[Dovecot] acls not copied when creating subfolder of private INBOX
by Andreas Helmcke 09 May '12

09 May '12

Using brand new dovecot 2.1.5 I still have a problem with the inheritance of acls. Setting: - maildir with private INBOX and public folders. - users maildir directory (/home/mail/user/ahelmcke) contains dovecot-acl file - public folders root directory (/home/mail/Fax) contains dovecot-acl file When creating a subfolder of the public folder the dovecot-acl files gets copied to the subfolders directory as expected. When creating a subfolder of the users INBOX the dovecot-acl files does /not/ get copied to the subfolders directory.

Re: [Dovecot] Dovecot for POP3S proxying

Dovecot is installed but actually I just use auth module (for postfix authentication). In your dovecot.conf example, I don't see the "proxy" command ? Could you give me a few more details on the "proxy" command usage (ExtraFields/Proxy is not clear for me)?

If you already have dovecot running in proxy mode it's easy to add pop3s. If not, see http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy See http://wiki2.dovecot.org/Services search the page for pop3s. A simple example: ssl = yes ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/dovecot.pem service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } Of course there is a lot more SSL tuning that can be done: http://wiki2.dovecot.org/SSL/DovecotConfiguration > -----Message d'origine----- From: David Jonas > Sent: Wednesday, May 02, 2012 10:29 PM > To: Gilles Albusac > Cc: dovecot(a)dovecot.org > Subject: Re: [Dovecot] Dovecot for POP3S proxying > > On Wed May 2 06:41:00 2012, Gilles Albusac wrote: >> I would like to configure Dovecot for POP3S proxying all users from >> the Internet to the internal Exchange Mail Server. > > Unless I'm missing something with your request, you don't need dovecot. > Any ssl proxy can do that for you, such as stunnel > (http://www.stunnel.org/) We use the hardware ssl termination on our > load balancers for pop3s, imaps, and smtps.

[Dovecot] IMAP NOTIFY extension
by ashley willis 09 May '12

09 May '12

your work on NOTIFY was brought to my attention, and I see it hasn't been changed in two months, a week after you announced it. a few users and some mail admins have been wanting something like this for k9 mail, which I help develop. what is the current status? is it worth installing and starting work in getting k9 to support it yet? I'd offer help on your end, but I just know java and perl. c code usually confuses me (i keep meaning to learn, but...). thanks! -ashley -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

[Dovecot] courier to dovecot
by Grafibit Rendszergazda 08 May '12

08 May '12

Dear All, I know there were many threads on this topic. I was searching the archive and the net also, but did not find a solution on my problem. I hope you can help me. I am migrating from an old server using courier to a new server with dovecot and i can not manage to have the same uids after the migration. After copying the message files from the old server to the new, and executing the script from the wiki page the messages are still re-downloaded by the mail clients. After telnet and logging in to the old server port 110, I got the following on the command *uidl*: 1 UID377-1278276092 2 UID387-1278276092 3 UID394-1278276092 4 UID498-1278276092 5 UID499-1278276092 6 UID564-1278276092 On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems for me that the old server is using the same uidl format. Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive --convert /command or i don't the uidls on the new server won't be the same. Both the %u and %v numbers are differ. Please give me any hints how to continue the investigation to have a successful migration.

Yes, that's possible. The IMAP/POP3 servers behind Dovecot director wouldn't even need to be Dovecots at all. Although you really want to use v2.1 director since it has a lot of fixes compared to v2.0.

[Dovecot] Panic in index-sync.c: line 25 on dovecot-1.2.17
by Leon Meßner 07 May '12

07 May '12

Hi, with dovecot-1.2.17 (yes i know it's old) i'm getting the folowing error after doing a system upgrade. May 7 22:04:26 mail dovecot: deliver(elon): Panic: file index-sync.c: line 25 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) May 7 22:04:27 mail kernel: pid 79989 (deliver), uid 4873: exited on signal 6 (core dumped) this only happens to one user and only with mail from one mailinglist (this one). Mails do get filtered by sieve. After some delivery attempts the mail finaly gets stored alright in the maildir. May 7 22:23:27 mail dovecot: deliver(elon): sieve: msgid=<assp.047487a390.4FA82AA5.60907 09(a)amfes.com>: stored mail into mailbox 'dovecot' May 7 22:23:27 mail postfix/local[82289]: 7DED511402: to=<elon(a)physik.tu-berlin.de>, orig_to=<l.messner(a)physik.tu-berlin.de>, relay=local, delay=1141, delays=1141/0.01/0/0.26, dsn=2.0.0, status=sent (delivered to command: /usr/local/libexec/dovecot/deliver) May 7 22:23:27 mail postfix/qmgr[1303]: 7DED511402: removed After that a new mail does the same dance (perhaps until the next one to this ML arrives). The maildirs are on NFS and in this case only beeing used with my instance of mutt and two other postfix+dovecot servers which are quite idle. Whats the way to debug this ? Thanks, Leon

[Dovecot] Proxying for some users and having the rest local?
by Dr Josef Karthauser 07 May '12

07 May '12

I'm migrating a load of mailboxes from cyrus to a new dovecot server. What I'd like to do is to switch the DNS to dovecot, and set things up so that all old imap mailboxes are accessed through the dovecot proxy. That way I can migrate them one at a time independent of DNS issues. I've got a load of users specified in mysql, and that configuration works well for local mailboxes. How do I configure things so that I can switch proxy access on and off? What's I've got so far is: password_query = SELECT user, domain, password, "masteruser" as master, "masterpass" as pass, proxy, "remoteimap.server" as host FROM mailboxes \ WHERE user = '%n' AND isMailbox AND active AND domain = '%d' I imagined that I could switch the proxy per user by setting proxy='n' or proxy=null for any users that want to be local, and proxy='y' for any users that I want to forward on to the original server. It doesn't appear to work that way though. Irrespective of the proxy value dovecot appears to try and proxy all users. What am I doing wrong? I can't work it out from the docs, and the source will take quite a bit of studying to get to the bottom of it all. Thanks :), Joe

[Dovecot] Authentication process holding open filehandles
by George Barnett 07 May '12

07 May '12

Hi, We're using dovecot to provide pop3 for a number of mailboxes. The setup is pretty simple: Each user / domain has a mailstore in /data/mailstore/<domain>/<user>/Maildir (backed by NFS). Passwords are in simple passwd-file format in the top level domain directory eg: # cat /data/mailstore/foo.com/.passwd user:{plain}password The passdb setup looks like this. passdb { args = username_format=%n /data/mailstore/%d/.passwd driver = passwd-file } The problem we're having is that when we want to remove a domain from the system and we go to rm -rf /data/mailstore/<domain>/ we are unable to because the auth process is still holding onto the file handles for the password file. Can somebody suggest an alternative pattern that I could use for storing password files? Ideally, we'd avoid one large file to prevent locking issues and would also keep the passwd-file setup since it's simple. It would be possible to have the password files in a separate dir, but over time I'm guessing that would lead to nfs turds? Easy to clean up I suppose, but maybe there's a simpler solution I'm missing? George

[Dovecot] Shared INBOX change in v2.1.6?
by Timo Sirainen 04 May '12

04 May '12

Previously Dovecot has shown shared INBOX like: * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/INBOX" * LIST (\HasNoChildren) "/" "shared/tss2/foo" The last change in hg makes it return simply (same as with Cyrus): * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/foo" This behavior could be made optional, but does anyone actually want it to work the old way (and why)? I'd rather not add an option that isn't useful to anyone. I think older Dovecot versions have allowed opening both shared/tss2 and shared/tss2/INBOX, but at least in v2.1 that code was broken. With the last change it's still possible to open both of them, the shared/tss2/INBOX just isn't visible in LIST output.

It seems that dovecot just hung up on postfix. (side note: no, can't use xclient in nginx/postfix. But perhaps soon.) After much digging I thought I solved it with: login_trusted_networks = 172.20.20.0/24 mail_max_userip_connections = 0 This seems safe enough because dovecot is only providing sasl to postfix, no connections to the outside world. But the error is still happening. # doveadm penalty IP penalty last_penalty last_update 172.20.20.61 1 2012-04-30 19:15:56 19:15:56 strace on the anvil process shows a lot of GETs and INCs: 18:54:06 read(14, "PENALTY-GET\t172.20.20.61\n", 397) = 25 <0.000016> 18:54:06 write(14, "1 1335837245\n", 13) = 13 <0.000029> A two minute survey showed penalty distribution: 0: 60% 1: 15% 2: 18% 3: 8% Finally I just disabled penalties with the info from http://www.dovecot.org/list/dovecot/2011-December/062631.html and that seemed to do it. Is there a better way? This took me a long time to run down so I tried to make this message detailed enough that others with similar problems will stumble upon it.

[Dovecot] doveadm mailbox: rc=0 on error
by Andreas Schulze 04 May '12

04 May '12

Hi all, I use "doveadm mailbox mutf7 -7 $folder" to convert imap foldernames to UTF-8. If $foldername is not mUTF-7 encoded, doveadm returns "doveadm(root): Error: Mailbox name not valid mUTF-7: $folder" This errormessage is printed on stderr but the returncode of doveadm is zero. I tested with dovecot-2.0.* and dovecot-2.1.* # all right: $ doveadm mailbox mutf7 -7 'gr&APw-n'; echo $? grün 0 # also all right, no mUTF-7 encoded folder: $ doveadm mailbox mutf7 -7 'gruen'; echo $? gruen 0 # wrong $ doveadm mailbox mutf7 -7 'grün'; echo $? doveadm(root): Error: Mailbox name not valid mUTF-7: grün 0 Would be nice if doveadm exit with an errorcode != 0 in that case.

[Dovecot] Strange behaviour for sieve_before
by Simone Caruso 04 May '12

04 May '12

Hi all, i moved from dovecot 2.0.15 (lda) to 2.1.5 with lmtp transport, all works well with the same configuration directives. But sieve_before stopped working with mail_debug=no. The weird thing is that, with mail_debug=yes the sieve_before script starts working. Any idea? Thanks (my conf attacched, for the new install i used prebuild packages) -- Simone Caruso IT Consultant +39 349 65 90 805

[Dovecot] Sieve script does not run in dovecot 2.0 on squeeze
by Victor Oñate 03 May '12

03 May '12

Hi, I want to use Sieve filtering with my Dovecot 2.0.20 installation on Debian squeeze.

I use LDAP to delivery the mail. any idea. Thank you. Th. Victor Oñate

[Dovecot] mdbox corruption
by Daniel L. Miller 02 May '12

02 May '12

I have isolated the corruption in a mailbox to 4 mdbox files. Two of these (smaller) files cause the force-resync to report a breakage and save the file as m.XX.broken. The other two (larger) files cause a crash. Is there a way I can fix these files and recover the mails? -- Daniel

[Dovecot] dovecot, ldap and multiple auth_bind_userdn
by Cédric Jeanneret 01 May '12

01 May '12

Hello List! I'm having some troubles for a client of mine: he has two ldap branches which may contain valid users for imap login... For now, dovecot is configured so that it uses the auth_bind: ======== uris = ldap://localhost:389/ auth_bind = yes auth_bind_userdn = uid=%u,ou=user,dc=org ldap_version = 3 base = dc=artemis user_attrs = user_global_uid = 8 user_global_gid = 8 pass_attrs = uid=user ## other options user_filter = (uid=%u) pass_filter = (uid=%u) default_pass_scheme = CRYPT ======== Unfortunately, I cannot manage to tell him "hey guy, uses those two branches": uid=%u,ou=user,dc=org and uid=%u,ou=external,dc=org Is there a special way to do that ? Is it even possible ? I cannot modify the ldap tree, so this option is out, unfortunately :(. My dovecot version: dovecot --version 1.2.15 Thanks in advance for your answers. Cheers, C.

[Dovecot] question dovecot Inheritance global acl vs userfolder acl
by Robert Schetterer 01 May '12

01 May '12

Hi Timo my tests resulted in inheritance is given if a userfolder has set some acl to its new created subfolder , which is nice if some userfolder has its acl from global acl there is no inheritance to its new created subfolders, that subfolders will always created with full owner rights i am not really sure if its a good idea to have inheritance from global acl and if its hackabel what is your idea to this ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] SETANNOTATION for Dovecot
by Dieter Knopf 01 May '12

01 May '12

Hello, i'm using kmail2 and for Folder Settings the SETANNOATION command is needed. Is there any way to add this command to Dovecot? I already found a dovecot-metadata-plugin but there is no Package available for Debian. Thanks Dieter

[Dovecot] restoring mails and directories
by oni-neko＠gmx.net 01 May '12

01 May '12

Good day! is there an easy way to restore e.g. deleted mails and/or mail directories? let me specify: I'm running dovecot 1.2.9 on a current ubuntu lts. It is set to Maildir and I backup the folder with the users maildata nightly via rsync. now, when someone deletes a mail that they still need, and I copy it back from the backup, it will not be visible to mail clients. When I change the mailfile by a letter or so, it shows. that's easy enough, if not exactly awesome ;-) But, if said person deletes a whole folder of mails, this way to make restored mails show up becomes rather unreasonable. surely there is a better way to do this? I'd be glad for any and all hints! =) best regards silvana -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Dovecot dsync mail replication issues
by Reuben Farrelly 01 May '12

01 May '12

Hi, I'm trying to set up some dsync based replication between two hosts on my network. The current topology is a single server running Postfix with a single dovecot installation with a Maildir per user (only 4 users including myself). No NFS, just local system users on ext4. I am only using system users, ie no virtual users. I am using dovecot deliver to deliver mails into the Maildir's. This - being a very standard Maildir installation - all works just fine. I'm running dovecot-2.1.5 (release versions) x86_64 with Gentoo on both hosts and using key based ssh to transport the data using the root login. What I would like to do is extend the design so as to replicate the Maildirs across a second machine and in the future be able to connect via IMAP into either machine to sync mail. Two way dsync would be rather cool because I could then deliver via SMTP to either system and have changes automagically propagate - but initially just simple replication would be a good start. I was hoping that dsync would allow me to do this, but I've run into quite a number of problems while getting this to work. http://dovecot.org/list/dovecot/2012-March/064243.html ...was very useful and I've based my config on that. Initially I've tried to sync up the user Maildirs, and this has more or less worked: doveadm sync -u lyn remote:root@dustbowl.reub.net This succeeds without error on the initial sync. However if I try to run the re-sync again (such as a use case of if the sync of another Maildir takes 4 hours so I want to resync up the earlier ones again) I end up with a mysteriously named INBOX folder in both the source and destination Maildirs: drwx------ 5 lyn lyn 4096 Apr 30 19:32 .INBOX_7a86a62d465a974fb92f00003b258734 It has the basic structure of a Maildir but is empty in terms of mails: drwx------ 2 lyn lyn 4096 Apr 30 19:32 cur -rw------- 1 lyn lyn 220 Apr 30 19:32 dovecot.index.log -rw------- 1 lyn lyn 51 Apr 30 19:32 dovecot-uidlist -rw------- 1 lyn lyn 0 Apr 30 19:32 maildirfolder drwx------ 2 lyn lyn 4096 Apr 30 19:32 new drwx------ 2 lyn lyn 4096 Apr 30 19:32 tmp First question: why is this random named directory being created in the origin Maildir? Shouldn't the replication be more or less read-only in the origin Maildir? Second question: If I re-attempt a doveadm sync a second time I get this error: tornado Maildir # doveadm sync -u lyn remote:root@dustbowl.reub.net dsync-local(lyn): Error: Can't rename mailbox INBOX_7a86a62d465a974fb92f00003b258734 to INBOX: Target mailbox already exists dsync-local(lyn): Error: Can't rename mailbox INBOX to INBOX_eb15f30ea563be4b703200002bd68bb1: Renaming INBOX isn't supported. tornado Maildir # It's not clear if the second attempt has failed or succeeded, and it's a bit odd that it errors out on a directory that the dovecot sync process itself has created. Third question: Upon starting Dovecot lots of ugliness is logged in the mail log: Apr 30 19:44:59 tornado dovecot: master: Dovecot v2.1.5 starting up (core dumps disabled) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: user mozsync: Initialization failed: Namespace '': mkdir(/var/www/xxx/server-full/Maildir) failed: Permission denied (euid=1016(mozsync) egid=1016(<unknown>) missing +w perm: /var/www/xxx/server-full, dir owned by 0:0 mode=0755) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: sync: User init failed Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Warning: I/O leak: 0x414190 (line 102, fd 16) Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: remote: doveadm(cisco): Fatal: User doesn't exist Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: read() from worker server failed: EOF Users mozsync and cisco are not valid mail users and it's not appropriate that Dovecot tries to create a Maildir for either of them. The users are system unprivileged users only, and do not ever send or receive mail. And - I/O leak? ;) Also, user cisco is local to one box only, and does not exist (nor does it need to) on the remote host. So any complaints about this user are invalid and dovecot needs to ignore replication for this user anyway. Fourth question, upon starting dovecot again, mail.log then spews several hundred of these messages: Apr 30 19:45:06 tornado dovecot: dsync-local(reuben): Error: msg-get failed: box=Trash uid=114863 guid=1335382569.M98089P29952.tornado,S=6479,W=6625 Before aborting entirely with: Apr 30 19:45:09 tornado dovecot: imap: Server shutting down. in=328 out=2042 It seems to me that a a few of those problems logged could be solved by being able to specify which system users to synchronise, rather than Dovecot making a blind assumption that all users actually have valid Maildirs that need to be created, and all need to be sync'd between two hosts. Subsequent delivery based sync'ing fails silently (pending more investigation) but I'd like to try and fix the above listed problems first before worrying about the later stages of the sync not working. Has anyone else run into these problems or found better ways of making this type of setup all work? Thanks, Reuben

[Dovecot] Sieve doesn't find user scripts

Hi, I want to use Sieve filtering with my Dovecot 1.2 installation on Debian squeeze. I have a virtual domain setup using Portgresql. ManageSieve works fine so far, I can edit and activate/deactive scripts (using Thunderbird + Plugin) and they show up in the filesystem where I expect them to be, see below. The problem is that LDA doesn't find the script.
