Deafness
by Steffan Cline 29 Jul '15

29 Jul '15

I’ve started in the last day or so having issues where users get a timeout when connecting to dovecot. The iPhone interprets this as an auth issue but re-entering the password makes no change. Outlook will either just not connect to it at all or it gives an error to re-enter the password also with no change. This happens within an hour of a "service dovecot restart". I’m using CentOS 6 with dovecot 2.0.9 from the centos repos. There’s nothing visible in the logs. Suggestions of what to check for? Thanks, Steffan

dbox: message internal date
by Francesco 29 Jul '15

29 Jul '15

Hello everyone and thanks in advance for the help :) I'm trying to figure out where does dovecot store the message internal date when using single dbox storage format. In Maildir format, the internal date is determined by the actual date of the file on the filesystem, but in dbox it doesn't seem to be the case. I'm looking forward for a way to modify a message internal date when on a dovecot instance running dbox storage engine, maybe anyone knows if it's possible and how to accomplish this? Again, thank you for the help Sincerely Francesco

sharing INBOX with ACL -> share all folders
by Marco Giunta 28 Jul '15

Hi at all, I have a problem with ACL; I want to share INBOX and Sent folder to an other user, but when I configure ACL on INBOX, all folders are shared (Sent, Junk, Draft, Trash, etc) # doveadm acl get -u janedoe INBOX ID Global Rights user=johndoe expunge insert lookup post read write write-deleted write-seen # doveadm acl get -u janedoe Sent ID Global Rights user=johndoe expunge insert lookup post read write write-deleted write-seen # doveadm acl get -u janedoe Trash ID Global Rights # doveadm acl get -u janedoe Drafts ID Global Rights # doveadm acl get -u janedoe Junk ID Global Rights # doveadm mailbox list -u johndoe Trash Junk Drafts Sent Archives Archives.2015 Other Users Other Users.janedoe Other Users.janedoe.Junk Other Users.janedoe.Drafts Other Users.janedoe.Sent Other Users.janedoe.Trash Other Users.janedoe.INBOX INBOX If I remove the INBOX ACL, only 'Sent' folder is shared, as expected: # doveadm acl delete -u janedoe INBOX johndoe # doveadm mailbox list -u provahe Trash Trash.saved-messages Junk Drafts Sent INBOX_spam Archives Archives.2015 Archives.2015.INBOX_spam Other Users Other Users.janedoe Other Users.janedoe.Sent INBOX My Dovecot instance use a single user, and all my mailboxes use standard maildir files: drwx------ 9 vmail mail 0 Jul 28 10:59 . drwx------ 12 vmail mail 3864 Jul 28 09:39 .. drwx------ 2 vmail mail 0 Jul 28 09:51 cur -rw------- 1 vmail mail 0 Jul 28 10:59 dovecot-acl -rw------- 1 vmail mail 16 Jul 28 10:59 dovecot-acl-list -rw------- 1 vmail mail 1448 Jul 28 09:51 dovecot.index.cache -rw------- 1 vmail mail 1016 Jul 28 09:52 dovecot.index.log -rw------- 1 vmail mail 113 Jul 28 09:51 dovecot-uidlist -rw------- 1 vmail mail 8 Jul 28 09:39 dovecot-uidvalidity -r--r--r-- 1 vmail mail 0 Jul 28 09:39 dovecot-uidvalidity.55b731ac drwx------ 5 vmail mail 0 Jul 28 09:39 .Drafts lrwxrwxrwx 1 vmail mail 5 Jul 28 09:39 .INBOX_spam -> .Junk drwx------ 5 vmail mail 0 Jul 28 09:39 .Junk -rw------- 1 vmail mail 16 Jul 28 09:39 maildirsize drwx------ 2 vmail mail 0 Jul 28 09:51 new drwx------ 5 vmail mail 0 Jul 28 09:50 .Sent -rw------- 1 vmail mail 37 Jul 28 09:39 subscriptions drwx------ 2 vmail mail 0 Jul 28 09:51 tmp drwx------ 5 vmail mail 0 Jul 28 09:39 .Trash any clue to solve my problem ??

Importing mbox archives into a inbox?
by Paul Hoffman 27 Jul '15

27 Jul '15

Greetings from a dovecot newbie. I have a bunch of mailing list archives (in mbox) format that I want to dump into the inbox for a particular account on the system. I want them to retain all of their information, particularly the date. I'm not seeing how to do this, but I could be missing it. Is this LDA or LMTP with some command-line options I'm not seeing? --Paul Hoffman

POP3 getting previously delivered messages.
by Jas Reehal 24 Jul '15

24 Jul '15

Hi All, This is my first post to this list. I have recently upgraded to dovecot version 2.2.10. 1. I have one POP3 user who does not want to delete his email on the server. 2. He has accumulated over 19000 messages, and the 'dovecot.uidlist' file has more than 19000 lines! 3. Occasionally now when he has received one or more new emails, and his email client does a 'get new mail' operation (POP3) he begins to receive email he has already received previously. last time this happened all 19000+ messages were delivered again, leaning to duplicate entries in all his mailboxes. I have reproduced this issue with a dummy email account with a POP3 client, leaving all messages on the server. I have delivered 20000 messages to this email account, each about 1.3k ins size and each with .... Subject: Message number <n> Body containing "Message number <n>" where <n> is 1 to 20000 now occasionally if I send another message to this email account, and then check for new messages using a POP3 client I get more messages downloaded than I expect! The 'dovecot.uidlist' file is not corrupt, but I beleive due ti it's size (number of lines) the is an issue on compiling a ' POP3 drop-list'. I have attached a file 'dovecot-a.txt' which shows the 'dovecot -a' output from my server. Based on what I have investigated I believe that this issue may not be correlated with a migration to version 2.2.10, but more to do with the number of messages retained on the server. Is there anyone who has any insight into what is happening and if there is any remedy, perhaps a "pop3_client_workarounds =" or other POP3 or UIDL directive in the conf files? The user is stubbornly resisting migration to IMAP, because of the time and effort he says will be required to replicate his organised filing/storage of messages on the server.

possible patch for ACL SQL ERROR: duplicate key value violates unique constraint "user_shares_pkey"
by Steffen Kaiser 24 Jul '15

24 Jul '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm using Postgres as dict backend now and then I get this error, when someone changed ACLs, actually for some reason some users, who get permission from other users, get this error quite often: dict: Error: sql dict: commit failed: ERROR: duplicate key value violates unique constraint "user_shares_pkey" (query: INSERT INTO user_shares (dummy,to_user,from_user) VALUES ('1','user1','user2')) It looks like that this error is triggered, when a MUA is connecting to Dovecot after ACLs had been changed and opens several mailboxes at once. So two or parallel Dovecot instances try to insert the record simultaneously. With a similiar technique to the quota problem, I added a trigger. The idea is to use the condition dummy ISNULL to detect, that the function was triggered from the INSERT of the function itself, hence, breaking the recursive triggers. This assumes that dummy is never NULL from Dovecot. The same applies to anyone_shares, just remove the to_user field from the function. Does somebody see something wrong with my hack? ============= CREATE FUNCTION insert_sharing() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN IF NEW.dummy IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert return NEW; END IF; LOOP UPDATE user_shares SET dummy = NEW.dummy WHERE from_user = NEW.from_user AND to_user = NEW.to_user; IF found THEN -- updated and inserted RETURN NULL; END IF; BEGIN INSERT INTO user_shares (from_user,to_user,dummy) VALUES (NEW.from_user,NEW.to_user,NULL); --- return NULL; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; -- Update dummy after INSERT END LOOP; END; $$; CREATE TRIGGER insertsharing BEFORE INSERT ON user_shares FOR EACH ROW EXECUTE PROCEDURE insert_sharing(); - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBVbHxJXz1H7kL/d9rAQIn5gf/dNMQKmmigGrbccGQQrsGU66B6OHvTY7L 1vyh8hgr985KNk2/Ws/usLnAqpl5jhpo8kVPLI8TqcGYLAS/67TOIFrwLKAEBU96 e+QpbqqiSm66mZwWOQZgCI63+Fh7fdBUMREL6UqGleFF1GrzNnjmX4MGecbpu/L9 gQMAGUG++/S+ka9S6B275RXIj9DvWzq/oYqJ1M1grGckUxXfDk5szLyvuIJ981At 20qaCHEIlIOlkQ0ttE4W+RWkkYS2rMJvCzQelF4pcm6vaxhXxvqUryzmy9pv+UUT osqS6igWt7BPXF7ku8+rKYVp/qPZrh9IWXMsajr/2nI+V5gRb6u2ow== =gb1P -----END PGP SIGNATURE-----

Authenticate system user with alternate password
by AC 23 Jul '15

23 Jul '15

Is there a way to configure Dovecot to authenticate a system user against a different password list? I want to give my own personal account on my machine a password for IMAP and have that be different from the password I use to log into the system for maintenance purposes. I currently do this for outbound email by having the MTA authenticate against a SASL database during the initial SMTP connection (STARTTLS).

dovecot proxy/director and high availability design
by Chad M Stewart 21 Jul '15

21 Jul '15

I'm trying to determine which dovecot components to use and how to order them in the network path from client to mail store. If I have say 1,000 users, all stored in MySQL (or LDAP) and have 4 mail stores, configured into 2, 2 node pods. MS1 and MS2 are pod1 and are configured with replication (dsync) and host users 0-500. MS3 and MS4 are pod2 and are configured with replication between them and host users 501-1000. Ideally the active connections in pod1 would be split 50/50 between MS1 and MS2. When maintenance is performed obviously all active connections/users would be moved to the other node in the pod and then rebalanced once maintenance is completed. I'm not sure if I need to use both the proxy and director, or just one or the other? If both then what is the proper path, from a network perspective? I like the functionality director provides, being able to add/remove servers on the fly and adjust connections, etc.. But from what I've read director needs to know about all mail servers. The problem is that not all servers host all users. User100 could be serviced by ms1 or ms2, but not by ms3 or ms4. I'm trying to design a system that should provide as close to 99.999% service availability as possible. Thank you, Chad

Dovecot in UCS
by Daniel Tröder 21 Jul '15

21 Jul '15

Hello :) I hope you can forgive me a little advertisement: The English translation of my blog post on the Dovecot integration I did for the Univention Corporate Server (UCS) is online: https://www.univention.com/2015/07/dovecot-is-the-default-imappop3-mail-ser… UCS is a Debian based Linux Distribution, everything - incl. management bits - is OSS. There is a "Core Edition" that you can download and use (also commercially) for free, that is - despite its name - feature complete: https://www.univention.com/downloads/ucs-download A lot of interesting Dovecot features can be changed without breaking things, so this blog post may be interesting to everyone. The German version can be found here: https://www.univention.de/2015/07/mailserver-dovecot-als-standard-imappop3-… Greetings Daniel Tröder

[Dovecot Antispam] Can't seem to load plugin
by James Lott 21 Jul '15

21 Jul '15

Hello list, I'm hoping there is a user of the antispam plugin out there who might be able to lend a pointer or two. I am running dovecot 2.2.18 on FreeBSD 10 (doveconf -n attached), where I have installed the binary dovecot2-antispam-plugin package. I have put together what should, in my estimation, be a working configuration for the plugin. I have reviewed the man page and the online documentation, and I think at the *very least* I should be seeing errors for something not working correctly. However, what I have is a great deal more troubling. There is no sign on the plugin even attempting to load. No log entries, no errors, nothing. The plugin is definitely in the right place with the right name, since I let the package manager handle all of that for me root@zerolag:~ # ls -l /usr/local/lib/dovecot/lib90_antispam_plugin.so -rwxr-xr-x 1 root wheel 32488 Jul 2 09:41 /usr/local/lib/dovecot/lib90_antispam_plugin.so I am unable to make any sense of this. Thanks in advance for any pointers :) -- James Lott

Problems with IMAP/POP and dovecot director on backend (director_proxy_maybe)
by dominik 20 Jul '15

20 Jul '15

Hello dovecot community, first of all: dovecot ist great! ;) ...nevertheless I´ve got some problems to get my director scenario running as needed/expected :( My scenario: I´d like to configure two dovecot backends, without the need for multiple dovecot instances. Both backend servers are active/active and act on top of a glusterfs storage, which implies the need for dovecot director. As described in release notes (v2.2.17) this should be possible by setting the extra field "director_proxy_maybe=yes".: "+ director: Implemented director_proxy_maybe passdb extra field to be able to run director and backend in the same Dovecot instance. (LMTP doesn't support mixed proxy/non-proxy destinations currently.)" My setup: * 1 LMTP client (SLES11p3 with postfix) * 1 IMAP/POP3 client (Debian8 with thunderbird 31.6.0): 10.0.0.26. The client connects through a dovecot mailproxy or direct. * 1 dovecot mailproxy: 10.0.1.151 * 2 mailbox backends running dovecot v2.2.18 on SLES11p3 with mail_location pointing to a glusterfs-mountpoint (GlusterFS: v3.6.3) * mailbox01.example.de: 10.0.2.21 * mailbox02.example.de: 10.0.2.22 * mailbox-gluster.example.de points as an A-RR to 10.0.2.21 and 10.0.2.22. My problem: With LMTP everything works fine (thanks for this!). The director sets the "host" field correctly and all delivery attempts work fine to the estimated backend servers. But when I try to connect via IMAP-/POP3-client (through proxy or direct) it fails with following log messages. It seems, that the director doesn´t set the host field within IMAP/POP sessions before proxying!? auth: Debug: auth client connected (pid=46359) imap-login: ID sent: x-session-id=V3iJmU4biAAK/BAa, x-originating-ip=10.0.0.26, x-originating-port=54408, x-connected-ip=10.0.1.151, x-connected-port=143, x-proxy-ttl=4: user=<>, rip=10.0.1.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> auth: Debug: client in: AUTH 1 PLAIN service=imap session=RVnAm04bzwAK/FCX lip=10.0.2.21 rip=10.0.1.151 lport=143 rport=54735 resp=<hidden> auth: Debug: ldap(tester(a)example.de,10.0.1.151,<RVnAm04bzwAK/FCX>): bind search: base=o=example,c=de filter=(&(|(uid=tester@example.de)(mail=tester@example.de))(!(<cut-cut-cut>)) [...] auth: Debug: client passdb out: OK 1 user=tester(a)example.de director_proxy_maybe=yes lip=10.0.2.21 lport=143 proxy pass=<hidden> imap-login: Debug: Ignoring unknown passdb extra field: director_proxy_maybe imap-login: Debug: Ignoring unknown passdb extra field: lip imap-login: Debug: Ignoring unknown passdb extra field: lport imap-login: Error: proxy: host not given: user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> imap-login: Disconnected (internal failure, 1 successful auths): user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> Finally the output of "doveadm proxy list" is empty! "doveadm director map" output after a successfull LMTP delivery attempt (before: doveadm director flush all): user hash mail server ip expire time tester(a)example.de 856838019 10.0.2.21 2015-07-20 15:49:18 "doveadm director map" output after a failed IMAP session attempt (before: doveadm director flush all): user hash mail server ip expire time tester(a)example.de 856838019 10.0.2.21 2015-07-20 15:50:02 So, director seems to work in this constellation, but only for LMTP and not for IMAP/POP Proxy :( Has anybody configured this before?

Helper to open "/doc/wiki/.." paths; suggestions
by Christian Jaeger 18 Jul '15

18 Jul '15

I wrote this script to have an easier time looking at the doc paths referenced from the default configuration files (currently using dovecot in Debian oldstable). Feel free to include in the distribution or wherever. Probably a better solution would be to publish the config files with the paths already expanded to the online URL, or a local filesystem path that works (in the latter case, I'd wish the docs would be bundled in html format). I wonder whether to approach the debian maintainer about this or the Dovecot team? Definitely something for the maintainer is to put the bundled docs in a place where I would have expected it (/usr/share/docs/dovecot/wiki/ instead of /usr/share/docs/dovecot-core/dovecot/wiki/, or a dovecot-doc package, also, links or mentions from the doc dirs of all dovecot packages to the docs). Also, I think there should be a README document that serves as the first introduction of the user to how to configure the system: how are the config files split up, what does "!include" mean (why the "!"? Is it a comment char?), other rules on the config file format. I.e. the basics to enable the new user to go about reading the current config and where to find further docs/help. Thanks & Cheers, Christian.

Getting duplicated mails while using imapc and dsync
by Michael 17 Jul '15

17 Jul '15

Hello list, currently I'm migrating our old mailserver to a new mail architecture that is based on a master-master dovecot setup (two machines). The replication actually works but I'm also syncing our mails from the current mailserver via imapc on a regular schedule. For some reason I've in most (but not all) imapc-synced mailboxes duplicated emails that I also can't deduplicate with doveadm. I've also set up test-mailboxes that I don't sync with imapc and in those I don't have any duplicated mails. My command to sync the mails from the old host to the master-master system looks as follows: doveadm -o imapc_user=$i*dovemig -o imapc_password=<password> -o imapc_host=<oldhost> -o imapc_features="rfc822.size fetch-headers" -o mail_prefetch_count=20 -v -D sync -R -u$EMAIL imapc: &> $LOGS/$i.log So, is this actually the wrong approach to sync mails from the old host to the new one or is it just not recommended to sync them over-and-over again in such a setup via imapc or is it better to sync them only once? Any hint/pointing me to the right solution is greatly appreciated. Michael

Dovecot-EE repository for Debian 8 (Jessie/stable)
by Bernhard Schmidt 17 Jul '15

17 Jul '15

Hi, are there plans to support Debian 8 (alias stable, alias jessie) in the dovecot-ee repository? Currently there are only squeeze and wheezy repos. The wheezy repo is uninstallable due to an unsatisfyable dependency on libicu48. Of course you can install libicu48 from Wheezy on a Jessie system, but this will break security updates and might not be the best idea for a library like that. Bernhard
