[Dovecot] INBOX.INBOX.Sent causes problems in 2.0
by Christoph Bußenius 12 Oct '12

12 Oct '12

Hi, we have our namespace rooted at "INBOX.". Sometimes, users have folders like "INBOX.INBOX.Sent" or "INBOX.INBOX.INBOX.Sent". I do not know why these folders are created; I suspect it is due to buggy MUAs. If a mailbox like INBOX.INBOX.Sent exists, then in some cases Dovecot counts all messages in INBOX twice. This behavior can be demonstrated as follows: 1) Create a folder named "INBOX.INBOX.Sent" (using the IMAP CREATE command) 2) Save a message to "INBOX" (in my example the message is 7 MB) 3) dovecot-quota contains: priv/quota/storage 7129025 priv/quota/messages 1 4) doveadm quota recalc -u user1 5) Now dovecot-quota contains priv/quota/storage 14258050 priv/quota/messages 2 I.e. the user will experience that his quota fills up very fast. "doveadm -f flow fetch -u user1 'mailbox guid' ALL" prints: mailbox=INBOX guid=040ce73645177850497d000040c59ffc mailbox=INBOX guid=040ce73645177850497d000040c59ffc However, "doveadm -f flow fetch -u user1 'mailbox guid' mailbox INBOX" prints the message only once: mailbox=INBOX guid=040ce73645177850497d000040c59ffc How can we prevent this kind of confusion? What I'd like most is prevent the creation of these weird folders. Most MUAs have problems listing them properly, especially if both "INBOX.Sent" and "INBOX.INBOX.Sent" exist. Dovecot 2.1 does not seem to count anything twice. Cheers, Christoph Config: # 2.0.21: /usr/local/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (6224) # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = quota mail_uid = vmail namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { quota = dict:ROOT::file:%h/dovecot-quota quota_rule = *:storage=5G } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { process_limit = 5000 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = quota imap_quota } And the contents of the "users" file: user1:{plain}secret:::user1:/mail/users/user1:: -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] [PATCH] dovadm plugins underlinking
by Natanael Copa 12 Oct '12

12 Oct '12

Hi, Running doveadm on Alpine Linux will show various underlinking errors: /usr/bin/doveadm: symbol 'acl_user_module': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. /usr/bin/doveadm: symbol 'acl_identifier_parse': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. ... (complete list is found here: http://bugs.alpinelinux.org/issues/1274) I understand that those are "harmless" (at least as long as you dont use those plugins), and even if some dynamic linkers are forgiving, the doveadm plugin modules are technically underlinked. The lib10_doveadm_acl_plugin.so uses symbol acl_user_module: $ nm -D /usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so | grep acl_user_module U acl_user_module That symbol is defined in lib01_acl_plugin.so: $ nm -D /usr/lib/dovecot/lib01_acl_plugin.so | grep acl_user_module 000000000020fb80 D acl_user_module Which means that lib10_doveadm_acl_plugin.so should be directly linked to lib01_acl_plugin.so. But it is not: $ readelf -d /usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [librt.so.0.9.32] 0x0000000000000001 (NEEDED) Shared library: [libc.so.0.9.32] Below is a patch that should solve it. --- diff -r 4d268e810c15 src/plugins/acl/Makefile.am --- a/src/plugins/acl/Makefile.am Mon Oct 08 08:53:54 2012 +0300 +++ b/src/plugins/acl/Makefile.am Wed Oct 10 11:03:49 2012 +0200 @@ -10,7 +10,8 @@ -I$(top_srcdir)/src/doveadm NOPLUGIN_LDFLAGS = -lib10_doveadm_acl_plugin_la_LDFLAGS = -module -avoid-version +lib10_doveadm_acl_plugin_la_LDFLAGS = -module -avoid-version -Wl,-rpath,$(moduledir) +lib10_doveadm_acl_plugin_la_LIBADD = $(module_LTLIBRARIES) lib01_acl_plugin_la_LDFLAGS = -module -avoid-version module_LTLIBRARIES = \ diff -r 4d268e810c15 src/plugins/expire/Makefile.am --- a/src/plugins/expire/Makefile.am Mon Oct 08 08:53:54 2012 +0300 +++ b/src/plugins/expire/Makefile.am Wed Oct 10 11:03:49 2012 +0200 @@ -14,7 +14,8 @@ -I$(top_srcdir)/src/doveadm NOPLUGIN_LDFLAGS = -lib10_doveadm_expire_plugin_la_LDFLAGS = -module -avoid-version +lib10_doveadm_expire_plugin_la_LDFLAGS = -module -avoid-version -Wl,-rpath,$(moduledir) +lib10_doveadm_expire_plugin_la_LIBADD = $(module_LTLIBRARIES) lib20_expire_plugin_la_LDFLAGS = -module -avoid-version module_LTLIBRARIES = \ diff -r 4d268e810c15 src/plugins/fts/Makefile.am --- a/src/plugins/fts/Makefile.am Mon Oct 08 08:53:54 2012 +0300 +++ b/src/plugins/fts/Makefile.am Wed Oct 10 11:03:49 2012 +0200 @@ -11,7 +11,8 @@ -I$(top_srcdir)/src/doveadm NOPLUGIN_LDFLAGS = -lib20_doveadm_fts_plugin_la_LDFLAGS = -module -avoid-version +lib20_doveadm_fts_plugin_la_LDFLAGS = -module -avoid-version -Wl,-rpath,$(moduledir) +lib20_doveadm_fts_plugin_la_LIBADD = $(module_LTLIBRARIES) lib20_fts_plugin_la_LDFLAGS = -module -avoid-version module_LTLIBRARIES = \ diff -r 4d268e810c15 src/plugins/quota/Makefile.am --- a/src/plugins/quota/Makefile.am Mon Oct 08 08:53:54 2012 +0300 +++ b/src/plugins/quota/Makefile.am Wed Oct 10 11:03:49 2012 +0200 @@ -11,7 +11,8 @@ -I$(top_srcdir)/src/doveadm NOPLUGIN_LDFLAGS = -lib10_doveadm_quota_plugin_la_LDFLAGS = -module -avoid-version +lib10_doveadm_quota_plugin_la_LDFLAGS = -module -avoid-version -Wl,-rpath,$(moduledir) +lib10_doveadm_quota_plugin_la_LIBADD = $(module_LTLIBRARIES) lib10_quota_plugin_la_LDFLAGS = -module -avoid-version module_LTLIBRARIES = \ diff -r 4d268e810c15 src/plugins/zlib/Makefile.am --- a/src/plugins/zlib/Makefile.am Mon Oct 08 08:53:54 2012 +0300 +++ b/src/plugins/zlib/Makefile.am Wed Oct 10 11:03:49 2012 +0200 @@ -11,7 +11,8 @@ -I$(top_srcdir)/src/doveadm NOPLUGIN_LDFLAGS = -lib10_doveadm_zlib_plugin_la_LDFLAGS = -module -avoid-version +lib10_doveadm_zlib_plugin_la_LDFLAGS = -module -avoid-version -Wl,-rpath,$(moduledir) +lib10_doveadm_zlib_plugin_la_LIBADD = $(module_LTLIBRARIES) lib20_zlib_plugin_la_LDFLAGS = -module -avoid-version module_LTLIBRARIES = \

[Dovecot] imap proxy setup - "killed with signal 11"
by btb 12 Oct '12

12 Oct '12

hi- i'm setting up an imap proxy in front of a novell groupwise server. it seems to so far be partially working, but dovecot is having trouble in certain cases. i expect that it's ultimately due to what i believe is a very poor implementation of imap provided by groupwise [at least based on other experiences in the past] - but that's a big part of why i'd like to have dovecot in between it and clients. below is information collected during starting of dovecot, opening/initial connection from a client [os x mail.app], closing of the client, and stopping of dovecot. os is ubuntu 12.10 development/beta, dovecot is 2.1.7 courtesy of ubuntu's packages. log entries: Oct 11 13:24:33 halo dovecot: master: Dovecot v2.1.7 starting up Oct 11 13:24:49 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14171, TLS, session=<iHgu2cvLlwAKRChu> Oct 11 13:24:50 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14174, TLS, session=<t1E/2cvLoQAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14176, TLS, session=<OZlM2cvLqgAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14178, TLS, session=<d3NU2cvLsQAKRChu> Oct 11 13:24:51 halo dovecot: imap(jdoe): Connection closed in=16 out=350 Oct 11 13:24:52 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14180, TLS, session=<oxNa2cvLtAAKRChu> Oct 11 13:24:52 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:52 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14176 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:57 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14178 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14182, TLS, session=<FUCv2cvLuAAKRChu> Oct 11 13:24:58 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:58 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14180 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14182 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14184, TLS, session=<DQkF2svLuwAKRChu> Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14184 killed with signal 11 (core dumped) Oct 11 13:25:09 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:09 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14174 killed with signal 11 (core dumped) [repeats] Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: auth: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: ssl-params: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) gdb backtrace: ~ >gdb /usr/lib/dovecot/imap /var/cache/imapproxy/jdoe/core GNU gdb (GDB) 7.5-ubuntu Copyright (C) 2012 Free Software Foundation, Inc.

[Dovecot] per-user quotas
by David Mehler 12 Oct '12

12 Oct '12

Hello, I've got quotas set up on an all-user basis on my system, it's a Postfix, Dovecot, Mysql virtual users setup. Currently I have each user getting a 1GB quota with these settings in 90-quota.conf: plugin { quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } plugin { quota = maildir:User quota } While this works it's not what I want for all users. Say I add a virtual user called user1 to the mysql database but he's a test user and I only want that user to have 25 megabytes of storage, reading the wiki on quotas per-user items such as for example in a database overrides the global items above, is this right? If so, I'm hoping I'm not going to have to redo my entire user database, some users will have per-user quotas while I'll let others have the global quota. Thanks. Dave.

[Dovecot] Feature Request
by Marc Perkel 12 Oct '12

12 Oct '12

It would be handy (for me) if there were a userdb where a directory structure defined the db. userdb stat { mail_location=maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } userdb stat { mail_location=maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } The idea being that if the first directory doesn't exist then it will try the second one.

[Dovecot] Multiple Maildir?
by Marc Perkel 12 Oct '12

12 Oct '12

OK - Getting close to everything working in my weird configuration. Here's a problem I'm still having. I'm authenticating with this: userdb { driver = sql args = /etc/dovecot/master-combined-sql.conf } Default mail location: mail_location = maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs However - what I'd like to do is if the mail location doesn't exist then I want to try a second mail location: mail_location = maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs How do I do that? Thanks in advance

[Dovecot] Shared Squat index for public mailboxes
by Frerich Raabe 11 Oct '12

11 Oct '12

Hi, I'm running Dovecot 1.2.17 for serving mail via IMAP as well as for providing access to a mailing list archive. The archive is implemented as a public read-only mailbox with per-user index files (i.e. the \Seen flags are per-user). I recently enbled the Squat plugin to accelerate searches in the message bodies and noticed that every user (I'm using a virtual user setup) gets his own dovecot.index.search and dovecot.index.search.uids copies. Is it possible to share those files among all users of the system? The squat plugin appears to store the search indices among the other index files (as explained on http://wiki.dovecot.org/Plugins/FTS/Squat) no matter what; I considered storing a central copy of the index files somewhere and then creating symlinks for all users. It should be ok as far as file-permissions go since all mail is owned by a single vmail system user, but I wonder whether the indices are really the same (I noticed their md5 checksums differ) and whether there may be file locking issues in case two users search message bodies simultaneously. Can anybody shed some light? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing
