.sh aclocal --- libtoolize --force +++ glibtoolize --force automake --add-missing autoheader autoconf (b) run % autoreconf -i -f instead (c) i suppose yout can link: % ln -s /usr/bin/glibtoolize /usr/bin/libtoolize imho, too 'kludgy' ... never tried it. (d) put some sort of conditional in autogen.sh ... many options of course e.g.: HOSTTYPE=`uname` if [ "$HOSTTYPE" == "Darwin" ]; then LIBTOOLIZE=glibtoolize else LIBTOOLIZE=libtoolize fi fwiw, i'm using (b) --> % autoreconf -i -f successfully. next, dovecot's ./configure fails at the check for openssl: ... checking whether va_lists can be copied by value... yes ./configure: line 27241: syntax error near unexpected token `SSL,' ./configure: line 27241: ` PKG_CHECK_MODULES(SSL, openssl)' % within a pkg-config stanza ... as pkg-config does not exist on OSX, a couple of hacks in 'configure.in': =================================================== (EDITOR) configure.in @1032 if test "$want_openssl" = "yes" && test "$have_ssl" = "no"; then --- if pkg-config --exists openssl; then +++ if test -f openssl; then --- PKG_CHECK_MODULES(SSL, openssl) CFLAGS="$CFLAGS $SSL_CFLAGS" =================================================== , followed, of course, by another: % autoreconf -i -f take care of the problem. with changes as above, 'configure' with: ./configure \ --prefix=/usr/local/dovecot \ --exec-prefix=/usr/local/dovecot \ --bindir=/usr/local/dovecot/bin \ --sbindir=/usr/local/dovecot/sbin \ --libexecdir=/usr/local/dovecot/libexec \ --libdir=/usr/local/dovecot/lib \ --includedir=/usr/local/dovecot/include \ --sysconfdir=/var/Settings/Dovecot \ --localstatedir=/var/Process \ --mandir=/var/Documentation/man \ --datadir=/var/Data/Dovecot \ --with-ssl=openssl --with-ssldir=/usr/local \ --with-rundir=/var/Process/dovecot \ --with-moduledir=/usr/local/dovecot-modules \ --enable-shared \ --enable-static \ --enable-ipv6 \ --with-pgsql \ --disable-debug completes sueccessfully, as do: make make check make install resulting in: % ls -aR .: . .. libexec sbin ./libexec: . .. dovecot ./libexec/dovecot: . checkpassword-reply dovecot-auth imap-login pop3-login .. deliver imap pop3 rawlog ./sbin: . .. dovecot dovecotpw as, i believe, expected. now, onward! cheers, richard

[Dovecot] "dovecot virgin": 1st questions ...
by OpenMacNews 17 Jul '05

17 Jul '05

hi all, "uncle"! i've thrown up my hands with cyrus, and am looking for a 'better alternative' ... i'm brand new to dovecot (haven't even built it yet ...), and have spent the last while reading through the LIST archives here. apart from the TECHNICAL aspects, which seem _more_ than adequate/competitive, i'm most attracted by a comment abt this LIST/community: > awesome technical support with patient developer-dudes on hand which, in a nutshell, is what i seem to be missing. so, i'm preparing to "take the plunge" w/ dovecot. two preliminary questions, if i might: (1) what sort of *interest* is there here (Timo? others?) in Dovecot on OSX? i'm usually able to get most anything up-n-runnig on my OSX boxes, but i'd like to join a community where every issue-on-Mac is not simply ignored/slammed ... and there might be folks willing to work with me on issues (2) here-we-go-again with the Maildir/Mbox decision :-) what's the latest thinking/recommendation here wrt mailbox/mdir? my specifics are -- i intend to backend Dovecot with Exim ... and will run my server 'closed box' ... i.e., no file-system-related User accounts. rather, just 'virtual' spaces. i'm leaning towards Maildir's one-flat-file-per-message format, with an eventual/possible move to storage in PostgreSQL if/when Dovecot adds the capability ... thoughts? (yes, i know, y'all must've had the discussion a g'zillion times ... a pointer to a good/relevant thread is great too!) cheers, richard

[Dovecot] Authentication feature I need
by Marc Perkel 17 Jul '05

17 Jul '05

OK - here's whay I need to make it work for my Linuxconf compatible authentication system. First - a question: Will this work? I can find docs on "virtualfile. auth virtualfile { mechanisms = plain digest-md5 userdb = passwd-file /etc/vmail/passwd.%d passdb = passwd-file /etc/vmail/shadow.%d user = root } Then - since the dmain name selects the passwd file, if there were a feature to make %n be us user instead of the whole email address then I have what I need. Password files are placed in the /etc/vmail directory as follows: /etc/vmail/passwd.domain1 /etc/vmail/shadow.domain1 /etc/vmail/passwd.domain2 /etc/vmail/shadow.domain2 The password and shadow files are exactly the same format as the /etc/password and /etc/shadow files. The user name within the files would be the %n part of the email address passed to authenticate with. Basically the password file names are /etc/vmail/passwd.%d with the user withing the file being %n. marc:x:40000:12:Marc Perkel:/vhome/perkel.com/home/marc:/bin/false test:x:40001:12::/vhome/perkel.com/home/test:/bin/false dd:x:40002:12:Atia:/vhome/perkel.com/home/dd:/bin/false test2:x:40003:12::/vhome/perkel.com/home/test2:/bin/false

[Dovecot] Feature Request - Authentication Scheme - Linuxconf
by Marc Perkel 17 Jul '05

17 Jul '05

This would make my life a lot easier in migrating to Dovecot. And it should be really easy to implement. Here's how linuxconf does it: Password files are placed in the /etc/vmail directory as follows: /etc/vmail/passwd.domain1 /etc/vmail/shadow.domain1 /etc/vmail/passwd.domain2 /etc/vmail/shadow.domain2 The password and shadow files are exactly the same format as the /etc/password and /etc/shadow files. The user name within the files would be the %n part of the email address passed to authenticate with. Basically the password file names are /etc/vmail/passwd.%d with the user withing the file being %n. marc:x:40000:12:Marc Perkel:/vhome/perkel.com/home/marc:/bin/false test:x:40001:12::/vhome/perkel.com/home/test:/bin/false dd:x:40002:12:Atia:/vhome/perkel.com/home/dd:/bin/false test2:x:40003:12::/vhome/perkel.com/home/test2:/bin/false It also makes merging several servers with separate passwd/shadow files into one virtual system because all you have to do is copy their existing passwd/shadow files into the /etc/vmail directory and rename them with the domain at the end. So - wouldn't that be easy to add? Sure would make migrating easy for me. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] user_db, uid/gid and maildir
by vmstech 17 Jul '05

17 Jul '05

Im experimenting with putting all my virtual users mail under 1 directory with belonging to a system user created for the purpose. The mode on the directory (and subdirectories) is 770. I keep all my virtual users details in a postgres database. My interpretation of the wiki documentation is that if the user_db query returns a uid column and a gid column containing the numeric uid and gid of the owner of the directory, then dovecot should have no problem using mail in these folders. Is that correct? (I'm actually getting permission errors appear in the log file on the directories when I try and attach with a client, which reports "Cannot get LIST information for pattern `*' on IMAP server a.b.com unknown".) thanks Glenn

[Dovecot] Authenticaing in postgresql
by vmstech 17 Jul '05

17 Jul '05

Hi all - Im new to dovecot and actually all things email serverish. I spent last week wrestling with exim4, and this week its dovecots turn. I'm trying to connect as an imap user (from evolution) and not actually able to make a successful login. I have default_pass_scheme=PLAIN, and am using pass authentication in evolution client. Its the only one available after it queries the server for available types. I'm not getting any errors appear in either the postgres or dovecot log files (anymore :-) that is). I'm getting the exact query I'd like to see in the dovecot log file, after I entering the password in the client, but unfortunately it doesnt give me the reply. I can key this exact query in to the psql client and get the correct answer. dovecots logs don't tell me if I have success or failure. The auth_db query has only 1 column. I have no idea where to go from here - would love a hint thanks Glenn

I would merrily gdb into a coredump and stacktrace away, if a core dump were created. No such luck. I'm now logging directly to file using syslog, after having started dovecot.

[Dovecot] OS X Mail.app 2 (Tiger) + dovecot -> new mail count doubled
by Alan Schmitt 14 Jul '05

14 Jul '05

Hello, I've noticed a strange bug with Mail.app 2 (from OS X.4) and dovecot, and I'm trying to identify where it comes from. I have a bunch of mailboxes that can receive new mail (delivered by procmail) and I have Mail set up as to automatically synchronize all maiboxes. When I start up Mail, the count for new mail is doubled in every mailbox that I have not seen yet. Looking at a mailbox restores the correct count (mail is not actually duplicated, it's just the new mail counter that is wrong). Has anyone else seen this? Would this bug be from Mail.app or from dovecot? (I suspect the former.) Thanks a lot, Alan Schmitt
