Dovecot pigeonhole help sought
by Timothy Murphy 29 Jul '14

29 Jul '14

I'm running postfix + dovecot + dovecot-pigeonhole on my CentOS-7 home server. I would like spam to finish up in ~/Maildir/.Spam/ . Spam is being marked, but is not separated - it ends up with all the other email in ~/Maildir/cur/ . Evidently there is some step I have omitted to take. I give the output of "sudo doveconf -n" below. The file ~/.dovecot.sieve reads: ------------------------------ # Sieve Filter require ["fileinto","regex","envelope","vacation"]; if header :contains "X-Spam-Flag" "YES" { fileinto "/home/tim/Maildir/.Spam/"; } ------------------------------ When I run "sudo systemctl restart dovecot" I see the line Jul 27 18:54:23 alfred dovecot: master: Dovecot v2.2.10 starting up for imap, pop3, lmtp, sieve (core dumps disabled) in /var/log/maillog Output of "sudo doveconf -n > dovecot.conf" ------------------------------ # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-123.4.4.el7.x86_64 x86_64 CentOS Linux release 7.0.1406 (Core) listen = * mail_debug = yes mail_location = maildir:~/Maildir 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 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 sieve ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" } ------------------------------ Any advice or suggestions gratefully received.

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.

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.

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.

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

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

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.

subfolders in public mailboxes
by Burak Arslan 21 Jul '14

21 Jul '14

Hello, I added this to the configuration: namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public subscriptions = no list = yes } and I can list maildirs inside these folders correctly. however, I can't see any subfolders. The issue seems to be that /var/mail/public dir itself is interpreted as a maildir directory. However, what I'd like to do is to have a bunch of directories inside /var/mail/public and treat them as separate maildirs. (I'd like to use this to make a few existing mailboxes public) is this possible? Best regards, Burak

Dovecot Replication: First Run
by Asai 19 Jul '14

19 Jul '14

Greetings, I'm working on building a redundant Dovecot server which will be replicated with my original. I would like to know if there's any potential problems I could run into in running this for the first time. For example, during an initial sync is it possible for the new server to sync improperly with the original and delete all of the emails on the original? Are there any gotchas that I should be aware of when doing a first run? -- --Asai

Difference btw. Dovecot Director and Dovecot Proxy
by Nathan Schultheiss 19 Jul '14

19 Jul '14

Hello, For a few days I try to understand what program (Dovecot Director or Dovecot Proxy) I should use for my email architecture. We are a hospital, and for security reasons, we must host ourselves our emails, and we must leave Google Apps... I wish to make a Dovecot backend for each department of the hospital. Each backend Dovecot has a local storage. Server 01: cardiology Server 02: emergency ... Server 05: administration Dovecot looks in the database which server to use to store email (lmtp) and transfer the mail for storage. I do not understand if I have to work with Dovecot Director or Proxy if I would that LMTP or IMAP request are forwarded to the right backend. Each have self storage and have not access to the other backend storage (no nfs, no network storage, ...). Users indicate imap.hospital.local, this point to Dovecot Director or Proxy and Dovecot check the login/password and forward the user to the right backend. In my database I put user@hospital = storage host 172.16.2.10 = folder /home/vmail/user/ (Maildir) I've read that the Director can refer the user to the same backend when there is a activ session (POP, IMAP, LMTP) But can we tell him to always refer the user to the same backend (IMAP and LMTP) ? I've found this picture schema who user have Dovecot Proxy => Dovecot Director => Dovecot Backend And I'm confused why they have proxy + director ?!? Can anyone tell me if I need to focus on Dovecot Director or Dovecot Proxy to create the architecture of this hospital ? My question is probably stupid for Dovecot sysadmin, but I'm lost in the WIKI :) Thanks in advance, Nathan

Postfix user@domain splitting
by Ricardo Branco 18 Jul '14

18 Jul '14

I have been trying looking though all the wiki documents to setup LMTP. It now seems to all be connected except that it keeps saying that the user is not recognised when postfix sends to LMTP, it sends the full recipent email address but seems that on the dovecot side it is unable to work with this. I have checked the userdb and made sure its using %n but alas it still does not work. Currently ive had to revert to using LDA as it works fine with that but i still dont know how as the postfix config variable $RECIPIENT is the full email address and does not seem to matter to LDA.

Dovecot/K9/Thunderbird IMAP interaction issues: replicated messages, constant reloading (TB) & missing new messages (K-9)
by David Gessel 18 Jul '14

18 Jul '14

Version Info: FreeBSD 9.2-RELEASE #0 r266046 AMD64, Dovecot 2.2.13, dovecot-pigeonhole-0.4.3, amavisd-new-2.8.0_2,1, clamav-0.98.4, postfix29-2.9.9_1,1, postfixadmin-2.3.6, spamassassin-3.4.0_12 (zpool data and output of dovecot -n at bottom of post) I suspect these are related problems and further that they are related to some trivial newb error I've made in my configuration, but searching descriptions of the symptoms has not yet guided me to a solution. I recently migrated from Courier to Dovecot on new hardware and imap synced a 16GB mailstore (du -hs) divided up into annual directories with about 15,000 messages each. I mention the size because it seems an errant Remove Duplicate Messages (Alternate) 0.3.9 acting on what seem to be false duplicates in Thunderbird reduced the inbox size from 7500-ish messages to 1300 (DOH!) and may have solved my K-9 problem described below. My old Courier server still has the vast majority of these messages and I will resync someday and then try to file them away more expediently than my previously somewhat lazy management style to keep the inbox small. * In thunderbird, I get constant downloading of messages. Every time I switch to the inbox from another folder, the messages start redownloading. This sometimes, but not always, seems to create duplicate messages, but I'm now fairly sure they are only created in the client and not on the server. Searching through various forums, it appears this has been a problem for Thunderbird for some time, but it wasn't for me on Courier. As posts about similar errors seem to have petered out over the last year without any clear guidance on how to fix it that I could find, I expect there's a simple fix I just haven't found yet, either in TB configuration or in Dovecot. Any hints? I tried Thunderfix to remove the .msf files and will be redownloading my mail over the thin pipe out to Iraq for the next 6 months (DOH!). One artifact is that when I restart thunderbird, my inbox is reported as having about 130 messages in it, then thunderbird starts redownloading headers and eventually gets back up to the 1297 currently listed both in the TB pane and by ls | wc -l in /cur. Is it possible there is a time out that needs to be extended? In TB, I've set (among other less apparently relevant options) mailnews.tcptimeout;1000 mail.db.idle_limit;30000000 * Also, with Thunderbird, I get duplication of messages in the client. I suspect this is related to the previous redownload error, but there is some indication in some posts that it is potentially related to a dirty flag. I've had this problem before with Thunderbird and Courier, but it went away after a TB update. It seems to have reappeared with Dovecot. The TB client hasn't been updated during the transition, so some interaction issue seems more likely than a pure TB bug. Likely TB's fault as this is a well known, but poorly diagnosed TB issue (deleting duplicates regularly seems to be the solution, but my inbox would double in size every few hours on the LAN. Now that I'm remote over a 2mbps link, it has slowed way down: bonus!). * "Expunged message reappeared, giving a new UID" errors appear a lot. This might well be related to the last error. This seems to happen with TB client connections, but I'm not sure what action triggers it. I am not replicating. I tried renaming 10-director.conf to 10-director.conf.disabled and got no complaints from Dovecot (as I'm not using replication, it shouldn't) but that indicates that this Expunged message reappeared error is probably of a different source than, for example, Simon Fraser's debug effort. * K9 was only showing a subset of my messages and generally not the new ones. They'd appear in the alert properly, but weren't visible in the client and sometimes they'd be visible and then disappear later. I imagined there could a correlation between TB checking mail and perhaps moving messages from /new to /cur and K9 losing track, but the potentially tragic "duplicate" removal may have reduced my inbox to a size that k9 can handle as K9 inbox display seems normal now as far as I can tell. When I resync (assuming I can), I sort of dread this problem reappearing. K9 worked as expected against Courier with the same inbox. These apparently difficult to diagnose problems are occasionally suggested as related to namespace configuration issues and thunderbird is reported to have issues with some separator options. I vaguely suspect this, but I'm pretty sure my namespace config is default and should be well tested. I haven't, for example, explicitly stated the default "/" but left it commented out. I increased the connection limit count per user*IP to 20 as TB seems to be parallel downloading a lot of folders. This has neither improved nor degraded performance in any way I can see and is probably irrelevant. Any hints greatly appreciated.

Sieve: adding Date: header when missing
by Daniele Nicolodi 17 Jul '14

17 Jul '14

Hello, there is a way with a sieve rule to add a Date: header when it is missing? Adding one with the time of reception of the message or using the date from the the first Received: header would be good options. Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically. Thanks. Cheers, Daniele

If local Dovecot stops working, check lo
by Steve Litt 17 Jul '14

17 Jul '14

Hi all, You probably know this already, but just in case... Let's say you have your email client getting mail from a Dovecot server on the same computer (which is a really good way of doing things, by the way). Then one day your email client starts saying "connection refused" after a suitably long timeout. So then, to find out where things are getting stuck, you do the following command: openssl s_client -connect 127.0.0.1:993 -quiet And you don't even get an OK back. This means it's not your username or password, because you never even got that far. Before spending a lot of time doing diagnostic tests and narrowing it to the root cause, try this as root: ifdown lo ifup lo A malfunctioning lo will cause Dovecot not to connect to clients. My experience with Debian Wheezy is that lo "goes down" a lot, so this is one of the first things I do when odd stuff happens.

Resource Temporarily Unavailable on replicator-doveadm
by Cassidy Larson 16 Jul '14

16 Jul '14

We're running 2.2.13 on two servers with replication. Still trying to get my replication tweaked correctly and I’m noticing a bunch of these errors for the same users over and over again: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable The 5-7 that I see all have quite a number of individual mailboxes (20+), I’m wondering if that has something to do with it? Also, my replicator status for full resync requests has been hovering around 2300-2400 the last few days: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 2410 Waiting 'failed' requests 1 Total number of known users 9836 In checking the replication status for some of the “Resource temporarily unavailable” list from above, if I run it multiple times it outputs different results for the fast and full sync time: # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:21 49:43:34 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:55 00:10:55 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:56 00:10:56 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:57 00:10:57 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:24 49:43:37 - doveconf output for the replicator service is: service replicator { process_limit = 10 process_min_avail = 2 unix_listener replicator-doveadm { group = mailsys mode = 0666 user = mailsys } unix_listener replicator { group = mailsys mode = 0666 user = mailsys } } Anybody have any clues or suggestions? I’d be much appreciative. Thanks, Cassidy

Sending emails using dovecot auth
by Murray Trainer 16 Jul '14

16 Jul '14

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray

Dovecot2 Antispam MAILTRAIN backend with SpamAssassin
by Mohammad S. Babaei 15 Jul '14

15 Jul '14

Hi there, I've already asked this question on FreeBSD forums without getting any response. So, I thought it's a good idea to ask it again here. I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10 VPS and it works flawlessly. Though, I couldn't setup the Dovecot Antispam plugin to train SpamAssassin when I move mails to the Junk folder. I installed the plugin from FreeBSD ports and followed the official documentation [1] and the man page [2] without any success.
