[Dovecot] Bug Report in Connection with Expire Plugin
by Jörg Leis 08 Jan '09

08 Jan '09

If the expire plugin is enabled and a new message (not in trash) is deleted via IMAP in Mozilla Thunderbird (only tested in this client), it will indefinately copy the message into the folder. Dovecot, meanwhile, occupies itself with this: root@server:~# cat /var/log/dovecot.log [...] dovecot: 2008-12-26 09:21% Error: child 6132 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6133 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6134 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6135 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6136 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6138 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6139 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6140 (imap) killed with signal 11 dovecot: 2008-12-26 09:21% Error: child 6142 (imap) killed with signal 11 [...] root@server:~# cat /var/log/dovecot.info [...] dovecot: 2008-12-26 09:21% Info: imap-login: Login: user=<admin(a)bildig.ch>, method=CRAM-MD5, rip=84.75.159.19, lip=92.42.190.87, TLS dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib10_quota_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib11_imap_quota_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib20_expire_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Effective uid=5000, gid=5000, home=/home/vmail/Maildirs/bildig.ch/admin dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota root: name=User Quota backend=maildir args= dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota rule: root=User Quota mailbox=* bytes=524288000 (0%) messages=0 (0%) dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota rule: root=User Quota mailbox=Trash bytes=52428800 (0%) messages=0 (0%) dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota warning: bytes=498073600 (95%) messages=0 (0%) command=/usr/local/bin/mail-quota-warning.sh 95 dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota warning: bytes=419430400 (80%) messages=0 (0%) command=/usr/local/bin/mail-quota-warning.sh 80 dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): maildir: data=/home/vmail/Maildirs/bildig.ch/admin dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): maildir++: root=/home/vmail/Maildirs/bildig.ch/admin, index=, control=, inbox=/home/vmail/Maildirs/bildig.ch/admin dovecot: 2008-12-26 09:21% Info: imap-login: Login: user=<admin(a)bildig.ch>, method=CRAM-MD5, rip=84.75.159.19, lip=92.42.190.87, TLS dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib10_quota_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib11_imap_quota_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Module loaded: /usr/lib/dovecot/modules/imap/lib20_expire_plugin.so dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Effective uid=5000, gid=5000, home=/home/vmail/Maildirs/bildig.ch/admin dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota root: name=User Quota backend=maildir args= dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota rule: root=User Quota mailbox=* bytes=524288000 (0%) messages=0 (0%) dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota rule: root=User Quota mailbox=Trash bytes=52428800 (0%) messages=0 (0%) dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota warning: bytes=498073600 (95%) messages=0 (0%) command=/usr/local/bin/mail-quota-warning.sh 95 dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): Quota warning: bytes=419430400 (80%) messages=0 (0%) command=/usr/local/bin/mail-quota-warning.sh 80 dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): maildir: data=/home/vmail/Maildirs/bildig.ch/admin dovecot: 2008-12-26 09:21% Info: IMAP(admin(a)bildig.ch): maildir++: root=/home/vmail/Maildirs/bildig.ch/admin, index=, control=, inbox=/home/vmail/Maildirs/bildig.ch/admin [...] When the expire plugin is disabled no error occurs.

[Dovecot] Apple patches 1-5
by Mike Abbott 08 Jan '09

08 Jan '09

Here are the first few simple patches from Apple, based on dovecot-1.1.7. The comments with "APPLE" in them helped us merge in your new releases; feel free to remove them. Please let me know if you want subsequent patches in a different format, or if you have any questions. Patch #1. Some versions of Mac OS X have buggy CMSG_* macros. Patch #2. Don't set "<username>=1" in the environment. Patch #3. Some versions of Mac OS X return near-duplicate kevents. Patch #4. Null renames are actually pretty slow on HFS (Apple's file system), so avoid them. Patch #5. Required by Apple's lawyers.

[Dovecot] Apple patches 6-8
by Mike Abbott 08 Jan '09

08 Jan '09

Here are a few more patches. Still keeping it easy for now. Again the basis for these patches is dovecot-1.1.7. Patch #6. Solve a cross-compilation endianness issue. Currently, Dovecot assumes that the endianness of the build system is the same as the endianness of the runtime system. This is not necessarily true. We ran into this while compiling for i386 on a ppc machine. The patch switches to using gcc's __BIG_ENDIAN__ macro; see the comment in the patch to configure.in. It also removes the related and unused MAIL_INDEX_COMPAT_FLAGS parameter. This patch may be applicable to other build environments with a little tweaking. Patch #7. Replace all occurrences of "hash_create" and "hash_destroy" with "hash_table_create" and "hash_table_destroy" respectively. The symbols hash_create and hash_destroy conflict with symbols defined in <strhash.h> and libc. This showed up when loading dovecot's quota plugin (one of our future patches will add a hash table to it; stay tuned). The wrong hash_create was called which caused a crash at the first hash_insert. Apparently this is only a problem in loaded dynamic libraries and not linked-in ones. Patch #8. Back off after auth failures to deter abusers. Stalls 5 seconds per failed attempt. PS -- Please forgive me if I make a mistake at some point while splitting these patches out from our source tree. They're all mingled together on my end and it's sometimes tricky to extract just the right changes for each patch. If anything seems fishy just let me know and I'll take another look. Thanks.

[Dovecot] ManageSieve woes
by Rodti MacLeary 08 Jan '09

08 Jan '09

Hi everyone, New to the list, and fairly confident that this issue is purely down to my own idiocy, so please go easy on me! I've been running Dovecot 1.0.13 on Debian (via Aptitude package) for some time, and have been delighted with it. For a while I've toyed with the idea of using ManageSieve as there's a nice plugin for Roundcube, so I'm trying to follow the how-to at http://wiki.dovecot.org/ManageSieve. First of all I've downloaded the Dovecot 1.1.7 source and compiled it myself. I've patched it using the appropriate ManageSieve 1.1.7 diff file referenced in the how-to, and it all appears to be running fine. The next step is to compile the ManageSieve 0.10.4 source itself. I've extracted the tarball and attempted ./configure, but it's failing with the following errors: ./configure: line 19826: cd: ../dovecot: No such file or directory ./configure: line 19829: cd: ../dovecot-sieve-1.1: No such file or directory dovecot-config not found from /home/user/dovecot-1.1-managesieve-0.10.4, use --with-dovecot=PATH to give path to compiled Dovecot sources or to a directory with the installed dovecot-config file. configure: error: dovecot-config not found I'm not entirely sure what I'm supposed to be pointing --with-dovecot to here. I've tried the Dovecot 1.1.7 source, and /etc/dovecot. Any help greatly appreciated! Rodti

[Dovecot] Checking for strtoumax and strtoimax
by J Springer 08 Jan '09

08 Jan '09

Tru64 5.1b PK6 : dovecot 1.1.7 : cc Configuration checks for strtoumax and strtoimax are positive but both are unresolved during compilation. strtoq and strtouq checks are negative. I can modify compat.c to use "unsigned long ret = 0;" in place of strtoumax (does this break anything?) and/but I would like to know how to handle strtoimax. Thanks in advance.

[Dovecot] allow_nets overridden by cache
by Guy 08 Jan '09

08 Jan '09

Hi, I've just started trying allow_nets on one of my servers. I have auth_debug and auth_verbose both enabled and the output is as follows: Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 127.0.0.1/8 Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 10.0.7.176/28 Oct 28 13:05:48 mink dovecot: auth-worker(default): passdb(user(a)domain.net,x.x.x.x): allow_nets check failed: IP not in allowed networks Oct 28 13:05:50 mink dovecot: auth(default): client out: FAIL 1265 user=username(a)aluminati.net Oct 28 13:05:50 mink dovecot: auth(default): cache(user(a)domain.net,x.x.x.x): hit: <hidden> user=user(a)domain.net Oct 28 13:05:50 mink dovecot: auth(default): client out: OK 1266 user=user(a)domain.net auth_cache_ttl is set to 300. If I set it to 1 then the allow_nets successfully rejects. Once I set it back up to 300 the cache overrides the result from the allow_nets check and let's the account log in even though the allow_nets check fails. I've tried waiting for longer than the 300 seconds and then logged in again, but I still get the same result as above. Is there a gotcha that I'm unaware of or have I done something stupid (which seems the most likely :P)? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Setting IMAP keywords/flags on delivery
by Matt Doran 08 Jan '09

08 Jan '09

Hi there, We've been long time users of Dovecot, and have found it a great IMAP server. I don't think we've had any serious problems in the 3-4 years of use. So great work. :) We have a IMAP inbox that is accessed by a number of different users from Thunderbird. We have a rule in Thunderbird to flag new emails as "TO DO", so someone can unflag the email once it has been actioned. This process works fairly well for a simple workflow, but problems arise when someone connects to the inbox with a Thunderbird instance that doesn't have the "TO DO" rule configured. The email will not be flagged properly. :( I'd like to be able to set this flag/keyword when the mail is delivered to the inbox, on the server side. That way the flag will be set no matter which client accesses the Inbox first. We currently use mail drop for our server-side mail filtering .... and would like to do a similar thing with this flagging process. We're using Dovecot 1.0.15 on Debian Testing, and use Maildir storage and maildrop as our delivery agent. I've read about how the keywords and Thunderbird labels work in the wiki article here (http://wiki.dovecot.org/MailboxFormat/Maildir) So I could probably write some sort of script to query the "dovecot-keywords" file, and rename the Maildir file to set the appropriate flag. But this sounds a like a bit of a hack, and maybe a little dangerous. Does anyone have any recommendations as to how I could achieve something like this? I'm keen to hear any ideas, whether it's through scripting, or some sort of scriptable/command-line IMAP client. Ideally, we'd have a way to set the flag at the time when the mail is delivered.... or when the first client retrieves any new mail?

[Dovecot] Default dirs in ./configure?
by Peter Lindgren 08 Jan '09

08 Jan '09

Hi! I try to build a new 1.1.7 installation. Since I'm not a large sysadmin, just my own private mail server admin, I just wonder why the sysconf and state dirs defaults to $prefix? Maybe I'm old-school, but isn't /etc and /var, respectively, a better default than /usr/local? Should require two new variables in the configure script, though. (and yes, I know I set them with --sysconfdir=/etc --localstatedir=/var --sharedstatestatedir=/var ) /Peter -- Peter Lindgren http://www.norrskenkonsult.com
