[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
