Unable to see virtual users
by Randall Gellens 01 Dec '14

01 Dec '14

I have a new Dovecot v2.2.9 installation and am having trouble getting virtual users recognized. Also, the example configuration listed on the Wiki generates config errors. Note that I haven't tried running dovecot yet, I wanted to verify that the config looked good first. First, my configuration. I'm trying to use /etc/dovecot/users as my combined userdb and passdb file, with all users having a UID/GID of vmail, and a home directory of /local/mnt/home/<user> ---------- $ sudo doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-39-generic x86_64 Ubuntu 14.04.1 LTS ext4 auth_verbose = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mdbox:/local/mnt/mail/%n 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 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 { args = username_format=%n /etc/dovecot/users driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = randy(a)qti.qualcomm.com protocols = " imap sieve pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail home=/local/mnt/home/%n driver = passwd-file } userdb { driver = passwd } ---------- Next, my /etc/dovecot/users file: $ cat /etc/dovecot/users fred:x test:{SSHA}amehbJZYxKWuIbywINVNWxKcPrWi27a+ poptest2:x poptest3:x ---------- If I ask dovecot what it knows about user 'test' it says the user doesn't exist: $ sudo doveadm user test field valueuserdb lookup: user test doesn't exist ---------- If I ask about a user in /etc/passwd, it finds it: $ sudo doveadm user nobody field value uid 65534 gid 65534 home /nonexistent mail mdbox:/local/mnt/mail/nobody system_groups_user nobody ---------- As an aside, when I copied the sample config entries from http://wiki2.dovecot.org/UserDatabase it got config errors: userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail override_fields = skip = never result_failure = continue result_internalfail = continue result_success = return-ok } The 'skip', 'result_failure', etc. entries all generated config errors as being unknown.

Working with Active Directory on Windows Server 2012 R2
by Aaron Jenkins 30 Nov '14

Hi all, I’m having issues getting Dovecot to work with AD on 2012 R2 in a test environment. Background: AD is running on dc1.ad.automaton.uk<http://dc1.ad.automaton.uk>, the domain is ad.automaton.uk<http://ad.automaton.uk>. The DNS server is running on ad.automaton.uk<http://ad.automaton.uk> and the automaton.uk<http://automaton.uk> DNS is set up correctly in the test environment in that everything resolves to the correct IP address and I can authenticate with whichever LDAP clients (ldapsearch, ApacheDS, sssd). It refuses to bind on Dovecot for some reason. aaron@mail:/var/log$ uname -a Linux mail.ad.automaton.uk 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux aaron@mail:/var/log$ dovecot --version 2.2.9 aaron@mail:/var/log$ dpkg -l | grep dovecot ii dovecot-core 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - core files ii dovecot-gssapi 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - GSSAPI support ii dovecot-imapd 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-ldap 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - LDAP support aaron@mail:/var/log/$ cat dovecot-debug.log … Nov 19 09:22:23 auth: Debug: auth client connected (pid=10345) Nov 19 09:22:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:23 auth: Debug: client passdb out: CONT 1 Nov 19 09:22:23 auth: Debug: client in: CONT 1 (previous base64 data may contain sensitive data) Nov 19 09:22:29 auth: Debug: client passdb out: FAIL 1 user=aaron.jenkins temp Nov 19 09:22:29 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:39 auth: Debug: client passdb out: FAIL 2 user=aaron.jenkins temp Nov 19 09:22:40 auth: Debug: client in: AUTH 3 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:44 auth: Debug: client passdb out: CONT 3 Nov 19 09:22:44 auth: Debug: client in: CONT 3 (previous base64 data may contain sensitive data) Nov 19 09:22:50 auth: Debug: client passdb out: FAIL 3 user=aaron.jenkins temp Nov 19 09:22:50 auth: Debug: client in: AUTH 4 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:56 auth: Debug: client passdb out: FAIL 4 user=aaron.jenkins temp (I’ve removed the base64 as it might contain passwords I actually use, if it’s important I’ll re-run it with a different password unredacted) Do you guys have any ideas on how to get it working with 2012 R2?

how to start a replication master-master correctly
by Eduardo Casarero 28 Nov '14

28 Nov '14

Hi all, I currently have one dovecot 2.2.15 working and I would like to add a second master server. If I configure the second server and enable the dsync in both servers, the sync will copy everything from A to B ? I mean, B server won't remove messages in A as it doesn't have anything in its users mailbox? The second master server will be a cold server just for contingency. Thanks

Move mail behavior
by Martin Stigge 27 Nov '14

27 Nov '14

Hi! I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the old behavior. I observe this with Evolution as well as Icedove (Thunderbird) mail clients, which is why I assume that it's actually a change in the IMAP server behavior. Is it supposed to behave like that? Is there a way to configure this? Regards, Martin

2.2.15: SMTP submission server?
by Ron Leach 27 Nov '14

27 Nov '14

List, we're migrating to 2.2 from a 1.x version. There has been mention from time to time of a dovecot SMTP submission server. Last I saw was Timo suggesting this would be a 2.3 feature, but that there was already a 'basic' capability in 2.2 that, more or less, merely provided a secured/authorised SMTP submission. I haven't found anything about this in the wiki, but the feature is of interest to us. I would like to *not* have our MTA capable of being exploited as a relay (it isn't, at the moment) whereas users are logging into our dovecot from offsite using imaps with passwords. While moving to 2.2, I'd like to try to use a secure SMTP submission *separate* from the MTA so that that software, with whatever vulnerabilities or weaknesses it might have, remained locked down and could not relay, if at all possible. (Imaps with passwords means the login details are not transmitted in cleartext and, so, leak no security to an observer of the communications channel. Doubtless there are other weaknesses somewhere but, at least, when using hotel wifi, for example, there is little chance of revealing login details to a packet sniffer. It won't be perfect, there are probably other vulnerabilities, not least in the underlying OSs at each end, but the connection - which is a serious vulnerability in many places - will be as good as is practical to make it.) So, is there some kind of SMTP submission service for a logged in dovecot user, and how would a client make use of that? Is it possible to setup 2.2.15 for this? And, crucially, would the connections between the client (eg at a hotel in some unreliable location) be encrypted right from the start, not using STARTTLS, as is the case in imaps? And, just to be really demanding, could we configure its use on a non-standard port? regards, Ron

2.2.15 Panic in mbox_sync_read_next_mail()
by Hans Morten Kind 27 Nov '14

27 Nov '14

It might not be a fault in dovecot, as the user is accessing the folder locally with alpine while also running imap-sessions. However it would have been nice with a more graceful action than panic? The panic is preceeded by Error: Next message unexpectedly corrupted in mbox file PATH Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) At #7 in the enclosed backtrace the actual values are sync_ctx->input->v_offset = 564 mail_ctx->mail.from_offset = 564 sync_ctx->input->eof = 0 Some will recommend convertion to maildir, but with 25 years history, thousands of active users and dozens terrabytes of mboxes, we are not even considering it. hmk GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Pigeonhole, vacation being sent incorrectly
by Harry Mills 26 Nov '14

26 Nov '14

Hi, I have an issue with a vacation message in a sieve script. I can't see an error in the script itself. Pigeonhole version: 0.4.2-32 Dovecot Version: 2.2.10 The script was created by Ingo (part of the Horde suite), but I think the script is fine. The problem is that when a message is sent to the "everyone" group (and alias for every person in the organisation), vacation messages are being sent back which I believe is an error. The script is: =============================================== # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (11/11/14, 5:20:06 pm GMT) require ["vacation", "regex", "fileinto"]; # Vacation if allof ( not exists "list-help", not exists "list-unsubscribe", not exists "list-subscribe", not exists "list-owner", not exists "list-post", not exists "list-archive", not exists "list-id", not exists "Mailing-List", not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2014) (\$.*\$ )?..:..:..

I cannot see the address for "user2(a)example.com" in any of those fields, or indeed referenced anywhere in the email. Is this a bug, or am I misunderstanding something?

imap-login segfaults when using post-login
by Nico Rittner 26 Nov '14

26 Nov '14

hello, i get these lines in syslog when using post-login within imap-login: imap-login: Fatal: master: service(imap-login): child 574 killed with signal 11 (core dumps disabled) imap[5523]: segfault at 14 ip b7556276 sp bfc1c940 error 4 in libdovecot.so.0.0.0[b7529000+d4000] these are the relevant sections i added: service imap-login { executable = imap post-login } service post-login { executable = script-login /path/to/exec } i also used /bin/true as /path/to/exec to exclude the used exec itself as the reason. same result. version is 2.2.13 on gentoo-linux. i wonder if this error is gentoo-specific (cflags/etc...) or a bug in dovecot. this behaviour can be reproduced on two other of my gentoo-machines. same configuration worked in previous versions, don't know the exact version number. thanks a lot for your suggestions. i'll also cc to the gentoo-people. nico

slow incremental indexing of maildirs with squat
by vitalif＠yourcmc.ru 26 Nov '14

26 Nov '14

Hi! I'm using Dovecot 2.1.7 on Debian Wheezy 32-bit (package version is 1:2.1.7-7+deb7u1) with maildirs. My problem is that the incremental indexing of maildirs with squat takes a very long time... I don't know if it reindexes anything, but it seems it iterates though all messages on each search query and reads them. It works fast only on successive queries within several minutes, probably because of the messages being in cache. What do you think, is it a bug? -- With best regards, Vitaliy Filippov

Shared mailboxes using SQL
by Daniel Miller 26 Nov '14

26 Nov '14

I recently tried to change from the simple file to a SQL dictionary for ACL. While the Wiki instructions seemed fairly clear I was having errors. After some further digging, and a little thinking - I read the errors and tried to infer what was happening. I have some IMAP groups configured for sharing. And I guessed the example dictionary didn't allow for them. Looking at my existing shared-mailboxes.db flat file I saw something that gave me a clue. So I added the following: map { pattern = shared/shared-boxes/group/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } And things started working again! A suggestion that perhaps this be added to the wiki - possibly with a bit more information on the "map" sections. Also - would there be any benefit to setting up a separate SQL table for groups? -- Daniel

v2.2.14 released
by Timo Sirainen 26 Nov '14

26 Nov '14

http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz.sig Looks like it took a bit longer to make this release after RC1 than I thought. I'm now in San Jose area for a few months and still jumping between apartments and trying to adjust to the new timezone. Some of the more important fixes since RC1: - Fixed several race conditions with dovecot.index.cache handling that may have caused unnecessary "cache is corrupted" errors. - auth: If auth client listed userdb and disconnected before finishing, the auth worker process got stuck (and eventually all workers could get used up and requests would start failing). Some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

Possible to adjust username used to determine the proxy destination?
by Andy Dills 25 Nov '14

25 Nov '14

I'm in a fairly standard cluster environment: shared storage, bunch of servers each acting as both proxies and backends. We do /bin/checkpassword authentication, allowing a great deal of flexibility...protection against brute force, billing mechanisms, but relevant to this issue, I have it set up to allow users to login with either their username (if they are in one of our default domains) or their email address. I'm realizing now that as a consequence of this, "joe" and "joe(a)xecu.net" are unique as far as dovecot is concerned. Users who login with just their username (and not the full email address) can get assigned to a different backend server than when they login with the full email address (which would also include LMTP deliveries). This has been happening for years, a few broken indexes here and there that seem to resolve themselves, so it hasn't been impacting the service, but I'd like to correct it properly. Is there a way to manipulate this? For example, if I moved the authentication to the proxy layer (it's currently proxy=y nopassword=y), and set $ENV{USER} to the full email address, will director use that for selection instead of the user-supplied username? I'm open to suggestions on how best to accomplish this. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

doveadm backup for all users to file system
by Jeff Larsen 24 Nov '14

24 Nov '14

The wiki says that doveadm backup supports the -A option for all users, but when I specify a file-system destination (like /tmp, or an NFS mounted folder), it just rewrites each user backup to the same location overwriting the previous user's content. You end up with just the content for the last user processed. I tried the typical %u substitution but that just created folder named '%u' and had the same overwrite problem. My userdb is LDAP which works just fine for other doveadm commands. The verbose/debug output from doveadm backup shows that it is processing every user. Example: doveadm -vD backup -A sdbox:/tmp/backup My understanding is that "doveadm backup" is just a front-end for dsync. The dsync manpage on the other hand says "dsync can currently sync only one user at a time. If you want to dsync all users, you'll need to get a list of all users and execute dsync separately..." It appears that "doveadm backup -A" is doing the iteration for me, but it's not generating individual destination paths for each user. So, is this is a documentation problem for "doveadm backup"? Or am I missing something here? Is there some secret sauce for "doveadm backup -A" that I'm not finding? If all else fails, I know I can write a script to iterate over the available users and run the backup repeatedly, but I would like to keep this as simple as possible. Thanks, Jeff

Hi list, I get these warnings quite frequently. Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync Is this something to worry about? Otherwise the replication works perfectly.

Outlook 2010 not connecting to secure POP3
by Robert Moskowitz 24 Nov '14

OK, I did not know that this user has a new computer with Outlook 2010. This SHOULD make it easier but... I have the computer right next to me, they brought it over. It is on the same LAN as this notebook. I can access my server with: openssl s_client -connect z9m9z.htt-consult.com:995 And then log the user in with the appropriate POP3 credentials. In Outlook 2010, in Advanced settings I have specified "This server requires an encrypted connection (SSL)" and it switches to port 995 (from 110). I try connecting and I get an error that "Your server does notg support the connection encryption type you have specified." The first time we tried this it installed my self-signed cert in the local cert store. Any idea on what is going on or how to get this working?

Strange repplication issues
by Bertrand Caplet 24 Nov '14

Hi, I know there are lots of questions about replication, but I searched and didn't find my question. I've got some problems with syncing. I've got 2 servers: A and B When a email arrives on server A sometimes it's not syncing in server B I think server A doesn't always notify server B there are new mails to sync. But I don't know how to fix it. And I spotted something, when it isn't syncing. The only thing to do is to send local or remote mail to server B and then it sync or do a "doveadm sync -A tcp:serverB.example:port" of course. My doveconf -n of the two servers are in attachements bellow. By the way both of my dovecot servers are v2.2.9 P.S.: I didn't test from server B to A but I think it's the same problem.
