[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. Do i need symlinks, or what I have to do after create the folder + permissions? cu denny

[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
by Timo Sirainen 25 May '10

25 May '10

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.
