No, this is a dovecot server running in my own laptop. I guess some computer crash left the mail in an inconsistent state, and I need to assert the extend of the problem. A well designed system should not lose email, even when crashes are involved. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

Segfault dovecot 2.2.9
by Simon Gareste 29 Jul '14

29 Jul '14

Hi all, When trying to set up dovecot, I somehow managed to get a segfault. Trying to launch dovecot from command line (simply execute 'dovecot') results in the error message: Segmentation fault (core dumped) Trying dovecot -n results in pretty much the same: # 2.2.9: /etc/dovecot/dovecot.conf Segmentation fault (core dumped) Looking at syslog, I see doveconf[3676]: segfault at 200 ip 00007fbb93c4fcb3 sp 00007fff005b4c10 error 4 in libc-2.19.so[7fbb93c04000+1bc000] I tried but couldn't find the core dump anywhere on the server. Any help on this would be appreciated too. I (trying to ) run it with postfix, on an Ubuntu 14.04 (Linux mail2.arturia.com 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux), brand new server. What troubles me even more is that I just set up successfully another mail server a week ago, with the same configuration (diffing the conf folders) except for log or mailbox paths (driver and stuff are the same). In the google search I've done, I saw some stuff about openssl: both servers are running 1.0.1f, since one is running fine, I guess this is not the culprit. One difference I noticed between the two servers is that on the failing one, there is no /var/run/dovecot. I presume this folder and its files are created once dovecot is launched, so that's why it's not present, and is only a symptom of the failure, not a cause? Thanks for your help, and please tell me what other information I could provide to help. Simon

Multiple passwords with sql authentication
by BlackVoid 29 Jul '14

29 Jul '14

I'm currently working on a control panel which is using postfix, dovecot and other applications and I want to add application specific passwords to increase security. I found one solution [1], however it requires the password to be included in the query which is something I do not want to do, because the query may be written in clear-text to log-files. So I'm wondering if there is a way to have multiple passwords with dovecot without risking passwords being leakied in clear-text to log-files.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 28 Jul '14

28 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system. Unfortunately I can't get dsync to do that. Using a config that specifies only one namespace allows me to convert either mboxes or Maildirs to mdboxes but not both.

ACLs on Top level mailboxes.
by Dan Carroll 28 Jul '14

28 Jul '14

Hello, I’m in the process of migrating a mail server to new hardware. At the same time, I’ve made the decision to switch from courier to dovecot (v2.2.13) and from what I have seen so far I’m pretty happy. I have two questions for the list. I’d like my users mailboxes (Maildir format) to look like this: Inbox UserCreatedSubFolder1 UserCreatedSubFolder2 … Sent UserCreatedSubFolder3 Drafts Trash Junk Archives The Top level folders (Sent, Drafts etc) are all “Special” and I do not wish the users to be able to delete them. I also don’t want them to create new Top level folders. This will force all custom folders to be under a Top Level folder. The Maildir format currently looks like this: ~/Maildir/cur ~/Maildir/new ~/Maildir/tmp ~/Maildir/.INBOX/.UserCreatedSubFolder1/cur ~/Maildir/.INBOX/.UserCreatedSubFolder1/new ~/Maildir/.INBOX/.UserCreatedSubFolder1/tmp ~/Maildir/.Sent/cur ~/Maildir/.Sent/new ~/Maildir/.Sent/tmp etc…. I can get ACLs working with dovecot-acl files, and the permission I need (I think is) “owner lrwstipe”. But if I put it into the ~/Maildir directory, then it applies to Inbox. I’ve tried creating an .INBOX dir and putting it in there but that did not work. I also tried some global-acl file settings but I could not make that work either. Basically, I’m wondering how to apply ACLs to the Top level and have different ACLs for the actual inbox when using this scheme. I’m not opposed to changing the Maildir format, but that would mean a lot of work re-doing proemial scripts. My second question relates to migration. Is it enough that I copy the Maildir structure and simply delete the courier files or is it a lot better to use a courier->dovecot migration tool? I realise folder subscriptions would be lost but that’s OK, I’ll recreate them manually anyway. Thanks for your time. -Dan

After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character on a Linux system
by David Davidov 28 Jul '14

28 Jul '14

We have following issue: After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character. This was not possible with our previous version 2.1. Tested. Our Dovecot runs on Debian Wheezy system. According http://wiki2.dovecot.org/Plugins/Listescape this should be disabled on a Posix system. We use the usual separator '.' as you can see in the config file later. Issue can be reproduced using outlook 2013. On the file system this is the representation of the "Family/Friends" folder /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/new /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/tmp /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/cur Doveadm does not lists properly the folder doveadm mailbox list -usteve(a)alltimes.com |grep -i Family INBOX.Family This is the server configuration: ----------------------- dovecot -n # 2.2.13: /dovecot/etc/dovecot/dovecot.conf # OS: Linux 3.2.59-grsec x86_64 Debian 7.6 auth_username_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890@!#$&\'*+=?^_`{|}~.-" base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pid=%p %c mail_access_groups = vchkpw mail_fsync = never mail_plugins = quota stats namespace { inbox = yes location = maildir:~/Maildir:INDEX=/home/vpopmail/dovecot-indexes/%d/%n prefix = INBOX. separator = . type = private } passdb { args = /home/vpopmail/bin/chkpw driver = checkpassword } plugin { acl = vfile:/dovecot/acls quota = maildir quota_rule = INBOX.Trash:ignore stats_command_min_time = 1 mins stats_domain_min_time = 12 hours stats_ip_min_time = 12 hours stats_memory_limit = 64 M stats_refresh = 30 secs stats_session_min_time = 15 mins stats_track_cmds = yes stats_user_min_time = 1 hours } protocols = imap pop3 service imap-login { executable = /dovecot/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_min_avail = 16 service_count = 0 } service imap { executable = /dovecot/libexec/dovecot/imap-ld-hack process_limit = 1500 vsz_limit = 256 M } service pop3-login { process_min_avail = 16 service_count = 0 } service pop3 { executable = /dovecot/libexec/dovecot/pop3-ld-hack process_limit = 1500 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } ssl_ca = </apache/conf/ssl.crt/server-ca.crt ssl_cert = </apache/conf/ssl.crt/server.crt ssl_cipher_list = ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP ssl_key = </apache/conf/ssl.key/server.key userdb { driver = vpopmail } userdb { driver = prefetch } protocol imap { imap_client_workarounds = mail_max_userip_connections = 100 mail_plugins = quota stats acl imap_quota imap_stats } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota stats acl pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = yes pop3_no_flag_updates = yes pop3_uidl_format = %f } ----------------------- We need a way to prevent creation of those folders, because our users create several of them a day.

mdbox "doveadm purge" strategy
by Jesus Cea 28 Jul '14

28 Jul '14

Hi there. I am using mdbox storage with great success but I am seeing something I find strange and I would like to compare notes with you. When doing "doveadm purge", "m.*" files with non deleted messages are left alone, but "m.*" files with deleted messages copy the "non deleted" messages to a newly created "m.*" file and delete the original. Good so far. What surprises me is that the newly created "m.*" files are not fullsize. they can be "small" files, not using the 2MB max size I have configured for mdbox storage. Moreover, those files stay in that size forever, no new messages are appended ever. I guess each old "m.*" file with deleted messages generates a new independent "m.*" containing only the non deleted messages. I wonder if that is the case and if that is a fundamental issue that can't be changed. I would like my "m.*" files to use the full configured mdbox size, instead of having quite a few of new SMALL "m.*" files. Thanks for your time and attention!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

struggling with pigeonhole date extensions
by Laeeth Isharc 27 Jul '14

27 Jul '14

I am struggling with how to use the date extension for Dovecot/Pigenhole implementation of Sieve email filtering language. I have read RFC 5260 several times and tried different things with no luck. I would like to place all messages this year up till the end of March into the specified mail folder. What the snippet below actually seems to do is take any messages this year (whether before or after March). Any thoughts? if allof(date :value "eq" :originalzone "date" "year" "2014", date :value "le" :originalzone "date" "month" "3") { fileinto "INBOX/2014 up to Mar"; stop; } Incidentally, it's puzzling how sparse the ecosystem seems to be for managing sieve scripts given the importance of email and the unmanageability of volumes these days without rules. What would be nice to have is something like the Outlook rule manager as a front end and server side sieve scripts on the back. I looked at Modoboa (which seems to be the only standalone option), but it's a bit heavy for my taste and I struggled to configure it in the time I had available. Thanks in advance.

IMAP forward boxes
by Andre Dietrich 26 Jul '14

26 Jul '14

Hi all, since a few weeks I'm experimenting with some "IMAP forward boxes", but I didn't find a satisfactory solution yet. Target function is a directory structure like following in a shared mailbox: /intern/users/fred /intern/users/ted /intern/users/alice The idea is, that a mail, moved to the directory "/intern/users/fred" via IMAP-client will be forwarded to "fred(a)test.domain" without modifying the mail (except the header line "delivered to:"). So if you get a mail in your inbox and want fred to answer it, you drag'n'drop it to /intern/users/fred. Fred gets the mail in his inbox and can answer it. To share all inboxes, to drop mails directly to them, is not an option, because I don't want everybody to see all other inboxes mails. Only to apply "-w-" ACL rights isn't an option either, because it seems to irritate the mail clients. Some month ago I had a partially working solution using a cron bash script. The script read the mails in the cur and new folders, processed the folders path and passed it to sendmail. It's ok, but it has to run quite often to get an adequate forwarding time and on sendmail errors mails got lost without any notification. It would be nice to have a dot-forward file in this subfolder (like in the qmail mailbox root), which is processed by dovecot when a mail is dropped in. Is it possible to solve this with a sieve script, a dot-forward file, or something similar ? I'm grateful for all solutions / ideas ! thx! Andre

Pigeonhole Sieve LDAP support
by Stephan Bosch 25 Jul '14

25 Jul '14

Hi, Yesterday, I committed two important and rather big changes to the Pigeonhole repository. The first creates a generic interface for implementing Sieve script storages. It was already possible to some extent to read Sieve scripts from other sources than the local filesystem, such as Dovecot dict, but that was still pretty limited, as it was not possible to do this with sieve_before/sieve_after. This is now supported. But, more importantly, ManageSieve did not support storing Sieve scripts on locations other than the local filesystem. Now, alternatives can be implemented. Still, I haven't actually implemented write access to a storage other than the local filesystem yet, but now this would be much easier to achieve. The second creates an LDAP script storage implementation. Much like the dict storage, it is still read-only. It can be compiled directly into the Sieve interpreter, and, alternatively, it can also be compiled as a plugin called sieve_storage_ldap. I've updated the documentation in the sources. For all Xi repository users: I added compilation of LDAP storage as a plugin. Read the INSTALL files and other files referenced therein for more information about how to use the plugin. The plugin is installed as part of the dovecot-ldap package. This is a rather big change, but it should all be backwards compatible in terms of configuration. If you have problems (I heard about one so far), please don't hesitate to notify me. Regards, Stephan.

Maildir migration - using separate INDEX and CONTROL directories?
by Richard Hector 24 Jul '14

24 Jul '14

Hi all, I'm working on a migration from Courier to Dovecot, and the courier-dovecot-migrate.pl seems to work ok, but it puts all the metadata files (dovecot-uidlist etc) in the Maildir, while I want to put them in the appropriate places as specified: mail_location = maildir:~/Maildir:INDEX=/var/mail/meta/index/%d/%1n/%1.1n/%n:CONTROL=/var/mail/meta/control/%d/%1n/%1.1n/%n http://wiki2.dovecot.org/Quota/FS explains why some of these files need to go in different places (which is why I'm doing it), but I haven't seen a complete list of what files will be moved as a result of those directives. Is there a handy tool to move the files to the right places? Or is there a complete list of what files need to go where? Thanks, Richard

Sieve plugin (fc17 + sendmail + roundcube)
by Franck CALLEJA 24 Jul '14

24 Jul '14

Hello, I'm trying to configure sieve plugin on my mail server so that people can do mail filtering (and mostly vacation notification) on their account. The mail server is running fine since 5 years and is based on :- sendmail- dovecot- roundcube It serves 2 differents domains. I've recently installed pigeonhole for fc17, and managed to configure managesieve plugin in roundcube successfully. Users can now manage filters from roundcube. The problem is that filters are not applied when new mails arrives. I've modified dovecot.conf to activate sieve plugin, and the configuration is as follow : # dovecot -n# 2.1.16: /etc/dovecot/dovecot.conf# OS: Linux 3.8.13-100.fc17.x86_64 x86_64 Fedora release 17 (Beefy Miracle) log_path = /var/log/dovecot.logmail_debug = yesmail_location = mbox:~/mail:INBOX=/var/spool/mail/%umanagesieve_notify_capability = mailtomanagesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihavembox_write_locks = fcntlnamespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = }passdb { driver = pam}plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve}protocols = imap pop3 lmtp sieveservice imap-login { service_count = 0}service lmtp { executable = lmtp -L}service pop3-login { service_count = 0}ssl_cert = </etc/pki/dovecot/certs/dovecot.pemssl_key = </etc/pki/dovecot/private/dovecot.pemuserdb { driver = passwd}protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log mail_plugins = " sieve"}protocol lda { mail_plugins = " sieve"} In /etc/sendmail.cf I've this configured :# cat /etc/mail/sendmail.mc divert(-1)dnl include(`/usr/share/sendmail-cf/m4/cf.m4')dnl VERSIONID(`setup for linux')dnl OSTYPE(`linux')dnl define(`confLOG_LEVEL', `15')dnl define(`confDEF_USER_ID', ``8:12'')dnl define(`confTO_CONNECT', `5m')dnl define(`confTRY_NULL_MX_LIST', `True')dnl define(`confDONT_PROBE_INTERFACES', `True')dnl define(`PROCMAIL_MAILER_PATH', `/usr/bin/procmail')dnl define(`ALIAS_FILE', `/etc/aliases')dnl define(`STATUS_FILE', `/var/log/mail/statistics')dnl define(`UUCP_MAILER_MAX', `2000000')dnl define(`confUSERDB_SPEC', `/etc/mail/userdb.db')dnl define(`confPRIVACY_FLAGS', `authwarnings,novrfy,noexpn,restrictqrun')dnl define(`confAUTH_OPTIONS', `A')dnl define(`confMIN_QUEUE_AGE', `15m')dnl define(`confTO_QUEUERETURN', `5m')dnl define(`confMAX_MESSAGE_SIZE', `15000000')dnl define(`confDONT_BLAME_SENDMAIL', `forwardfileingroupwritabledirpath,ForwardFileInUnsafeDirPath,ForwardFileInUnsafeDirPathSafe')dnl define(`confTO_IDENT', `0')dnlFEATURE(`no_default_msa', `dnl')dnl FEATURE(`smrsh', `/usr/sbin/smrsh')dnl FEATURE(`mailertable', `hash -o /etc/mail/mailertable.db')dnl FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl FEATURE(`genericstable',`hash -o /etc/mail/genericstable.db')dnlGENERICS_DOMAIN_FILE(`/etc/mail/generics-domains')dnlFEATURE(redirect)dnl FEATURE(always_add_domain)dnl FEATURE(use_cw_file) FEATURE(use_ct_file)dnl FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl FEATURE(`blacklist_recipients')dnlEXPOSED_USER(`root')dnl DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnlFEATURE(`accept_unresolvable_domains')dnl FEATURE(`relay_hosts_only')dnl FEATURE(`dnsbl', `ipwhois.rfc-ignorant.org',`"550 Mail from " $&{client_addr} " refused.

I think I'm missing some parameters somewhere, but the question is... where ? so any help would be appreciated. RegardsFranck.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 24 Jul '14

24 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system. Unfortunately I can't get dsync to do that. Using a config that specifies only one namespace allows me to convert either mboxes or Maildirs to mdboxes but not both. Using the above config dsync somehow thinks the source and destination are the same: Syncing mailbox for user nima (136 MB) Setup done. doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so doveadm(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima doveadm(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, \ list=yes, subscriptions=yes location=mbox:~/Mail/MBox:INBOX=/var/mail/nima doveadm(nima): Debug: fs: root=/home/nima/Mail/MBox, index=, control=, inbox=/var/mail/nima, alt= doveadm(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir doveadm(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima dsync(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, list=yes, \ subscriptions=yes location=mdbox:/scratch/mail-convert/nima dsync(nima): Debug: fs: root=/scratch/mail-convert/nima, index=, control=, inbox=, alt= dsync(nima): Debug: Namespace #mbox/: Using permissions from /scratch/mail-convert/nima: mode=0700 gid=-1 dsync(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir dsync(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Fatal: Both source and destination mail_location points to same directory: /home/nima/Mail/Maildir What am I doing wrong?

doveconf option "-e"
by Django [BOfH] 24 Jul '14

24 Jul '14

Hi Timo, If I could tell you a little smart wish, I've one for you. ;) Today I'm writing my own configurationdocumentation 'bout Dovecot in my dokuwiki and for documentation purposes I changing some options several times a day. Postfix supports on its own postconf an option -e. So I can set up mostly every configuration-option on the fly. Dovecot's doveconf has no such option. So, I changed the configuration-files and reload my dovecot-daemon. It were grait if doveconf has a similar function, like postconf's option "-e". Maybe you can make a little update to doveconf in one of the upcomming releases? ;) Best regards Django -- "Bonnie & Clyde der Postmaster-Szene!" approved by Postfix-God http://wetterstation-pliening.info http://dokuwiki.nausch.org http://wiki.piratenpartei.de/Benutzer:Django

Problems with custom plugin
by Lukas Mika 24 Jul '14

24 Jul '14

Hi everybody, I wrote a plugin for Dovecot 2.1.something which was based on the information found at http://wiki2.dovecot.org/Design/Storage/Plugins and by studying the mail_log plugin. My plugin can be found here: https://github.com/dim-0/dovecot-mbc It takes the notify plugin's information, that a new mailbox has been created (or an old one been renamed) in order to trigger a custom script (which in my case sets default ACLs for shared mailboxes). This plugin went quite well for a while, but then I recently upgraded Dovecot to version 2.2.9 and now I cannot build my plugin anymore. I get two error messages which both describe the same thing: src/mbc-plugin.c: In function ‘mbc_mailbox_create’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) src/mbc-plugin.c: In function ‘mbc_mail_user_created’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) Obviously the module context nowadays expects another attribute/struct named "reg". However, I cannot find any information about this within the documentation and plugin mentioned above. The only clue I have got yet is the definition in module-context.h: union STRUCT_NAME_module_context { struct STRUCT_NAME_module_register *reg; // it's allowed to have some structure here so it won't waste space. // for example: struct STRUCT_NAME_vfuncs super; }; However, I still cannot make any sense of it (yet). Could you please help me in filling the gap and understanding, what has to be changed? Thanks a lot in advance for an awesome piece of software and any input on this topic, Lukas

FTS lucene indexer-worker segfaulting
by Florian Pritz 24 Jul '14

24 Jul '14

Hi, I've just set up fts-lucene and when I run searches on my inbox or when I run the indexer (`doveadm index INBOX`) I get the following segfault. I've run it multiple times and noticed that the data value is different each time so I guess it doesn't always crash at the same point. I'm running dovecot 2.2.13-1 with clucene 2.3.3.4-8 on Arch Linux.

Dovecot GMail API
by Timo Sirainen 23 Jul '14

23 Jul '14

Hi all, I'm still (mostly) on vacation this week and afterwards lots of different things to do .. But hopefully I'll still get around to answering all the pending mails in this list and applying some of the patches people have sent and get the next v2.2.14 release out. Anyway, people have kept asking about GMail API and Inbox App and how that affects Dovecot. For a while now I've been planning on implementing some kind of a HTTP API for mail access, so might as well use GMail's: http://www.dovecot.fi/dovecot-launches-a-gmail-api-compatible-rest-api-to-e…

SSL certificate problem (SSL alert number 42)
by Boyandin Konstantin 23 Jul '14

23 Jul '14

Hello, After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported. Mail server uses local (created for intranet) CA certificate as root. I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels. Other intranet services work with this local CA quite fine. Thank you in advance.

[patch] enable ECDH auto functions based on feature defines, not on version number
by Hanno Böck 22 Jul '14

22 Jul '14

Hello, I recently tried to build my system with libressl instead of openssl. In dovecot one issue that popped up was that libressl doesn't have the ECDH auto functions from openssl 1.0.2 beta versions. However as the #ifdef's in dovecot's code check for the openssl version and libressl's version numbers are higher the compilation fails there. Attached is a patch that will change that checks. Instead of checking for the version number it checks for the availability of the feature itself (by checking for the define of SSL_CTRL_SET_ECDH_AUTO). This should make this check more robust and work independently of the version number of the used openssl instance. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

BUG: Authentication client sent unknown handshake command
by Lukas Haase 22 Jul '14

22 Jul '14

Hi, Some time ago my dovecot started to become BUGgy: Evertime I restart the system, dovecot is started but I cannot login. I see the following information in the logs: Jul 4 04:04:36 mail dovecot: auth: passwd-file(user,127.11.91.218,<nfkQjFT9vwCADFra>): no passwd file: /etc/dovecot/imap.passwd Jul 4 04:04:36 mail dovecot: auth: Error: BUG: Authentication client sent unknown handshake command: REQUEST?1183186945?20438?1?a8c7241e7b0778f9f0125da760cd16fa Jul 4 04:04:36 mail dovecot: imap: Error: Authentication server didn't send valid SPID as expected: MECH#011PLAIN#011plaintext Jul 4 04:04:36 mail dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=20438 client-id=1) Jul 4 04:04:36 mail dovecot: imap-login: Internal login failure (pid=20438 id=1) (internal failure, 1 succesful auths): user=<user>, method=PLAIN, rip=127.11.91.218, lip=73.82.101.172, mpid=20439, TLS, session=<nfkQjFT9vwCADFra> It does not help to restart the client. But when I then restart the server service dovecot restart it works again. But this is very dangerous because the server might reboot and I might not immideately have the chance to restart dovecot manually. What's going on here? mail:/# uname -a Linux mail 2.6.32-openvz-042stab090.2-amd64 #1 SMP Sat Jun 21 00:22:42 MSK 2014 i686 GNU/Linux mail:/# dovecot --version 2.1.7 Thanks, Luke
