[Dovecot] A few questions on shared folders
by Michael Durket 26 May '10

26 May '10

I'm looking at the possibility of using shared folders to solve a particular problem for my employer and I have a few questions: 1) Can shared folders be in mbox format while allowing the user's mail to be in maildir format? (I think the answer is yes, but wanted to check). 2) What version of dovecot should I be running in order to support shared folders? 3) Is there a good overview document that people could recommend I read that describes how best to set up shared folders under dovecot (and perhaps also gives an overview of shared folder usage in IMAP mail clients in general)? Thanks very much, Michael Durket

[Dovecot] STARTTLS does not seem to work
by Phil Howard 26 May '10

26 May '10

I believe I have the configuration set to use START TLS on IMAP4 (143) and POP3 (110) ports. However, it does not seem to be working. Yet "STARTTLS" is listed as a capability (which tells me I probably do have it configured right). In the session below, 172.30.0.24 is the mail server I'm putting up. 64.26.60.229 is an outside mail service. A similar thing happens on POP3. The always-SSL/TLS ports (993 and 995) are working. There's very little documentation matching "starttls". ======================================================================== altair/phil /home/phil 162> telnet 172.30.0.24 143 Trying 172.30.0.24...

[Dovecot] config file includes
by Tim Traver 26 May '10

26 May '10

Hi all, ok, I couldn't quite find this in any of the documentation, so I figured I would ask here. In preparation to move to version 2.0 to take advantage of the mutiple IP and SSL cert options that are coming, it would be really nice to be able to include other config files in the main config file, so that I don't have to edit the main config in order to add new IP addresses or certs... Does dovecot currently have the ability to include another config file when it is parsing the main config??? If not, is that something that we can put on the wish list? Thanks, Tim.

[Dovecot] Problems with the fs-quota plugin on delivery stage
by Kostik 25 May '10

25 May '10

Hi All! Just noticed a strange behavior of the FS quota plugin on delivery stage. We use group FS quotas via NFS. And quota-tool says: --- Disk quotas for group #5751796 (gid 5751796): Filesystem blocks quota limit grace nfse:/export 1276 10240 10240 --- I run: --- cat ./test.eml | /usr/local/libexec/dovecot/deliver -e -n -d xxxx(a)xxxxx.xxxx --- and get: --- Quota exceeded (mailbox for user is full) --- But ./test.eml is 7088147 bytes and it is not above the quota. dovecot debug log is: --- May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota block device = nfse:/export May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota mount point = /mount/m5 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: host=nfse, path=/export, gid=5751796, bytes May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: gid=5751796, value=8409088, limit=10485760, active=1 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): from=<xxxx(a)xxxxx.xxxx>, msgid=<4BEA4744.1040701@xxxx@xxxxx.xxxx>: save failed to INBOX: Quota exceeded (mailbox for user is full) --- It seems that "value=8409088, limit=10485760" shows that the quota is no problem, but "save failed". If I become that user, then no problems. I can copy ./test.eml without problems. Now quota-tool says: --- Filesystem blocks quota limit grace nfse:/export 8212 10240 10240 --- If I try to copy again(over quota), then honestly get: --- cp: closing `./test2.msg': Disk quota exceeded --- If I switch off quota plugin on dovecot.conf (LDA specific settings), then: - 1. The first delivery is without error, but the INBOX is corrupted(last msg is clipped) but quota-tool show only 3300 blocks used (quota is 10240 blocks). - 2. Following delivery big msgs (over quoted) ends with an error: "Not enough disk space" (this is correct, because the quota is really ended) - 3. Following delivery small msgs (above quoted) ends well, msgs are delivered (used 3304 blocks and etc.) Our setup: -- slackware 11.0, x86_32 -- linux 2.6.31.6 -- dovecot 1.2.11 -- mailbox(not maildir) via NFS storage. Please, tell me where to start looking for the problem? =kostik

[Dovecot] (1.2.11): Confused about shared/public folders
by Denny Schierz 25 May '10

25 May '10

hi, i red several hours a lot of documentation (wiki, Blogs, lists ...) how to get public folders. Under cyrus it is very easy. Create a mbox on the top with cyradm and some acls. Nothing more ... All i want is: public/info public/group/internal public/foo public/foo/bla on info, everybody can read on group/internal - only group has full access to internal public/foo/bla - read write for everyone The flags (seen, ...) is stored for all. The wiki entries are to old or mixing several things and are not clear, what I should do, to get it working. my config: dovecot.conf mail_location = maildir:/imap/domain/%1n/%n:INDEX=/imap/indexes/domain/% 1n/%n namespace private { separator = / prefix = inbox = yes } #namespace shared { # separator = / # prefix = shared/%%u/ # location = maildir:/imap/shared/domain/%1n/% n:INDEX=mbox:/imap/shared/domain/%1n/%n # subscriptions = no # list = yes #} namespace public { separator = / prefix = public/ location = maildir:/imap/shared/domain subscriptions = no list = yes } mail_uid = vmail mail_gid = vmail mail_privileged_group = vmail protocol imap { login_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap-login mail_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap mail_plugin_dir = /usr/local/dovecot/dovecot/lib/dovecot/imap/ mail_plugins = quota imap_quota imap_idle_notify_interval = 120 fsync_disable = yes mail_plugins = quota imap_quota acl imap_client_workarounds = outlook-idle netscape-eoh } plugin { acl = vfile acl_shared_dict = file:/imap/rbg/acl/shared-mailboxes.db acl = vfile:/imap/rbg/acl/dovecot-acls } I wasn't able to use under plugins imap_acl, cause of errors: open(/usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so: symbol acl_mailbox_right_lookup: referenced symbol not found Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /usr/local/dovecot/1.2.11/etc/dovecot.conf System is Solaris10, build by my self with Sieve Patches. After changing to "acl" only, DoveCot starts. So, i can see in Roundcube (webmail) the folder Public (or shared, from the above example) but nothing more.

[Dovecot] order of variable modifiers
by Phil Howard 25 May '10

25 May '10

I'd like to have a variable substitute take the domain name part, lower case it, MD5 it, and take a 2-character substring of that. Would that be like %2MLd ? The documentation on the H hash modifier described reversing with R, but expresses it at %3RHu which seems to me like it would be reversing the hash result rather than the user string. I'm undecided about MD5 vs. hash, and could go either way. But I was thinking: mail_location = /data/mail/%2MLd/%Ld/%2MLn/%Ln

[Dovecot] per domain quota
by alex 25 May '10

25 May '10

Hi I'am using dovecot with quota_rule stored in mysql user table, and quota usage stored in mysql dict ###### Quota ############# dict { quotadict = mysql:/usr/local/etc/dovecot-quota.conf } plugin { quota = dict:user::proxy::quotadict quota_rule2 = Trash:storage=10%% quota_rule3 = Sent:ignore #quota_rule = *:storage=10M } ################################### Everything works as expected, but I have some inconveniences for domains with large number of mailboxes. Allocating and maintain quota to every account it's a hard job. I just want to implement some flexibility for this situations (ex the first enforcement to be the user quota and the second to be the domain quota). Is there a way to implement such thing in dovecot and what are the adjustments that I need to do. Regards Alex

[Dovecot] v2.0.beta5 released

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz.sig Sorry for being so quiet recently. Unfortunately I think it's still going to last a while longer. I'll be in Italy for next two weeks and immediately after that I'll move to Portugal. I'll probably write something about that later to blog. I had hoped that this beta5 would be almost the same as RC1, but I didn't have time to put everything there yet, and thought beta4 is way too old already. The few things that should still be done: - Change expire-tool to be a plugin for doveadm expunge command - doveadm mailbox * commands should use UTF-8 for mailbox names, not mUTF-7 (and add -7, -8 parameters to switch between them) - THREAD command seems to be crashing - some other bugfixes Some of the changes since beta4: - default_login_user is now "dovenull". You should create this user. - imap, pop3 -u <user> now does userdb lookup + changes privileges if necessary, so it's much easier to start imap/pop3 session for a specific user from command line - doveadm has all kinds of new commands and changes - PostgreSQL supports now multiple connections to backend. Also supports load-balancing / HA by specifying multiple host parameters. MySQL and PostgreSQL now share the same code for that. - probably lots of other things I can't think of right now. h

[Dovecot] about acl
by Yavuz Maşlak 25 May '10

25 May '10

I use dovecot, vpopmail. I wish to restrict a mail user's login to its mailbox according to its ip address. I don't wish other users to be affected . Namely, for instance, abc(a)domain.com can login to its mailbox from a few specific ip addresses but the same user will not able to login from anywhere. Meanwhile normally other mail users can login to their mailboxes from all ip addresses. How can I do that with dovecot acl ? any advice.

[Dovecot] suggestion
by Andreas Schulze 25 May '10

25 May '10

hello, dovecot2 implements "!include conf.d/*.conf" to build the configuration from multiple configfiles. So the settings for pop3, imap or lmtp may stay in different files. unfortunately the "protocol = " does not allow a += logic to enables or disable inet listeners. It would be nice to have protocols += imap in conf.d/imap.conf and protocols += managesieve in conf.d/managesieve.conf This would make the include feature more consistent... or is it already possible ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] Sieve problem. Timo, is this mbox file size limitation hard coded? If so, why?
by Stan Hoeppner 25 May '10

I would not have expected this upon implementing sieve. And I really need to get around this limitation. LDA has no problem writing to these large mbox files. Why does sieve have a problem with them? This is very odd.

[Dovecot] List shared folders
by Marcio Merlone 25 May '10

25 May '10

Good morning! I run an imap-only Ubuntu 8.04 mail server with dovecot 1.2 and pam_ldap, so all my users are posix users. No virtual user or domain, no sql so far. I am setting up shared folders with "namespace shared". I got no errors upon restarting the service, but I get no shared folders listing. As per the wiki http://wiki.dovecot.org/SharedMailboxes/Shared I can use a bdb file or sql connection to keep the listing. But when I use a single bdb file like: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } everytime a user logs in, this file get its ownership to the user with 0600 mode. I could use an sql dictionary, but since I dont have any sql params on my configs I am not sure where to store connection params like user, password and host for database. Can anybody help me with that? My goal is to allow my users to shared selected folders with other users, hope to be in the right path. Thanks and regards. -- Marcio Merlone

[Dovecot] Setting up ACL for IMAP
by Andrés Gattinoni 25 May '10

25 May '10

Hi guys, I just suscribed cause I'm trying to do something which I'm not sure how. I need to prevent some accounts from deleting there emails. >From what I've seen [0] this could be achieved by using ACL. My first question is, is this right? Is there a way to achieve the same using POP3? I tried setting up ACL using the info at the Wiki [1], but it's not working. What I've seen is that when I put: protocol imap { mail_plugins = acl imap_acl } I get the following error: May 14 14:54:52 mail dovecot: SIGHUP received - reloading configuration May 14 14:54:52 mail dovecot: imap dump-capability: Couldn't read capability (got 0 bytes) May 14 14:54:52 mail dovecot: Invalid configuration, keeping old one May 14 14:54:52 mail dovecot: child 32301 (unknown) returned error 82 (Internal logging error) Looking on the internet I found out that I don't have the imap_acl lib shared object.

[Dovecot] SSL Bug
by Matthew Sackman 25 May '10

25 May '10

Hi, After many hours of testing, I've finally tracked down the issue I have been having with dovecot's SSL support. The problem is that the SSL certs result in "TLS handshaking: SSL_accept() syscall failed: Connection reset by peer" errors *if the certificate granted is not granted for client use*. For servers, I normally generate SSL certificates specifically for servers: [ server_ca_extensions ] basicConstraints = CA:false keyUsage = keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.1 If you just do that, then the SSL certificate doesn't work in dovecot (it will work fine in Apache, or Postfix etc etc). You also need the certificate to be valide for client side work: [ client_and_server_ca_extensions ] basicConstraints = CA:false keyUsage = digitalSignature, keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.2, 1.3.6.1.5.5.7.3.1 I believe this is a fault with Dovecot. This is with the Debian package for Dovecot 1.2.11 (Version: 1:1.2.11-1). The default self-signed certificate the Debian post-install script generates pops out a certificate that is valid for everything, which is why it works by default out of the box. Matthew

[Dovecot] Plugin to encrypt mailboxes ?
by Frank Bonnet 25 May '10

25 May '10

Hello Is there a possibility for my users to encrypt their mailboxes through Dovecot ? They haven't direct access to the server, IMAP & IMAPS only. We use Thunderbird as client and mailboxes are in MBOX format Dovecot is running on a FreeBSD 7.2 server. Thanks a lot
