Moving dovecot/maildir to new host, dovecot.* files
by John Gateley 26 May '17

26 May '17

Hello, I've done a fair amount of searching, and couldn't find a definitive answer. I am moving my dovecot/postfix servers and mail in Maildir formats to a new host. When I move the Maildir directories, what should I do with the dovecot.index/cache/log/etc. files? I know I can filter them out, and dovecot will recreate them, but is that the best approach? I am thinking of the following: Shut down postfix and dovecot on both the new and old server rsync the maildirs from the old server to the new server start up postfix/dovecot on the new server verify all is okay switch DNS from old server to new server. Is this the best approach with minimal impact to mail users? Thanks very much John

Public mailboxes and IPA (LDAP)
by Ranbir 26 May '17

26 May '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi Everyone, I have a working Dovecot server that is using my IPA domain to lookup users and passwords. I also have a "public" namespace that has the inboxes for public email accounts. Everything is working for "regular" private email boxes. But, I can't see new messages delivered to any of the public inboxes. Incoming emails get delivered to the correct locations for the public inboxes: I just don't see them in my email clients. I'm not sure what the problem is since I don't see an error in the dovecot logs. I also don't want to use the home directory location as provided by the IPA domain. I've worked around it by using file system symlinks, but I'd much rather just ignore the IPA provided home directory. I'm wondering if my workaround is the culprit behind new messages to the public folders not being seen by the client. Here's my config: # 2.2.10: /etc/dovecot/dovecot.conf auth_cache_negative_ttl = 0 auth_cache_size = 1 k auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/imap.keytab auth_mechanisms = plain gssapi auth_realms = SOME.REALM auth_username_format = %Ln auth_verbose = yes first_valid_uid = 1000 hostname = server listen = 1.1.1.1 mail_gid = virtual mail_location = maildir:~/Maildir mail_plugins = quota acl mail_uid = virtual managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded- character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl namespace { location = maildir:/var/spool/mail/domain.tld/public prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/conf.d/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile quota = maildir:User quota quota_rule = *:storage=500M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@%d protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { inet_listener { address = 1.1.1.1 port = 17900 } unix_listener auth-userdb { group = virtual mode = 0600 user = virtual } } service imap-login { process_min_avail = 2 service_count = 1 } service lmtp { inet_listener lmtp { address = 1.1.1.1 port = 24 } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = /etc/dovecot/conf.d/dovecot-ldap-userdb.conf.ext default_fields = uid=virtual gid=virtual driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = quota acl sieve } protocol lda { mail_plugins = quota acl sieve } protocol imap { mail_plugins = quota acl imap_quota imap_acl } - -- Ranbir -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJZJz5lAAoJEN7T/ly5z1dituQQAIvq/DyDq5JbyREpopj5XcgN RjuvFAf2VuR9ieBnJ66GZPS9kcLZusqTzFyBczJmvq5sHRR8+UvRhsDVGGRNGFS+ 5b6oJNbP5BYP+93Ik8Ai7XgkaSfzIVg6cpru0uzMN0FvzQWXGONKQhMI0dFF+rFf 377gxho3AiAUxffX/vRhOvmE5/loJL9g8WDd6qAdZ6Ow3X3ISIWTo8ICWcndxWJK WU+/vsXfg1Up96M9X38FIhCBVcJG+igUXqZ3/0+N4at/L6BI5BWmG21XpaReGORo QjVaDIeFw4supnaKJszYiiYU1vQRHyvW5p2V0l1Q7mIh/sqANYhqJpziCP9yx1gN g0iv32V2EPxI44ympuhFtAslqyyGhfMtHOsufQ/QbrwjJAML/TRJYuyqh0hiZ+0h anhkDmkb0mlJlroPYJatiqJZqOYNRmtT8QpRMqapELDBo/Rc2LzqnkrgEso2XjI3 yLYXSgV1cY7HNJzhIvmPWZDncF4LW5o3JpidCdcDRnXvDUc3tyb/qRQkvI1+Zycw P5n2r+9BcSWA194TU+QPzvdB9MKQ+Cn3dM0HwYkEqQXH7BVgKKvXobaM+mOgBjLL Ais+yc0aeoKV5r3ln74HPRyXfw0Zp9g128BwzQG597kPhXaXb9Hd5o58LMkdMfxs 5ycn42U8p2ZiKHFDx9vO =swZL -----END PGP SIGNATURE-----

"@LIBICU_CFLAGS@: No such file or directory" during libtool command for lib-fts (cross compile)
by awl1 26 May '17

26 May '17

Hello, I am a complete newbie to dovecot, but do have reasonable experience in compiling Unix/Linux software. I am currently trying to do a cross-compile of dovecot-2.29.1 to be used on my home office Thecus NAS (host: Thecus kernel 2.6.33 on 32-bit Intel Atom: "i686-nptl-linux-gnu"; my build machine has Ubuntu 16.04.2 LTS) "from ground up", i.e. I need to build and provide all dovecot dependencies from within my module. My compiler toolchain (using gcc-5.2.0) has been set up properly using ct-ng and works completely fine. I also have already successfully cross-compiled/built almost all dovecot dependencies (zlib, bzip2, xz, lz4, openssl-1.0.2, clucene-git, snowball-git, libexttextcat, icu) - i.e. including icu - and installed them properly into my cross-compile build root (/raid/data/module/Dovecot/sys as defined by Thecus module spec). My dovecot configure/make command is as follows: === export PKG_CONFIG=/usr/bin/pkg-config export PKG_CONFIG_PATH=/raid/data/module/Dovecot/sys/lib/pkgconfig export CC=$HOME/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-gcc export CFLAGS="" export LDFLAGS="-L/raid/data/module/Dovecot/sys/lib -Wl,-rpath,/raid/data/module/Dovecot/sys/lib" export LIBS="" # -llib export CPPFLAGS=-I/raid/data/module/Dovecot/sys/include export CPP=$HOME/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-cpp export CXX=$HOME/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-g++ export CXXFLAGS="" export LT_SYS_LIBRARY_PATH=/raid/data/module/Dovecot/sys/lib export CXXCPP=$HOME/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-cpp ./configure --host i686-nptl-linux-gnu \ --prefix=/raid/data/module/Dovecot/sys \ --libdir=/raid/data/module/Dovecot/sys/lib \ --localstatedir=/raid/data/module/Dovecot/com \ --sharedstatedir=/raid/data/module/Dovecot/var \ --disable-silent-rules \ --with-notify=inotify \ --with-lucene \ --with-stemmer \ --with-textcat \ --with-icu \ --with-solr \ --with-zlib \ --with-bzlib \ --with-lzma \ --with-ssl=openssl \ --with-ssldir=/raid/data/module/Dovecot/sys/etc/ssl \ --with-storages=mdbox,sdbox,maildir,mbox,cydir,imapc,pop3c \ --with-moduledir=/raid/data/module/Dovecot/sys \ --with-gnu-ld \ --with-sysroot=/raid/data/module/Dovecot/sys \ --with-libiconv-prefix=/raid/data/module/Dovecot/sys \ --with-libintl-prefix=/raid/data/module/Dovecot/sys make === and completes configuration just fine, but the make step runs into the following issue which I am unable to resolve even after several hours of investigation, so I am completely stuck at this point... :-( === (...) make[3]: Leaving directory '/home/andreas/Thecus/Dovecot/dovecot-2.2.29.1/src/lib-dovecot' Making all in lib-fts make[3]: Entering directory '/home/andreas/Thecus/Dovecot/dovecot-2.2.29.1/src/lib-fts' make all-am make[4]: Entering directory '/home/andreas/Thecus/Dovecot/dovecot-2.2.29.1/src/lib-fts' /bin/bash ../../libtool --tag=CC --mode=compile /home/andreas/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -I../../src/lib-mail -I../../src/lib-fts -I/raid/data/module/Dovecot/sys/include/libexttextcat/ @LIBICU_CFLAGS@ -DUDHRDIR=\""../../src/lib-fts"\" -DDATADIR=\"/raid/data/module/Dovecot/sys/share/dovecot\" -DTEST_STOPWORDS_DIR=\""../../src/lib-fts/stopwords"\" -I/raid/data/module/Dovecot/sys/include -std=gnu99 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/raid/data/module/Dovecot/sys/include -MT fts-filter.lo -MD -MP -MF .deps/fts-filter.Tpo -c -o fts-filter.lo fts-filter.c libtool: compile: /home/andreas/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -I../../src/lib-mail -I../../src/lib-fts -I/raid/data/module/Dovecot/sys/include/libexttextcat/ @LIBICU_CFLAGS@ -DUDHRDIR=\"../../src/lib-fts\" -DDATADIR=\"/raid/data/module/Dovecot/sys/share/dovecot\" -DTEST_STOPWORDS_DIR=\"../../src/lib-fts/stopwords\" -I/raid/data/module/Dovecot/sys/include -std=gnu99 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/raid/data/module/Dovecot/sys/include -MT fts-filter.lo -MD -MP -MF .deps/fts-filter.Tpo -c fts-filter.c -fPIC -DPIC -o .libs/fts-filter.o i686-nptl-linux-gnu-gcc: error: @LIBICU_CFLAGS@: No such file or directory Makefile:714: recipe for target 'fts-filter.lo' failed make[4]: *** [fts-filter.lo] Error 1 make[4]: Leaving directory '/home/andreas/Thecus/Dovecot/dovecot-2.2.29.1/src/lib-fts' Makefile:562: recipe for target 'all' failed === As far as I can tell, my pkgconfig file (/raid/data/module/Dovecot/sys/lib/pkgconfig/icu-i18n.pc) also seems to be fine: === # Copyright (C) 2016 and later: Unicode, Inc. and others. # License & terms of use: http://www.unicode.org/copyright.html # Copyright (C) 2010-2013, International Business Machines Corporation.

Dovecot/Sieve shortcuts?
by Adam Shostack 24 May '17

24 May '17

Hi, Is there a clean way to match on an email address the way procmail ^TO_ did? that was a macro which expanded to (^((Original-)?(Resent-)?(To|Cc|Bcc)|(X-Envelope |Apparently(-Resent)?)-To):(.*[^-a-zA-Z0-9_.])?) so you could write * ^TO_dovecot dovecot and grab messages to the list. In sieve, I find myseld writing ["To","cc"] and wonder if there's a better way. Adam

dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11
by dovecot＠jeffandjessi.com 24 May '17

24 May '17

Trying to track down a dovecot issue .... The error message is: dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11 (core not dumped - set service auth-worker { drop_priv_before_exec=yes }) The setup is dovecot 2.2.29.1 with passwd and mysql auth db's and a very basic config. both authentications work ... the symptom is that after a connection is made the auth worker loads and emails are downloaded and everything "is fine". However, about 30 second to a minute after the connection is done the process dies with the error message. Then the process starts all over with on the next checking of email ,but again everything "works" just seeing this error and the process dieing each time? enabled all extra verbose logging ,but nothing gives any clues.... Tried to enable core dumps ,but couldnt get core dumps to work ? The only thing is that a recently pkgsrc (netbsd) update create 2 packages, one for dovecot and one for mysql plugin , sense then now this error appears. ,but it appears the .so lib files are installed and linked correctly. Double checked all file permissions and user permissions as well as chroot , etc, etc, ,etc.... cant seem to narrow this one down .... any ideas on trouble shooting would be great .... even tried running a trace with gdb -p on the process ,but it just dies with a signal 11 ....

v2.2.30 release candidate released
by Timo Sirainen 24 May '17

24 May '17

https://dovecot.org/releases/2.2/rc/dovecot-2.2.30.rc1.tar.gz https://dovecot.org/releases/2.2/rc/dovecot-2.2.30.rc1.tar.gz.sig There are a couple of changes still coming, but now would be a good time to make sure anything unexpected hasn't broken. The final release should be out early next week. * auth: Use timing safe comparisons for everything related to passwords. It's unlikely that these could have been used for practical attacks, especially because Dovecot delays and flushes all failed authentications in 2 second intervals. Also it could have worked only when passwords were stored in plaintext in the passdb. * master process sends SIGQUIT to all running children at shutdown, which instructs them to close all the socket listeners immediately. This way restarting Dovecot should no longer fail due to some processes keeping the listeners open for a long time. + auth: Add passdb { mechanisms=none } to match separate passdb lookup + auth: Add passdb { username_filter } to use passdb only if user matches the filter. See https://wiki2.dovecot.org/PasswordDatabase + dsync: Add dsync_commit_msgs_interval setting. It attempts to commit the transaction after saving this many new messages. Because of the way dsync works, it may not always be possible if mails are copied or UIDs need to change. + imapc: Support imapc_features=search without ESEARCH extension. + imapc: Add imapc_features=fetch-bodystructure to pass through remote server's FETCH BODY and BODYSTRUCTURE. + imapc: Add quota=imapc backend to use GETQUOTA/GETQUOTAROOT on the remote server. + passdb imap: Add allow_invalid_cert and ssl_ca_file parameters. + If dovecot.index.cache corruption is detected, reset only the one corrupted mail instead of the whole file. + doveadm mailbox status: Add "firstsaved" field. + director_flush_socket: Add old host's up/down and vhost count as parameters - More fixes to automatically fix corruption in dovecot.list.index - dsync-server: Fix support for dsync_features=empty-header-workaround - imapc: Various bugfixes, including infinite loops on some errors - fts-lucene: Fix it to work again with mbox format - vpopmail: Fix compiling

dovecot 2.2.22 postfix 3.1.1 I’m seeing "SASL NTLM authentication failed: {long_hash}” in mail.log. Is there a way to log the SASL username? I think postfix is logging what Dovecot SASL is returning so I hope I am asking on the right list. Regards, Bradley Giesbrecht (pixilla)

dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11

Trying to track down a dovecot issue .... The error message is: dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11 (core not dumped - set service auth-worker { drop_priv_before_exec=yes }) The setup is dovecot 2.2.29.1 with passwd and mysql auth db's and a very basic config. both authentications work ... the symptom is that after a connection is made the auth worker loads and emails are downloaded and everything "is fine". However, about 30 second to a minute after the connection is done the process dies with the error message. Then the process starts all over with on the next checking of email ,but again everything "works" just seeing this error and the process dieing each time? enabled all extra verbose logging ,but nothing gives any clues.... Tried to enable core dumps ,but couldnt get core dumps to work ? The only thing is that a recently pkgsrc (netbsd) update create 2 packages, one for dovecot and one for mysql plugin , sense then now this error appears. ,but it appears the .so lib files are installed and linked correctly. Double checked all file permissions and user permissions as well as chroot , etc, etc, ,etc.... cant seem to narrow this one down .... any ideas on trouble shooting would be great .... even tried running a trace with gdb -p on the process ,but it just dies with a signal 11 ....
