Why does Dovecot authentication against Openldap fail when using TLS encryption?
by Dimitri KOPRIWA 29 Jun '17

29 Jun '17

Dear Mailing list, I have a Dovecot v2.2.9 server that authenticate against a Openldap server. I want to configure Dovecot to use TLS for LDAP authentication. I have tried to fetch/send emails using Thunderbird: - IMAP succeed to fetch mail - SMTP failed to send mail The Dovecot server produce the following log : Jun 29 08:44:00 mail postfix/submission/smtpd[634]: connect from virtual.domain.com[172.16.0.1] Jun 29 08:44:01 mail dovecot: auth: Debug: auth client connected (pid=0) Jun 29 08:44:02 mail dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=smtp#011nologin#011lip=172.17.0.15#011rip=172.16.0.1#011secured#011resp=<hidden> Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): bind search: base=dc=mail,dc=domain,dc=com filter=(&(objectClass=CourierMailAccount)(mail=me(a)domain.com)) Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): no fields returned by the server Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): result: uid missing Jun 29 08:44:02 mail dovecot: auth: Debug: client passdb out: OK#0111#011user=me(a)domain.com Jun 29 08:44:04 mail postfix/submission/smtpd[661]: connect from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:04 mail postfix/submission/smtpd[661]: lost connection after CONNECT from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:04 mail postfix/submission/smtpd[661]: disconnect from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:07 mail dovecot: auth: Debug: auth client connected (pid=662) Jun 29 08:44:07 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=172.16.0.2, lip=172.17.0.15, TLS handshaking: Disconnected, session=<MGK6TRVTRACsEAAC> **Note that before I switch to use TLS**, the server was doing clear connection to Openldap and the **binding was working fine**.

localhost logins
by Daniel Miller 27 Jun '17

27 Jun '17

While auditing my logs after an account was compromised, I see a number of entries like: Jun 23 11:32:18 bubba dovecot: auth: ldap("one-of-my-accounts",127.0.0.1): invalid credentials I'm trying to figure out where this login attempt is coming from. I do run ASSP (an SMTP proxy) on this server, as well as Postfix - but I wouldn't think there'd be any communication with Dovecot for those? Postfix does use Dovecot SASL - but I see separate log entries for Postfix authentication failures. There are of course plenty of external IP's listed in Dovecot logs - I'm just asking for possible causes for the localhost entries. -- Daniel

Released Pigeonhole v0.4.19 for Dovecot v2.2.31.
by Stephan Bosch 26 Jun '17

26 Jun '17

Hello Dovecot users, Here's the definitive 0.4.19 release. There is one additional fix. Changelog v0.4.19: * This release adjusts Pigeonhole to several changes in the Dovecot API, making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole will produce compile warnings with the recent Dovecot releases (but still work ok). - Fixed bug in handling of implicit keep in some cases. Implicit side-effects, such as assigned flags, were not always applied correctly. This is in essence a very old bug, but it was exposed by recent changes. - include extension: Fixed segfault that (sometimes) occurred when the global script location was left unconfigured. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.19.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.19.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

https://dovecot.org/releases/2.2/dovecot-2.2.31.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.31.tar.gz.sig This should be a great and stable release for the summer :) v2.2.32 is planned for the end of August. Hopefully soon afterwards we can get back to v2.3. * LMTP: Removed "(Dovecot)" from added Received headers. Some installations want to hide it, and there's not really any good reason for anyone to have it. + Add ssl_alt_cert and ssl_alt_key settings to add support for having both RSA and ECDSA certificates. + dsync/imapc, pop3-migration plugin: Strip trailing whitespace from headers when matching mails. This helps with migrations from Zimbra. + acl: Add acl_globals_only setting to disable looking up per-mailbox dovecot-acl files. + Parse invalid message addresses better. This mainly affects the generated IMAP ENVELOPE replies. - v2.2.30 wasn't fixing corrupted dovecot.index.cache files properly. It could have deleted wrong mail's cache or assert-crashed. - v2.2.30 mail-crypt-acl plugin was assert-crashing - v2.2.30 welcome plugin wasn't working - Various fixes to handling mailbox listing. Especially related to handling nonexistent autocreated/autosubscribed mailboxes and ACLs. - Global ACL file was parsed as if it was local ACL file. This caused some of the ACL rule interactions to not work exactly as intended. - auth: forward_* fields didn't work properly: Only the first forward field was working, and only if the first passdb lookup succeeded. - Using mail_sort_max_read_count sometimes caused "Broken sort-* indexes, resetting" errors. - Using mail_sort_max_read_count may have caused very high CPU usage. - Message address parsing could have crashed on invalid input. - imapc_features=fetch-headers wasn't always working correctly and caused the full header to be fetched. - imapc: Various bugfixes related to connection failure handling. - quota=imapc sent unnecessary FETCH RFC822.SIZE to server when expunging mails. - quota=count: quota_warning = -storage=.. was never executed - quota=count: Add support for "ns" parameter - dsync: Fix incremental syncing for mails that don't have Date or Message-ID headers. - imap: Fix hang when client sends pipelined SEARCH + EXPUNGE/CLOSE/LOGOUT. - oauth2: Token validation didn't accept empty server responses. - imap: NOTIFY command has been almost completely broken since the beginning.

ACL problems on shared folder
by Thomas Robers 26 Jun '17

26 Jun '17

Hello, I've a Dovecot Server Version 2.2.30.2 running on CentOS 6.9 and there's a problem with acls on shared folder. We have some mailboxes which are shared and used as a "group mailbox" and also some user who share their inbox and only the inbox when they are on holiday e.g.. When I set "acl_defaults_from_inbox = yes" it's not possible to restrict the access to only the inbox, meaning that the user who wants to share only their inbox have to share the whole mailbox. On the other hand when I set "acl_defaults_from_inbox = no" it is not possible to create a folder direct under the inbox of a "group mailbox" and one gets a "permission denied" message. Is this the normal behavior normal? Although the user who wants to create the folder has all rights he gets a "permission denied" message? Why? Am I missing something important? Does anyone who uses shared mailboxes had the same problem and solved this? Any suggestion or information, that I probably miss is welcome.

Courier migration to dovecot
by j.emerlik 23 Jun '17

23 Jun '17

Hi, I'm almost ready to migrate Courier to Dovecot 2.2.31 but I have one question about home and mail directory. It's good idea to have same directory form home and mail ? Which scenerio will be better and why ? For example: A) Home: /home/doamin/user1 Mail: /home/doamin/user1 B) Home: /home/doamin/user1/home Mail: /home/doamin/user1 C) Home: /home/doamin/user1/ Mail: /home/doamin/user1/mail Thanks & regards, Jack

Issue with dsync server - copy transaction record copying to wrong destination mailbox.
by Ivan Warren 22 Jun '17

22 Jun '17

Hello all, I am encountering the following issue : I have 2 dovecot servers with 2 way replication. Everything works fine except for one specific issue : When my MUA (thunderbird) filters (junk & manual) refile a mail from my inbox, I then sometimes find multiple copies of the original message in the destination folder. I have seen the following log entries which make me think (but I'm new to this) that there could be an issue with the processing of the COPY transaction record during DSYNC : * TB Marking msg as Junk Jun 22 20:36:14 db04 dovecot: imap(ivan): flag_change: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * TB Copies msg to Junk Mailbox Jun 22 20:36:14 db04 dovecot: imap(ivan): copy from INBOX: box=Junk, uid=32059, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * TB expunges mail from INBOX Jun 22 20:36:14 db04 dovecot: imap(ivan): expunge: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Local server receives transaction from remote server and saves message again to INBOX Jun 22 20:36:16 db04 dovecot: dsync-local(ivan): save: box=INBOX, uid=502903, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Remote server copies message from INBOX to INBOX <<<<<<<<<<<<<< That's my issue Jun 22 20:36:16 db04 dovecot: doveadm: Error: dsync-remote(ivan): Info: copy from INBOX: box=INBOX, uid=502903, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Remote server expunges msg copy Jun 22 20:36:16 db04 dovecot: doveadm: Error: dsync-remote(ivan): Info: expunge: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 Is this a known issue (I may not have looked deep enough..) ? Is more information needed ? (note again that for me dovecot is working perfectly fine except for that little issue). (Version is 2.2.27 from Debian stretch) Thanks, --Ivan

Released Pigeonhole v0.4.19.rc1 for Dovecot v2.2.31.rc1.
by Stephan Bosch 22 Jun '17

22 Jun '17

Hello Dovecot users, This small release is mainly about adjusting to changes in the Dovecot API. There is one significant fix. Changelog v0.4.19: * This release adjusts Pigeonhole to several changes in the Dovecot API, making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole will produce compile warnings with the recent Dovecot releases (but still work ok). - Fixed bug in handling of implicit keep in some cases. Implicit side-effects, such as assigned flags, were not always applied correctly. This is in essence a very old bug, but it was exposed by recent changes. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.19… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.19… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

+vnd.dovecot.duplicate for Bogofilter duplication shortcomings
by Luescher Claude 21 Jun '17

21 Jun '17

Hello, Sorry for a bit offtopic but it seems the bogofilter community is just as dead as dspam is. I trying to switch from DSPAM to bogofilter on a server where if I turn bogofilter on I run into the following issue: Certain users have sender and recipient bcc maps setup in postfix. This is for forwarding copy of an email to other address for example: Incoming lclude(a)company.com -> info(a)company.com Outgoing lclude(a)company.com -> info(a)company.com This way whatever lcalude sends or receives a copy will be sent to the info mailbox. When bogofilter is enabled the bcc recipient (info) receives a dupe of every email. Did anybody run into this? virtual_destination_recipient_limit = 1 dspam_destination_recipient_limit = 1 was a working fix for me for the old system, however bogofilter_destination_recipient_limit = 1 does not work in this case so if this issue is not possible to fix by configuration an alternate solution like making dovecot delete duplicate messages by message ID would be a viable option. I have +vnd.dovecot.duplicate plugin enabled but it seems to be ineffective. Any other tips for a workaround? Thank you. Claude

dovecot & cap_net_admin capability
by Michal Hlavinka 21 Jun '17

21 Jun '17

Hi, we've seen SELinux reports from our users that dovecot tried to use something that needs CAP_NET_ADMIN capability. Before enabling it, we would like to know where it originated from. I've checked the sources, but was not able to find anything that would require this capability. Do you know for what it is used? CAP_NET_ADMIN Perform various network-related operations: * interface configuration; * administration of IP firewall, masquerading, and accounting; * modify routing tables; * bind to any address for transparent proxying "IP_TRANSPARENT"; * set type-of-service (TOS) "IP_TOS" * clear driver statistics; * set promiscuous mode; * enabling multicasting; * use setsockopt(2) to set the following socket options: SO_DEBUG, SO_MARK, SO_PRIORITY (for a priority outside the range 0 to 6),SO_RCVBUFFORCE, and SO_SNDBUFFORCE Cheers, Michal Hlavinka

Thunderbird "Empty Trash" causes inconsistent IMAP session state?
by awl1 20 Jun '17

20 Jun '17

All, having successfully compiled and set up Dovecot 2.2.29.1 on my Thecus NAS as a newbie without any further hassle, and already imported an external mail archive of ~15 GB into a lz4-compressed mdbox (with impressive performance on the old Intel Atom CPU!), I stumbled into a minor, but reproducible issue that might well be already known, but I haven't managed to find any pointers through Google search: When I *manually empty the Trash folder from Thunderbird* (52.1.1, regardless of Windows or Linux client) by right-clicking on a non-empty Trash folder and then selecting "Empty trash", Dovecot produces the following log message, and I need to restart Thunderbird client in order to properly refresh its folder status: May 30 23:42:04 imap(xxx(a)xxx.org): Info: *IMAP session state is inconsistent, please relogin.* in=405 out=3114 Is this behaviour and message intended, or did I indeed run into a bug here? Many thanks & best regards Andreas

Show other users quota
by Kristjan Eentsalu 19 Jun '17

19 Jun '17

Hey, Is there a way to show other users quota under shared namespace? Right now when I try to "a getquotaroot user/other.user" I get "NO Not showing other users' quota" Dovecot version 2.2.27 Relevant part of the config: namespace user { list = children location = maildir:%%h/Maildir:LAYOUT=fs:DIRNAME=iiuuuuiiiuuu:INDEXPVT=%h/shared/%%n prefix = user/%%n/ separator = / subscriptions = no type = shared } Kristjan

Have you checked whether the dovecot user can traverse all the way from / to /u2/usermail/luser/ > I've (rm ~/mail/.subscriptions && touch ~/mail/.subscriptions) to flush any > subscriptions file issues. I'm thinking no .subscription would be better. > Is there a subtle interaction with mail_full_filesystem_access settings, or > similar that might be getting in the way? Dovecot does have chroot-ing stuff that might impede symlink following: https://wiki.dovecot.org/Chrooting > Other data: there are fs quotas on / but not /u2. That shouldn't matter, but > I will concede that I'm not a little ignorant about such things. It seems you have more basic file access problems. > How might I go about further debugging this? I've tried to manually doveadm > index those mailboxes, which doesn't give me any errors, but it also returns > far too quickly to give me the impression that it's done anything. Same result. Nothing with verbose logging (set mail_debug = yes)? Try the simple case ln -s /u2/usermail/luser/OLD_INBOX/INBOX_2016_01_to_08 ~luser/mail/testbox then $ telnet localhost 10143 x0 login luser *** x1 SELECT testbox What do you get here and in your logs? If this doesn't produce any usable diagnostics, I would pull out the heavy duty process trace tool and trace the imap process to figure out what it's really doing and where it's failing.

Fortunately, it just involves reformatting the data and a little reconmfiguration of dovcot. If you can find the tool and disk space, it's well worth doing. Of course, when running a proverbial dinosaur, you're often more preoccupied with preventing the next proverbial meteorite strike. > What I meant was, are certain types of filenames "blocked" by policy from > being created via IMAP commands?

I never saw anything that could do that -- maybe you can torture the virtual mailbox facility to get that done. If all your concerned is dovecot dot-files, you can place the indices somewhere else other than the user's filesapace. > One last problem area is that many users have soft-links to mailboxes > located on a second drive, but these never appear in folder enumeration > lists or they appear grayed out in SeaMonkey/Thunderbird.

It works for me. From what I see, the ownership of the symlink is ignored; it's the underlying file that counts. Maybe a subscription issue? Joseph Tam <jtam.home(a)gmail.com>

You can disable dotclock altogether, but I don't think this is what you meant. You can use locking method "dotlock_try" rather than "dotlock" -- the former will ignore quota/permissions problems and plow on. (It still logs it.) You could also align luser's mail folder group with with luser's GID, which is usually what I do. Maybe locks are created even when files don't exist as there may be a race condition where another process is creating/deleting it at the same time. Joseph Tam <jtam.home(a)gmail.com>

v2.2.30 released
by Timo Sirainen 13 Jun '17

13 Jun '17

https://dovecot.org/releases/2.2/dovecot-2.2.30.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.30.tar.gz.sig * 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 - IMAP NOTIFY wasn't working for non-INBOX if IMAP client hadn't enabled modseq tracking via CONDSTORE/QRESYNC. - fts-lucene: Fix it to work again with mbox format - Some internal error messages may have contained garbage in v2.2.29 - mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys are used. Otherwise the copied mails can't be opened. - vpopmail: Fix compiling

rescann / reindex / rebuild a subfolder structure
by Götz Reinicke - IT Koordinator 13 Jun '17

13 Jun '17

Hi, an user is missing all mail from a folder and all subfolders which are still saved in the users maildir directory on the dovecot server. From an imap client she sees the main folder but empty. No subfolders. She told me with an other imap client and a new created account she has the same problem. Question: Can I resync / regenerate some folder... index.... something....-files from the dovecot side? Thanks for hints and regards . Götz

This is a consequence of writing secure software: it employs least privilege so that a fault will not result in someone being able to mess around with someone else's mail (or indices). GID can also govern access to shared mailboxes. Joseph Tam <jtam.home(a)gmail.com>

service(auth): command startup failed?
by HL1234 12 Jun '17

12 Jun '17

Hello, I need help because since some days I can not figure out what error this is and where it come from. I have used dovecot since years. Know after an update it is broken. First I like to give you some data: It's a FreeBSD 11.0 Server with sendmail (SMTP) and dovecot for IMAP with SSL. #dovecot --build-options Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw fail SQL drivers: mysql Passdb: checkpassword ldap pam passwd passwd-file sql Userdb: checkpassword ldap nss passwd prefetch passwd-file sql #dovecot --version 2.2.30.2 (c0c463e) I install the update with the FreeBSD ports. Before the update all was running fine. The state know is: form my client Outlook I can send eMail above SMTP. When I try to get my eMails by the IMAP-Server it is blocked. I have look around in the config files but I see nothing what has could be changed. I have tried to make new *.pem files with using the script in /usr/local/share/examples/dovecot/ but this havn't bring a solution. I need help for this error i see in the logs: dovecot.log master: Error: service(auth): command startup failed, throttling for 2 secs auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address ..... dovecot-info.log imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=77.178.105.78, lip=88.74.25.120, TLS Jun 12 23:01:15 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 8 secs): user=<>, rip=58.218.194.81, lip=88.74.25.120, TLS handshaking .... dovecot-debug.log imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth auth: Debug: Module loaded: /usr/local/lib/dovecot/auth/lib20_auth_var_expand_crypt.so auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Have anyone an idea what is going wrong and how to fix it?

We alse have same problem, now we are running Dovecot 2.2.30.2 and also use Dovecot SASL for SMTP authentication (postfix 2.11). We need to save all failed login attempts to database as source IP address, username and date and time but post-login script can do this but only after successful login. Failed login attempts information may be useful in the fight with bruteforce attacks. It's possible to execude some script after failed login ("Password mismatch") ? Regards, Jacek

namespace and folders
by Gregory Sloop 12 Jun '17

12 Jun '17

Using mbox format and this namespace namespace { inbox = yes hidden = yes prefix = INBOX/ } [Though I've also tried, seemingly, a million different namespace options to "fix" my problem.] It's a migrated setup from a 1.x dovecot install from Ubuntu 12.04, now on 16.04 The problem is in TBird [I haven't tested with any other mail clients] and IMAP; with that name-space I get all the folders both at the root level [same as inbox], as well as below inbox. [The same folders, pointing at the same underlying messages.] For example, if there's a folder "blah" and I subscribe to it, "blah" shows both at the same level as inbox, as well as a sub-item of inbox. If I unsubscribe from folder "blah" it also unsubscribes from the subfolder "blah" under inbox, and at the root level. [I hope that's clear enough...] This is not a terrible problem, but it's cosmetically ugly and confusing for users. I'd prefer to only see these folders as subscribed as sub-folders [or sub-items] under inbox. I'd guess I'm making some stupid beginner error, but I've not been able to figure it out, as of yet. Any help would be greatly appreciated. -Greg

doveadm ssl error when upgrading from 2.2.27 to 2.2.29
by Pallissard, Matthew 12 Jun '17

12 Jun '17

I'm starting to see the following error when upgrading from 2.2.27 to 2.2.29. doveadm(ip.add.re.ss): Error: doveadm client disconnected before handshake: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher Downgrading from 2.2.27 resolves, error still persists in 2.2.28. I'm using openssl 1.1.0.f and an ec cert/key with the following curve. ASN1 OID: prime256v1 NIST CURVE: P-256 Does anyone know anything about this off the top of their head? If not I'll try to git-bisect 2.2.27 -> 2.2.28 and see if I can find any offending commits later on this week. -- Matt Pallissard

AIX lacks getopt_long

Changing the name of a compressed file
by Peter West 11 Jun '17

11 Jun '17

Concerning Maildir, the wiki page on compression has this: All mails must have ,S=<size> in their filename where <size> contains the original uncompressed mail size, otherwise there will be problems with quota calculation as well as other potential random failures. Note that if the filename doesn’t contain the ,S=<size> before compression, adding it afterwards changes the base filename and thus the message UID. The safest thing to do is simply to not compress such files. Further down on the same page is this: If the file does exist, rename() (mv) the compressed file over the original file. • Dovecot can now read the file, but to avoid compressing it again on the next run, you'll probably want to rename it again to include e.g. a "Z" flag in the file name to mark that it was compressed (e.g. 1223212411.M907959P17184.host,S=3271:2,SZ). These comments seem to contradict each. Or is there a difference between adding the size specifier to the filename and adding a Z flag to the end of the file name? -- Peter West pbw(a)pbw.id.au And the great throng heard him gladly.

Pacaging/build issues with AIX and vac (dovecot-2.2.25)
by Michael Felt 10 Jun '17

10 Jun '17

Hi. I finally decided it was really time to stop being lazy and really move away from gmail. After I have a server in my basement using power, etc. So I turned on the imap provided - and did not quite cry - it will have to do for now, but imap2 is wanting. A real server yes, but not Linux. (Using linux would require another server AND I would feel I am being lazy again). So, I downloaded dovecot-2.2.25 and tried to build.

v2.2.30.1 released
by Timo Sirainen 09 Jun '17

09 Jun '17

https://dovecot.org/releases/2.2/dovecot-2.2.30.1.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.30.1.tar.gz.sig Due to some release process changes I didn't notice that one important bugfix wasn't included in the v2.2.30 release branch before I made the release. So fixing it here with v2.2.30.1. Also included another less important fix. - quota_warning scripts weren't working in v2.2.30 - vpopmail still wasn't compiling Also I guess should mention that in v2.2.30+ the "script" service's protocol changed to a new version. If anyone had written their own script services (not using the included "script" binary) they would need some changes. I haven't heard of anyone having done that though.

[Dovecot] Dovecot stops with "Fatal: kevent(): Invalid argument"

# 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-STABLE amd64 Dovecot stops with the following logged: - master: Fatal: kevent(): Invalid argument I have found that a diff was created for "src/lib/ioloop-kqueue.c" for a similar issue: http://dovecot.org/pipermail/dovecot/2010-November/054855.html I have patched my system with this and haven't seen the problem since, but I don't know if this is a coincidence. Could you please explain if the diff should actually fix anything or just add some more logging in case it stops again? Best regards Henrik Larsson

Dovecot LDAP using custom field to allow users to connect
by Michael JOIGNY 09 Jun '17

09 Jun '17

Hi all, I'd like to know if it's possible to add a custom field when the authentification is made by users. My boolean custom field will be for example "AllowUser" (false/true). I'm trying to do something like that but it's not working : /user_filter = (&(objectClass=posixAccount)(uid=%u)(objectClass=myclass)(AllowUser=TRUE))/ This is my dovecot/ldap configuration below : /*# dovecot.conf* / /passdb {// // driver = ldap// // args = /etc/dovecot/dovecot-ldap.conf// //}/ *# dovecot-ldap.conf* /hosts = myurl:myport// //dn = cn=myuser,dc=mydomain,dc=com// //dnpass = ********// //a//uth_bind = yes// //auth_bind_userdn = uid=%u,ou=users,dc=mydomain,dc=com// //ldap_version = 3// //base = ou=Users,dc=mydomain,dc=com// //scope = base// //default_pass_scheme = SSHA512 / Do you have an idead ? Kind regards. -- Michael

lmtp: Error: Temp file creation to /tmp/ ... failed: No such file or directory on incoming mails with attachments
by Lars-Sören Steck 09 Jun '17

09 Jun '17

Dear list, I'm currently facing problems when receiving eMails with attachments, at least sometimes. My mailserver is set up with the tool 'Mailcow', and hence is based on Dovecot (2.2.22 (fe789d2)) and Postfix. Usually, there are no problems with receiving mails. If a mail has an attachment, however, it is possible that the following error occurs (extract from /var/log/mail.log): 'Jun 7 12:50:28 mail postfix/lmtp[26827]: 564E68A0515: to=<abc(a)def.ghj>, relay=my.mail.server[private/dovecot-lmtp], delay=0.71, delays=0.67/0.01/0.01/0.02, dsn=4.3.0, status=deferred (host my.mail.server[private/dovecot-lmtp] said: 451 4.3.0 Temporary internal failure (in reply to end of DATA command))' Extract from /var/log/mail.err: 'Jun 7 12:50:28 mail dovecot: lmtp(26828): Error: Temp file creation to /tmp/dovecot.lmtp.mail.26828. failed: No such file or directory' Once this happened the first time after dovecot is running, it will happen for all incoming mails with attachments. This can be solved temporarily by restarting the dovecot service and running postqueue -f, but that obviously does not solve the underlying problem. In this post to this list, it is stated that dovecot sometimes creates temp files to avoid 'excessive memory usage'. I'm guessing that this is the case here, also the error message is similiar: https://dovecot.org/list/dovecot/2016-June/104722.html Should I simply change the configuration variable mail_temp_dir to solve this? Why is dovecot not able to find the /tmp folder? In the list thread, it is stated that this is caused by dovecot running with enabled chrooting. As far as I understand it though (correct me if I'm wrong), chrooting is not enabled in my dovecot configuration. Please find attached the output of 'dovecot -n': # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-78-generic x86_64 Ubuntu 16.04.2 LTS auth_mechanisms = plain login dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf } listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k mail_home = /var/vmail/%d/%n mail_location = maildir:~/ mail_max_userip_connections = 500 mail_plugins = quota acl fts fts_solr 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 index ihave duplicate mime foreverypart extracttext namespace { list = yes location = maildir:%%h/:INDEXPVT=~/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Archiv { special_use = \Archive } mailbox Archive { auto = subscribe special_use = \Archive } mailbox Archives { special_use = \Archive } mailbox "Deleted Messages" { special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Entwürfe { special_use = \Drafts } mailbox "Gelöschte Objekte" { special_use = \Trash } mailbox Gesendet { special_use = \Sent } mailbox "Gesendete Objekte" { special_use = \Sent } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Papierkorb { special_use = \Trash } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/var/vmail/shared-mailboxes.db fts = solr fts_autoindex = yes fts_solr = url=http://127.0.0.1:8983/solr/ quota = dict:Userquota::proxy::sqlquota quota_rule2 = Trash:storage=+100%% sieve = /var/vmail/sieve/%u.sieve sieve_after = /var/vmail/sieve/global.sieve sieve_max_script_size = 1M sieve_quota_max_scripts = 0 sieve_quota_max_storage = 0 } protocols = imap sieve lmtp pop3 service auth { unix_listener /var/spool/postfix/private/auth_dovecot { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } unix_listener auth-userdb { mode = 0600 user = vmail } user = root } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 2 service_count = 1 vsz_limit = 128 M } service managesieve { process_limit = 256 } ssl_cert = </etc/ssl/mail/mail.crt ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/mail/mail.key ssl_protocols = !SSLv3 !SSLv2 userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota imap_acl acl fts fts_solr } protocol lmtp { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota sieve acl fts fts_solr postmaster_address = postmaster(a)steck.cc } protocol sieve { managesieve_logout_format = bytes=%i/%o } remote 127.0.0.1 { disable_plaintext_auth = no } Thank you for your help.

mail storage auto detection failed?
by Alef Veld 08 Jun '17

08 Jun '17

Hi everyone. Nice to meet you. I’m new to dovecot and i came across a problem it seems. I setup a new user called sales with useradd, and gave it a password. Although it has a home directory, i set login to /sbin/nologin. When logging into the pop server on port 110 (with telnet) i get this in the logs: dovecot: pop3-login: Login: user=<sales>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=12938, secured, session=<94SotWVRoAB/AAAB> Jun 7 21:49:24 www dovecot: pop3(sales): Error: user sales: Initialization failed: Namespace '': Mail storage autodetection failed with home=/home/sales Jun 7 21:49:24 www dovecot: pop3(sales): Error: Invalid user settings. Refer to server log for more information. Did i have to initialise the mailbox in the homedirectory? What did i forget. I didn't change anything to the default dovecot.conf, i just installed the package with yum install dovecot (so latest version). This error also shows up when logging into port 143. Thanks for your help. My dovecot -n output if that helps is : [ec2-user@www log]$ dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 4.9.20-10.30.amzn1.x86_64 x86_64 mbox_write_locks = fcntl namespace inbox { inbox = yes location = prefix = } passdb { driver = pam } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { driver = passwd } Thanks a lot. -atv

For testing i login to imap like this "openssl s_client -connect localhost:993" and sometimes i get this message "* OK Waiting for authentication master process to respond..". I saw at other people, one of the problem was because they didn't disabled pam authentication when using another backend (like ldap or sql), but i already did that. Does anyone know what could cause such long login times and how to fix it?

Which allowed services can be defined (imap, pop3, etc.)
by Malte Schmidt 08 Jun '17

08 Jun '17

Hello, I am using Dovecot with an LDAP-backend for authentication. According to the documentation at https://wiki.dovecot.org/Authentication/RestrictAccess with LDAP and "pass_filter" it is possible to filter allowed services for the user with: pass_filter = (&(objectClass=posixAccount)(uid=%u)(service=%s)) Thats pretty cool. Now, in the LDAP-settings I created corresponding fields (service) and added the allowed services to tthese fields (imap, pop3, etc.). After that change, certain services were not available to that user anymore. So it seems that more services are there and after explicitly setting the services which are allowed, the other, not mentioned services stop to work. Now two questions: Is there any documented, full-featured list of the services that can be added? Is it possible to "flip" that setting so its not allowing certain services but denying the ones that are added to the "service"-fields? Cheers

virtual isp address, local delivery
by Hugh Bragg 07 Jun '17

07 Jun '17

I'm trying to understand how to deliver mail to an address locally which is popped from my isps email account. I access and keep these emails backed up on dovecot and use postfix smtp to deliver mail. The problem is that while fetchmail uses dovecot lda directly, postfix can't include my isps domain in its $mydestination because I won't be able to send mail to other users in that domain. I want to be able to send mail to other users I'm popping for in that domain, or even send myself mail. Currently postfix just relays the mail to the isp and it returns through fetchmail, but I'd like to have it delivered locally and still be able to email my isp users that I don't pop. As far as I can tell, this can't be done because virtual users have to be in postfix $mydestination. Does someone have a better setup they can share or know how to do this? Hugh

doveadm sync SSL error when upgrading from 2.2.27 -> 2.2.29
by Pallissard, Matthew 07 Jun '17

07 Jun '17

I'm starting to see the following error from doveadm when upgrading from 2.2.27 to 2.2.29. > doveadm(ip.add.re.ss): Error: doveadm client disconnected before handshake: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher I'm using a cert/key with the following curve. ASN1 OID: prime256v1 NIST CURVE: P-256 Downgrading to 2.2.27 resolves the issue. Does anyone know about this off the top of their head? If not I'll try to git-bisect 2.2.27->2.2.28 for any offending commits later on this week. -- Matt Pallissard

Multiuser attachment storage (mail_attachment_dir)
by megaone＠yandex.ru 06 Jun '17

06 Jun '17

Was trying to set up attachment storage, but folders are receiving permission only for current user, so if another user is receiving a mail with same attachment he is getting permission denied error on reading hash file. Is it possible to setup global attachment storage to work with all users, at least in domain? mail_access_groups won't help, as folders are given 0 group permission. Umask and setfacl won't help either.

Two domains - same user names filter
by Sandbox 06 Jun '17

06 Jun '17

Hi, I have two LDAP domains, which has some equal users, eg: abc(a)domain1.com abc(a)domain2.com I sat up this config: domain1 users maildirs are stored in /home/vmail/username domain2 users maildirs are stored in /home/vmail/domain2/username This works fine except one thing: i cant set up the ldap query to choose the correct maildir if the user names are equal. Is it possible to use a user_filter which will choose the correct maildir and user/domain from the email address? My current ldap.conf for domain1: hosts = ldap.domain1.com base = ou=People,dc=domain1,dc=com ldap_version = 3 user_attrs = uid=user user_filter = (uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 and for domain2: hosts = ldap.domain2.com base = ou=People,dc=domain2,dc=com ldap_version = 3 user_attrs = \ =mail=maildir:/home/vmail/%{ldap:departmentNumber)/%n/Maildir user_filter = (uid=%n) pass_attrs = uid=%n,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 Thanks, Robert

vnd.dovecot.pipe in sieve: what user....
by Larry Rosenman 06 Jun '17

06 Jun '17

I have a site-wide bayes database, that currently gets populated by scripts running as a user that is also the user that Exim uses to call spamd. When a script is running from the vnd.dovecot.pipe call, what user is it running as? Would a setuid script work? -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: larryrtx(a)gmail.com US Mail: 17716 Limpia Crk, Round Rock, TX 78664-7281

corrupted indexes rebuilding over and over
by micah 05 Jun '17

05 Jun '17

Hi, On saturday one of our dovecot machines had an OOPS, and we had to powercycle it. When it came up, it did a filesystem fsck (ext4) and fixed a couple things, but nothing in lost+found. Now, about 50 users have a problem where their indexes are corrupted. Dovecot tries to fix them, but for some reason it is failing. The users are seeing their mails duplicated and they cannot delete mails. I can see in the logs dovecot detecting this and trying to rebuild operations during delivery and imap login, but its repeating over and over and over. For one user, I've seen more than 4k lines in the logs about this. If i try to do doveadm force-resync -u username INBOX I get this: doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,383536) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: rebuilding indexes doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,384024) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index but then if i do it again, I get the same thing, over and over and over (the numbers change a little). This is dovecot 2.2.27 with mdbox format.... what can I do to fix this? Its driving users mad, and they keep going over quota as their space fills. thanks! micah

Possible RENAME bug
by Gabriele Bulfon 05 Jun '17

05 Jun '17

Hello, I'm having some trouble working on a webapp managing the imap tree on Dovecot. The same doesn't happen on other imap servers (e.g. Cyrus). Looks like if I receive shared folders from another user, and try to rename a folder in it, the rename command returns "ok", then if you list the new folder name, it isn't there. Looks like you've lost all the original folder because if you try listing the parent folder, you don't have nor the original nor the new name, even trying to logout/disconnect and reconnect/login. Luckily nothing is lost actually, if you try to create a new folder on the parent folder, and then list the parent folder, you get both the newly created one and the renamed one also appears magically! Here is the IMAP trace to reproduce: *** ON ACCOUN RECEIVING SHARED FOLDER *** PREPARE A FOLDER IN SHARED TREE WITH JUST ONE CHILD "aaaa" *** THEN RENAME aaaa FOLDER TO bbbb *** AFTER "OK Rename" FOLDER IS NOT PRESENT IN LIST A3 LIST "" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa * LIST (\HasNoChildren) "/" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa A3 OK List completed.

Retrieving mail from read-only mdbox
by Mark Moseley 05 Jun '17

05 Jun '17

This is a 'has anyone run into this and solved it' post. And yes, I've been reading and re-reading TFM but without luck. The background is that I'm working on tooling before we start a mass maildir->mdbox conversion. One of those tools is recovering mail from backups (easy as pie with maildir). We've got all of our email on Netapp file servers. They have nice snapshotting but the snapshots are, of course, readonly. My question: is there a doveadm command that will allow for email to be retrieved from a readonly mdbox, either directly (like manipulating the mdbox files directly) or by doveadm talking to the dovecot processes? Ideally, there'd be something like doveadm dump, but that could dump selected message contents. I've tried using IMAP with mail_location pointed at the snapshot, but, though I can get a listing of emails in the mailbox, the fetch fails when dovecot can't write-lock dovecot.index.log. If anyone has gotten something similar to work, I'd love to hear about it. A working IMAP setup would be the ideal, since it's more easily automatible (but I'll take whatever I can get). Any and all hints are most welcome!

quota clone + mysql + duplicate key
by Dimos Alevizos 05 Jun '17

05 Jun '17

I'm trying to setup quota clone with mysql on dovecot 2.2.29.1. I see in the wiki that the table is always updated to the new value (https://wiki.dovecot.org/Plugins/QuotaClone) : > Every time quota is updated, the value is updated to the cloned dict. > There are race conditions with it so the quota may not always be 100% > correct. The old value is always replaced with the new one though (not > just incremented/decremented) so the cloned quota is never too much wrong. But the queries I see don't agree : 1186029 Query BEGIN 1186029 Query INSERT INTO quota (bytes,messages,username) VALUES (25002030,226,'user(a)domain.tld') ON DUPLICATE KEY UPDATE bytes=bytes+25002030,messages=messages+226 1186029 Query COMMIT Is it a bug or am I missing something in my configuration ? The relevant part of the config : dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } plugin { quota = count:User quota quota_clone_dict = proxy::sqlquota quota_exceeded_message = Quota for this mail account has been exceeded, please try again later. quota_grace = 1M quota_vsizes = yes } map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Dimos

ACL File
by Bobber 02 Jun '17

02 Jun '17

I'm getting inconsistent behavior from my acl file. I have an acl vfile configured with this: > Jobs$* anyone lrwikst > $* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > $* user=michael.user(a)edm-inc.com lrwstipekxa > Jobs$* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > Jobs$* user=michael.user(a)edm-inc.com lrwstipekxa The Jobs folder is a public shared folder. I want just the two users to be able to have complete control of anything in the shared Jobs folder. Currently, user bob is able to move folders to sub folders but user michael is sometimes able to move folders but mostly not. I am using Thunderbird as the mail client. Sometimes I can restart Thunderbird and it will allow one operation but subsequent operations error out with Thunderbird saying the user does not have permissions. Here's my doveconf -n: > # 2.2.30.1 (eebd877): /usr/local/etc/dovecot/dovecot.conf > # OS: Linux 3.16.0-0.bpo.4-amd64 x86_64 Debian 7.11 > auth_cache_size = 8 k > auth_debug = yes > first_valid_gid = 89 > first_valid_uid = 89 > last_valid_gid = 89 > last_valid_uid = 89 > listen = * > log_path = /dev/stderr > login_greeting = IMAP service for edm-inc.com clients. > mail_location = maildir:~/Maildir > mail_plugins = " listescape acl" > namespace { > inbox = yes > location = > prefix = > separator = $ > type = private > } > namespace { > location = maildir:/home/vpopmail/domains/edm-inc.com/public > prefix = Jobs$ > separator = $ > subscriptions = no > type = public > } > passdb { > args = cache_key=%u%s > driver = vpopmail > } > plugin { > acl = vfile:/usr/local/etc/dovecot/acls:cache_secs=300 > } > protocols = imap > service auth { > user = root > vsz_limit = 64 M > } > service imap-login { > process_limit = 150 > service_count = 1 > } > ssl_cert = </etc/ssl/certs/mail_edm-inc_com.pem > ssl_key = # hidden, use -P to show it > userdb { > driver = vpopmail > } > userdb { > driver = vpopmail > } > protocol imap { > mail_plugins = " listescape acl imap_acl" > } -- *Bob Wooldridge* Blog: http://kc0dxf.net/blog/

updated to dove 2.30.1 and still the same error ....
by dovecot＠jeffandjessi.com 02 Jun '17

02 Jun '17

Well.. updated to 2.30.1 hoping it would fix this mysterious seg fault ... ,but nope ... auth: Fatal: master: service(auth): child 14502 killed with signal 11 (core dumped) the core dump shows gdb) bt #0 0x00007f7ff4a06bee in ?? () #1 0x00007f7ff74a4f44 in io_loop_handle_remove () from /usr/local/lib/dovecot/libdovecot.so.0 #2 0x00007f7ff74a3765 in io_remove_full () from /usr/local/lib/dovecot/libdovecot.so.0 #3 0x00007f7ff7438b62 in master_service_deinit () from /usr/local/lib/dovecot/libdovecot.so.0 #4 0x00000000004307ef in main () no symbols are available as this is a pkg install.... so whats next? time to dump dovecot after running it for 10 years? Can't believe no one else is seeing this .... the symtoms are dovecot starts up fine when a client connects, they authorize just fine and download email .... about a minute later the auth process crashes and the entire process starts over .... so how do you trouble shoot this ... it sounds like a coding issue some place .... anyone ?

Re: Retrieving mail from read-only mdbox

> I've tried using IMAP with mail_location pointed at the snapshot, but, > though I can get a listing of emails in the mailbox, the fetch fails when > dovecot can't write-lock dovecot.index.log. I've thought about doing this someday (adding snapshots to a user's namespace) but never got around to doing it. Snapshots get rotated (e.g. hourly.1 -> hourly.2 -> etc.) so every hour, so any indices produced gets invalidated. You would need to generate MEMORY indices to create it on the fly. Something like namespace snapshots { location = ...:INDEX==MEMORY ... } I'm not sure how dovecot would react when NetApp pulls the rug out from under one of the hourly snapshots and replace it with the next hour's version.

Two domains, same users
by Sandbox 01 Jun '17

01 Jun '17

Hi, I have two LDAP domains, which has some equal users, eg: abc(a)domain1.com abc(a)domain2.com I sat up this config: domain1 users maildirs are stored in /home/vmail/username domain2 users maildirs are stored in /home/vmail/domain2/username This works fine except one thing: i cant set up the ldap query to choose the correct maildir if the user names are equal. Is it possible to use a user_filter which will choose the correct maildir and user/domain from the email address? My current ldap.conf for domain1: hosts = ldap.domain1.com base = ou=People,dc=domain1,dc=com ldap_version = 3 user_attrs = uid=user user_filter = (uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 and for domain2: hosts = ldap.domain2.com base = ou=People,dc=domain2,dc=com ldap_version = 3 user_attrs = \ =mail=maildir:/home/vmail/%{ldap:departmentNumber)/%n/Maildir user_filter = (uid=%n) pass_attrs = uid=%n,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 Thanks, Robert

sieve folders in maildir with imap: not a directory not fixed with maildir_stat_dirs = yes
by David Gessel 01 Jun '17

01 Jun '17

As my logs fill up with "imap(user(a)domain.com): Error: stat(/mail/doman.com/user//.dovecot.sieve/tmp) failed: Not a directory" errors, I followed the advice at https://wiki2.dovecot.org/VirtualUsers/Home and https://dovecot.org/list/dovecot/2016-June/104403.html and set in /usr/local/etc/dovecot/conf.d/10-mail.conf # By default LIST command returns all entries in maildir beginning with a dot. # Enabling this option makes Dovecot return only entries which are directories. # This is done by stat()ing each entry, so it causes more disk I/O. # (For systems setting struct dirent->d_type, this check is free and it's # done always regardless of this setting) maildir_stat_dirs = yes My mailbox format reads "mail_location = maildir:~:CONTROL=/var/no-quota/%u:INDEX=MEMORY" The error is factually correct, but there is not .dovecot.sieve/tmp directory or file as .dovecot.sieve is a file (the head sieve script that calls the subordinate scripts out of the /sieve directory. There is a tmp directory at /sieve/tmp/ drwxr----- 2 vmail vmail 2B May 31 04:14 tmp Any hints as to why this isn't working? It does seem like the right answer.

shared folder and private index file problems
by Thomas Robers 31 May '17

31 May '17

Hello, I'm using Dovecot 2.2.30 with Pideonhole 0.4.18 and I'm having some problems, perhaps someone can give an hint on how to solve them. When I try to create a folder in the toplevel directory of a shared mailbox, i get a "permission denied" although I have the rights, example: 1.doveadm -f table acl rights -u bob(a)example.com shared/bill(a)example.com Rights lookup read write write-seen write-deleted insert post expunge create delete admin 2.doveadm mailbox create -u bob(a)example.com "shared/bill(a)example.com" doveadm(bob(a)example.com): Error: Can't create mailbox shared/bill(a)example.com: Permission denied Creating an subfolder of a folder which already exists works fine: 1.doveadm -f table acl rights -u bob(a)example.com shared/bill(a)example.com /Drafts Rights lookup read write write-seen write-deleted insert post expunge create delete admin 2.doveadm mailbox create -u bob(a)example.com "shared/bill(a)example.com /Drafts/Test" (no output) 3.doveadm -f table acl rights -u bob(a)example.com shared/bill(a)example.com /Drafts/Test Rights lookup read write write-seen write-deleted insert post expunge create delete So this works, but creating a folder directly in the inbox of the shared mailbox doesn't work and I don't know why. Is this not supported? Or do I miss something important? Another problem I have is, that the private index files in shared folders are often to always marked as inconsistent in the dovecot log file, an example of such log messages look like: - imap(bob(a)example.com): Error: /export/home/imap/bob(a)example.com/shared /bill(a)example.com/.Templates/dovecot.index.pvt view is inconsistent - imap(bob(a)example.com): Error: /export/home/imap/bob(a)example.com/shared /bill(a)example.com/.Templates/dovecot.index.pvt view is inconsistent - imap(bob(a)example.com): Error: /export/home/imap/bob(a)example.com/shared /bill(a)example.com/.Trash/dovecot.index.pvt view is inconsistent - imap(bob(a)example.com): Error: /export/home/imap/bob(a)example.com/shared /bill(a)example.com/.Trash/dovecot.index.pvt view is inconsistent And this is logged for almost every user who has access to a shared mailbox and I don't know how to stop getting the indexes inconsistent.

Timo Sirainen announced > + If dovecot.index.cache corruption is detected, reset only the one > corrupted mail instead of the whole file. Is this a big performance win? I still have users with jumbo mailboxes who insist on direct mailbox file access using procmail or mail readers, which trigger index rebuilds when dovecot accesses them.

You misundertand how SSL (or TLS) vs STARTTLS works. SSL/TLS (on port 993) starts negotiating a secure session protocol right after connection, which involves binary exchange of data, certificates, etc.. This is what "openssl s_client ..." does, but telnet does not. Only after the SSL handshake completes will you get banners, etc. STARTTLS starts out as a unencrypted session and thus, you'll get the initial banner. The client is then expected to initiate a secure session by issuing a STARTTLS directive, whereupon client and server starts the secure session negotiation like above. To test this, you would use openssl s_client -starttls imap -connect localhost:143 So telnet doesn't work because it does not do SSL. Your MUA don't work because of the same misunderstanding, or there's some network issue at play. You need to align your clients to use the security protocol you've enabled.

Fatal error with IMAP MOVE from a shared mailbox to Trash folder
by Daniele Barresi 30 May '17

30 May '17

Hello everyone. I have a problem using Dovecot 2.2.26 with ACL plugin and deleting e-mails from a shared mailbox. My user doesn't have the "expunge" permission on the shared mailbox, but it has the "write-deleted" permission. So, when I delete a message from the shared mailbox using a client that implements the IMAP MOVE command, it tries to move the message to my Trash folder. Then the server closes the connection to the client (process aborted) and I get three lines in the log file with a backtrace and "Fatal" error. In this case the message doesn't get copied or moved from the shared folder and the client complaints. I found the same thing happens whenever I try to move anything between folders of the shared mailbox itself, while logged in with my user. I can move messages inside my own mailbox just fine. If I try the same operation from a client that uses the IMAP COPY + DELETE commands, no errors are logged and the outcome is as expected: the message gets copied from the shared folder to my Trash and gets the flag "\Deleted" set on the shared folder. My setup is as follows: Dovecot: 2.2.26.0 OS: Ubuntu 16.04.1 LTS CPU architecture: x86_64 Filesystem: ext4 The relevant lines from mail.err log: Dec 27 15:21:18 dovecot dovecot: imap(danielebarresi): Panic: file mail-storage.c: line 2143 (mailbox_save_context_reset): assertion failed: (ctx->copying_via_save) Dec 27 15:21:18 dovecot dovecot: imap(danielebarresi): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x9438e) [0x7fbcd478538e] -> /usr/lib/dovecot/libdovecot.so.0(+0x9447c) [0x7fbcd478547c] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fbcd471ea4e] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x41b78) [0x7fbcd4a50b78] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_save_cancel+0x73) [0x7fbcd4a53d73] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so(+0xe142) [0x7fbcd3f1d142] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x4516d) [0x7fbcd4a5416d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_move+0x23) [0x7fbcd4a54333] -> dovecot/imap(+0xf9c5) [0x557cf98629c5] -> dovecot/imap(command_exec+0xa6) [0x557cf986f196] -> dovecot/imap(+0x1a4c2) [0x557cf986d4c2] -> dovecot/imap(+0x1a550) [0x557cf986d550] -> dovecot/imap(client_handle_input+0x195) [0x557cf986d915] -> dovecot/imap(client_input+0x85) [0x557cf986de25] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7fbcd4799bdc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10a) [0x7fbcd479b09a] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7fbcd4799c65] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fbcd4799e08] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fbcd4724f53] -> dovecot/imap(main+0x322) [0x557cf9860ca2] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7fbcd4348830] -> dovecot/imap(+0xde1f) [0x557cf9860e1f] Dec 27 15:21:18 dovecot dovecot: imap(danielebarresi): Fatal: master: service(imap): child 6907 killed with signal 6 (core dumped) Dovecot configuration (doveadm -n): #

I tested and reproduced the error with Thunderbird and Roundcube. The Apple Mail client uses IMAP COPY + DELETE, instead of IMAP MOVE, and no errors are reported. So I think it's related to the IMAP MOVE implementation on Dovecot server. Has anyone seen the same error? Any suggestions? Is this a Dovecot bug? --- Daniele Barresi

Question about how to serve many imap users on some mailbox.

Hi, dear dovecot users! I am running 2.2.29.1 (e0b76e3) on FreeBSD. In my case, one mailbox info(a)example.com is shared between 5-10 managers. Sometimes they complains that no new messages displayed in folder message count list in brackets (bold number if new messages exists), but when they click on the imap folder (for example Inbox) they could see many new mails.

Can only enable Sieve scripts not edit them (Roundcube)
by Paul Littlefield 29 May '17

29 May '17

Hello, (my first post so be gentle) I will be posting this to the Roundcube mailing list too, but thought it worth asking here as well. I have a Roundcube installation running Apache with Dovecot and Sieve. When logged in to Roundcube, a user can see the Sieve scripts and enable or disable them but NOT edit them or create new scripts. In other words, Dovecot will happily EDIT the script to mark it as 'false' but will not edit the actual rules or create a new rule... e.g. require ["fileinto","vacation"]; # rule:[Out of Office] if false # true { vacation :days 1 :addresses "me(a)mydomain.com" :subject "Out of Office" :from "me(a)mydomain.com" "I am out of the office."; } # rule:[Spam] if header :contains "subject" "{Spam}" { fileinto "Spam"; } Any ideas? Thanks, -- Paul Littlefield

When will passdb callback to mechanism yield PASSDB_RESULT_NEXT?
by Peter Mogensen 29 May '17

29 May '17

Hi, code question... I've been trying to figure out the implications of the new "noauthenticate" passdb field. Internally it causes a passdb to result in PASSDB_RESULT_NEXT. When a SASL mechanism calls auth_request_lookup_credentials(...,callback) the passdb result is passed to the callback. But I can't really figure out when that result will ever be PASSDB_RESULT_NEXT. It seems the passdb fallthrough resolver will always replace it with PASSDB_RESULT_INTERNAL_FAILURE if it ends up being the last result. Can it ever leak into the callback or is it an internal intermediate value or the passdb resolver? /Peter

Another mail_crypt question: figure out to password secure using mysql
by dovecot＠avv.solutions 26 May '17

26 May '17

Hello Community, (sorry to be more busy, hence more running questions in parallel :) ) As mentioned in another post, I am testing mail_crypt plugin. I was wondering how to really secure the process sothat even the admin cannot have any access to the other users mail content. My current config is simple: - using per-folder keys (hence the per-user spaces are preserved) - put the public/private global keys in base64 format into the sql DB (elliptic algo) This obviously allows anyone with read access to the table to decrypt the mails from the filesystem... which I try to prevent. Considering of course that all mail users are virtual and do not (and may not) have access to the box itself: - how can I secure the keys? I do not see how to handle a assword for them? - a solution might be to crypt/decrypt the keys using the user's password? - other? Thank you for you help.

Still 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 .... anybody have any ideas how to trouble shoot this or is this a bug in the software .... help !!
